Mercedes M-Class

Take a look at Mercedes' new luxury 4x4! These are the first spy shots of the new M-Class which is set to go on sale in 2011 – and when it does it'll be one of the most efficient SUVs you can buy.

Judging from these exclusive images, the new M-Class won't be any bigger than the current car – and, in fact, our sources reckon it could actually be a little smaller. There will be a huge focus on reducing weight too, while under the bonnet the new M-Class will be available with a plug-in hybrid powertrain from launch.

As you can see the looks won't change that much, although expect the newcomer to be a little sleeker and less aggressive. In addition to a hybrid powertrain, expect a wide range of diesels offering between 190bhp and 306bhp. Range-topping models will still be available with large petrol engines too. We'll see the new M-Class at a major motor show next year.
