Mercedes-Benz has launched the B 250 e plug-in hybrid, which is available to order now priced from £35,280.
Sharing a powertrain with the A 250 e, the newest addition to the B-Class line up has CO2 emissions from 27g/km and combined fuel consumption of 235mpg.
It uses a 1.3-litre petrol engine, which generates 158PS and 230Nm, with an additional 101PS and 330Nm available from the electric motor.
An electric range of 42 miles means the B 250 e falls into the 6% Benefit-in-kind tax bracket, meaning company car drivers can expect to pay from £12 per month.
There are three trim levels available, starting with the AMG Line Executive. Standard equipment includes: MBUX multimedia system with 10.25-inch display, privacy glass, heated front seats, climate control, 18-inch alloy wheels and parking sensors.
For an additional £1,500, AMG Line Premium adds a 10.25-inch digital cockpit, augmented reality for navigation, Keyless entry, ambient lighting and Mercedes-Benz advanced sound system.
The range-topping AMG Line Premium Plus adds a panoramic sunroof, Multibeam LED headlights, memory seats for driver and front passenger and Traffic Sign Assist. It costs £38,280.
The only standalone option for the B 250 e – available on AMG Line Premium Plus only – is the £1,495 Driving Assistance package. It includes a range of driver assistance systems, such as adaptive cruise control and lane keep assist.
