The Mazda stand at the 2009 Geneva Motor Show is greener than ever before. One way Mazda achieved this is to develop unique idle-stop technology that shuts down the engine when stopped in traffic jams and similar situations as a way to reduce fuel consumption.

The Mazda 3 will be powered by the MZR 2.0L DISI engine with green idle-stop technology - Mazda's unique i-stop system. Developed solely by Mazda, it is the world's only idle-stop system that restarts the engine using the remaining energy in the pistons (with a quick help of the starter motor) by injecting fuel directly into the cylinder and igniting it to force the piston down. The benefit of combining a DISI engine with i-stop (originally called SISS: Smart Idle Stop System) is that the system restarts the engine about twice as fast, and quieter, than conventional idle-stop systems.

Combining these two Mazda proprietary technologies and further measures like aerodynamic modifications, help the new Mazda 3 achieve approximately 14 percent lower fuel consumption (combined) than the previous Mazda 3.

When the driver stops the vehicle (red light, traffic jam) the engine stops automatically and sets itself to be ready for a prompt restart. As soon as the driver presses the clutch, the engine initiates the restart procedure automatically. This is a totally neutral operation for the driver.

Mazda 3 i-stop Green Technology
When stopped at a traffic light or in a traffic jam, shutting off the idling engine can reduce fuel consumption by approximately 5 percent according to European city driving-mode tests. However, the drawback with conventional idle-stop systems is that they rely solely on the use of an electric motor to restart the engine. As such, they require a relatively long amount of time to achieve combustion in the engine when it restarts. In real-world driving, this means a lag between the moment the accelerator pedal is pressed down and the car begins to move, as well as vibration and noise.

The i-stop system for the new Mazda 3 leverages the DISI engine's direct-injection potential for improving fuel economy, restarting the engine quickly and quietly by injecting fuel directly into the cylinder and igniting it to force the piston down and set the crank in motion. The engine is controlled with precision to make this happen:

Special engine requirements
In order to use combustion energy from the initial stage of restarting the engine, and to start the engine quickly, the following three conditions must be satisfied while the engine is stopped. (1) The engine must be able to inject fuel directly into the combustion chamber and ignite it; (2) an adequate amount of clean air must exist in the combustion chamber of the cylinder where the fuel is to be ignited; and (3) the computer control system must be able to determine which cylinder to fire immediately after starting the engine. The i-stop system, therefore, must use a direct-injection engine that can deliver fuel to the combustion chamber at high pressure, and that can easily ignite that fuel. Mazda's MZR 2.0-litre DISI petrol is the ideal engine to achieve this.

Controlling piston position
The pistons are stopped in the appropriate position when the engine is stopped, an adequate amount of air is held within the combustion chamber, and the combustion chamber is properly scavenged to reduce the amount of unburned petrol. To this end, piston position is controlled by applying current to the engine's generator while the engine is being shut down. In doing so, it operates much like an electric motor, while using the signal from the crank angle sensor that monitors piston position as control feedback to stop the piston in the appointed position within its expansion stroke.

Special valve and crankshaft balance control
To scavenge the combustion chamber, the new Mazda 3 i-stop system momentarily opens the throttle valve slightly during the shut down process. (The throttle valve is normally closed when shutting off the engine.) Regular crank angle sensors are only able to determine forward rotation, which leaves them unable to monitor reverse rotation or to determine the correct piston position. Mazda's i-stop employs a crank angle sensor that is able to monitor crank rotation in both directions, enabling it to accurately determine the correct piston position. To maintain the proper crankshaft balance when the engine is stopped, it is rotated slightly in the reverse direction.

Faster restart + lower fuel consumption
These measures make it possible to properly inject fuel when the engine is restarted and control ignition advance, thereby allowing combustion energy to be used while the engine is stopped and to restart the engine in 0.35 seconds, roughly half the time required by conventional idle-stop systems. While Mazda's new i-stop system employs combustion energy to restart the engine, it is assisted by the starter for only the first few turns of the crank. This achieves the optimum balance between maximizing fuel savings while minimizing the amount of time required to restart the engine. As a result, it allows i-stop to reduce fuel consumption beyond what would be possible using combustion energy alone to restart the engine.

