Chevrolet Caprice Police Patrol Vehicle (2011)

An all-new Chevrolet Caprice Police Patrol Vehicle (PPV) will join the ranks of law enforcement departments across North America in 2011. It's a modern, full-size, rear-drive sedan that will offer both V-8 and V-6 engines, as well as a host of specialized equipment and features.

Chevrolet made the announcement at the annual International Association of Chiefs of Police convention, in Denver, Colorado. The Chevrolet Caprice PPV will be available for ordering next year and will hit the streets in early 2011.

"The new Chevrolet Caprice police car is the right tool at the right time for law enforcement," said Jim Campbell, general manager for GM Fleet and Commercial Operations. "We asked for a lot of feedback from our police customers, which helped us develop a vehicle that is superior to the Crown Victoria in key areas."

Vice President, Global Chevrolet Brand Brent Dewar added, "Along with Impala and Tahoe, the Caprice Police Patrol Vehicle gives agencies a greater range of choices for police and special service vehicles that are all available from Chevrolet."

Unlike other police cars on the market, the Chevrolet Caprice PPV is not based on existing "civilian" passenger-car model sold in North America. It has been developed in key areas specifically for police duty, containing modern equipment and features:
Powerful 6.0L V-8 with fuel-saving Active Fuel Management technology and E85 capability delivers expected best-in-class 0-60 acceleration (sub six seconds) and top speed; a V-6 engine will also be offered, beginning in the 2012 model year
Optional front-seat-only side curtain air bags allows a full-width rear-seat barrier for greater officer safety
Two trunk-mounted batteries, with one of them dedicated to powering various police equipment
Designed for five-passenger seating, meaning the upper-center section of the dashboard can be used for equipment mounting without the concern of air bag deployment interference
Compatibility with in-dash touch-screen computer technology
Special front seats designed for the long-term comfort of officers whose car is their effective office, including space that accommodates the bulk of a typical equipment belt.

The front seats are sculpted to "pocket" the equipment belt, which greatly increases the comfort for a great range of police officer sizes. The foam density of the seatback and cushion insert surfaces are designed to conform to the shape of an equipment belt's various items, too, allowing the officer's back to rest properly on the seatback surface.

"The Chevrolet Caprice Police Patrol Vehicle's seats represent a revolution in comfort and utility for officers who spend long hours in their car," said Bob Demick, lead seat design manager. "The shape also enhances entry and egress, making it easier for officers to exit the vehicle quickly. The seatback bolsters, for example, have been purposefully contoured to help pocket the equipment on the belt, which includes the gun, Taser and handcuffs, which rest comfortably in the sculpted lower bolsters. That also increases the longevity of the trim cover surface."

Along with comfort, the materials used in the seats were also carefully selected. High-wear materials were chosen to stand up to long hours of everyday use, while breathability, long-term durability and ease of cleaning were also important criteria.

Engineers worked on several iterations of the seat, testing a couple of versions in the field to get real-world feedback from police officers, who used prototype seats in their cruisers for a month. Their input helped determine the final design.

Class-leading space
The Chevrolet Caprice PPV is based on GM's global rear-drive family of vehicles that also underpins the Chevy Camaro. It uses the longest wheelbase of the architecture - 118.5 inches (3,010 mm) - along with a four-wheel independent suspension that delivers responsive high-performance driving characteristics that are crucial in some police scenarios.

Chevrolet Caprice Police Patrol Vehicle's long wheelbase also contributes to exceptional spaciousness. Compared to the primary competition, its advantages include:
A larger interior volume - 112 cubic feet / 3,172 liters - than the Ford Crown Victoria, including nearly 4 inches (101 mm) more rear legroom
The barrier between the front seat and rear seat is positioned farther rearward, allowing for full front-seat travel and greater recline for officer comfort
At 18 cubic feet (535 liters) free space (beyond battery located in trunk), the Caprice's trunk volume is large enough to accommodate a full-size spare tire under a flat load surface in the trunk storage area.

The Chevrolet Caprice's 6.0-liter V-8 is rated at an estimated 355 horsepower (265 kW) with an estimated 384 lb-ft of torque. It is backed by a six-speed automatic transmission that is performance-calibrated for police duty. Additional, police car-specific powertrain and vehicle system features include:
High-output alternator
Engine oil, transmission and power steering coolers
Standard 18-inch steel wheels with bolt-on center caps
Large, four-wheel disc brakes with heavy-duty brake pads
Heavy-duty suspension components
Police-calibrated stability control system
Driver information center in the instrument cluster with selectable speed tracking feature.

A host of complementary features are also offered, including special equipment packages such as spotlights; lockouts for the power windows and locks; and an "undercover" street-appearance package (9C3).

To enable more room for interior equipment, the standard radio can be relocated to the trunk, allowing for an in-dash, touch-screen computer to be used.

Chevrolet Caprice on patrol: A brief history
Chevrolet's history with law enforcement is almost as old as the brand itself. Police departments have used Chevy sedans as police cars for decades, ordering them with basic equipment and powerful V-8 engines - including some special engines that weren't available in regular-production models, such as the 1959 Biscayne that was offered with up to 315 horsepower.

