BMW has unveiled new plug-in hybrid systems at its annual ‘BMW Group Innovation Days’ event in Europe this week.

As part of the carmaker’s eDrive program, the new system will begin to make its way into BMW’s ‘mainstream’ models soon - starting with the updated 3 Series.

The system draws on current plug-in technologies used in the i3 and i8 models.

But while the i3 is available as all-electric or range-extended variants, the new eDrive system will be more of a ‘traditional’ plug-in hybrid in some models.

The 3 Series PHEV will feature a TwinPower turbocharged four-cylinder petrol engine, matched with an electric motor and an eight-speed automatic transmission.

On battery power alone, the 3 Series PHEV will offer a range of around 35km with a top speed of 120km/h.

Combined power and torque is listed as 180kW and 400Nm, with an overall fuel figure of just 2 l/100km and CO2 emissions of 50g/km.

BMW has also unveiled a 5 Series GT PHEV prototype to further demonstrate its new system, with a focus on maximising the input from the electric engine.

The German carmaker plans to improve its battery-powered engines to offer around two thirds of total power output in future models, while also boosting overall fuel consumption.

The 5 Series GT example shows the potential of such a plan with an impressive 500kW and 1017Nm in combined power, using just a 2.0 litre TwinPower turbocharged four-cylinder petrol engine and a pair of electric motors; one each for the front and rear axles.

A new 20kWh battery pack has been developed for the prototype which offers around 100km of electric-only range, and BMW’s confidence in the new system has prompted a much smaller fuel tank - 30 litres instead of 70.

While the petrol engine will usually act as a generator, it can be called upon to provide additional power to the front wheels under maximum acceleration.

Expect to see the new plug-in hybrid power plants in Rolls-Royce and up-spec BMW models, along with the updated 3 Series and X5 / X6 SUV siblings.
