Lexus LFA (2011)

Download Lexus LFA Wallpapers(45)

The new Lexus LFA marks an important moment in both the history of Lexus and the development of the supercar. A true "clean-sheet" design, the Lexus LFA was created by a small, passionate and dedicated team of engineers whose achievement has been to push the boundaries of technologies materials and engineering at every stage to produce a car like no other to have carried the Lexus badge.

Constructed using advanced carbon fibre technology, the rear-wheel drive Lexus LFA is powered by a bespoke, high-revving 552bhp 4.8-litre naturally aspirated V10 engine, matched to a rear-mounted six-speed sequential automatic transmission, giving 200mph-plus performance.

In the words of Chief Engineer Haruhiko Tanahashi: "The Lexus LFA is a thoroughbred supercar, a machine engineered to achieve a single goal - to deliver a supreme driving experience. Over the past decade we have pushed every boundary in pursuit of this goal and I believe we have created the most driver-orientated car we possibly could."

CARBON FIBRE CONSTRUCTION

Keeping the car's weight to an absolute minimum was one of the defining elements in the development of the Lexus LFA and this led to the decision to switch from using aluminium for the car's construction to advanced Carbon Fibre Reinforced Plastic (CFRP) for the chassis and bodywork.

Moreover, Lexus decided the CFRP structure should be built in-house rather than by a third-party supplier. In doing so, it drew on Toyota Motor Corporation's heritage in textile weaving technology to push the boundaries of its technical abilities, developing new carbon fibre looms and a laser system for monitoring the integrity of the material.

At four times the strength of aluminium, CFRP gives the Lexus LFA an exceptionally stiff and strong structure, and also delivers major weight advantages, saving around 100kg on an equivalent aluminium body. CFRP accounts for 65 per cent of the body-in-white, with aluminium alloy used for the remaining 35 per cent.

Unlike the few other vehicles on the market that use CFRP construction, the Lexus LFA uses the same advanced resin technology favoured by cutting-edge aerospace programmes for its unmatched weight and strength properties.

ENGINE

The heart of the Lexus LFA is a bespoke, naturally aspirated V10 engine that sets new standards for compact dimensions, lightweight architecture and scintillating performance. From the outset it was determined the engine should have a 4,805cc capacity, develop 552bhp and rev to a wailing 9,000rpm red line. A 72-degree angle between the cylinder heads is ideal for achieving balance in the engine for exceptionally smooth running, while providing individual, electronically controlled throttle bodies for each cylinder gives excellent throttle response.

Using a dry sump lubrication system allows the block to be positioned deep in the engine bay, lowering the car's centre of gravity and moment of inertia, and enabling the engine to handle sustained, high-speed cornering.

The V10 produces 480Nm of torque at 6,800rpm, 90 per cent of which is available from 3,700rpm all the way to the 9,000rpm red line, thanks to Dual VVT-i technology, equal length exhaust manifolds and high-volume, 12-hole fuel injectors. This gives searing in-hear acceleration at all engine speeds and in any gear: nought to 62mph takes just 3.7 seconds and maximum speed is 202mph.

With a kerb weight of 1,480kg, the Lexus LFA has a power to weight ratio of 373bhp per tonne, while specific output of 115bhp per litre is among the highest of any current supercar, aided by a high, 12:1 compression ratio, low friction internals and optimised intake and exhaust flow.

In spite of its potency, the V10 is an object lesson in compact and lightweight packaging, being about the same size as a regular V8 engine and weighing about as much as conventional V6. It is also as reliable and refined as any other Lexus power plan and exceeds Euro 5 emissions standards.

The engine was developed in conjunction with Yamaha through the established collaborative partnership between Toyota Motor Corporation and the Japanese specialist engineering company.

TRANSMISSION

The formidable performance of the V10 is managed through an equally advanced transmission, a purpose-designed six-speed Automated Sequential Gearbox (ASG) that drives the rear wheels via a limited slip differential. To help achieve the optimum 48:52 front-to-rear weight distribution, it is contained in a transaxle mounted over the rear axle.

The ASG is operated by paddle shifts mounted on the steering column and is engineered for exceptionally fast shifts: an upshift can be effected in just 0.2 seconds.

The system has four driving modes: Auto, Sport, Normal and Wet, activated by a selector dial on the dashboard. Each mode has a specific gearshift programme, and engine and brake control logic systems to let the driver tailor the car's performance to suit driving conditions.

