The range of diesel engines for the new BMW X3 are available with four or six cylinders and are both powerful and economical thanks to BMW EfficientDynamics and BMW TwinPower Turbo technology. One of the many highlights is the latest-generation four-cylinder diesel engine in the BMW X3 xDrive20d, which produces 140 kW (190 hp) with fuel consumption of just 45 to 47 mpg and CO2 emissions of 137 to 130 g/km.* In addition, all engines fulfil the EU6 emission standard that comes into effect in 2014.
All figures in accordance with EU test cycle and dependent upon the selected tyre format.
* Fuel consumption is determined in accordance with the ECE driving cycle, made up of approximately one-third urban traffic and two-thirds extra-urban driving (based on the distance covered). CO2 emissions are measured in addition to fuel consumption. Further information on the official fuel consumption and on the official specific CO2 emissions of new automobiles can be found in the guidelines on fuel consumption and CO2 emissions of new automobiles (see http://carfueldata.direct.gov.uk/
). The figures for fuel consumption and CO2 emissions apply in conjunction with the equipment selected.
 Rated output: BMW recommends the use of super unleaded 95 RON fuel. Unleaded RON 91 fuel or higher with a maximum ethanol limit of 10 percent (E10) is also permitted. The performance and fuel consumption rates listed are based on the use of RON 98 fuel.