Driver support communication system
On the new Mazda 3 powered by the MZR 2.0 DISI engine, the i-stop system supports the driver by allowing visual confirmation of engine operation in relation to driving style. There is an i-stop on/off switch on the dashboard, and the driver cluster contains a light that displays "i-stop" when the system shuts down the engine in front traffic lights, for instance. When deactivated, an amber light shows that the i-stop system is not on.

Ensuring reliable operation
The new Mazda 3 i-stop system (only available with the MZR 2.0-litre DISI petrol) is equipped with an auxiliary battery that powers the system in the event that the main battery isn't properly charged or some similar problem occurs. This added control measure ensures that the driver can use the system naturally, without giving it a second thought. In addition, the system does not shut off the engine if the car is stopped on a road with an extremely steep grade, (greater than 14 percent incline).

Daihatsu Materia mini-MPV went on sale in the UK in July 2008 with prices starting from £10,995 on-the-road offering outstanding interior space and distinctive styling.

In fact, the boxy yet wide and squat design theme with flared wheelarches and minimum overhangs has created a cult-following in Japan - and now the United States - with several manufacturers struggling to keep up with consumer demand.

Key competitors in the UK and Europe are the similar-sized but move conservatively-styled Renault Modus and Vauxhall/Opel Meriva. All are compact and versatile with a high-command driving position that especially appeals to women.

However, the Materia's owners are expected to include style-conscious young families seeking a distinctive yet practical design plus older couples who appreciate the Materia's low running costs, manoeuvrability and easy access thanks to wide-opening and deep doors.

The Daihatsu Materia specification is exceptionally high and includes: power steering, ABS with EBD, driver, passenger and side airbags, air-conditioning, remote central-locking, height-adjustable driver's seat, sliding and reclining split rear seat, alloy, wheels, rear privacy glass, front fog lamps and a radio/CD player with six speakers.

Powered by a lively 103.3 PS 1.5 litre petrol engine, the Daihatsu Materia is both economical at 46.3 mpg on the Extra Urban Cycle (manual) and 45.6 mpg (automatic) and offers a 100-plus mph top speed. This leaves plenty in reserve for comfortable long-distance motorway travel.

Daihatsu Materia Design Concept
The Materia's funky yet practical shape maximises interior space and was designed to be both distinctive and spirited. It is sold as both a Toyota and Daihatsu in Japan.

Its exceptionally short overhangs and flared wheelarches give a ground-hugging stance, while the squared-off passenger compartment promises - and delivers - outstanding space.

The front design is quite imposing with a chunky, deep bonnet and chiselled look to the headlamps and narrow but wide grille, cut into the deep bumper.

The Materia's rear also emphasises its width, strength and stability, emphasised by a swooping, low-mounted panel that connects the narrow rear lamps which gently curve over each rear wheelarch.

From the side, large 15 ins diameter spoked alloy wheels - linked by deep side skirts - further reinforce the message of stability. The generous 185/55 tyres combined with a wide track 'fill' the wheel openings.

Size Comparisons
The Daihatsu Materia's spacious cabin features both a generous interior width and length clothed in a compact body with excellent manoeuvrability thanks to good visibility and a tight 9.8 metre turning circle (kerb-to-kerb).

Its overall length of 3,800 mm is between the Renault Modus (3,792 mm) and Vauxhall Meriva (4,042 mm). The Daihatsu's width of 1,690 mm is almost identical to the 1,695 mm of the Renault and 1,694 mm of the Vauxhall.

The Materia's 1,635 mm height compares with the1,589 mm of the Modus and 1,624 mm of the Meriva, while the Daihatsu's wheelbase of 2,540 mm exceeds the 2,482 mm of the Renault but is slightly shorter than the Vauxhall's 2,630 mm.

