Audi R8 / Lamborghini Gallardo
These two exotics have the same V-10 engine (although a V-8 is available in the Audi). Because performance is similar, the cars were introduced at the same time in 2003, and Audi has owned Lamborghini since 1998, they’re often called sister cars.
Similarly equipped, both cars are nearly $200,000 and reach 60 mph in less than four seconds. The Lamborghini claims a 202 mph top speed, 3 mph more than the Audi. The major differences are that the Audi's wheelbase is four inches longer than the Lamborghini's, while the Gallardo’s driving position is lower and the car is considerably lighter due to the use of titanium and carbon fiber over the Audi's aluminum construction.
