BMW's Sports Activity Vehicle, the X5, will receive a complement of design and engine changes to refresh the line since launch in January 2007.

The new BMW X5 includes a number of subtle exterior changes, but enhancing the athletic appearance of BMW's original 4x4. Revised front bumpers with enlarged vents, to increase the air supply to the engine and brakes, and matte aluminum-look lower scuff plates and vent fins, now feature to underscore its performance credentials.

New xenon headlights, with bright white LED corona rings, modernize the face of the car whilst the more centralized front fog lights complete the new front end. At the rear is a revised red light cluster, enhancing the lines of the car with horizontal LED light bars. Enlarged tail pipes, within a redesigned rear bumper, finish off the look.

Three new engines will be launched for the xDrive30d, xDrive40d replacing the xDrive35d and the xDrive50i replacing the xDrive48i. All of the new powerplants now meet EU5 standards.

The entry level xDrive30d has been upgraded to provide increased performance, making this the first conventionally-powered luxury SAV to record a sub 200g/km CO2 reading. According to official figures, The engine consumes just 38.2mpg on the combined cycle and emits only 195g/km of CO2 a 10 per cent improvement yet produces 245hp, up 10hp on the previous xDrive30d. Acceleration to 100km/h now takes only 7.6 seconds a six per cent improvement over the previous model.

The replacement of the twin-turbocharged xDrive35d with the new xDrive40d sees an improvement in emissions of 10 per cent, emitting only 198g/km CO2 whilst delivering 37.7mpg on the combined cycle. In true EfficientDynamics style the performance of the car has also increased. The zero to 100 km/h time is now just 6.6 seconds, down from 7.0 seconds, courtesy of a 306hp output, 20hp more than the outgoing engine.

Powered by the world's first twin-turbocharged V8 engine with a relocated catalytic converter, the xDrive50i has an extra 53hp compared to the model it replaces, taking the total to 408hp. This leads to a lower zero to 100km/h time of 5.5 seconds, an improvement of 1.0 second over the outgoing powertrain.

The BMW X5 will also be mated to a standard eight-speed automatic transmission. This transmission helps to lower the X5's CO2 output and allows smoother shifting and greater driving dynamics.