Its 1,420 mm interior width far exceeds the Renault Modus which can only offer 1,280 mm. This, combined with an interior length of 1,950 mm (Vauxhall Meriva 1,825 mm) offers outstanding useable space.

The Daihatsu Materia offers 619 litres of load space with the rear seat folded and either 294 or 181 litres with the rear seat upright (VDA) depending on whether the seat is slid forward or backwards.

Versatile, Funky-Looking Interior
The Materia's stylish and versatile interior includes a rear seat that has a rake-adjustable backrest which can also be fully reclined to form a bed, joining the equally fully-reclining front seats.

The rear seat also features a 60/40 split plus fore and aft slide adjustment of 160 mm. This allows a fully-flexible rear legroom/load space compromise. The rear tailgate opening is flush with the load floor for easy loading and unloading.

A compartment under the rear floor allows the storage of various items such as tools, while a deep bottle holder is also included in the side of the luggage compartment. Interior bottle holders can be found in both front and rear doors plus four in the centre console.

Meanwhile, the interior design itself is both funky and interesting with, for example, blue illumination of the front door armrests and circular front door speakers.

The centrally-mounted acrylic instrument panel creates a futuristic, three-dimensional look boosted by a swooping, stadium-shaped arc to the entire fascia.

Other distinctive features include a glossy black finish to the flush-fitting audio unit and side air-conditioning vents for a high-quality look.

Lively, Frugal, Advanced Petrol Engine
The new Daihatsu Materia features a lively and frugal 1.5 litre petrol engine offered with the choice of either five-speed manual of four-speed automatic transmission.

The engine itself is highly advanced and is similar to that fitted to the Daihatsu Terios compact SUV and can also be seen in 1.3 litre form in the Sirion supermini.

Featuring Dynamic Variable Valve Timing (DVVT) which enhances low-speed pulling power and high-rev response, the twin overhead camshaft unit is compact and light, with an alloy head and block.

Power is 103.3 PS at 6,000 rpm with torque of either 97.4 lb ft at 4,400 rpm for the Daihatsu Materia manual or 101.8 lb ft in the automatic. The engine has a 10.0:1 compression ratio and features a bore and stroke of 72 x 91.8 mm.

It also features durable chains for its camshaft drive which require no maintenance and cannot snap like belt systems.

The five-speed manual gearbox and four-speed automatic both have carefully chosen ratios that provide sprightly acceleration from standstill yet relaxed cruising.

To further aid refinement, various sound-insulation measures enhance noise-suppression. These include asphalt sheets for the passenger floor plus fascia, engine compartment and body frame insulators. All four doors have double seals for a quality closing experience and further refinement boost.

World's First Self-Regenerating Catalyst
The new Sirion 1.3 litre launched in 2005 featured the world's first self-regenerating catalyst. This innovation is also standard on the new Copen 1.3 and now the new 1.5 litre Daihatsu Materia.

It effectively extends the life of the catalytic converter, reducing maintenance costs and is kinder to the environment as it keeps the catalyst 'healthier' over a higher mileage meaning the already low 169 g/km does not increase as the engine becomes older.

This revolutionary technology works by providing a self-regenerating capability in the particles of the precious metal which normally degrades.

Using nanotechnology, the intelligent catalyst incorporates metallic ions of palladium, the most heat-sensitive of the metals used in a catalytic converter.

According to temperature and available oxygen, the particles turn in and out of a crystalline state therefore regenerating and prolonging the cat's ability to clean exhaust gasses.

European-Tuned Chassis
Daihatsu has tuned the Materia's chassis for European markets and the result is a firmly-damped but smooth ride and excellent control of body roll despite the car's higher-than average stance.

The power-steering is well-weighted, with good straight-line stability and reassuring self-centring. Meanwhile, the front and rear anti-roll bars coupled with generous low-profile tyres keep understeer well in check.

Front suspension is by MacPherson struts with a long-travel design for an absorbent ride, while the anti-roll bar - specially developed for export - reduces body lean.

