The new Audi RS6 Avant features a twin-turbocharged 4.0-litre V8 with 412 kW, 700 Nm of torque and 0 – 100 km/h sprint time of just 3.9 seconds. The Audi RS4 Avant that we tested recently isn’t slow either. It may lack the turbos, but it also lacks 145 kg. Can it nip at the heels of the larger RS6 in a 1 km sprint and can the RS6 do the same to the Nissan GT-R?
