Ten Second Review

Despite the rise and rise of the SUV, the C-Class continues to be Mercedes' best selling international model. No pressure then for this redesigned fifth generation 'W206'-series version. Which fully embraces various forms of engine electrification. And brings more than a dash of S-Class luxury to this important segment.

Background

Thinking of a German mid-sized premium badged saloon or estate? If so, then your options have always been pretty straightforward; the dynamic drive of a BMW 3 Series, the uber-cool technology of an Audi A4 or the aspirational image of a Mercedes C-Class. With this fifth generation 'C' though, Mercedes wants to offer more; a sharper drive to temp BMW folk; and a big enough step forward in technology and efficiency to make a potential Audi customer think again. We've heard this before down the decades of course, since the first generation 'W202'-series C-Class was first introduced back in 1993. Particularly with this MK5 model's 'W205'-series predecessor, launched in 2014 which went on to sell 2.5 million units. But there are strong grounds for Mercedes' claims for conquest business this time round. Under the skin, many aspects of its updated 'MRA' ('Mercedes Rear Architecture') platform are shared with the latest S-Class - as is much else. The aim is to redefine what 'luxury' means in this segment. Sounds promising. Let's take a look.

Driving Experience

There's quite a change here. This latest C-Class is powered only by electrified four cylinder powerplants - yes, right up to the top C 63 AMG variant. The mainstream engines have mild hybrid tech, with pricier plug-in options if you want them. The entry petrol model is the C200, which has a 1.5-litre unit offering 204hp. Next up is the 2.0-litre C300 with 258hp. Mercedes hasn't abandoned diesel either. There are two options, both of which use a revised 2.0-litre unit, which now gets an extra 42cc of capacity. The C220d has 197hp and the top C300d has 265hp. All C-Class models have to be had with 9-speed automatic transmission. We mentioned plug-in options, said by Mercedes to be 'significantly more electric' - and so it proves. Courtesy of a much larger 25kWh battery pack beneath the boot floor, the C300e petrol PHEV manages between 34 and 62 miles of all-electric driving range. It's also pretty quick, courtesy of a combined 304hp output and can drive in all-electric mode at up to 87mph. Mercedes has decided that overall, this fifth generation C-Class should be a little more engaging and, in its own words, 'significantly more electric'. And that's pretty much what you get. Push on a little around secondary road twists and turns and you'll discover that the car feels a little lighter and more agile than before; the steering's that bit more accurate, the grip that bit more tenacious. Is it BMW 3 Series-like? Not quite, but in terms of handling feedback, this 'C' has been lifted well clear of what used to be its most dynamically comparable rival, Audi's A4. The firm lowered sports suspension that most models have to have delivers excellent body control, but the downside of that is an unsettled ride over bumpy surfaces - which you can't do anything about because adaptive damping isn't an option for our market. At the top of the range, Mercedes has engineered the usual flagship high performance AMG 4MATIC models to complete the range. These both now have four cylinders, starting with the 402hp C 43, which is a mild hybrid. The top Mercedes-AMG C 63 S E Performance variant is a four cylinder PHEV with a huge 680hp combined output.

Design and Build

From the front end, the design cues echo those introduced with the facelifted E-Class, particularly the grille and the full-LED headlight arrangement. This 'C' has moved closer in size to an 'E' too, being 65mm longer and 10mm wider, though the roof line has fallen by 7mm. Key aesthetic features include the smart bonnet with its twin power bulges and the stronger shoulder line which flows into a neat boot lid that's flanked by angular LED tail lights and which features a subtle integrated spoiler. The previous generation C-Class was heavily influenced by the larger S-Class model, as is this 'W206'-series model - and you notice that most of all inside. A huge portrait-style touchscreen now dominates the centre stack, with three 'jet engine'-style circular vents just above and single vents at either end of the dash. That screen is a real cabin talking point, as is the fact that for the first time in a C-Class, the instrumentation is all fully digital. A 'floating' 10.25-inch digital instrument panel takes the place of the previous more conventional binnacle, with a larger 12.3-inch screen available as an option. Either way, you can customise the display via three 'themes' - 'Discreet', 'Sport' and 'Classic'. Media connectivity takes a big step forward via a second generation version of the MBUX infotainment system. This features over-the-air updates - and live streaming services have been added so that owners can link accounts to services like Spotify and access them in the car. Space in the rear is slightly improved by the 25mm wheelbase length increase, but it's still comfortable for two but a squash for three. Out back, the 455-litre boot capacity is competitive in the saloon but if you prioritise that, you'll want the Estate variant. Its automatic tailgate rises to reveal 490-litres of luggage room, 30-litres more than before. With the seats folded, that rises to 1,510-litres.