The semi-independent rear features a conventional torsion beam and coil springs with separate shock absorbers. The anti-roll bar is complemented by a curved shape to the torsion beam which further improves roll stiffness.

The Daihatsu Materia has a conventional hydraulic power-assisted rack-and-pinion steering system as opposed to the growing trend towards electric power-assistance. The benefits are greater feel and sensitivity.

High Safety Levels
Safety is given high priority in the Daihatsu Materia, especially considering its likely roll as a family car. It therefore has all the latest life-saving and injury-reducing initiatives.

For example, both front seats have seatbelt pretensioners and force limiters. These are designed to provide just the right amount of restraint for the level of retardation.

All three rear seatbelts have three-point occupant protection. The outer rear seats also offer the more secure ISOFIX child-seat mounting points.

Should parents wish to carry their offspring in a child seat placed on the front passenger seat, a switch can be used to disable the passenger airbag.

Twin front airbags and side airbags are also standard as are dual side-impact door beams. The body structure is designed to absorb all-angle impacts while maintaining survival space around the occupants.

Various materials are used around the cabin to minimise impact injury such as to the knees and lower legs, while the brake pedal features a special mechanism which reduces intrusion into the cabin.

The braking system features servo-assisted front ventilated disc brakes and rear drums. Anti-lock (ABS) is also standard as is Electronic Brakeforce Distribution (EBD) which further avoids the locking-up of individual wheels during severe braking.

Sports-car lovers will be treated to a tantalising glimpse of Toyota's future with the unveiling of the Toyota FT-86G Sports Concept at the 2010 Australian International Motor Show.

The dramatic show car previews a rear-wheel-drive sports coupe that is destined to add appeal and excitement to the Toyota brand post 2012.

As the concept car illustrates, the production model is the spiritual successor to Toyota's sports-car heritage that features names such as Supra and MR2.

Its named is derived from the AE-86 Corolla - a small, light-weight, rear-wheel drive coupe from the 1980s that has achieved cult status.

Toyota's aim is to bring a new level of excitement to Toyota showrooms and customers, connecting with younger drivers and promoting the fun of sports-car driving.

The Toyota FT-86G is the second concept revealed by Toyota in the past year that points to a next-generation production sports coupe.

It has gained tweaks to performance and styling that make it sleeker and more aggressive than the Toyota FT-86 concept shown at 2009 Tokyo Motor Show.

The "G" suffix signifies a sports conversion that has stretched the original by 30mm, widened it by 20mm and lowered it by 30mm (4190mm × 1780mm × 1230mm).

Sharper looks come from a totally redesigned front end that incorporates a larger air intake with visible intercooler, as well as a vented bonnet.

At the rear, a large carbon-fibre wing, diffuser and oversized twin exhausts contribute to the edgier styling.

The Toyota FT-86G Sports Concept sits on low-profile Bridgestone 19-inch rubber - 245/40 at the front and 275/35 at the rear, while Recaro sports seats complete the "G" conversion of the dynamic four-seater.

The concept retains classic sports-car underpinnings with a front-mounted 2.0-litre engine - now boosted with a turbo - driving the rear wheels through a six-speed manual transmission.

Toyota's plan to return to the sports-car market is in response to the edict by global president Akio Toyoda for the company to re-connect with younger buyers by producing fun-to-drive models.

"It is often said that young people today have drifted away from cars, but I feel it may not be the customers who have drifted from cars but us, the manufacturers," Mr Toyoda said. "I believe it is the mission of auto makers to provide the fundamental excitement of automobiles to customers, regardless of the era."

