BMW has released information on the latest version of its best-selling SUV, the X5. There will be four engines to choose from (two petrol and two diesel) as well as a smorgasbord of technological and aesthetic changes, including the introduction of an eight-speed automatic gearbox.

The top of the range X5 xDrive50i will be powered by a twin-turbo, direct injection V8, with an output of 407bhp, while the entry-level xDrive30d is thought to be the most popular. The other versions will use V6 engines (one petrol, one diesel), which each boast twin-turbo and direct injection. Power outputs for both these engines sit at 306bhp, while the new xDrive40d has 442lb.ft of torque at its disposal - to the xDrive35i's 295lb.ft.

Visually, the new 2010 X5 is distinguished by banks of LED lights on the front and rear of the car, along with larger side air intakes, a reshaped rear bumper and revised tailpipe surrounds.

On the inside, the driver has access to the latest iDrive system, which deals with the navigation, audio and communication amongst others. Customers can also specify the 'Professional' spec iDrive that has an MP3-compatible CD player and aux-in connection, as well as an optional DVD changer and entertainment system.

As is fashionable with modern day luxury 4x4s, the X5 gets endowed with a range of safety features. These include Park Distance Control, High-Beam Assistant and Adaptive Headlights as standard. Customers can then specify options such as adaptive cruise control and Lane Departure Warning.

We expect details like pricing for the X5 to be announced nearer the release date, speculated to be this summer following a likely debut at next month's Geneva Motor Show.
