The Japanese carmaker supports in its official release that the knowledge gained from the endurance race will be fed back to engineering teams to assist with further development of the LF-A. The concept sportscar was originally shown in 2005 and it's powered by a front mounted 500+ Hp V10 engine.
Lexus finally decided to add a press release to the official image gallery of its Detroit Show LF-A Roadster concept that we first showed you earlier today (click here for the high-resolution pictures). As anticipated, the Roadster is equipped with the same 500 plus horsepower 5.0-liter V10 engine unit as the LF-A Coupe which was unveiled in 2007. Apart from the removal of the roof and the structural reinforcements, the Roadster configuration also adds a speed adaptive rear wing. -Details after the jumpPress Release - Click here for the image gallery
Lexus LF-A Takes on Roadster Form – An Open Version of the Supercar Concept Revealed
January 13, 2008 -
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.

Lexus surprised us today by unveiling a roadster version of last year’s LF-A sports car concept. However, while the Japanese carmaker liberated the high-resolution image gallery of the LF-A Roadster early this morning, we’re still waiting for the official press release. Most probably, the roadster will feature the same running gear as the coupe – a front-mounted 500 HP 5.0-liter V10 powering the rear wheels. We’ll have more on Lexus’ latest concept later on the day, but for the time being follow the jump to check out our high-res image gallery. -Continued
