Mercedes-Benz M-Class

The latest generation of the Mercedes M-Class was introduced in late 2011 as Mercedes lifted its game against rivals that have emerged in the decade since it spawned this segment: the Audi Q7, Porsche Cayenne and BMW X5. The M-Class is nearly four-metres long and has a massive load area, regardless of which of model you choose. The ML 250 starts the range with a 202bhp 2.1-litre four-cylinder turbodiesel, then there's the volume-selling ML 350 with its 255bhp V6 turbodiesel. If it's power you’re after rather than efficiency, there's the ML 63 AMG complete with 518bhp 5.5-litre twin turbo V8 – the most powerful Mercedes 4x4 ever sold. All offer luxurious equipment levels, fit and finish as well as an imposing road presence.

The M-Class offers a lot of choice when it comes to engines and chassis: the ML 250 offers great efficiency for such a well-equipped, large car, while the ML 350 adds more power as well as the more comfortable air-suspension. Of course, the ML 63 is the fastest of the range, with so much power that its acceleration figures can match many performance saloons. Even the lightest version of the ML is more than two tonnes, yet the M-Class doesn’t feel as heavy as you’d expect. There's modest power from the ML 250, with a supercar-like 518bhp from the ML 63. The steering is well weighted, making it easy to position on the road and the M-Class is surprisingly easy to manoeuvre around town and in tight spaces. All models have Park Assist, too, which automatically reverse-parks for you and makes the M-Class even more urban-friendly.

Cabins don’t get much better than this, especially for the money. The M-Class has excellent leather seats which are comfortable and supportive, with a heap of adjustment as well as heating and cooling. There are superb finishes, great materials and solid-feeling switchgear while the dash layout is clear. One useful option is the Comand system, which controls the sat-nav and stereo, while the optional panoramic glass roof brightens up the cabin. Optional rear-headrest displays and multi-zone air-con with rear controls (dual-zone is standard) are available, too. If you’re after a plusher ride, there's air suspension available as well. Our only real gripe is that for such a large car rear legroom could be better to make it more comfortable.

The M-Class has come a long way since its introduction, where the US-built 4x4 was hampered by build quality problems. The maturing of the segment has seen rivals such as Audi and BMW force Mercedes to lift its game to remain competitive, so the ML is a much more reliable car than before. The 2.1-litre is also fitted in the C-Class and E-Class saloons, so will benefit from software and servicing improvements garnered from the popular saloons. Warranty is three years with unlimited mileage.
