BMW has unveiled its second-generation X3 mid-size Sport Activity Vehicle (SAV), first launched in 2010. The new BMW X3 is available from launch, depending on market, with a choice of four diesel and three gasoline engines, with outputs ranging from 110 kW/150 hp to 230 kW/313 hp. Among the X3 engine range, a new 2.0-liter diesel unit producing 140 kW/190 hp is making its world premier in the X3 xDrive 20d.
The new generation of all-aluminium 2.0-liter diesel engines uses common rail direct injection with solenoid valve injectors and works with increased injection pressure of 2,000 bar. This pushes the output of the X3 xDrive20d from 135 kW/184 hp up to 140 kW/190 hp, with the maximum torque available also rising from 380 to 400 N·m (280–295 lb-ft).

This increase in performance cuts the car’s 0 to 100 km/h (62 mph) acceleration time by 0.4 seconds to 8.1 seconds. At the same time, the fuel consumption of the X3 xDrive20d with eight-speed automatic gearbox drops by 7.1% compared to the outgoing model, and CO2 emissions are down to 141–138 g/km.
Fourth-generation reduced-rolling-resistance tires cut CO2 emissions by a further 7 g/km, making a significant extra contribution to the environmental and economic performance of the new BMW X3.
Equipped with these tires, the BMW X3 xDrive20d delivers combined cycle fuel consumption of 5.0 liters per 100 kilometres (47 mpg US) with CO2 emissions of 131 g/km.
The new 110 kW/150 hp BMW X3 sDrive18d, with its classical rear-wheel drive, a six-speed manual gearbox and reduced-rolling-resistance tires, does even better and records the lowest fuel consumption (4.7 liters/100 km [50 mpg US]) and CO2 emissions (124 g/km) of any model in the mid-size Sports Activity Vehicle segment.
Depending on the engine variant specified, the new BMW X3 can be ordered with a sporty, precise six-speed manual gearbox or a highly effective eight-speed automatic,
The new X3 also the BMW EfficientDynamics package of Auto Start Stop function, Brake Energy Regeneration, Optimum Shift Indicator and on-demand operation of ancillary units. Other features contributing to the economical running of the new BMW X3 are the ECO PRO mode selectable via the Driving Experience Control switch and the coasting function of the eight-speed automatic gearbox, which disengages the powertrain at speeds of 50–160 km/h (approx. 30–100 mph) when the driver takes his or her foot off the accelerator.