2010 TOYOTA RAV4 EV Concept japan automobiles pivtures

Toyota U.S.A., Inc. debuted the second-generation Toyota RAV4 EV Concept at a news conference at the 2010 Los Angeles Auto Show. A total of 35 vehicles will be built for a demonstration and evaluation program through 2011, aiming at market arrival of a fully-engineered vehicle in 2012. The fully-engineered vehicle will have a target range of 100 miles in actual road driving patterns, in a wide range of climates and conditions.
Toyota U.S.A., Inc. debuted the second-generation Toyota RAV4 EV Concept at a news conference at the 2010 Los Angeles Auto Show. A total of 35 vehicles will be built for a demonstration and evaluation program through 2011, aiming at market arrival of a fully-engineered vehicle in 2012. The fully-engineered vehicle will have a target range of 100 miles in actual road driving patterns, in a wide range of climates and conditions.

"When we decided to work together on the RAV4 EV, President Akio Toyoda wanted to adopt a new development model that incorporated Tesla's streamlined, quick-action approach," said Jim Lentz, president and chief operating officer, TMS. "The result was a hybrid - a new decision and approval process and a development style that our engineers refer to as "fast and flexible."

Led by the Toyota Motor Engineering and Manufacturing North America (TEMA) Technical Center in Michigan, the new development model helped reduce development time without compromising product quality. The team has accomplished this by approaching the project as they would a typical mid-cycle "major-minor" product change. Specifically, midway through a generation, the team began with a fully engineered current-generation RAV4, to which was added a major powertrain option, along with minor feature and cosmetic changes.

Tesla was responsible for building and supplying the battery, as well as other related parts, that met specific Toyota engineering specifications in performance, quality and durability. Toyota was responsible for development and manufacturing leadership and the seamless integration of the powertrain.

"From the beginning, the customer experience has been the focus," said Lentz. "In other words, how do we deliver an unconventional product to mainstream customers that is compelling and affordable and that offers an acceptable level of daily convenience."

A large part of the team's focus on the customer experience targeted driveability. In this case, the end goal is a vehicle with driveability characteristics as close to the conventional RAV4 as possible.

For example, the demonstration vehicle weighs approximately 220 pounds more than the current RAV4 V6 yet it will accelerate from zero to sixty nearly as quickly.

This added weight factor required significant retuning of major components and a prioritized focus on weight distribution. Not only were suspension and steering modified significantly, major components needed to be relocated to better balance the increased mass of the battery pack.

The demonstration vehicle Toyota is currently testing is powered by a lithium metal oxide battery with useable output rated in the mid-30 kwh range. However, many decisions regarding both the product, as well as the business model, have not been finalized. Battery size and final output ratings, as well as pricing and volume projections of the vehicle Toyota plans to bring to market in 2012, have not been decided.

As for a final assembly location, Toyota is considering many options and combinations. The basic vehicle will continue to be built at its Canadian production facility in Woodstock, Ontario. Tesla will build the battery and related parts and components at its new facility in Palo Alto, Calif. The method and installation location of the Tesla components into the vehicle is being discussed.

The Toyota RAV4 EV received several distinct exterior styling changes including a new front bumper, grille, fog lamps and head lamps. New EV badging and the custom "mutually exclusive" paint color, completed the transformation. The interior received custom seat trim, multimedia dash displays, push-button shifter and dashboard meters. The RAV4 platform brings a 73-cubic-foot cargo area with rear seats folded down - no cargo space was lost in the conversion to an electric powertrain.

In 1997, Toyota brought to market the first-generation Toyota RAV4 EV in response to the California zero emission vehicle (ZEV) mandate and was the first manufacturer to meet the mandate's Memo of Agreement on volume sales. Powered by a nickel-metal hydride battery pack, the vehicle had a range of between 80-110 miles on a single charge. From model year 1998 to model year 2003, only 1,484 vehicles were sold or leased in the U.S. 746 first-generation Toyota RAV4 EVs are still on the road (www.toyotarav4ev.com).

"Price and convenience proved to be critical success factors and they remain so today," said Lentz. "But much has changed in the last few years. Most importantly, the growing level of awareness that sustainable mobility will come at a cost that must be shared by the automakers, government and the consumer."

Toyota's approach to sustainable mobility focuses on the world's future reliance on mobility systems tailored to specific regions or markets, rather than individual models or technologies. It acknowledges that no one technology will be the "winner" and that a mobility system in Los Angeles will probably look very different from one in Dallas or New York or London or Shanghai.

