Following the debut of the X3 Sports Activity Vehicle at the Frankfurt Motor Show, BMW has revealed details of engine line-up, specifications and prices for the UK market.

At launch in spring 2004, the X3 will be available with either 3.0 or 2.5-litre petrol engines. Priced at £32,015 on-the-road, the 3.0i SE promises a maximum 231bhp, taking it from 0-62mph in 8.1 seconds and on to a top speed of 130mph, or 137mph for the 3.0i Sport model which also debuts at launch.

An impressive 300Nm torque is achieved at 3,500rpm with drive delivered through a standard 5-speed automatic gearbox. A manual gearbox will not be available on X3 3.0i models.

Joining the 3.0-litre launch models will be the 2.5i SE, priced at £28,615 on-the-road, together with the 2.5i Sport.

Powered by BMW's award-winning 192bhp six cylinder engine, the 2.5i develops 245Nm of torque at 3,500rpm. Its 6-speed manual box comes as standard; an optional 5-speed automatic is also available. Additional performance figures for the X3 2.5i SE and Sport will be confirmed closer to launch.

BMW managing director Jim O'Donnell said: "The new X3 represents the latest in a line of segment-defining vehicles from BMW. It is the first premium Sports Activity Vehicle in the compact/mid-size sector, and its appeal is already reflected in advance orders for much of next year's allocation a full eight months before the UK launch.

"I expect the X3 to be another benchmark to which our competitors aspire.'

All models in the X3 range feature BMW's brand new four-wheel drive system, xDrive. xDrive distributes drive to the axle, improving stability, driving pleasure and safety.

The system uses an electrically activated multiple-plate clutch which means it can respond more quickly than more conventional systems, which require the build-up of hydraulic pressure.
