The BMW X5 (F15) is only three years old but the company is already working on the next-generation model which could be unveiled as early as next year.

Dressed in heavy camouflage, the redesigned crossover was recently spotted on the Nürburgring and is still in the early stages of the development.  As a result, there isn't much to see but we can make out a new hood and a revised front bumper with modified air intakes.


Little is known about the model but BMW Australia managing director Marc Werner recently confirmed the crossover will ride on the same Cluster Architecture (CLAR) that underpins the new 7 Series.  Thanks to a combination of lightweight materials such as aluminum and carbon fiber, the next-generation X5 could weigh between 220-440 lbs less than its predecessor.

Engine options remain a mystery but previous reports have suggested the X5 could come equipped with an assortment of different petrol and diesel units including a 3.0-liter inline six and an all-new V8.  There should also be a plug-in hybrid variant with an electric-only range in excess of 31 miles.

The fourth-generation BMW X5 is expected to be unveiled late next year before going on sale in 2018.
