Mercedes has revealed the facelifted GLC Coupe which introduces a range of new engines and some styling tweaks.

The new line-up will be offered with RDE2 compliant diesel engines, meaning they avoid the 4% benefit-in-kind tax supplement.

The new GLC Coupe also features the latest generation of the MBUX Mercedes-Benz User Experience multimedia system with its wide range of control options.

New driving assistance systems include an exit-warning function, emergency-corridor function and tail-end-of-traffic-jam function.

The low slung roof and sleek body of the GLC Coupe remain, with an enhanced front end that gives greater road presence.

Revisions to the interior include a larger infotainment display and digital instrument cluster.

A multifunctional touchpad on the centre console improves operating convenience of infotainment system and replaces the rotary pushbutton.

At market launch the GLC Coupe will be available with new engines, with further engines to be added to the line-up during the course of the year. All the diesel models meet the requirements of the RDE2, which comes into force in 2020.

The petrol engines are electrified by the integration of a 48-volt on-board electrical system (EQ Boost). The belt-driven starter-generator is responsible for hybrid functions such as boost or energy recuperation, while allowing fuel savings that were previously the reserve of high-voltage hybrid technology. In addition to reducing consumption and CO2 emissions, the technology also enhances both comfort and performance.

Fleet customers will find the GLC 200d and GLC 220d the most efficient. They both emit from 137g/km of CO2 and achieve up to 54mpg average fuel consumption.

The 200d produces 163PS, while the 220d has 194PS. A more powerful 300d, with 245PS is also available but emits more CO2 (151g/km).

There a two petrol models: the 200 and 300. They develop 197PS and 258PS respectively. CO2 emissions for both start at 161g/km.

All versions have 4Matic all-wheel-drive.

Prices and specifications are expected to be released when the car goes on sale in the Spring.
