Mercedes-Benz ML500 - Short Take Road Test - Car and Driver (blog)

The wide, flat torque curve (peak torque occurs from 2700 to 4250 rpm) provides prompt throttle response, and the tranny makes nearly transparent shifts. Still, that's a 0. 02-g improvement over that of last year's model, thanks to the single running-gear change--17-inch wheels and tires replace last year's 16-inchers. Mercedes, however, didn't see fit to change the ML's standard electronic stability program (ESP). When activated, it puts an end to any spin, but putting the dash-mounted ESP switch in the off position disables only the engine cutoff function and leaves the brakes to curtail slides. Both the ML320 and the ML500 have new front and rear bumpers, taillights, clear headlight lenses, and those 17-inch wheels. Other than badges, the only exterior differences between the ML500 and ML320 are the ML500's wider tires (275/55VR-17 versus 255/60SR-17) and chrome strips on the ML500's tailgate and door handles. The ML55 AMG's exterior is unchanged. Inside, this ML now has curtain airbags in addition to the front and side airbags, burled-walnut trim around the center console, and rotary climate-control.