The full-size Chevrolets joined the force in 1976. All Chevrolet Caprice police cars - including the new, 2011 model - have carried the 9C1 order code. Here's a quick look back at Chevys on patrol:
1959 - Chevy Biscayne police model capable of 135 mph with specially tuned, police-only version of the 348-cubic-inch V-8 engine
1965 - The new "big-block" 396 engine is offered in Biscayne and Bel Air police cars, making them among the most powerful on patrol; a 427 V-8 was added in 1966
1976 - The 9C1 order code is given for the first time to a full-size Chevy police car package. It carries the Impala name.
1977 - The full-size Chevy is downsized. The 9C1 police package is retained, as is the Impala name.
1986 - The Caprice name replaces Impala, as the car is updated for the mid- and late-1980s - including the option of a powerful, 5.7-liter small-block V-8.
1991 - A new-generation Caprice is launched, with the 9C1 police car still on the beat.
1994 - The 260-horsepower (194 Nm) LT1 V-8 engine is offered in the Caprice 9C1, making it one of the fastest full-size police cars ever offered.
1996 - Caprice police car production ends, as GM's full-size, body-on-frame car architecture is discontinued.
2011 - The Chevrolet Caprice Police Patrol Vehicle returns to active duty.

The wait is over. After a seven-year hiatus, the new Chevrolet Camaro is now back in dealer showrooms.

Combining great looks, performance and advanced technology, the 2010 Camaro honors its heritage while delivering on customer expectations of a sports coupe for the 21st century.

"The new Camaro delivers a modern, advanced package of performance, comfort and technology," said Ed Peper, Chevrolet general manager and General Motors vice president. "It's a personal car for a generation of enthusiasts, both young and old, that honors the Chevrolet Camaro's heritage with a thoroughly contemporary design.

Built on the new global rear-wheel-drive passenger car platform, Chevrolet Camaro embodies GM's global vehicle development and design process. The original design concept was conceived in the United States, with engineering shared by both Australia and U.S. teams. Validation was conducted on roads throughout the world and assembly is handled by GM's award-winning plant in Oshawa, Ontario, Canada.

Design features 

With a design that is very close to the original concept, the 2010 Chevrolet Camaro acknowledges its heritage from the first-generation Camaro, produced from 1967 through 1969. The two-door sports coupe features classic proportions over a 112.3-inch (2,852 mm) wheelbase. The overall length of the Chevrolet Camaro is 190.4 inches (4,836 mm); width and height are 75.5 inches (1,918 mm) and 54.2 inches (1,376 mm), respectively.


The long hood and short deck are pushed to the far corners of the muscular fender forms and a fast, 67-degree rake windshield contributes to aerodynamic performance that includes a 0.37 coefficient of drag (Cd) on V-6 models and a slightly sleeker 0.35 Cd on the V-8-powered SS model.

Wheel arch openings received special attention through the design process. Whether the Chevrolet Camaro is equipped with the standard 18-inch, or optional 19-inch or 20-inch wheels, the relationship of the top of the tire and bottom of the fender is consistent on all models. All models also feature the classic "V" design motif in the nose, along with a 2.5-inch (63.5 mm) power dome in the aluminum hood, reminiscent of high-performance Chevrolet Camaro models. On SS models, a simulated air intake is located in the upper front fascia and the lower air intake is larger.

On the top, designers took a cue from Corvette and sculpted twin cockpits across the roof, giving the vehicle a distinctive Chevrolet presence. From the outside, the B-pillar is invisible to the eye, lending the true appearance of a hardtop coupe. The B-pillar is designed to provide increased structural rigidity to the car. And to ensure quality in the manufacturing process, a one-piece body stamping provides a cleaner overall side appearance that is free of seams, gaps or plastic appliqués. "Gills" located in the front of the rear quarter panel also are familiar Chevrolet Camaro styling cues.

Ten exterior colors are available and include Black, Victory Red, Rally Yellow and Silver Ice Metallic. Red Jewel Tintcoat is also available as an option. The color palette also includes Cyber Gray Metallic, Aqua Blue Metallic, Inferno Orange Metallic, White and Imperial Blue Metallic.

An RS appearance package is available on LT and SS. It includes HID headlamps with integrated halo rings, a rear spoiler on LT, specific taillamps and 20-inch wheels with a Midnight Silver finish.

Interior details 

Inside the four-passenger cabin, a well-executed balance of heritage, modern design and attention to detail conveys simplicity and refinement with contemporary details in the cluster, switches, dials and lighting. An available ambient light package, for example, offers advanced LED light pipe technology, giving the cabin a distinctive glow.

Deep, recessed gauges, located in square housings outlined in chrome, give a nod to the classic Camaro interior. The instrument panel gauges include both speedometer and engine rpm, with a driver information center located between the large gauges - its readouts and features controlled via a stalk on the steering column. An optional, console-mounted gauge package includes oil pressure, oil temperature, volts and transmission fluid temperature. The gauge package is included on 2LT and 2SS models.

Cloth upholstery is standard and leather-appointed seats are included on 2LT and 2SS models. Four-way manual adjustment including fore/aft and up/down on the driver seat and two-way adjustment on the passenger seat is standard. Heated, leather-trimmed seats with driver six-way power adjustment are optional.

Both LT and SS standard cloth and available leather interior colors are black, gray and beige. The front seat travel is a generous 8.5 inches (216 mm) from front to back. On SS models, the seats feature a distinctive SS logo on the headrest with contrasting stitching. An Inferno Orange interior trim package also will be available with leather interiors.

All models include a three-spoke steering wheel with manual tilt/telescope adjustment. Cruise control and rear defog also are standard, while a leather-wrapped steering wheel and shift knob; redundant steering wheel controls; Bluetooth and USB port are part of the available Driver Convenience and Connectivity package. Also included in the package is remote start on automatic transmission-equipped vehicles, as well as a personal device interface module for iPods.

Soon after production begins, customers will be able to order a short-throw Hurst shifter that provides quick, concise shifting.

