Good to the bone

Would it be hokey to say that the redesigned Mercedes-Benz M-Class is the very template that every luxury SUV should follow?

If it is, get used to it, because there’s plenty more gushing where that came from, as this is simply one of those vehicles that is a pleasure to be inside, whether you’re the driver or a passenger.

Though there are four very well-equipped models from which to choose (ML320, ML350, ML550, ML63 AMG), this week’s tester is the diesel-powered ML320 Bluetec.

One could argue that the diesel model is the best of the four M-Class SUVs, thanks to the ace up its sleeve in the form of excellent fuel economy.

The M-Class has been a perennial favourite of critics since its inception for the 1998 model year, earning all kinds of accolades. It wasn’t until the 2007 model year that North America received a diesel model, while 2009 sees the M-Class diesel get Bluetec technology, a system that helps reduce diesel emissions, making models equipped with this technology some of the cleanest-burning diesels in the world.

Being more environmentally-friendly than previous diesel vehicles is just the tip of the iceberg in terms of what makes the ML320 such a superb SUV. Standard safety features on all M-Class SUVs include six airbags, PRE SAFE system (which gauges the possibility of a crash and takes action such as cinching seatbelts and closing open windows or sunroof), brake assist, ABS brakes and traction control. It gets some decent off-roading goodness in the form of generous ground clearance, 4MATIC all-wheel drive and downhill speed regulation (plus, the pictures in the brochure show it on top of cliffs and rocks and stuff!).

Luxury features, meanwhile, are truly what make the ML320 so wonderful to drive - from the supple leather seats and optional Harman/Kardon surround sound system (still the best stock sound system as far as we’re concerned) to the automatic climate control and adaptive air suspension damping system. That last feature automatically lowers ride height when you gain speed, which results in improved handling and less drag for lower fuel consumption.

Each M-Class SUV is equipped with a different engine, with the ML320 model getting a turbocharged V6 with 3.0-litre displacement. It has a ridiculous amount of torque to get it moving - just be patient, as turbo lag and a two-and-a-half ton curb weight combine for a noticeable delay before this SUV takes off. It’s difficult to hear the diesel engine’s throaty chugging sound (or any other noise coming from the vehicle or anywhere else) because the ML320 is so well-insulated.

There’s lots of room to fit larger items in the rear cargo area, and it’s great to see that Mercedes recognizes that luxury SUV drivers still need things like hooks and smaller storage compartments for groceries and other everyday objects. The 70/30 split rear seats fold almost-flat and can be manipulated with one hand. If all you have is a finger or two available because of two arms full of cargo, an optional power liftgate makes life even easier.

The best we can come up with in terms of annoyances is the optional multimedia interface. First - it should be standard. Second - the outlets are placed at the very back of the glove box, making it extremely awkward to get access to and set up. It would be great if Mercedes employed a touch screen for navigation, sound, etc. Using countless buttons is cumbersome at best.

The M-Class makes its presence known thanks to a magnificent redesign that will literally have people stopping in the middle of the street to give it a closer look. This vehicle exudes greatness, but that excellence is far from just skin deep.
