Just over a month after the unveiling of the new G20 BMW 3 Series, Munich has released details on the plug-in hybrid version, the 330e. The new petrol-electric variant gets various improvements to performance and efficiency, on top of all the new features of the standard model.

Continuing to provide motivation is a 2.0 litre turbocharged four-cylinder petrol engine, again producing 184 hp – the same as a 320i. The electric motor, integrated into the eight-speed ZF automatic transmission, produces a constant 50 kW (68 hp) but, more importantly, generates peak output of 80 kW (109 hp).

All in all, the powertrain develops a total system output of 252 hp and 420 Nm of torque. That’s the same as the outgoing model, but for the first time there’s now an XtraBoost feature that delivers an extra 30 kW (41 hp) of accelerative boost. This brings the total amount of available power up to 292 hp, accessible via the Sport driving mode, under kickdown and in the gearbox’s sport and manual modes.

Performance figures include a zero-to-100 km/h sprint time of 6.0 seconds (0.1 seconds faster than before) and a top speed of 230 km/h (up 5 km/h). Meanwhile, the car delivers a fuel consumption figure of 1.7 litres per 100 km and carbon dioxide emissions amounting to just 39 grams per kilometre – numbers that are down by more than 10% over the outgoing model.

Juicing the electric motor is a 12.0 kWh lithium-ion battery that allows for nearly double the pure electric range, at 60 km. It will also travel in this mode at speeds of up to 140 km/h – 20 km/h up on before. The battery sits under the rear seats, reducing boot space from 480 litres to 375 litres, though you can increase the amount of cargo you can carry by folding the 40:20:40-split rear seats.

As usual, the 330e comes with virtually all the options of the standard 3 Series. Available in standard, Advantage, Sport Line, Luxury Line and M Sport trim levels, it is offered with features such as adaptive M suspension, Variable Sports Steering, an M sports braking system, Driving Assistant Professional with steering and lane guidance, and Parking Assistant with the new Reversing Assistant feature.

Features unique to the 330e are the standard interior pre-heating and air-con pre-conditioning as well as new digital services to be prepared in time for the car’s market launch in the summer. These include the suggestion of nearby hotels, restaurants, cafes and other attractions when selecting a charging stations, information on station availability and station occupancy forecasting, and the reservation of selected stations.
