The DTM, Germany’s high-profile, high-powered touring car series, returns to Brands Hatch this weekend – but it’s not the DTM as we’ve always known it.

First, traditional but outdated V8s have been ditched in favour of in-vogue turbocharged four-cylinder engines. Uh-oh. If that’s not hard enough to swallow for a series built on old-school bombast, Mercedes-Benz – king of the DTM pretty much for ever – has withdrawn, replaced in part by a new effort under the guise of… Aston Martin. Eh? What on earth is going on?

Never fear. As Scottish DTM veteran and ex-Force India Formula 1 ace Paul di Resta assures us, the DTM might be different, but it hasn’t really changed. “Honestly, if you didn’t know the engines were different you wouldn’t notice from the sound,” he says. “The cars are quicker, too. They generate the power in a different way, they are very torquey – and they are fun to drive. They are brutal and still give the same old aspects to the fans: raw noise and excitement.”
