Central to the appeal of the Audi RS4 Avant is the fact it offers sports car performance with a usable, practical boot.
Just how much of sports car is it compared to, say, a Porsche 911 GTS though? The team at CarWow endeavoured to find out.
With twin-turbo, six-cylinder engines (and Volkswagen Group backing) the RS4 and 911 have a little bit in common. They also both make 331kW of power, although the Audi channels it to all four wheels.
Which is quicker? We won't spoil the result.