Chevrolet Camaro's entertainment systems include a single-CD radio with six speakers that is standard on LS, LT and SS models. A premium, 245-watt Boston Acoustics nine-speaker audio system can be ordered on 1LT and SS models. XM Satellite Radio is standard on all models.

All models also include power door locks and express up and down driver and passenger window. Cargo capacity can be increased with the standard fold-down rear seat. The capacity of the trunk is 11.3 cubic feet (320 liters).

Safety 

The Chevrolet Camaro offers a comprehensive system of safety features - starting with a robust body structure and integral safety cage around the passenger compartment. High-strength steel and ultra high-strength steels are used in key areas throughout the structure. Safety technologies also include:
Driver and front passenger dual-stage air bags 
Driver and front passenger seat-mounted thorax side-impact air bags 
Head curtain side-impact air bags for front- and rear-seat occupants 
Front-seat safety belt load limiters and pretensioners 
A front passenger detection system that senses children and small-stature adults, and suppresses air bag deployment when appropriate. 

In both doors, an interlock pin is utilized to prevent intrusion into the passenger compartment and adds stiffness to the door structure by engaging with a clevis bracket set into the rocker panel.

Powertrains

When it comes to performance, the 2010 Chevrolet Camaro delivers in unexpected ways. An advanced 3.6L direct-injected V-6 with variable valve timing is standard on LS and LT models. It offers power and efficiency, with 304 horsepower (227 kW) and EPA-rated 29 mpg in highway driving.

The performance-oriented Chevrolet Camaro SS offers a pair of 6.2L V-8s, including one with Active Fuel Management that helps improve fuel economy by shutting down four cylinders during certain light-load driving conditions. That model delivers 25 mpg in EPA-rated highway fuel economy.

Indeed, the surprising fuel economy of the new Chevrolet Camaro enhances the driving experience. LS and LT models are EPA-rated at 18 mpg in the city and 29 on the highway with an automatic transmission; and 17 city and 29 highway with the manual transmission. Chevrolet Camaro SS with an automatic is rated at 16 city and 25 highway; and 16 city/24 highway with the manual transmission. Notably, none of Chevrolet Camaro's models is subject to federal gas guzzler taxes.

For comparison, the more expensive 2009 Dodge Challenger SRT8 offers comparable horsepower to the Chevrolet Camaro SS with the manual transmission - 425 (317 kW) vs. 426 (318 kW) - and is EPA-rated at 14 city and 22 highway. When automatic-equipped models are compared, the Chevrolet Camaro wins again, with the Challenger SRT8 rated at 13 city and 19 highway.

All of Chevrolet Camaro's engines channel their power to a responsive chassis that features independent front and rear suspensions, large, four-wheel-disc brake systems with standard ABS and GM's StabiliTrak electronic stability control system.

3.6L direct injection V-6 

Chevrolet Camaro's 3.6L direct injection (DI) V-6 delivers more power through increased efficiency, while maintaining fuel economy and lowering emissions - including a 25-percent drop in cold-start hydrocarbon emissions. Direct injection optimizes fuel delivery to the combustion chamber by introducing fuel closer to the combustion chamber. The fuel injectors are located beneath the intake ports and fuel is injected directly into the cylinder. The result is better efficiency in the combustion process leading to increased fuel efficiency at part and full throttle.

The 3.6L DI engine produces 304 horsepower (227 kW) at 5,900 rpm and 273 lb.-ft. of torque (370 Nm) at 5,200 rpm. Its 60-degree cylinder block and cylinder heads are cast aluminum to help reduce mass. A forged steel crankshaft provides optimal strength in the bottom end. The cylinder heads include four valves per cylinder, with a dual overhead camshaft design incorporating infinitely variable cam phasing.

A full dual exhaust system, with dual catalytic converters, helps reduce back pressure for optimum power. It also helps the engine reach operating temperature quicker to help burn off cold-start emissions. And despite a compression ratio of 11.3:1, the 3.6L DI engine is designed to run on regular gas.

Chevrolet Camaro SS's 6.2L powertrains 

Two 6.2L V-8 engines are offered in the Chevrolet Camaro SS, including the new L99 on automatic-equipped vehicles and the LS3 on manual-equipped models. Both engines are derived from the LS3 that debuted on the 2008 Chevrolet Corvette.

The 90-degree V-8 includes an aluminum block (with cast iron cylinder liners) and aluminum cylinder heads. The bottom end of the engine includes a new structural cast aluminum oil pan, with an oil capacity of 8.9 quarts (8.5 liters), while the two-valve cylinder head design is based on race-proven airflow dynamics. The intake valves measure 2.16 inches (55 mm) and exhaust valves are 1.60 inches (40.5 mm) in diameter.

The 6.2L engines also use a roller lifter-style camshaft with 5-percent greater intake-side valve lift than the Corvette's LS3. It manages airflow that is channeled through an acoustically tuned intake manifold with a composite design that reduces runner-to-runner variation. The throttle bore diameter is 90 mm.

Horsepower for the L99 is 400 (298 kW) at 5,900 rpm and torque is 410 lb.-ft. (556 Nm) at 4,300 rpm. The LS3 develops 426 horsepower (318 kW) at 5,900 rpm and 420 lb.-ft. (569 Nm) at 4,600 rpm (all numbers are SAE certified). Output on the L99 is lower than the LS3 because of a slighter lower compression ratio (10.4:1 vs. 10.7:1) and design features of the Active Fuel Management System. The L99 is paired exclusively with an automatic transmission.

As with the 3.6L models, the SS models employ a full dual exhaust system, with two catalytic converters to reduce back pressure.

