Review

Not only is the Mercedes S-Class packed to the rafters with technology, but it’s also a very comfortable and exceedingly well-appointed luxury saloon and one of the best for rear seat passengers. The Audi A8 is more refined, particularly if you're looking for a diesel, but the S-Class beats it for wow factor.

Entry-level AMG Line gets plenty of kit including 19in alloy wheels, air suspension, keyless entry and start, metallic paint, adaptive LED headlights, front and rear parking sensors, a reversing camera, soft-close doors and a powered boot lid. Step inside and you’ll find nappa leather covering the heated front and rear seats, with full electric adjustment, including lumbar support, up front. Then there's the four-zone climate control, the nine-speaker stereo, the 12.3in digital driver’s display, the 12.8in infotainment system with wireless smartphone charging and the 64-colour ambient LED lighting. We'd go for the next model up, though, which is AMG Line Premium. It adds the option of the long wheelbase, plus electrically operated and cooled rear seats, a panoramic sunroof, a 360-deg parking camera and a 710-watt/ 15-speaker Burmester sound system.

This entry-level engine is by no means small and weedy. It’s a 2.9-litre six-cylinder diesel with a healthy 282bhp to give 0-62mph in 6.4sec. Fitted to a standard-length S-Class it’s good for more than 40mpg according to official figures, with long-wheelbase models dropping to just below that. Even so, CO2 emissions are high enough to put it in the 37% tax bracket. It can sound a little grumbly under load and sends some unwelcome vibrations through the pedals and steering wheel, which is partly why we prefer the S500 petrol.
