Built five inches shorter than the Porsche 911 but on a wheelbase that is nine inches longer, the Lexus LF-A Concept is almost identical in dimension to the Ferrari F430, and is close to the Mercedes-Benz SL55 and the Aston Martin DB9. It features an engine capable of developing more than 500 horsepower, and the Lexus LF-A Concept is engineered to take advantage of gearing, weight and aerodynamics. Lexus executives say that the LF-A Concept could produce a top speed of 200 miles per hour.
