Back in 2007, the BMW 1-Series set a new global benchmark, with a unique range of technologies to reduce fuel consumption and emissions being included as standard. Today, the new BMW 1-Series extends the scope of the BMW EfficientDynamics programme. The diesel versions have a centrifugal-force pendulum built into the dual-mass flywheel to compensate for rotational irregularities and ensure a smooth ride at low revs.

The car makes extensive use of intelligent energy management systems, including Brake Energy Regeneration and electromechanical power steering. Depending on the model, these may also include a gear shift indicator, automatic air valve control, a high-efficiency rear differential, a map-regulated oil pump, a pressure/rev-regulated electric fuel pump, a self-disconnecting air-conditioning compressor and tyres with reduced rolling resistance.

The Automatic Start/Stop function, which switches off the engine when it is stationary at traffic lights or in slow-moving traffic, is included as standard in the new BMW 1-Series, with both manual and automatic transmissions. ECO PRO mode, which is activated by the driving experience switch, adjusts the engine map, heating, air conditioning, and mirror/seat heating to minimize fuel consumption. The resulting increase in range is shown on a display.

As a result, the new BMW 1-Series will embody the concept of fuel-efficiency like no other premium car, building on the strengths of its predecessor in this area. At a later date, the range will be expanded with the BMW 116d EfficientDynamics Edition. This will be powered by a 1.6-litre diesel engine, and feature a number of fuel-saving and emission-reducing technologies, including solutions to further optimize drive-train efficiency, improve aerodynamic performance and reduce rolling resistance. The BMW 116d EfficientDynamics Edition will have an output of 85 kW/116 hp, with fuel consumption of 3.8 litres per 100 kilometres and CO2 emissions of 99 grams per kilometre over the EU combined cycle (provisional figures).
