Mercedes fans the diesel flames

The 2011 Mercedes-Benz ML350 Bluetec is the kind of SUV some people will love and others won’t … simply because of its diesel engine.

I’ve always been a fan of diesels, even when their driveability, noise and emissions were a bit of a compromise. But with today’s quieter, clean-burning diesels more and more people are discovering they love the one-two punch of power and fuel economy that knocks gasoline-powered rivals out of the ring.

While the new M-Class is available with a choice of engines – right up to a 6.2-litre, 503-hp gas-powered V8 in the ML63 AMG – our test vehicle has the Bluetec diesel, with AdBlue injection for even lower emissions. It’s becoming the engine of choice for more and more buyers – in the U.S. (finally!) as well as in Canada.

Like so many modern vehicles, the ML350 features keyless entry and ignition. Even with the diesel engine the ML350 fires up almost instantly – unless it’s really cold. When the temperature dips below -15C it may take a second or two before ignition occurs. That’s not a long time to wait for those of us old enough to remember when a diesel engine’s glow plugs would have to be activated for what seemed an eternity before the air-fuel mix was warm enough to burn.

Diesel cabins also used to take a notoriously long time to warm up, but there’s no such problem with the ML350 Bluetec. Heated air quickly flows from the vents, even on sub-zero days, and the three-position heated front seats will have you feeling toasty in no time. Because our tester has the optional $6,700 Grand Edition package, the seats and dash are covered in man-made Artico leather, which has been criticized for not smelling like the real thing.

The 3.0-litre turbocharged diesel doesn’t produce as much horsepower as the ML350’s available 3.5-litre gasoline V6 – 210 hp vs. 268. But it’s an engine that makes the vehicle sneaky fast – capable of going from 0-100 km/h in 8.7 seconds.

As well, there’s the tremendous torque advantage a diesel always has with 400 lb.-ft. available in a useful range from 1,600 to 2,400 rpm. This gives it the low end grunt to break free in deep mud, sand or snow plus a towing capacity of 3,625 kg. The full-time 4Matic all-wheel drive also provides excellent control over all kinds of surfaces, aided by a four-wheel electronic traction system.

The ML350 is built to deliver a quiet ride, and extra noise insulation also means the diesel’s typical clatter is not heard inside the passenger compartment.

Shifts are exceptionally smooth, thanks to a seven-speed automatic transmission that selects gears directly for uninterrupted delivery of torque. Paddle shifters on the steering wheel allow the driver to choose gears manually.

The sophisticated, low emissions engine delivers exceptional fuel economy for this class of SUV – 9.8 L/100km in our real world test – and the ability to stretch a tank of diesel well past the 1,000 km range.

The smoothness of the drivetrain is matched by the way the ML350 glides over the road, courtesy of an air suspension system that automatically lowers ride height at highway speeds. As well, the driver can manually choose from three damper settings – auto, sport and comfort depending on how aggressively he/she wants the vehicle to perform.

The seats are terrific but, unlike traditional M-B practice, the power controls are not on the doors. They’re positioned on the outside of the seat-bottom frame, like most everyone else.

The ML350 is strictly a five-passenger vehicle, with a rear seat that’s split 1/3 to 2/3, not the usual 60/40. Cargo capacity with the seats upright is a generous 833 litres which expands to 2,050 with the second row fully lowered.