Toyota's comprehensive technology strategy is a portfolio approach that includes a long-term commitment to hydrogen fuel cells, plug-in hybrids and battery electrics all driven by the further proliferation of conventional gas-electric hybrids, like Prius, as its core technology.

Toyota has announced that coinciding with the arrival of the Toyota RAV4 EV in 2012 it will launch, in key global markets, the Prius PHV (plug-in hybrid) and a small EV commuter vehicle. It will also launch, in key global markets, its first commercialized hydrogen fuel cell vehicle in calendar year 2015, or sooner. Finally, by the end of 2012, Toyota will add seven all new (not next-generation) hybrid models to its portfolio.

The Lexus CT 200h was designed and developed with the European market in mind. Lexus's first five-door compact car, its size, packaging, full hybrid technology and low emissions fully address the requirements of discerning, environment-conscious customers in a key market sector. At the same time, it does not compromise the quality, refinement and driving pleasure that are the hallmarks of every Lexus.

The new Lexus CT 200h is the first full hybrid vehicle to be launched in the premium compact segment. Entering production in late 2010 and set for sale worldwide, the full hybrid model will provide a new gateway to the Lexus range and attract new, younger customers to the brand.

The Lexus CT 200h was designed and developed with the European market in mind. Lexus's first five-door compact car, its size, packaging, full hybrid technology and low emissions fully address the requirements of discerning, environment-conscious customers in a key market sector. At the same time, it does not compromise the quality, refinement and driving pleasure that are the hallmarks of every Lexus.

Exterior and interior design
The production-ready Lexus CT 200h retains strong visual links to the LF-Ch Concept unveiled at the 2009 Frankfurt motor show. Its styling marks a powerful evolution of Lexus's L-finesse design philosophy with a distinctive, sharp-edged look that sets it apart from its premium compact rivals.

The exterior is styled for maximum aerodynamic efficiency and minimum wind noise. The strong front grille, directly referencing the LF-Ch concept sits over a full-width bumper and air dam. The headlamp units, positioned higher than the grille (a signature feature of L-finesse design), incorporate LED daytime running lights.

In profile, the steeply raked windscreen, long, flowing roofline and Lexus slingshot window graphic combine to create an elegant and distinctive silhouette. The front and rear corners have been pulled in tight and the wings are styled to improve airflow down the sides of the vehicle.

At the rear, the trailing edge of the roof overhangs a wide, wraparound rear window to create a seamless, integrated spoiler. A pronounced step in the tailgate section flows from the shoulders of the rear wheelarches and is anchored by a tail lamp design that displays the L-shaped motif that Lexus first introduced on the current LS model.

The interior combines superior ergonomics with extensive use of metallic finishes and dark, soft-touch surfaces.

Lexus has retained the asymmetrical dashboard design seen in the LF-Ch show car. Based on the Future Lexus Interior concept, the dashboard is split into an upper Display Zone, with an eight-inch LCD multi-display screen; and a lower Operation Zone, with the shift lever and other controls such as Lexus's Remote Touch multi-function controller.

In keeping with the car's performance, the driving position is set low, with a highly supportive driver's seat. The instrument binnacle houses large, twin dials; in SPORT mode, the hybrid indicator in the binnacle functions as a tachometer and the ambient lighting turns from blue to red. The two-mode switch ring and a spotlight in the centre cluster also light up in red, changing the whole atmosphere of the cabin.

In spite of its compact, efficient design, the Lexus CT 200h offers a roomy interior. The 2,600mm wheelbase allows for front and rear passenger accommodation that is among the most spacious in the segment. Luggage capacity is 345 litres, increasing to 700 litres with the rear seats lowered.

Lexus Hybrid Drive
The Lexus Hybrid Drive system in the Lexus CT 200h combines a 1.8-litre VVT-i petrol engine with a powerful electric motor. Drivers have the choice of four selectable drive modes: ECO and NORMAL place the emphasis on efficiency and comfort, while SPORT focuses on dynamic performance.

