Mercedes-Benz has showcased the new B-Class at the 2018 Paris Motor Show, which goes on sale in December.

The third-generation model features the same MBUX multimedia system as the new A-Class and promises enhanced driveability.

A sportier look is achieved through a longer wheelbase and short overhangs. This also provides more interior space.

Inside, a twin-screen setup is in keeping with the latest models from Mercedes, with two seven-inch displays featuring on the base models and two 10-inch displays on the high-end version.

With seat climate control and multi-contour seats with massage function, the new B-Class is available with optional extras that were previously reserved for vehicles from much higher segments.

The interior has been fine-tuned for practicality. The improved entry aperture to the centre tunnel in the rear makes for a more accessible middle seat. The rear seat backrest comes as standard with a 40:20:40 split.

Depending on version, from mid-2019 it will be possible for the rear seats to be moved by 14cm and for the backrest to be folded into a steeper position to vary the capacity of the luggage compartment behind the rear seats between 455 and 705 litres.

With the rear seat folded down and luggage loaded to the roof, the luggage compartment, which is flat thanks to the adjustable load compartment floor, can accommodate up to 1540 litres behind the front seats. A folding backrest of the front passenger seat (optional extra, expected to be available from mid-2019) makes for an even longer loading length.

The new B-Class comes with driving assistance systems from the S‑Class. For the first time, the B-Class is able to drive semi-autonomously in certain situations. To do so, it employs improved camera and radar systems to anticipate the traffic up to 500m ahead while using map and navigation data for assistance functions. For example, Active Distance Assist Distronic as part of the Driving Assistance package is able to support the driver in many route-specific situations, predictively and conveniently adjusting the speed. Also on board are Active Emergency Stop Assist and intuitively understandable Active Lane Change Assist.

The new B-Class comes as standard with extended Active Brake Assist, which can help mitigate the severity of rear-end collisions with slower-moving, stopping or stationary vehicles ahead – and now even with crossing pedestrians or cyclists – or prevent them altogether.

Five engine variants will be available at the launch of the B-Class. The most efficient is the 180 d with 116PS. It can achieve up to 68mpg and emits from 109g/km of CO2.

The most powerful is the 220 d with 190PS. There is also a mid-range 200d with 150PS.

Petrol models consist of a 180 and 200 with 136PS and 163PS respectively.

All models feature an automatic transmission.
