Last updated 26 November 2017

More spacious and economical than before. High quality and comfortable interior. Great motorway cruiser. Impressive refinement.
ML 250 CDI engine can feel sluggish. 7G-Tronic gearbox not quick to respond. Poor in corners.

The previous Mercedes-Benz ML proved a big hit for the German brand with its good looks and strong engines. So it's no surprise to see much of the same with this latest model. There are some significant improvements under the body with the engines being overhauled to provide better fuel economy but with minimal changes to performance.

As a result the entry-level ML300 CDI has been replaced with a new four-cylinder 2.2-litre engine that produces the same power and torque as the outgoing model, but with fuel efficiency improved from 33.6mpg to 47mpg. The trade off is that it's a fairly noisy engine that lacks the refinement of its predecessor although this is less noticeable on motorways. The ML is at its best with the ML 350 BlueTEC which is more powerful than the previous ML 350 CDI with more torque yet is also more economical.

The ML is most at home on the motorway where you can cruise along with little wind or road noise. Refinement and ride quality are both very impressive. Unfortunately it's not as good in corners. The steering is slow and there's plenty of bodyroll so it doesn't give you much confidence. That said grip is good and thanks to the permanent four-wheel drive system there's plenty of traction.

The improvements continue inside with a much better cabin both in terms of quality and on-board technology. The buttons and switches have a better quality feel to them and there's a much improved colour screen mounted in the central dash. It certainly has a premium feel that's on par with its rivals like the BMW X5. The large boot and spacious back seats make it a good family car.

Owners' reviews

Luxury in abundance, and superbly relaxing to drive.
Lots going for it, but proved to be disappointing.....
So far so good.
So far so good, it does everything brilliantly.
Not a German made car
