The Mercedes S-Class Coupe’s front seats are an extremely luxurious place to sit, but space for your rear passengers’ feet is tight and alternatives have more practical boots

Passenger space

Despite its low roof, there’s ample space in the front of the Mercedes S-Class Coupe. You won’t have any trouble getting comfortable if you’re very tall – even in cars with the optional panoramic glass roof – and every model comes with electric seat adjustment as standard.

There’s also four-way lumbar adjustment to help prevent backache on long drives and a memory function for the seat that helps you find your preferred settings if someone else has fiddled with them.

Pay extra for the Premium Plus equipment pack and you also get a range of massage functions for the front seats. Unfortunately, most of the pre-programmed massages feel like you’re being nudged in the back by an irate passenger – not particularly relaxing, then.

The Mercedes S-Class Coupe’s front seats slide forward automatically when you fold them forward which helps make it reasonably easy to climb into the back. Surprisingly, there’s just enough head- and legroom for two six-foot-tall passengers to get fairly comfortable but there’s very little space under the front seats for them to put their feet.

The seats themselves are soft and supportive, and your passengers won’t feel too claustrophobic thanks to the S-Class Coupe’s relatively large windows.

It’s relatively easy to lift in a large child seat through the Mercedes S-Class Coupe’s wide-opening doors, but you’ll have to be careful not to snag any of the soft leather trim as you manoeuvre it in. The Isofix anchor points are hidden behind a padded cushion which makes them hard to access and you’ll have to stoop down to strap in a child if you’re quite tall.

Storage space

The Mercedes S-Class Coupe’s cabin isn’t the biggest around, but it comes with enough handy cubby holes to help you keep it looking tidy. The front door bins are wide enough to hold a 1.0-litre bottle each and there’s space under a lid in the centre console for a pair of large coffee cups.

The glovebox is reasonably deep and there’s plenty of space under the large two-way opening front armrest for a few bulky valuables. There’s a small tray in the back that’s large enough to hold a phone and two extra cupholders built into the rear armrest.

You’d be forgiven for thinking the Mercedes S-Class Coupe’s back seats would be little more than sumptuous leather-clad coffins. Thankfully, they’re spacious enough for adults…

Boot space

The Mercedes S-Class Coupe’s 400-litre boot is significantly larger than the Bentley Continental GT’s load bay, but it can’t quite match the space served up by the BMW 8 Series.

There’s space inside for a set of golf clubs and some soft bags, but there’s a large load lip that makes lifting heavy items in rather tricky. At least the boot opening is wide and square, so long luggage won’t snag as you lift it in and out.

There are a few tether points dotted around the boot so you can secure smaller items, but there isn’t any usable load space under the floor. You don’t get a ski hatch between the back seats to help you carry very long luggage, either, and the back seats don’t fold forwards like in the BMW 8 Series.
