Only this time there’s a fundamental difference. The previous model was a highly-tuned turbodiesel. This one, however, has a 3.0-litre turbo V6 petrol engine, good for 0-62mph in 5.4sec and a top speed of 155mph. Surprisingly, it’s a fraction slower than before in the benchmark acceleration test, but it could still be a canny move by Audi, given the current anti-diesel mood.
