Sometimes great things happen when old designs inspire thoroughly modern engineering. Such is the case with Audi’s 2.5-litre five-cylinder turbocharged petrol engine.
It gives a nod to Audi’s rally heritage and the engines fitted to its championship-winning cars of the 1980s – the Quattro is nothing less than a legend.
In those days the engine was smaller, yet it didn’t lack punch. In the most potent road car the old 2.2-litre engine produced 306bhp, while the most highly-tuned fire-spitting rally car had an incredible 720bhp and reached 60mph in less than three seconds.
