Mercedes-Benz M-Class

Previous Ms had severe slabbiness and handling flabbiness; this new one is eco happiness.

• Comfort

  If there's one thing the last M did well, it was comfort. This one's no different, and it now has active anti-roll bars - an optional extra - to help it ride even better by reducing choppiness over lumpy roads. You're better off choosing this over the optional active ride system, because it's more useful more of the time, and you can sense it smoothing out the tarmac.

  

• Performance

  The entry level ML 250 CDI is a 2.1-litre four-cylinder diesel engine. It's not as effortless as the350 CDI V6 diesel, but 204bhp is just enough to shift the considerable mass around without running out of breath. 0-62mph takes nine seconds, and you'll top out at 130mph. The 350 though is a peach; 255bhp and a mass of torque makes light work of the heavy Merc.

  

• Cool

  If you're a footballer's wife then they probably look quite attractive, but the truth is that you can go cheaper and have as much space and prestige.

  

• Quality

  Unlike early M-classes, the new one feels very solid. There's a fabulous feeling that Merc has started spending money on the bits that matter - and a decent interior is very important in this sector.

  

• Handling

  A Porsche Cayenne or BMW X5 both drive much better, but the ML rides well and manages to get around corners without falling over. The ride compromise is more comfort-orientated, and you'll never forget that this is a tall SUV from the old school. If you want to get muddy, then you need the ‘Off-Road pro' option pack. But then you'd look a bit try-hard.

  

• Practicality

  Obviously the five-seat ML is a little bit smaller than the seven seat GL, but it manages to feel spacious, comfortable and practical (with no messy gear selector in the centre). 

  

• Running costs

  The ML 250 CDI releases 158g/km of CO2. Really. Couple this with 43.7mpg and you've got yourself something quite economical. Quite.
