Audi B9 RS4

The powertrain of this RS4 is very different to its predecessor. Gone is the high-revving, naturally aspirated 4.2-litre V8, along with its dual-clutch transmission, and in comes a 2.9-litre twin turbo V6 hooked up to an eight-speed torque converter. The result is 0-62mph in 4.1sec and a top speed – if you’ve paid to have the limiter raised – of 174mph.
