The new BMW X1 xDrive20d EfficientDynamics will achieve 62.8 mpg and 119 g/km CO2, becoming the cleanest and most economical BMW X product ever.
Powered by a 163 bhp 2.0-litre four-cylinder diesel engine, the car will attract a company car taxation band of only 13 per cent for business drivers.
TwinPower Turbo technology, which combines a variable geometry turbocharger and high-pressure fuel injection, gives maximum power at 4000 rpm, while peak torque of 380 Nm comes in at 1750 rpm and remains constant until 2750 rpm. A centrifugal pendulum absorber in the dual-mass flywheel damps out vibrations at low engine speeds, while new insulation technology eliminates engine noise inside the cabin.
The BMW X1 xDrive20d EfficientDynamics has Auto Start-Stop, Brake Energy Regeneration and an Optimum Shift Indicator adapted to suit the new engine’s characteristics. Electro-mechanical power steering, an air conditioning compressor, which can be disengaged, and tyres with reduced rolling resistance are fitted to Streamline-design light alloy wheels, all come as standard. The car also has a long final drive ratio to reduce engine revolutions at cruising speeds, but it still takes the car from zero to 62mph in just 8.3 seconds.
The BMW X1 xDrive20d EfficientDynamics starts at £25,715 when it goes on sale in September 2011.
