Offering a substantial enhancement of driving pleasure and economy, the BMW X3 is set to further broaden its leading position in the 2008 model year as the world's most successful Sports Activity Vehicle (SAV).
A newly developed four-cylinder diesel engine in the BMW X3 2.0d and numerous fuel-saving improvements on all model variants give this five-door widely lauded for its superior agility and driving dynamics best marks in its segment now also in terms of efficiency. A further point is that the new BMW X3 2.0d is now also available not just with a six-speed manual gearbox, but also with six-speed automatic transmission offering optimized gearshift dynamics. And entering the 2008 model year, the BMW X3 is gaining even greater appeal through the introduction of crash-activated headrests as a standard feature as well as new options and paintwork colors.
Developing maximum output of 130 kW/177 hp and maximum torque of 350 Newton-metres/258 lb-ft, the new BMW X3 2.0d offers a significant increase in power and pulling force. Average fuel consumption in the EU test cycle, however, is a very modest 6.5 litres/100 kilometres, equal to 43.5 mpg imp. The gasoline engine variants also offer further enhancement of efficiency in the 2008 model year, the 200 kW/272 hp BMW X3 3.0si now making do with just 9.5 litres/100 kilometres, equal to 29.7 mpg imp.
These optimized fuel consumption and emission figures are the result of the latest innovations based on BMW EfficientDynamics now also being introduced in BMW's Sports Activity Vehicles. Thanks to these improvements and the outstanding competence of BMW in the development and production of power units, a four-cylinder diesel is now able to offer the same standard of dynamic performance in a larger vehicle only a six-cylinder - at best - was able to provide in the past, while at the same time retaining all the advantages of a four-cylinder in terms of fuel efficiency.
By analogy, BMW's current six-cylinders likewise rank right at the top in their segment in terms of both fuel consumption and emissions, even though they provide all the power and performance of an eight-cylinder. New four-cylinder diesel: output up 20 kW/28 hp, fuel consumption down 10 per cent.
Entering the 2008 model year, the BMW X3 fitted as standard with BMW xDrive intelligent all-wheel-drive technology is available with three ultra-modern gasoline and diesel engines. The absolute pinnacle in terms of efficiency is the new BMW X3 2.0d, its all-aluminium four-cylinder diesel featuring third-generation common-rail fuel injection, with fuel being dosed by piezo-injectors and injected into the combustion chambers with absolute precision under a pressure of 1,800 bar.
Compared with the former engine, the new four-cylinder diesel offers an increase in power by 20 kW or 28 hp on a reduction in fuel consumption by 10 per cent. And at the same time the new BMW X3 2.0d establishes a new benchmark not only in fuel economy, but also in CO2 emissions, with 172 grams per kilometre setting a new standard in this segment.
The refinement of the entry-level model leading into the BMW X3 family has also been improved. To reach this objective, the balance shafts for the four-cylinder diesel take the specific layout and the space available in an all-wheel-drive vehicle into account, the two balance shafts running in needle bearings against the engine's direction of rotation being fully integrated at the side in the crankcase. This position makes the integration of balance shafts possible also on the BMW X3 equipped with xDrive.