Transmissions 

All Chevrolet Camaro models can be equipped with either a six-speed manual or six-speed automatic transmission. The availability of a six-speed automatic transmission is a first for Chevrolet Camaro.

Standard with the 3.6L engine is the Aisin AY6 six-speed manual. It features lower shift effort and shorter throws for easier shifting and "fun-to-drive" characteristics. A hydraulic clutch and self-adjusting mechanism eliminates the need for adjustments throughout the lifespan of the transmission.

The Hydra-Matic 6L50 six-speed automatic is optional with 3.6L-equipped models. It has an aggressive 4.07:1 first gear ratio that delivers strong launches, but also provides tall overdrive ratios that decrease engine rpm and provide better fuel efficiency. The 6L50 also includes driver shift control, with the driver taking control via paddle shifts located on the steering wheel after selecting the "M" mode on the console-mounted shifter.

Performance Algorithm Shifting (PAS) is included with the 6L50. It lets the electronic transmission controller override the automatic gear selection during high lateral acceleration maneuvers.

On SS models, the new Tremec TR 6060 six-speed manual is paired with the LS3. It is designed to handle the high torque characteristics of the engine, while providing shorter throws, smoother gear synchronization and greater overall shift feel with little or no vibration. Its specs include a solid 290 mm flywheel and single-plate clutch. The final drive ratio for LS3 vehicles is 3.45:1.

The highest-capacity automatic ever in a GM passenger car, the Hydra-Matic 6L80 six-speed automatic, is matched with the L99 engine. Like the 6L50 transmission, it features driver shift control and PAS. The final drive ratio on all automatic-equipped Chevrolet Camaro models is 3.27:1.

Ride & Handling

Fully independent front and rear suspensions are the underpinnings of the 2010 Chevrolet Camaro. The standard independent rear suspension is a first for Chevrolet Camaro and is designed to compete with the best in the world. It's a 4.5-link system that includes a unique, L-shaped upper control arm that attaches to the knuckle at one end and incorporates a ride bushing in the rear.

Based on GM's global rear-drive passenger car architecture, the Chevrolet Camaro sits on a 112.3-inch (2,852 mm) wheelbase, with an overall length of 190.4 inches (4,836 mm). The front track is a wide 63.7 inches (1,618 mm) for all models, while the rear track on LS and LT models is 64.1 inches (1,628 mm) and 63.7 inches (1,618 mm) on SS models.

Two suspension packages are offered: FE2 sport on V-6 models and FE3 performance with the V-8. The front suspension has a dual ball strut system, with a direct-acting stabilizer bar that measures 22.2 x 4 mm on FE2 and 23 x 4.2 mm on FE3. Hollow bars are used for mass savings. The front spring rates for FE2 models are 25 Nm, with wheel travel at 96 mm. FE3 models include a stiffer, 27 Nm spring rate, with wheel travel reduced at 84 mm.

Rear suspension features include high lateral stiffness for handling via three lateral ball joints per side. A sub-frame at the rear is double-isolated to minimize vehicle body motions and dampen road imperfections. The FE2 with a manual transmission includes a spring rate of 53 Nm, with wheel travel at 115 mm, and employs a limited-slip differential. The FE3 rear axle uses a limited slip differential on both manual- and automatic-equipped models; and the rear spring rate is increased to 66 Nm and wheel travel is reduced to 100 mm. Coil-over shock absorbers are used in the rear with a decoupled, hollow stabilizer bar. FE2 includes a 21.7 x 3 mm rear bar, while the FE3's large bar measures 23 x 3 mm.

The axle halfshafts on all V-8 models and manual transmission-equipped V-6 models are 30 mm in diameter on the left side and 40 mm on the right side. This design feature helps reduce the oscillation of torque from side to side and reduces axle hop.

Brakes 

Front brakes for LS and LT models include single-piston calipers with 321 mm x 30 mm rotors. For long life, performance and consistent feel, organic, non-asbestos compounds are used with FE2 brakes. At the rear are vented rear discs measuring 315 mm x 30 mm, with a single-piston aluminum caliper.

The SS front brake package includes Brembo 355 mm x 32 mm vented rotors with four-piston aluminum calipers. Semi-metallic brake linings are used at all four corners on FE3 models for superior fade resistance and pedal feel. The rear brakes are vented Brembos measuring 365 mm x 28 mm, with aluminum four-piston calipers.

Steering 

The 2010 Camaro's precise rack-and-pinion steering gives great driver feedback and cornering confidence. The design includes the rack mounted forward of the front axle centerline that enhances handling and provides a stiffer system, while maintaining a degree of lateral force that helps vehicle stability during turn-in. It also benefits noise and vibration characteristics. The steering ratio is 16.1:1 on all models, with 2.5 turns lock-to-lock. The turning circle diameter for all wheel-and-tire combinations is 37.7 feet (11.5 meters).

Chassis control systems 

All Chevrolet Camaro models include a four-channel StabiliTrak electronic stability control system that incorporates anti-lock braking, traction control and an active braking system to control wheel slip, optimize traction and enhance stability in wet, snow-covered or icy roads.

All SS models have a competitive/sport mode that optimizes the electronic stability control system for competitive driving and track conditions. It provides a less governed level of stability control for expert driving on race tracks. The stability control system engages only in severe oversteer or extreme acceleration in this mode.

New for Chevrolet Camaro SS models with a manual transmission is Performance Launch Control that is enabled in the competitive mode. It is designed to control wheel slip to an optimal level, allowing hard accelerations at launch to achieve maximum grip and vehicle acceleration.

