Mercedes-Benz CLS Coupe (2018 - ) review
The CLS is a luxury saloon that’s trying to be a coupe, with four doors but rakish styling. It’s a direct rival for Audi’s A7 Sportback.

How good does it look?
Is the CLS a looker? We’ll let you be the judge of that, but it mixes coupe looks and saloon practicality well when it comes to the styling, with a sweeping roof line at the back. In the UK, non-AMG versions of the CLS come in just one trim, called (slightly confusingly) AMG Line. This means even the entry-level car has 19-inch alloy wheels, a sporty-looking bodykit and, impressively, Mercedes' Multibeam lighting system. This uses an array of LEDs in each headlight to enable you to have high beam on at night, while sensors track oncoming cars and put them in shadow to avoid dazzling them. It’s a system that’s been around a couple of years, but is usually an expensive option, so it’s nice to see it as standard, and it works very well.
What's the interior like?
The interior of the CLS is generally excellent. The build quality is not quite as rock solid as Audi's A7 Sportback, with a few hard plastics dotted around if you look for them, but overall it’s still very good. The design is funky and contemporary, and the configurable mood lighting that runs around the cabin and even in the air vents is a nice touch, with virtually all colours of the rainbow available. So, if you fancy driving through the night while bathed in hot pink light, you’re in luck.
The seats are very comfortable and adjust in all manner of ways, and while the infotainment system will require some time spent to understand everything it can do – and it can do a lot – we’ve found it straightforward to operate using a dial and touchpad between the front seats.
How practical is it?
The CLS is a large car, but the swooping roof line means limited rear headroom for taller adults, something that’s not such an issue in the Audi A7 Sportback. However, legroom is decent, and there are plenty of places to keep stuff around the cabin, with two good-size cupholders, sizable door pockets and a storage space under the central arm rest. The boot is impressively large, although it uses a conventional saloon-style boot lid, which means the space is not as accessible as with the A7’s hatchback.
What's it like to drive?
So far, we’ve only driven the CLS on the international launch event, which was plagued by unseasonably cold weather and snow. So, with the caveat that the test cars had winter tyres and the road surface was horrible, we can say the CLS felt impressively assured through the bends and rode extremely well on the optional Air Body Control air suspension. We’ll try the standard set-up on UK roads as soon as we can, but on first impressions it felt less firm than the (also optional) air suspension on the A7 Sportback, but without adversely affecting the handling. The steering has plenty of weight to give a feeling of solidity through the corners, and it all adds up to a very pleasant, comfortable and relaxing drive.
How powerful is it?
We’ve tried two of the available engine options. The best-selling version of the CLS is likely to be the diesel-powered 350d, which has a not-unreasonable 286 horsepower. It’s a strong, effortless engine that makes for easy progress, and the nine-speed automatic gearbox, which is found across the CLS range, is seamless in its shifting.
The fire-breather of the range, due out later in 2018, will be the CLS53, which comes courtesy of Mercedes’ tuning department, AMG. It houses a 3.0-litre, six-cylinder unit under the bonnet, producing 435 horsepower. We’ve had a very quick go in it, and that power means serious performance, although it doesn’t have the brutal, savage delivery you might expect if you’ve tried other AMG products. If you’re after that, you might have to look more towards the forthcoming AMG GT 4-Door Coupe.
The CLS53 is quick, helped by standard all-wheel drive, but it won’t blow your socks and ears off when you put your foot down. We’ll let you decide if that’s good or not. Both the CLS53 and the CLS 450 feature something called EQ Boost, which is a small electric motor that adds 22 extra horsepower for short periods. It doesn’t make for a full hybrid car, but gives you an instant shove of grunt when you put your foot down.
How much will it cost me?
This is a luxury car and expect to pay accordingly. But for the market it targets, the CLS looks like good value. The CLS 350d, which will likely be the biggest seller, is fractionally cheaper than the equivalent Audi A7 Sportback. Both claim exactly the same combined fuel economy, sit in the same insurance group and are expected to cost the same to service, maintain and repair, so they’ve very evenly matched. However, the Mercedes has a considerable advantage when it comes to expected resale value, which will likely make it cheaper to run overall.
How reliable is it?
The CLS is a new model, so no data yet exists for how reliable it is. Data from Warranty Direct doesn’t paint a particularly rosy picture for Mercedes as a brand, with below average reliability among other manufacturers, based on historic performance. It’s slightly better in the more-recent 2017 Vehicle Dependability Study, conducted by JD Power, in which Mercedes performed a little better than the industry average. We’re hopeful the new CLS will continue the improvement.
How safe is it?
The CLS hasn’t been crash tested by safety organisation Euro NCAP, but all recent Mercedes models that have, scored the maximum five-star score, and we have no reason to suspect the CLS wouldn’t too.
All UK cars include seven airbags as standard, two Isofix child seat mounting points in the back, and automatic emergency braking, which will warn the driver of an impending accident and brake automatically if no action is taken. Lane keep assist is also included, which warns you if you’re unintentionally drifting out of lane, and nudges the steering to bring you back.
How much equipment do I get?
With only one trim level available, you get an impressive array of features included as standard, including electric seats, leather upholstery, keyless entry and engine start/stop via a button on the dash, and a digital dashboard in place of traditional, analogue dials. Opt for the Premium Plus package and you can add a sunroof and a 360-degree parking camera that gives you a handy bird’s-eye view of the car’s surroundings. There’s an upgraded Burmester sound system too. The Comfort package adds the air suspension system, and even an interior fragrance dispenser. Mmm.
The CLS is an excellent luxury car with a lavish interior and plenty of state-of-the-art technology. We’d like to try more versions on UK roads before giving a definitive verdict, but based on our experience it offers a more wafting driving experience than Audi’s A7 Sportback while retaining a sense of solidity on the road. However, the styling means headroom in the back is compromised, which is worth bearing in mind if you’ll be ferrying adult passengers. That said, if a stylish, large luxury car is what you’re after, the CLS should be high on your list.
