For 2005, there are only two M-Class models to choose from, the ML 350 with a brand-new four-valve-per-cylinder 3.5-liter V6 engine, and the ML 500, with the tried-and-true three-valve-per-cylinder, twin-spark 5.0-liter V8. (Later on, there will be an additional high-performance model using an AMG V8 engine, probably the new 6.3-liter naturally aspirated V8 they're working on. In calendar year 2007, the new 3.2-liter diesel V6 will be added to the ML lineup.)Both gas engines come with a seven-speed automatic transmission (called the 7G-Tronic). All models also come with the next generation of Mercedes-Benz's full-time, brake-based 4ETS electronic all-wheel-drive and traction control system.
With either engine, the package of standard equipment is staggering. After all, this is a Mercedes-Benz, and they don't stint on power, luxury, or entertainment equipment in these trucks. They tried that on the first ML, customer reaction was negative, and they won't do that again.
Mercedes-Benz's renowned commitment to occupant safety means that the 2006 M-Class comes standard with ABS, ESP stability control, traction control, two-stage adaptive airbags for the driver and front passenger, curtain side airbags and adaptive belt tensioners and belt force limiters for all seating positions.