Hydraulic brake assist also is standard on all models. The system activates during emergency braking by detecting the speed and force the driver applies to the brakes. Under certain conditions, the hydraulic brake assist may activate the ABS more quickly and easily than vehicles without the feature.

Wheels and tires 

Standard on LS models are P245/55R18 all season BFGoodrich touring tires mounted on 18 x 7.5-inch steel wheels. Optional wheels include 18 x 7.5-inch and 19 x 8-inch aluminum alloy wheels. On the optional 19-inch wheel, P245/50R19 Pirelli Pzero Nero M+S may be ordered.

For SS models, 20-inch wheels are standard, with tire sizes of 245/45R20 up front and 275/40R20 at the rear. SS models are equipped with Pirelli Pzero summer-only, Z-rated tires. Twenty-one-inch wheels and tires are available as accessories through Chevrolet dealerships.

Chevrolet Stingray Concept (2009)

The Chevrolet Stingray Concept design is influenced by the original Stingray race car, introduced in 1959, but also draws on Corvette heritage cues from other generations. It brings them together in a futuristic shape that seems to be equal parts racecar and space ship.

Chevrolet Camaro SS (2010)

The high-performance Chevrolet Camaro SS is equipped with a powerful 6.2L V-8, with a choice of a six-speed manual or six-speed automatic transmission. Standard, manual transmission-equipped models receive the LS3 engine, estimated at 422 horsepower (315 kW) and 408 lb.-ft. of torque (553 Nm). The LS3 debuted on the 2008 Chevrolet Corvette and uses high-flow cylinder heads based on the Chevrolet Corvette Z06's LS7 engine to enable great low-end torque and high-rpm power. It is paired with a TR6060 six-speed transmission.

A new, L99 V-8 engine is used on automatic transmission-equipped Chevrolet Camaro SS models. It is based on the LS3 and carries all of its high-performance design features, but also includes GM's fuel-saving Active Fuel Management feature. It enables the engine to run on only four cylinders during light-load driving conditions, such as highway cruising, to improve fuel economy. The V-8 is estimated at 400 horsepower (299 kW) and 395 lb.-ft. of torque (535 Nm); and it is matched with a Hydra-Matic 6L80 six-speed transmission. This combination delivers an estimated 23 mpg on the highway.

The Chevrolet Camaro SS receives the FE3 (performance) suspension, including a lower ride height than the base Chevrolet Camaro models. Each is tuned to match the performance capabilities of their respective powertrains, as are their wheel-and-tire combinations.

GM's StabilTrak electronic stability control system is standard and incorporates traction control. The system on Chevrolet Camaro SS models includes Competitive/Sport mode that is adjustable for performance driving, such as on a racetrack; it also includes a Launch Control feature on Chevrolet Camaro SS models with the manual transmission. It enables quicker, more consistent takeoffs during performance driving.

Chevrolet officially announced the 2009 Chevrolet Corvette ZR1 - an American supercar that brings the technology and engineering refinement of carbon-fiber, ceramics and electronics together in a distinctive design.

"Chevrolet's goal with the new Chevrolet Corvette ZR1 is to show what an American supercar can deliver, at a price that trumps exotics that cost two, three or four times as much - and does so with exceptional driveability," said Ed Peper, Chevrolet general manager.

The Chevrolet Corvette ZR1's basic stats:
All-new LS9 supercharged 6.2L V-8 targeted at producing at least 100 horsepower per liter, or 620 horsepower (462 kW), and approximately 595 lb.-ft. of torque (823 Nm)
Six-speed, close-ratio, race-hardened manual transmission
New, high-capacity dual-disc clutch
Higher-capacity and specific-diameter axle half-shafts; enhanced torque tube
Specific suspension tuning provides more than 1g cornering grip
Twenty-spoke 19-inch front and 20-inch rear wheels
Michelin Pilot Sport 2 tires - P285/30ZR19 in front and P335/25ZR20 in the rear - developed specifically for the Chevrolet Corvette ZR1
Standard carbon-ceramic, drilled disc brake rotors - 15.5-inch-diameter (394-mm) in the front and 15-inch-diameter (380-mm) in the rear
Larger brake calipers with substantially increased pad area
Standard Magnetic Selective Ride Control with track-level suspension
Wider, carbon-fiber front fenders with Chevrolet Corvette ZR1-specific dual vents
Carbon-fiber hood with a raised, polycarbonate window - offering a view of the intercooler below it
Carbon-fiber roof panel, roof bow, front fascia splitter and rocker moldings with clear-coated, exposed carbon-fiber weave
ZR1-specific full-width rear spoiler with raised outboard sections
Specific gauge cluster with boost gauge (also displayed on the head-up display) and 220-mph (370 km/h) speedometer readout
Only two options: chrome wheels and a "luxury" package
Curb weight of approximately 3,350 pounds (1,519 kg)


The specialized components of the new Chevrolet Corvette ZR1 work harmoniously to deliver the most powerful and fastest automobile ever produced by General Motors. Performance estimates will be announced closer to vehicle's summer 2008 launch.

"Preliminary testing shows the Chevrolet Corvette ZR1 builds on the highly respected Chevrolet Corvette Z06 in every performance category, from acceleration and braking, to cornering grip and top speed," said Peper. "It all boils down to the power-to-weight ratio and the Chevrolet Corvette ZR1's is exceptional - better than the Porsche 911 GT2, the Ferrari 599 and even the Lamborghini Murcielago LP640. In fact, the Chevrolet Corvette ZR1 is expected to be the first production Corvette to achieve a top speed of at least 200 mph."