SOUND

The Lexus LFA's acoustics, induction system and exhaust notes have been specially tuned to deliver an awesome "soundtrack" that expresses the car's extreme performance, both outside and inside the cabin. Referred to by the acoustic team as "Octave Harmony", it is inspired by the sound of a Formula 1 engine at full revs and is unlike that of any other road car, with different harmonic qualities created as the engine moves up towards its maximum 9,000rpm.

BRAKING

The Lexus LFA has one of the most advanced and powerful braking systems fitted to any production car, appropriate to meet the demands of its 200mph-plus performance capabilities.

The brake discs are made of Carbon Ceramic Material (CCM), which as well as being lighter than steel, gives fade-free performance in all conditions. The front discs are 390mm in diameter and 34mm thick, gripped by six-piston aluminium callipers; the rear discs measure 306mm across, are 28mm thick and are fitted with four-pot callipers. All use high-friction micron pads, manufactured exclusively for use with CCM brakes.

SUSPENSION, WHEELS AND TYRES

The track-tuned suspension is the result of intensive development work carried out by Lexus at the Nürburgring's Nordschleife circuit to give the best possible balance between control and comfort.

The bespoke wishbone front/multilink rear design makes extensive use of aluminium alloy for high strength and low weight, and the aluminium monotube dampers are the same as those Lexus used for its LFA race car in the Nurburgring 24-hour race.

The 20-inch forged aluminium BBS wheels are shod with asymmetric Bridgestone tyres: 265/35ZR20 at the front and 305/20ZR20 at the rear.

AERODYNAMICS

The Lexus LFA boasts class-leading aerodynamics to achieve drivetrain cooling and superb high-speed handling and stability. Extensive wind tunnel testing helped produce a wind-cheating profile with a drag coefficient of 0.31, a remarkable achievement given the degree of downforce the car creates at high speed.

Airflow is precisely controlled over, under and around the car. A carbon fibre rear diffuser and flat underbody generate significant downforce, with an active rear wing, complete with a gurney flap on the leading edge, boosting the level further still.

STEERING

The race-tuned steering gives outstanding response and feedback to create a perfect dynamic link between car and driver. The constant-rate rack and pinion system uses an innovative column-assist Electric Power Steering System that does not sap engine performance.

The large-diameter column shaft is mounted directly on the central chassis structure, giving the steering layout exceptional rigidity. The carbon fibre steering wheel has a flat bottom section and houses the engine starter button and instrument information selector switch. It can be adjusted for reach and rake.

EXTERIOR DESIGN

Dictated by its front-mid engine layout, long wheelbase and short overhangs, sophisticated aerodynamics and low-slung cabin, the Lexus LFA's lines flow from roof to sill in a seamless convex to concave line. As well as its low weight and high strength, carbon fibre reinforced plastic (CFRP) also gave the designers more freedom to create shapes, curves and edges that would have been impossible with metal.

The styling remains true, however, to the principles of L-finesse, the design rationale behind all current Lexus models. Form follows function, as witnessed n the numerous air intakes and aerodynamic details, and even in the design of the door mirrors, shaped to channel air over the car's shoulders into the rear intakes.

INTERIOR DESIGN

The low-slung cabin is divided into three zones: the mechanical zone, which includes the skeleton of the car's construction; the human zone, with two seats placed right at the centre of the car; and the driving zone, with high-tech instrumentation that brings driver and machine together.

The cabin is hand-built, with driver-focused ergonomics. The seats, upholstered in fine leather and Alcantara, provide the high level of back and side support needed in a car capable of 200mph-plus performance. The trim echoes the advanced materials used in the Lexus LFA's construction, with exposed areas of both matt and gloss carbon fibre. Trim details are finished in brushed metal and the floor-hinged brake and throttle pedals are made of forged aluminium. As with the exterior finish, owners can choose different interior colours and details to suit personal taste.

INSTRUMENTATION

The compact, hooded instrument panel combines an LCD display panel with a colour Thin Film Transistor (TFT) and a motor-drive movable ring. It features a single circular dial with a central tachometer with an LCD needle. When engine speed exceeds 9,000rpm, the display area turns red to prime the driver for an up-shift. It can also be programmed to turn yellow or green when the revs reach a user-selected range. The dial also houses a digital speedometer and gear indicator, transmission mode, vehicle control data and trip information displays.

An information selector switch on the left side of the steering wheel lets the driver toggle through a series of functions, including customising the data display, adjusting cabin illumination and operating a track-ready stopwatch system.

