Since the introduction of the Mercedes-Benz M-Class, many other premium automakers have entered the midsize luxury SUV market. Despite Mercedes' efforts, however, the original truck-based M-Class began to show its age against better-dressed and more refined car-based crossover SUV rivals. After eight years on the same aging platform, Mercedes finally reached for a much-needed clean sheet of paper for the second-generation M-Class, which debuted for the 2006 model year.

The latest M-Class is getting on in years, but it's still a roomy, powerful and luxurious SUV. It also boasts a remarkably high-quality interior and an unusual hybrid variant. There are many newer and cheaper competitors in the premium SUV segment, though, so it's worth looking around a bit before settling on a new M-Class. From a used-vehicle standpoint, versions of the current generation are still quite appealing, with first-generation models being less so.

Current Mercedes-Benz M-Class
The Mercedes-Benz M-Class is a five-passenger luxury SUV. Trim levels include the ML350 Bluetec with a 50-state-legal turbodiesel V6, the hybrid-powered ML450, the ML350 with a 268-horsepower 3.5-liter V6 and the ML550 with a 382-hp 5.5-liter V8. If you're looking to spice things up, you can also choose a fuel-slurping 503-hp ML63 AMG high-performance version. The diesel ML350 delivers 210 hp and 400 pound-feet of torque, doesn't cost too much more than the ML350 and promises highway fuel economy in the mid-20s. The ML450 Hybrid features a 3.5-liter V6, a pair of electric motors and an advanced transmission for a total of 335 hp

The M-Class SUVs come standard with full-time four-wheel drive (except for the base rear-wheel-drive ML350), automatic climate control, power-adjustable front seats, an older version of Mercedes' COMAND interface and a six-CD/DVD changer. A hard-drive-based navigation system with upgraded COMAND is optional. Available features across the lineup include an air suspension with adaptive damping, adaptive bi-xenon headlights, rear climate controls and a rear-seat entertainment system. The ML63 AMG adds unique styling elements and performance-oriented mechanical bits along with its larger engine.

In reviews, our editors have found that the current Mercedes-Benz M-Class imparts a feeling of solidity. With the optional air-spring suspension, the ride quality is impressively supple. Behind the wheel one will find plenty of room and excellent support from the premium multicontour seats, as well as superb cabin materials. Major downsides include fussy electronic controls, pokey acceleration of the V6 models and a price that's pretty expensive for the segment.

Used Mercedes-Benz M-Class Models
The current second-generation M-Class was introduced for 2006 in ML350 and ML500 trims. The ML500 was powered by a 5.0-liter V8 with 302 horsepower. The ML320 CDI and ML63 AMG arrived the next year, with the former offering a diesel engine similar in output to the current Bluetec but without California emissions approval. The ML550 became the standard V8 model for 2008, replacing the ML500. Model year 2009 saw the advent of the ML320 Bluetec and the base rear-wheel-drive ML350, as well as a face-lift front and rear and an available updated COMAND system with Bluetooth phone connectivity. For 2010, the diesel model became the ML350 Bluetec and received a smidge more torque, and the Hybrid model joined the lineup.

The first-generation Mercedes M-Class debuted in 1998 with the ML320, which was motivated by a 3.2-liter V6 with 215 hp. More standard equipment was added in 1999, as well as a more powerful and luxurious V8-equipped ML430 model. Detail improvements in 2000 included an interior freshening and optional third-row seating on all M-Class models, and in 2001 the TeleAid emergency calling system became standard across the lineup. These early ML models suffered from extensive quality-control issues that often resulted in expensive repair bills, so we wouldn't recommend them as used-car purchases.

The Mercedes-Benz M-Class was reworked and improved in 2002 with the modification of more than 1,100 parts and the substitution of the ML500 for the previous ML430, now featuring a 5.0-liter V8 packing 288 hp. Telltale signs included new bumpers, clear-lens headlights and restyled mirrors. In late 2003, the ML350 slotted in above the ML320, featuring a larger 3.7-liter 232-hp V6.

Mercedes was also first to market with a high-performance luxury SUV, offering the ML55 AMG from 2000-'03. Sold in limited numbers, this pricey ML had a 5.4-liter V8 good for 342 hp and 376 lb-ft of torque, along with a sport-tuned suspension.