Market and Model

Prices are a little above those of the previous generation model, which means a starting point of around £45,000 for the entry-level C200 'AMG Line' saloon. Whatever model you're looking at, allow a premium of around £1.600 if you want the estate version. The mainstream range-topping variant, the C300d 'AMG Line Premium' variant, costs from just over £57,000 in saloon form - or from just under £59,000 as an estate. The mild hybrid Mercedes-AMG C 43 model costs from around £67,000. And the top Mercedes-AMG C 63 S E Performance model costs around £98,000. All C-Class models get the latest generation MBUX media system, including a high-resolution 11.9-inch central media display with its 'Hey Mercedes' virtual assistant. Plus there's a 12.3-inch digital driver display, 18-inch AMG five-spoke alloy wheels, LED high performance headlights with Adaptive Highbeam Assist, a Parking package with reversing camera, heated front seats and wireless smartphone charging. You can also expect to find privacy glass, AMG bodystyling, a multifunction sports steering wheel finished in nappa leather and visible twin exhaust pipes. If you want to go further, the 'Premium' equipment line features 19-inch AMG multi-spoke alloy wheels, Adaptive Highbeam Assist Plus, ambient lighting, illuminated door sills, KEYLESS GO comfort access, MBUX augmented reality for navigation and a 360-degree surround view camera. Finally, 'Premium Plus' trim adds 19-inch AMG five-double-spoke alloy wheels, a panoramic sliding sunroof, a head-up display and Thermotronic four-zone automatic climate control.

Cost of Ownership

Apparently, the Mercedes-AMG Formula 1 team worked with the C-Class development engineers to create a new turbocharger that gives these latest mild hybrid engines better efficiency - and the official readings seem to bear that out. Let's get to the WLTP-rated figures, starting with the petrol mild hybrid models. The 1.5-litre C200 saloon variants return up to 44.1mpg on the combined cycle and up to 146g/km of CO2 (estate up to 42.2mpg and up to 161g/km). For the C300 saloon, the figures are up to 42.2mpg and 152g/km. As for the mild hybrid diesels, well the likely best selling variant, the C220d, manages up to 61.4mpg on the combined cycle and up to 120g/km of CO2 in saloon form (estate up to 60.1mpg and up to 124g/km). The C300d saloon manages up to 55.4mpg and up to 133g/km of CO2 (estate up to 54.3mpg and up to 136g/km). Increasingly though, diesel drivers will be moving towards the various Plug-in options available. The C300e petrol PHEV manages al all-electric driving range of between 34 and 62 miles and can be charged in 30 minutes with a 55kW fast charger (an 11kW device is fitted as standard). The latest plug-in 'C' models also benefit from an adjustable energy recuperation system that can top up the battery at up to 100kW when cruising or decelerating. Mercedes has also added in a hybrid-specific route-planning function that uses the navigation, route topography and traffic data to work out the most efficient route, enabling, for instance, automatic prioritisation of the electric motor in town driving.

Summary

There's the potential for quite a shift here in the segment hierarchy for mid-sized premium badged saloons and estates. To be frank, in its previous guises, the C-Class was a car you usually chose more because it was a Mercedes than because it was intrinsically better than its Audi A4 and BMW 3 Series arch-rivals. But this fifth generation 'C' could potentially tempt you on grounds other than mere badge equity. It now has the segment's classiest and most sophisticated cabin. We also think it has the best interior media set-up. And when it comes to issues of ride and refinement - the things that really matter to potential business customers - there's the potential for class-leading drive dynamics too. The other thing that really matters to those customers is running cost efficiency; well, this Mercedes is class-leading there too. If you're in the market for a car of this kind, that all makes this 'C' a compelling proposition. It'll be interesting to see how BMW and Audi fight back.