Supercharged LS9 engine
The new LS9 6.2L small-block engine is the power plant the supports the Chevrolet Corvette ZR1's performance capability. The enabler of the LS9's performance and refinement is a large, positive-displacement Roots-type supercharger with a new, four-lobe rotor design. It is augmented with an integrated charge cooling system that reduces inlet air temperature for maximum performance.

A sixth-generation supercharger developed by Eaton helps the LS9 make big power and torque at lower rpm and carries it in a wide arc to 6,600 rpm, as it pushes enough air to help the engine maintain power through the upper levels of the rpm band - the area where supercharged performance tends to diminish. Heavy-duty and lightweight reciprocating components enable the engine's confident high-rpm performance.

The LS9 is hand-assembled at GM's Performance Build Center, in Wixom, Mich., and incorporates specialty processes typically seen in racing engines to produce a highly refined and precise product. For example, cast iron cylinder liners are inserted in the aluminum block and are finish-bored and honed with a deck plate installed. The deck plate simulates the pressure and minute dimensional variances applied to the block when the cylinder heads are installed, ensuring a higher degree of accuracy that promotes maximum cylinder head sealing, piston ring fit and overall engine performance.

Transmission and axle
The LS9 engine is backed by a new, stronger six-speed manual transmission and a twin-disc clutch that provide exceptional clamping power, while maintaining an easy clutch effort. Chevrolet Corvette ZR1-specific gearing in the transmission provides a steep first-gear ratio that helps launch the car, and top speed is achieved in sixth gear - a change from the fifth-gear top-speed run-outs in the manual-transmission Corvette and Corvette Z06.

As the term implies, the twin-disc clutch system employs a pair of discs, which spreads out the engine's torque load over a wider area. This enables tremendous clamping power when the clutch is engaged, while also helping to dissipate heat better and extend the life of the clutch.

The twin-disc clutch system also contributes to the Chevrolet Corvette ZR1's exceptional driving quality, with smooth and easy shifting. The twin-disc system's design enables a 25-percent reduction in inertia, thanks to smaller, 260-mm plates, corresponding to a pedal effort that is similar to the Corvette Z06's 290-mm single-disc system.

The rear axle also is stronger in the Chevrolet Corvette ZR1 and features asymmetrical axle-shaft diameters that were developed after careful testing to provide optimal torque management. The axles are also mounted on a more horizontal plane that correlates with the wider width of the rear wheels and tires.

Ride and handling
The Chevrolet Corvette ZR1 is built on the same aluminum-intensive chassis as the Corvette Z06 and features similar independent SLA front and rear suspensions, with aluminum upper and lower control arms. Where the Chevrolet Corvette ZR1 differs is the suspension tuning, which was optimized for the car's steamroller-wide front and rear tires.

Magnetic Selective Ride Control is standard and tuned specifically for the Chevrolet Corvette ZR1. The system's ability to deliver a compliant ride with nearly instantaneous damping adjustments enabled engineers to develop a surprisingly supple ride quality in a supercar that still delivers cornering grip of more than 1g.

From a high-performance perspective, Magnetic Selective Ride Control helps the rear axle remain planted during launch for smooth, hop-free acceleration. It also helps suppress axle movement when cornering on broken or uneven pavement.

Brakes, wheels and tires
Commensurate with the Chevrolet Corvette ZR1's engine output is the braking system, which is headlined by carbon-ceramic brake rotors. Found on only a few exotics and more expensive supercars, carbon-ceramic brake rotors are made of a carbon-fiber-reinforced ceramic silicon carbide material . Their advantage comes in low mass and resistance to wear and heat. In fact, the rotors should never show any corrosion or require replacement for the life of the vehicle, when used in normal driving.

The vented and cross-drilled rotors on the Chevrolet Corvette ZR1 measure 15.5 inches (394 mm) in diameter in the front and 15 inches (380 mm) in diameter in the rear - making them among the largest carbon-ceramic rotors available on any production vehicle.

Clamping down on the high-tech rotors are six-piston front calipers and four-piston rear calipers, each painted a Chevrolet Corvette ZR1-exclusive blue. The front pads are equivalent in size to the largest on any production car with a single-pad design - double that of the Corvette Z06's 70-sq.-cm. front pads.

The brakes are visible through the Chevrolet Corvette ZR1's exclusive wheels: 20-spoke alloy rims that measure 19 inches in diameter in the front and 20 inches in the rear. They come standard with a bright, Sterling Silver paint finish and chrome versions are optional. The wheels are wrapped in Michelin Pilot Sport 2 tires developed specifically for the Chevrolet Corvette ZR1, measuring P285/30ZR19 in front and P335/25ZR20 in the rear.

Exclusive exterior
The Chevrolet Corvette ZR1 is instantly recognizable, with perhaps the most identifiable feature a raised, all-carbon-fiber hood that incorporates a clear, polycarbonate window. The window provides a view of the top of the engine's intercooler, with the legend "LS9 SUPERCHARGED" embossed on the left and right sides, and an engine cover with the Corvette crossed flags logo debossed at the front.

The underside of the hood has an exposed carbon-fiber-weave. Exposed carbon-fiber is used on the roof, roof bow, rocker molding and front splitter. These exterior components are protected by a specially developed glossy, UV-resistant clear coat that resists yellowing and wear.

Widened, carbon-fiber front fenders with specific, dual lower vents, and a full-width, body-color rear spoiler incorporating the center high-mounted stop lamp, are also unique to the Chevrolet Corvette ZR1. All of the exterior features of the car were developed to enhance high-speed stability and driver control.

