Weighing 234kg with a 162bhp, 1198cc two-cylinder engine, the Diavel has a power-to-weight ratio of 692bhp per tonne. At the other corner, the 5.2-litre, 542bhp R8 has a power-to-weight figure of 340bhp per tonne.
Looking at the power-to-weight ratio, it looks like the Audi is at a disadvantage. However, this test takes into consideration both acceleration and deceleration of the two vehicles. Who is going to come out on top?
