Revised two-door models set to make public debut at next week’s Big Apple event
The appearance of the reworked two-door C-Class models follows the unveiling of the facelifted four-door C-Class saloon and estate at the recent Geneva motor show. Along with some predictably subtle exterior styling tweaks and upgraded interior appointments, they have a series of midlife mechanical changes, including a more powerful engine in the four-wheel-drive C43 4Matic.
That model retains the same turbocharged 3.0-litre V6 petrol engine used by the predecessor saloon, estate, coupé and cabriolet models, but gains an additional 23bhp (to 386bhp) while running the same 383lb ft of torque as before.
Despite the increase in power for the new C43 4Matic, though, Mercedes-AMG quotes the same 0-62mph and top speed figures as the outgoing model at a respective 4.7sec and limited 155mph.
Also new for the facelifted C-Class is an entry-level EQ Boost mild-hybrid powertrain to be offered in selected markets, including the UK, from the middle of the year.
Based on Mercedes’ newly developed turbocharged 1.5-litre four-cylinder petrol engine producing 181bhp and 206lb ft of torque, the powertrain features a belt-driven alternator capable of providing an additional 140bhp and 118lb ft of torque for short periods for improved accelerative ability and smoothness at low revs.
To be fitted to the C200 EQ Boost and C200 4Matic EQ Boost saloon, estate, coupé and cabriolet models, the new petrol-electric powertrain also receives a 48V electric architecture for added efficiency. It operates in combination with the belt-driven alternator and lithium-ion battery to recuperate up to 12kW of kinetic energy during braking, as well as providing a coasting function that idles the engine during extended periods on the overrun.
In the new C200 EQ Boost Coupé, which comes as standard with a nine-speed torque converter-equipped automatic transmission, the mild-hybrid powertrain provides 0-62mph acceleration in 7.9sec and a top speed of 149mph. Despite confirming it meets the latest Euro6d TEMP emissions standards, Mercedes has yet to provide official fuel consumption and CO2 emission figures for the new model.
The new powertrain is part of a range of petrol-electric units from Mercedes, which also includes the more powerful turbocharged 2.0-litre four-cylinder petrol engine. The unit is based on an EQ Boost system and will be launched in the (yet to be officially confirmed) C300 EQ Boost and C300 4Matic EQ Boost models. They are due in saloon, estate, coupé and cabriolet forms and will go on sale alongside their C200 EQ Boost siblings in July.
Mercedes has yet to confirmed details of the C300 EQ Boost, although insiders have told Autocar that its combustion engine develops 255bhp and 295lb ft, with an added 16bhp and 118lb ft available via a belt-driven alternator.
Further engines confirmed for the 2018 C-Class coupé and cabriolet include a new turbocharged 2.0-litre four-cylinder diesel. It replaces the older turbocharged 2.1-litre unit in the C220d, offering an added 24bhp and the same torque rating at 191bhp and 295lb ft.
In line with their saloon and estate siblings, the C-Class coupé and cabriolet receive a subtle styling refresh with a new-look front bumper and standard-fit diamond-pattern grille insert together with standard LED headlights and full LED tail-lights.
Further changes include new trim elements and colour combinations within the interior, a standard keyless go function, a new-look stop/start button and a remote function for the C-Class cabriolet’s fabric hood, which can now be operated from outside the car.
Buyers can also option the facelifted C-Class coupé and cabriolet with a new digital instrument display that comes with three themes: classic, sport and progressive.
