Audi enters into the supercar world with a bang.  Based off the LeMans Quattro concept, the R8 features a 420 HP V8 good for a 0-60mph of 4.4 seconds and top speed of 186 MPH.   At 7,800 rpm the 4.2-liter engine delivers 420 bhp of power output. Peak torque is 317 lb-ft from 4,500 to 6,000 rpm. And no less than 90 per cent of this maximum torque is maintained consistently throughout a wide engine speed range from 3,500 all the way to 7,600 rpm. As a result of these qualities, the eight-cylinder power unit provides maximum thrust in virtually any driving situation.  Since it's an Audi, it features quattro permanent all wheel drive for maximum grip and launching capabilities.
