Under the microscope: Mercedes-Benz B 220 d: Clean début

The OM 654q in the B 220 d (combined fuel consumption: 4.5-4.4 l/100 km; combined CO2 emissions: 119-116 g/km)[15] is the first four-cylinder diesel engine to comply with the Euro 6d standard, which does not come into effect until 2020 for new models. An expanded near-engine emission control system with an additional underfloor SCR catalyst makes this possible.

Even in demanding driving situations and under challenging environmental conditions, the B-Class remains within the emission limits. This is achieved by additional selective catalytic reduction (SCR) with an ammonia slip catalyst (ASC) in the exhaust system of the B-Class. This allows a more generous dose of the reduction agent AdBlue®, as any surpluses can be reduced and converted in the SCR. These surpluses (ammonia slip) particularly occur during fast temperature changes in the exhaust tract, e.g. when moving from city traffic to the motorway.

Despite having a lower displacement than its predecessor, reduced to just under two litres, and weighing around 16 percent less, the new diesel powerplant in the B 220 d has an output of 140 kW (190 hp), precisely 10 kW more than the previous engine, and delivers an NEDC combined consumption of 4.2 litres per 100 kilometres.

The new B-Class: More Sports for the Tourer

The new Mercedes-Benz B-Class looks more dynamic than its predecessor and is more agile on the road while offering greater comfort and more space. Apart from the OM 654q engine from the two-litre diesel model series adapted for transverse installation, the dual clutch transmission with eight gears is also celebrating its premiere. The avant-garde interior of the B-Class ensures a unique feeling of spaciousness with the distinctive design of the instrument panel.

The intuitive user interface of the adaptive MBUX multimedia system is ground-breaking. Its strengths include brilliant graphics, "Hey Mercedes" voice control, a standard touch screen and functions such as MBUX Augmented Reality. State-of-the-art driving assistance systems give the B-Class one of the highest standards of active safety in the segment with functions carried over from the S-Class. Since 3 December 2018, the new B-Class has been available to order and is being delivered as of February 2019.