Unlike mild hybrid systems used by other manufacturers, the Lexus CT 200h also has an EV (electric vehicle) mode that allows for ultra-quiet running on the electric motor alone, resulting in zero fuel consumption and CO2, NOx and particulate emissions. The car is capable of running in EV mode for up to 1.2 miles at speeds up to 28mph.

Chassis and suspension
The Lexus CT 200h is built on a new platform with a dedicated double wishbone and trailing arm rear suspension system. It has been developed specifically to combine the ride comfort expected of a Lexus with superior driving involvement and handling agility.

Several elements in the MacPherson strut design have been exclusively developed for the mode, including the coil springs and shock absorbers, and a new front anti-roll bar has been designed to deliver improved roll rigidity.

The double wishbone rear suspension is exclusive to the Lexus CT 200h and incorporates a lightweight trailing arm. The springs and shocks are positioned separately to minimise intrusion into the loadspace floor.

2008 LEXUS LF-A Roadster Concept
Click Thumbnail to download (size 1600 x 1200 pixels)

The engineers and designers at Lexus continue to use their groundbreaking LF-A premium sports car concept as a medium for expressing their ideas about what a high-performance sporting vehicle not only can be, but should be. In this latest expression of the LF-A, they have removed the car's top to create a high-performance roadster.

The LF-A Roadster is based on the sturdy yet lightweight carbon-fiber and aluminum body used for the LF-A coupe, which helps maintain the structure's strength and rigidity even without a top.

Like its coupe counterpart, the LF-A Roadster is powered by a high-revving V10 engine that approaches 5.0 liters in displacement. The V10, capable of more than 500 horsepower and test-track speeds greater than 200 mph, is mounted in front of the passenger compartment but behind the front-axle centerline in what the LF-A's engineers refer to as a "front-mid" configuration.

The engine is connected via a torque tube and propeller shaft to a transaxle that is controlled by paddle shifters. The torque tube is a structural member that adds rigidity to the drivetrain and chassis while also reducing vibration.

Styling is rooted in the Lexus L-Finesse design philosophy, conferring the LF-A Roadster's front end with a compact, low-profile, aerodynamic shape. Like its coupe counterpart, the LF-A Roadster stands just 48 inches tall, but the Roadster configuration adds a speed adaptive rear wing.

The rear is marked by a pair of wrap-around, arrowhead-shaped taillights that bracket a pair of large grilles. These grilles vent the heated air from the car's two rear-mounted radiators into the LF-A Roadster's aerodynamic wake. The radiators are fed cool air by two large intake ducts mounted just above the rear wheel wells. This aft radiator positioning not only allowed the designers to keep the car's front profile low and tight but also aided the LF-A's chassis engineers in their search for optimal weight distribution.

Helping to provide balance and scale to the design, which features an overall length of 175.6 inches and a wheelbase of 102.6 inches, are high-performance tires on turbine-styled alloy wheels. The front tires are 265/35R20s, while the rears are 305/30R20s. Like the LF-A coupe, the brakes consist of 14.2-inch cross-drilled, vented discs up front, and 13.6-inch cross-drilled, vented discs at the rear. The front brake calipers are six-piston units and the rear calipers use four pistons each.
An "F" logo, located on each front fender of the Roadster, indicates the vehicle's status as a part of the new "F" marque. The name is derived from the original "F" designation for the first Lexus LS prototype. That vehicle was internally coded "Circle-F," with the "F" standing for "flagship." The Circle-F designation further evolved into the code name Flagship One, or F1, and the first F1 concept developed into Lexus' first vehicle, the LS. Since then, the "F" code has come to signify a special vehicle program within Lexus that falls outside the normal engineering and development process. In addition, Fuji Speedway is the IS F's home circuit, and the shape of the F-logo was inspired by many of the track's turns. The all-new Lexus IS F sport sedan is the first production vehicle to carry the F marque.