When the car is started, an instrument display sequence is triggered, creating a sense of occasion, culminating in the four digital dials showing oil and water temperatures, fuel level and oil pressure radiating out from the centre of the rev counter to take up their positions on either side of the central dial.

SAFETY

Passive and active safety provisions are in line with the Lexus LFA's exceptional performance. The central carbon fibre reinforced plastic central structure is extremely strong and provides excellent impact protection. Crash boxes are fitted front and rear that are designed to deform in a controlled fashion in the event of an impact. That at the front is made of CFRP; that at the rear from extruded aluminium. Side impact protection includes strong and rigid carbon fibre side members and door structures comprising an aluminium inner panel and a Glass fibre reinforced Sheet Moulding Compound (G-SMC) outer skin.

The Lexus LFA is equipped with Lexus's Vehicle Dynamic Integrated Management (VDIM) system, which co-ordinates the smooth operation of the ABS, vehicle stability and traction control systems as the vehicle approaches its performance limits, based on critical data on brake operation, yaw and roll rates, individual wheel speed and longitudinal, lateral and vertical acceleration

Passive safety features include two-stage adaptive front airbags and seatbelt airbags for driver and passenger and a driver's knee airbag.

MANUFACTURING AND SALES

The Lexus LFA programme was launched in 2000 as a straightforward R&D project, but gained impetus with the appointment of Haruhiko Tanahashi to lead a dedicated team of engineers, committed to a bespoke Lexus development programme. The first Lexus LFA prototype was completed in 2003 and a design study made its public debut at the 2005 Detroit motor show. In 2008 and 2009 the Lexus LFA was entered in the Nurburgring 24-hour race, the intention being to push the car hard under testing conditions prior to its official launch as a production-ready model at the 2009 Tokyo motor show.

The Lexus LFA will be hand-assembled at the Motomachi plant in Toyota City. Only 500 examples will be built, at a maximum rate of 20 per month to ensure the finest build quality and attention to detail. Each V10 engine will be assembled by a single engineer, and will bear his signature as testament to each Lexus LFA's bespoke status.

The UK launch price for the Lexus LFA is €368,000 (approximately £336,000). Owners can choose from an extensive range of options to personalise their car, including 30 different paint finishes. Certain items of standard equipment can also be removed, such as the audio system, to reduce the car's weight.

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.

Toyota FT-86 Concept (2009)

The Toyota FT-86 Concept is 4,160mm long, 1,760mm wide, and 1,260mm high with a wheelbase of 2,570mm, giving it a compact feeling that is easy for the driver to handle while able to accommodate four occupants. In addition to being light and having a low center of gravity, the Toyota FT-86 Concept boasts the handling of a racing car as well as a 6-speed manual transmission and ADVICS brakes.

The stylish concept captures the heart with the "functional utility" of its highly-refined body. It is the creation of Toyota Europe Design Development known as ED2, which has established body lines that take into consideration a low center of gravity and aerodynamics. The interior is distinctive, featuring an instrument panel with a gray and white base, gauges with red neon lights and digital displays, and a navigation system. In addition, a zipper that evokes an image of interior lapping with minimal covering of a highly-refined body presents a striking display.

It is necessary to create a vehicle in which the driver plays the main role in order to have as many people as possible experience the joy of driving.
The Toyota FT-86 Concept is neither an electric vehicle nor a hybrid vehicle, but is a sports model with a gasoline engine developed to convey the essential appeal of automobiles in a new era. It is a must-see concept car that expresses TMC's desire to once again create a Toyota sports car.

A Small FR Sports Concept Vehicle that Combines Environmental Performance and the Joy of Driving
TMC seeks to develop the ultimate earth-conscious environmentally-considerate vehicle with a focus on hybrid technologies without losing sight of the appeal of cars themselves or the joy of driving.

Over the past several years, the need has been rising for motor vehicles that take into consideration global warming and other environmental issues, while there has also been concern that there have been too few new sports cars that make the heart beat faster and that the time is right for a new generation of sports cars. In response to these needs, TMC has developed the Toyota FT-86 Concept, a sports car equipped with a 2,000cc, horizontally opposed, four-cylinder, naturally-aspirated gasoline engine that evokes the joy of driving a car and the pleasure of vehicle ownership.

As the name "Future Toyota 86 Concept" implies, the Toyota FT-86 Concept, which will be exhibited at the 2009 Tokyo Motor Show, is a new 86 Toyota with a flash red finish. It is a compact, rear-wheel drive sports concept car that embodies speed and the excitement of driving that give cars their appeal as well as environmental performance.
