The BMW 2 Series Active Tourer plug-in hybrid prototype
fuses BMW eDrive with a model-specific form of power transmission – based on the front-drive concept of the standard BMW 2 Series Active Tourer – which sees action for the first time. Following on from the four-cylinder petrol engine in the BMW 3 Series plug-in hybrid prototype, a front-mounted transverse three-cylinder petrol unit from the new Efficient Dynamics engine family now forms part of a plug-in hybrid system for the first time.
The 1.5-litre BMW TwinPower Turbo engine generates an output of 100 kW/136 hp together with a peak torque of 220 Nm (162 lb-ft), with power relayed to the front wheels via a six-speed Steptronic transmission. The additional high-voltage generator on the front axle fulfils three different tasks: it boosts the combustion engine for brief periods with extra output of up to 15 kW and some 150 Nm (111 lb-ft) from rest, generates electric power while on the move (which is fed directly to the high-voltage battery), and enables the engine to be started and turned off very smoothly thanks to its higher output compared to conventional starters. The electric motor is located above the rear axle, together with its two-speed transmission and the power electronics. It sends output of up to 65 kW/88 hp and maximum torque of 165 Nm (122 lb-ft) through the rear wheels.
The on-demand, road-linked all-wheel drive provides qualities unmatched in this segment, with the power electronics distributing drive to the front wheels, rear wheels or all four wheels as required. As with the BMW i8, the intelligent drivetrain management and networking with the DSC (Dynamic Stability Control) system ensure safe and supremely assured handling characteristics at all times, together with optimised traction, highly dynamic acceleration and cornering, and maximum efficiency.
The BMW 2 Series Active Tourer plug-in hybrid prototype accelerates from 0 to 100 km/h in around 6.5 seconds. Its average fuel consumption in the EU test cycle for plug-in hybrid vehicles will be approximately two litres per 100 kilometres, which equates to CO2 emissions of under 50 grams per kilometre. The range on electric power alone as measured in the EU test cycle will be 38 kilometres.
The pricing for the production version of the BMW 2 Series Active Tourer with plug-in hybrid drive has not yet been finalised. But thanks to its specific overall vehicle concept, prices at launch will be in the range of existing engine variants with comparable power outputs – just as they are for the electrified versions of the BMW X5 and BMW 3 Series. This means that customers do not have to pay a high premium for the technology.
