Audi has taken the genes of its three-time-LeMans-winning R8, and cooked them into its high-performance LeMans Quattro concept. The stunning car is powered by a twin-turbocharged 5.0-liter V-10 that promises about 600 horsepower and 553 lb-ft of torque. That power is transferred through a sequential-shift gearbox operated via steering wheel paddles, to catapult the two-seater from 0-62 in just 3.7 seconds and to a 155-mph (limited) 214-mph (unlimited) top speed. First shown last month in Frankfurt, the Le Mans was designed to test the market for a premium Audi sports car. If the reaction is strong enough, Audi will work aggressively to make the business case. As the brand becomes increasingly performance-oriented through its impressive S vehicles, the German automaker craves a hallowed performance icon. Judging from response so far, you just may be looking at it with the Le Mans concept.