Interior details
The Chevrolet Corvette ZR1's interior builds on the brand's dual-cockpit heritage, with high-quality materials, craftsmanship and functionality that support the premium-quality experience promised by the car's performance. The Chevrolet Corvette ZR1's cabin differs from the Chevrolet Corvette and Corvette Z06 with the following:
ZR1-logo sill plates
ZR1-logo headrest embroidery
Specific gauge cluster with "ZR1" logo on the tachometer and a 220-mph (370 km/h) readout on the speedometer
Boost gauge added to the instrument cluster and Head-Up Display

The "base" Chevrolet Corvette ZR1 (RPO 1LZ) comes with accoutrements based on the Chevrolet Corvette Z06, including lightweight seats and lightweight content. The uplevel interior package includes unique, power-adjustable and leather-trimmed sport seats (embroidered with the ZR1 logo); custom, leather-wrapped interior available in four colors; navigation system, Bluetooth connectivity and more.

By the numbers
In addition to the exterior cues and powertrain, Chevrolet Corvette ZR1 models will be distinguished from other Corvette models by their VIN. Each will carry a unique, identifying VIN digit, as well as a sequential build number. This makes it easy to determine the build number of a specific car - information treasured by enthusiasts and collectors. For example, a Chevrolet Corvette ZR1 with a VIN ending in "0150" would indicate it is the 150 th Chevrolet Corvette ZR1 built for the model year.

Chevrolet Camaro (2010)

Chevrolet introduced the production 2010 Chevrolet Camaro. It is a heritage-inspired sports car for the 21 st century, combining great looks and performance; advanced technology and surprising efficiency - including 26-mpg estimated highway fuel economy. Sales begin in the first quarter of 2009.
Built on GM's new, global rear-wheel-drive architecture, the Chevrolet Camaro is offered in V-6-powered LS and LT models, as well as the V-8-powered SS. All models and powertrain combinations include fuel-saving six-speed transmissions.

Design
With a design that is very faithful to the original concept, the 2010 Chevrolet Camaro is a 21 st century sports car that acknowledges its heritage. A long front dash-to-axle and short rear deck give the Chevrolet Camaro classic proportions, while a sleek windshield profile, wheels pushed to the corners and muscular fender forms are modern elements that reinforce its advanced engineering - and give the car a decidedly aggressive stance.
Elements such as a forward-V shape at the front of the car and "gills" in the rear quarter panels are distinctly Chevrolet Camaro cues, as are the broad rear fender "shoulders." Those elements make the new Chevrolet Camaro instantly recognizable, but their execution is smoothly integrated into the contemporary exterior form. A family of large, 18-, 19- and 20-inch wheels also contributes to the Chevrolet Camaro's modern appearance.


"The new Chevrolet Camaro is just that - new," said Ed Welburn, vice president of GM Global Design. "We acknowledge the nameplate's strong heritage in the design, but recognize that keeping this modern sports car relevant meant more than simply honoring a classic car. The line forms, stance and overall execution are consistent with other new Chevrolets."
A well-executed balance of heritage, modern design and attention to detail also characterizes the Chevrolet Camaro's interior. A pair of deeply recessed instrument binnacles that feature round gauges in square housings is a nod to classic Camaros, while an available ambient light package offers advanced LED light pipe technology to give the cabin a distinctive and inviting glow. Cloth upholstery is standard; heated leather-appointed seats are available.

Details such as large, chrome-trimmed controls, low-gloss surfaces and premium fabric or acrylic appliqués convey a richness that is unprecedented in previous Chevrolet Camaro models - and challenge its contemporary competitors. More great detail is evidenced in the available center-console gauge cluster, which takes its cue from a similar option on 1969 Chevrolet Camaro. It displays oil temperature, oil pressure, state-of-battery and transmission fluid temperature, all highlighted with modern LED backlighting.

Powertrains
An advanced, efficient 3.6L direct-injected V-6 with variable valve timing is standard on LS and LT models. Direct injection technology helps the engine deliver more power through increased efficiency, while maintaining fuel economy and lowering emissions. That means less fuel is consumed and lower emissions generated - including a 25-percent drop in cold-start hydrocarbon emissions.

The Chevrolet Camaro's 3.6L engine also employs variable valve timing to optimize performance and fuel economy across the rpm range. It is rated at an estimated 300 horsepower (224 kW) and 273 lb.-ft. of torque (370 Nm). A six-speed manual transmission is standard with the 3.6L engine; a Hydra-Matic 6L50 electronically controlled six-speed automatic, with TAPshift control, is available.

The high-performance Chevrolet Camaro SS is equipped with a powerful 6.2L V-8, with a choice of a six-speed manual or six-speed automatic transmission. Standard, manual transmission-equipped models receive the LS3 engine, estimated at 422 horsepower (315 kW) and 408 lb.-ft. of torque (553 Nm). The LS3 debuted on the 2008 Corvette and uses high-flow cylinder heads based on the Corvette Z06's LS7 engine to enable great low-end torque and high-rpm power. It is paired with a TR6060 six-speed transmission.

A new, L99 V-8 engine is used on automatic transmission-equipped SS models. It is based on the LS3 and carries all of its high-performance design features, but also includes GM's fuel-saving Active Fuel Management feature. It enables the engine to run on only four cylinders during light-load driving conditions, such as highway cruising, to improve fuel economy. The V-8 is estimated at 400 horsepower (299 kW) and 395 lb.-ft. of torque (535 Nm); and it is matched with a Hydra-Matic 6L80 six-speed transmission. This combination delivers an estimated 23 mpg on the highway.

