In one corner, can the new RS3 – powered by a 2.5-litre engine with 400hp – defeat the RS5 and its 2.9-litre, twin-turbo V6 with 450hp? In the other, it's old vs new as the RS4 B7 (and its 420hp, 4.2-litre V8) takes on the 347hp DIESEL S4, with a 3.0-litre V6! Who'll come out on top? Join Mat and see! | carwow | Facebook
