One of the most striking cars this show season is unquestionably the LF-A sports car. Toyota has been caught testing such a car, making this much more than a sheetmetal fantasy. Like the other LF concepts that foretell of the IS replacement, this supercar bears the exterior styling language known as "L-Finesse" that will shape future Lexus models. Rumors had been corroborated by official information that this high-speed wedge is powered by a 500-plus horsepower engine. Spies report that Toyota has been testing a V-10 engine, but a similar output V-8 is likely. "The LF-A is theoretically developed to run a parallel course to our company's efforts in Formula One racing," added Jim Press, Toyota Motor Sales executive vice president and COO. "It would probably feature a powertrain and drivetrain configuration strongly influenced by whatever is being used in competition at the time." Although it is about five inches shorter in length than the Porsche 911 Turbo, its wheelbase is nine inches longer. At 48 inches, it is nearly identical in height to the Ferrari F430. And with a width of 73.2 inches, it splits the difference between the Mercedes Benz SL55 and the Aston Martin DB9. Heir to the Toyota Supra mantle? We expect so.