Body structure and chassis
The 2010 Chevrolet Camaro is built on GM's global rear-wheel-drive architecture, with a strong body structure that enhances safety, quietness and handling. World-class build quality and attention to detail are enabled by features including one-piece body side stampings and very precise tolerances between body panels.

Front and rear independent suspensions are mounted to the rigid chassis, including a multi-link strut arrangement in the front with a direct-acting stabilizer bar and a double ball-joint configuration; and a unique, 4.5-link rear suspension that is double-isolated from the chassis for smoother, quieter driving experience.

Chevrolet Camaro offers two suspensions. LS and LT models receive an FE2 (sport) suspension, while the SS receives the FE3 (performance) suspension, including a lower ride height. Each is tuned to match the performance capabilities of their respective powertrains, as are their wheel-and-tire combinations.

A variable-rate rack-and-pinion power steering system mounts the rack forward of the front axle, for more direct action, an enhanced feeling of driver feedback and better weight balance.

Brakes and chassis control
Four-wheel disc brakes with ABS are standard on all models. LS and LT models receive single-piston calipers all around, with mass-reducing aluminum rear calipers. SS models have larger rotors that are acted upon by four-piston, aluminum Brembo calipers at all four corners. They are designed to stand up to the severe use encountered on road-race tracks, delivering excellent feedback and pedal feel, as well as fade-resistant performance during racing.

GM's StabilTrak electronic stability control system is standard and incorporates traction control. The system on SS models includes Competitive/Sport mode that is adjustable for performance driving, such as on a racetrack; it also includes a Launch Control feature on SS models with the manual transmission. It enables quicker, more consistent takeoffs during performance driving.

Safety
Designed to protect occupants before, during and after a crash, the Chevrolet Camaro offers a comprehensive system of safety features - starting with a robust body structure and integral safety cage around the passenger compartment. High-strength steel and ultra high-strength steel are used in key areas throughout the structure.

Safety technologies integrated in the Chevrolet Camaro include:
Driver and front-passenger dual-stage air bags
Driver and front-passenger seat-mounted thorax side-impact air bags
Head curtain side-impact air bags for front and rear seat occupants
Front seat safety belt load limiters and pre-tensioners

The front passenger protection system senses children and small-stature adults and suppresses air bag deployment when appropriate.

Chevrolet Corvette Z06

The new Z06 arrived as a 2006 model in the third quarter of 2005. It has a 7.0 L (7,008 cc/427.6 in³) version of the small block engine codenamed LS7. Officially certified output is 505 hp (377 kW). Dave Hill, the chief engineer for the C6 Corvette, says that it is a much further departure from the standard Corvettes and more like the C6-R that GM is building for the American Le Mans Series. Its performance is similar to the Ford GT and the Dodge Viper SRT-10. Official performance figures indicate that the Z06 can reach 60 mph in just 3.5 seconds from a standing start in first gear. In the summer of 2005, GM and Corvette Racing driver Jan Magnussen brought the new Z06 to the Nürburgring in Germany. Magnussen drove the Z06 to a time of 7:42.99; few production cars have posted faster times. Car and Driver tested the Z06 in their December 2005 issue, recording a 0 to 60mph time of 3.4 seconds and a standing quarter mile of 11.9 seconds at 125 mph.

In addition to the larger engine, the C6 Z06 has a dry sump oiling system, ensuring proper engine lubrication during periods of high (lateral) acceleration and allowing the engine to be mounted low inside the chassis. Connecting rods made out of titanium further lighten the reciprocating mass of the engine while being stronger than the steel rods they replace. Altogether, the Z06 model not only produces more power, it revs higher than any other Chevrolet LS-motor.

In a radical departure from anything Chevrolet has ever done before, the primary structural element of the C6 Z06 is aluminum instead of steel as on the non-Z06 cars. The hydroformed aluminum frame remains dimensionally identical to its steel brethren but is significantly lighter. The front fenders are made of carbon fiber to reduce weight, while wider rear fenders allow for the wider tires necessary to deal with the engine's increased power. The Z06 officially weighs 3132 lb (1421 kg), giving it a power to weight ratio of 6.2 lb/hp (3.8 kg/kW or 361 bhp per tonne). The C6 Corvette Z06 is the first 500+ hp production car to avoid the US government Gas Guzzler tax.

On October 31, 2005, the application of magnesium AE44 alloy in the engine cradle (the world's first magnesium chassis component) was bestowed an Honorable Mention in the Automotive News PACE™ (Premier Automotive Suppliers' Contributions to Excellence) Awards competition. This is the first award granted to the C6 Z06 Corvette. The suppliers receiving the award were Norsk Hydro Magnesium and Meridian Technologies, Inc.

Taken as a whole, the C6 Z06 is more similar to its race-going variant, the C6-R, than the C5 Z06 was to the C5-R. The number of production automobiles from all marques across the globe featuring more than 500 hp (370 kW) is small indeed. With an official list price of US$70,000 per unit, it will likely be the only such vehicle in existence with a price tag under US$85,000. Proof that the car was priced aggressively, dealers in the United States have successfully marked the Z06 up to anywhere from $80,000 to $100,000, due to strong sales and low inventories [in 2006].

The Z06 was the official pace car for both the 2006 Daytona 500 and the Indianapolis 500 race, and notably so since it was the first pace car faster than cars it was pacing. The special Pace Car edition Z06 was unveiled at the Los Angeles Auto Show in January. It was also awarded to St. Louis Cardinals shortstop David Eckstein as his prize for being the 2006 World Series MVP, although Eckstein does not know how to drive a stick. The 2007 Z06 was also one of Automobile Magazine's "Automobile All-Stars" for 2007.
