Mercedes-Benz has revealed a convertible version of its C-class coupe ahead of its debut at the Geneva motor show tomorrow.

On-sale from the summer, a number of diesel and petrol engines are offered with power outputs between 170hp and 367hp.

The most fleet-friendly model will be the 170hp C220d with the 2.0-litre diesel engine, which emits 116g/km of CO2 and returns 62.7mpg. A more powerful 204hp model – badged C250d – is also offered, which emits 121g/km of CO2 and returns 61.4mpg.

Mercedes will also offer the top-of-the-range C43 AMG performance model. Its 367hp 3.0-litre petrol engine emits 190g/km of CO2 and returns 34mpg.

All engine variants can be optioned with Mercedes’ nine-speed automatic gearbox, while the base C220d model can be fitted with four-wheel-drive.

Based on the roof from the S-class convertible, the C-class’ roof can be opened and closed within 20 seconds at speeds of up to 31mph.

The interior of the C-class cabrio is based on the current C-class coupe. Convertible-specific additions include the company’s Airscarf kneck-level heating system and automatic seatbelt extenders.

Standard safety kit includes the firm’s Attention Assist feature, which warns the driver of drowsiness, Collision Prevention Assist Plus that features acoustic warnings for drivers above 7kph (4.3mph) and Adaptive Brake Assist.

This braking system can carry out autonomous braking at up to 200km/h to help reduce the severity of collisions with slower vehicles. At speeds of up to 50kph (31mph) the system is able to brake in response to stationary vehicles and is able to prevent rear-end collisions while travelling at speeds of up to 40kph (24.8mph).

The C-class cabrio also features the firm’s Connect Me package of remote online services including eCall, accident recovery and breakdown recovery. Optional extras include vehicle tracking and a remote door locking and unlocking feature.

 

Meanwhile, Mercedes claims its media system’s listening experience is “almost on a par with a concert hall”, while the sat-nav features an animated compass and Google Maps displays on the heads-up display.
