With more shoulder room and a bigger capacity boot, the car is overall a significant move onwards for the nameplate in its fourth generation.
There are also new engines, including 1.3 and 2.0 petrol units and a 1.5 diesel.
Semi-autonomous driving will also be available in certain conditions, according to the company. The full range of current Mercedes-Benz connectivity and safety technologies will be included in the specifications.
First market launches commence in May.
