The front stabilizer bars have been made bigger on the 2002 M-Class, which features a double-wishbone, four-wheel independent suspension. Our ML500 provided a ride that was smooth, steady, firm and never jarring. The handling is extremely good for an SUV this heavy; it follows aggressive steering commands without fuss, and the beefy tires are grippy. A driver can feel the weight if he or she yanks the steering wheel, however, and it will lean some in emergency lane change maneuvers, but it's prone neither to pushing at the front end (understeer) nor sliding at the rear (oversteer). Of course, the magical Electronic Stability Program controls this loss of traction during cornering, particularly on dirt, gravel or slippery pavement. ESP applies brakes to individual wheels to help turn the vehicle evenly whenever it detects a skid. It too has been revised in 2002, to give a more rapid response.
The biggest problem with the handling might be the inconvenience of the heavy steering. At slower speeds the steering effort is very high, and women may not like this. You might even find yourself turning wider than you intended to, because you didn't muscle it enough. A weak-shouldered driver will have to watch it as they turn into a shopping-center parking space.
The anti-lock brakes, with massive discs, ventilated in front, are impressive, and the pedal feel is as solid as the rest of the truck. The ML500 slows quicker than almost any other SUV made.
The M-Class lacks a hand brake or locking differential, two pieces of hardware that experienced off-road drivers sometimes rely on. But with 8.7 inches of ground clearance, the M-Class is capable of traversing terrain that few SUV buyers are likely to challenge. A switch on the dash triggers low range for the full-time four-wheel-drive, allowing the vehicle to creep up and down seriously steep inclines. Meanwhile, the electronic power distribution delivers grip in mud, snow, or uneven ground. The electronics apply the brakes on wheels that are slipping, and then send most of the power to those that are gripping. The M-Class can creep forward even if only one wheel has a bit of traction.
The ML500 performs so well, its ride and handling so solid, that only the wealthiest, hard-core, high-performance buyers will feel a need for the image-heavy ML55 AMG. It can accelerate from a standstill to 60 mph in 6.4 seconds. That's quick, but that will cost you another 21 grand. The engine is poked out to 5.5 liters, yielding 342 horsepower and a humongous 376 foot-pounds of torque. We drove a 2001 ML55, pushing it harder because it will be driven very aggressively by buyers, and found that the most fun you can have with it is staying in second gear and driving hard through twisty sections, listening to the rise and fall of the engine's deep Benz growl. The ML55 has a 25-gallon tank, by the way. It needs it.
Suspension and shock absorber changes make the ML55 lower than the ML500, which helps the center of gravity, and super-wide 285/50R18 Dunlop tires provide awesome grip. And for 2002, the ML55 has larger front and rear stabilizer bars than it did in 2001. But it's still a truck, not originally intended to do the things it's modified to do. The car builders at AMG might be brilliant, but they're not miracle workers. Making a tall box like the M-Class feel like much more than a modified tall box may be beyond mechanical expectations. Still, the suspension changes keep it from leaning, which is good, except now there's not much warning that you're cornering too fast, except from your own brain. Which might not always be enough.
