Just in time for the start of summer, Mercedes has launched its first C-class convertible. Its fully automatic soft top is available in four colors and opens or closes in 20 seconds while driving up to speeds of 50 km/h.The automatic wind deflector system AIRCAP and neck-level heating AIRSCARF means you can enjoy open-topped driving even in the colder season. We tested the new convertible with the C300 engine, which produces 180 kW. The open 4-seater accelerates from zero to 100 in 6.4 seconds. Top speed is electronically limited to 250 km/h.
