The carmaker claims the model’s distinctive styling will make it appeal to a different buyer to the existing X3 and X6 models.
It is aimed at those who like the driving position of an SUV, but want to combine it with the on-road performance of a sports car.
To demonstrate its sports car attributes, for the first time in BMW’s history the entire model range will be equipped with turbocharged engines.
At the launch, the X6 will be available with a choice of two six cylinder diesel units, plus the award-winning 3.0 litre twin-turbocharged petrol from the 1 and 3 Series models.
Prices for the diesel models, which BMW expects to be the most popular in the UK, will be £41,995 OTR for the single turbocharged 235bhp engine and £44,135 for the twin turbocharged 286bhp engine.
The twin turbocharged petrol will cost £42,625.
The fourth, and most powerful, model will be powered by an all-new twin turbocharged 4.4 litre V8, and is expected to join the range later in the year.
The 408bhp unit makes the X6 xDrive50i the most powerful X car on offer, capable of propelling the X6 to 62mph in just 5.4 seconds and onto an electronically limited 155mph.
Prices have yet to be announced.
