Four-wheel drive is standard for third-generation four-door coupé; three engines are available from launch
12 December 2017

The third-generation Mercedes-Benz CLS is priced from £57,510 for the entry-level 350d, which was recently revealed at the Los Angeles motor show

Until BMW launches a replacement for the 6 Series Gran Coupé, the only real rival to the CLS is the Audi A7, which currently starts at £48,045, ahead of its replacement by a second generation early next year. 

Price wise, the CLS range so far tops out with the 400d at £60,410, but the most powerful unit at launch is the 3.0-litre petrol engine in the 450 4Matic, with a 48V electric system and EQ Boost integrated starter motor providing mild hybrid properties. It has a claimed 0-62mph time of 4.8sec and limited 155mph top speed. It delivers a nominal 362bhp and 369lb ft, with an additional 22bhp and 184lb ft available for short periods when the integrated starter motor is triggered.

The range uses petrol and diesel in-line six-cylinder engines. All are turbocharged and mated to Mercedes’ in-house nine-speed 9G-Tronic automatic gearbox and with 4Matic four-wheel-drive system as standard. The 350d and 400d share the new 2.9-litre diesel engine in two states of tune.

For the 350d, 400d and 450, Mercedes claims respective fuel economy figures of 48.7mpg, 47.9mpg and 36.2mpg, with CO2 emissions of 156g/km, 156g/km and 184g/km respectively. The CLS is only available in AMG Line trim – this means 19in alloys, a parking pack with reversing camera, ambient lighting and Mercedes' Agility Control adaptive dampers all come as standard.

Shortly after launch, Mercedes plans to introduce the 350. It runs a new turbocharged 2.0-litre petrol engine also featuring electronic boosting qualities. Also planned is the 300d, which employs Mercedes’ widely used turbocharged 2.0-litre four-cylinder diesel engine tuned to deliver 242bhp.

A new CLS 53 is planned to join the mechanically identical E53 coupé and E53 cabriolet models in a three-strong line-up of new AMG models to be unveiled at next year’s Detroit motor show, all featuring a newly developed in-line six-cylinder engine with mild hybrid properties.

First ride: Mercedes-Benz CLS pre-production car

The new petrol engine will usher in electric boosting via an integrated starter motor for added performance potential and is Mercedes’ answer to the likes of the upcoming second-generation Audi S7 and recently introduced BMW M550i.

Details remain scarce, although insiders suggest the engine and integrated starter motor will deliver a combined 450bhp. In the facelifted S500, the new engine provides a nominal 429bhp, with an additional 22bhp delivered by the integrated starter motor for a total of 440bhp.   

With Mercedes planning to replace the existing CLS 63 with an upcoming twin-turbocharged 4.0-litre V8 production version of the five-door AMG GT Concept, the CLS 53 is set to become the top model in the new CLS line-up. 

Opinion: Why the new CLS shows that creases are dead

With more than 350,000 sales to date, the CLS has proven popular since its introduction in 2005. But with prospective customers gravitating more towards Mercedes’ ever-growing line-up of SUV models, worldwide sales have slowed significantly in recent times.

As such, the new model, which goes under the internal codename C257, will only be produced in saloon form. The CLS Shooting Brake, which has failed to live up to early sales expectations following its introduction in 2012, will not be replaced.

As with its predecessors, the CLS relies heavily on the E-Class, from which it borrows its platform, drivelines, chassis, electric architecture and more. It offers three suspension set-ups.

Predictably, Mercedes promises improvements in performance, handling, comfort and safety. At the same time, it says the swoopy saloon also ushers in a new exterior design lineage to be adopted by other Mercedes models in the not-too-distant future.

Mercedes has confirmed to Autocar that the CLS has grown in dimensions compared with the outgoing second-generation model, which has been on sale since 2010. It's grown in length to 4988mm (up from 4937mm for the previous car), in width to 1890mm (from 1881mm) and height to 1428mm (from 1418mm).

The new saloon is also said to feature a wheelbase that's 61mm longer at 2935mm, allowing for larger rear door apertures and easier access to back seats.

The interior of the new CLS is no longer as uniquely styled nor quite as eye-catching as that in previous incarnations of the saloon, which boasted their own bespoke facia. To provide economies of scale with other Mercedes models, it receives a lightly reworked version of the latest E-Class’s dashboard, complete with a so-called Widescreen Cockpit with twin 12.3in displays for the instruments and infotainment system, and a multi-function steering wheel from the facelifted S-Class.

The CLS also gets a centre rear seat as standard, giving the car five-seat capability for the first time. The rear-seat backrests fold in a 40/20/40 configuration to extend the length of the boot, which boasts the same volume as the second-generation model at a nominal 520 litres.

As with the E-Class, the new CLS has five standard driving assistant functions, including lane keeping assist and speed limit assist.

Buyers can also opt for a Driving Assistance Package that adds a further eight systems that provide semi-autonomous properties, including hands-off steering for up to 30 seconds, automatic adjustment of speed before bends or junctions and an automatic lane change function. 

First deliveries of the new CLS are expected to commence for UK buyers in August.

Stick a slab of dual touch screens on top of a bunch of circular air vents....and that's it!

At least for Europe. So how will they justify the many thousands more than an e-class when it  has the same interior? But it looks nice nevertheless.

I felt the first CLS was a stunner and the second generation, while not as good looking, had massive presence and looked expensive. This new, 3rd generation model, from the photos at least, doesn't appear to be any of these and I think it looks rather bland in the same way as the related E-Class coupe does too, especially with the side sheetmetal and the rear end. While the dashboard doesn't appear to be totally bespoke as with previous CLSs I don't think that's a bad thing as the current E Class interior looks superb IMO.

I definitely agree. Progressively, the CLS has become less attractive and sleeker and more vulgar.

As if Mercs weren't already dull looking and sleep inducing, this new CLS takes things to another new level of dullness. It looks so staid, anonymous and cheap which is bad enough for a saloon, but for a coupe that's quite shocking. It says something that a conventional executive saloon, like the Jaguar XF or Volvo S90, can look so much more exciting, desirable and expensive than a coupe from a so-called prestige marque. And I see Mercedes is sticking with that same tacky, awful looking and cheap looking interior as found in the E Class. Yet again Mercedes can't do luxury properly.

Maybe white is not the best colour but, this looks like a low roof perched on top of a fat car.

Citroëniste.

I don’t understand. The Mercedes range was re-badged to bring models and spin-off models into line. So now the new CLS comes along and is based on the E-Class but not named CLE.

....in my eyes, or at least very sensetive to colour and wheel selection. The white and grey models with black wheels in the photos look very poor, almost like its taken a visit to Halford for a body kit and wheels. Much nicer in the red with silver wheels though.

I'm really not a fan of these new air vents Mercerdes have taken a liking to either

It'd be useless for parking up somewhere romantic with a bird.  Looking at that enormous centre console there'd be no chance of leaning over for a bit of action.

I don't need to put my name here, it's on the left

At the front: the relationship between (vaguely Mustang-like) grille and lights is all wrong. At the back: for a 'coupe' it now has more of a notchback profile - why?? This could/should be the next E-Class really; IF the CLS needed replacing (already?) it should've been made far more extreme than this. And as for the interior: the "let's out-pimp Audi AND Bentley" air vents conflict horribly with that 'iPhone' instrument panel, fake-looking wood and travel-sickness inducing curves. But the Chinese will love it...
