Mercedes S-Class Coupé review

Space up front is incredibly generous; even with the standard-fit panoramic glass roof, there's loads of room in all directions for two tall adults. If anything, width is its most precious commodity; there are few cars, let alone coupés, that offer such an open and airy cockpit environment.

Predictably for a coupé, though, the back seats are less roomy. A 6ft-tall adult will just about fit, just not particularly contentedly if the journey is longer than 20 minutes. Nevertheless, they will be far happier in the S-Class Coupé than they would in the back of the impossibly claustrophobic Aston Martin DB11.

At 400 litres, the S-Class Coupé's boot is more spacious than those in most of its rivals, too. That's easily enough room for your golf clubs or a generous selection of luggage for a weekend away.
