2008 Mercedes-Benz M-Class Review

The family of Mercedes ML models, together referred to as the M Class, cover a range of duties from family-hauling and cargo-hauling errands to moderate off-roading-all in comfort and luxury.

The base ML350 has a 268-horsepower, 3.5L V6 engine, while the mid-range ML320 CDI has a 3.0L turbo diesel V6 that offers the power of a V8 with the fuel economy of a four-cylinder, according to Mercedes. At the top of the line is the ML63 AMG, with a powerful 503-horsepower, 6.3L AMG-built V8. Each model comes with a seven-speed automatic transmission.

For 2008, the ML550 makes its debut, replacing the ML500. It comes with a 382-horsepower, 5.5L aluminum-block V8, plus a standard sunroof, exclusive AMG styling and 19-inch AMG wheels, and running boards.

Both the V6 and V8 have variable valve timing, a tumble flap, and a two-stage intake manifold for good throttle response whether in stop-and-go traffic or passing at high speed. The ML550 can accelerate to 60 mph in 5.6 seconds, according to the manufacturer.

All ML models include the 4Matic full-time four-wheel-drive system, which has a low range for off-roading. A sophisticated traction control system assists the drive system and incorporates a downhill speed regulator and hill-holder for stability on steep slopes with limited traction.

The ML is built on a unibody platform and has an independent suspension-double-wishbone front suspension and four-link rear setup-for good, carlike handling and a smooth ride.

Standard safety features on the ML include front side air bags, side curtain air bags that span all outboard occupants, active headrests to help prevent whiplash, and the Pre-Safe system, which prepares safety systems for an anticipated crash.

The M Class has spacious seating for five adults, and the 60/40-split second row folds forward to expand the cargo area when needed. The stylish interior especially stands out for its available burl walnut or aluminum trim.

Standard equipment includes dual-zone climate control, power front seats, cruise control, a power sunroof, a multi-function steering wheel, dual heated side mirrors, and a retractable cargo cover. The ML320 CDI has similar equipment to the ML350, but the ML550 adds heated front seats, larger front brake discs, burl walnut trim, running boards and a rain sensor. At the top of the line, the ML63 brings Airmatic suspension, huge 20-inch alloy wheels, an AMG Nappa leather interior with sport seats, burl walnut trim, and a CD changer.

Major options through the line include the COMAND in-dash multi-media interface and navigation system, the height-adjustable Airmatic air suspension with active damping, a harmon/kardon Logic 7 sound system with auxiliary input, a rear-seat entertainment system, heated rear seats, an ambient lighting package, and bi-xenon headlamps that swivel to help illuminate into corners.
For 2008 there are a number of equipment changes to Mercedes-Benz's V6 ML350 and diesel ML320 CDI, including larger, 19-inch wheels, a new grille and trim, and a standard power sunroof. A new ML550 model replaces the ML500, and it includes the new-generation, 382-horsepower, 5.5L V8, as well as additional equipment from in-house tuner AMG. The high-performance ML63 AMG carries over with no significant changes.

Also, a limited-edition, "Edition 10" V6 model for 2008 comes loaded with features and celebrates the tenth anniversary of the M Class. It has a unique interior scheme with Birch and Macadamia woods and black leather, special Obsidian Black or Arctic White paint, and a chrome shadow finish for the grille and skid plates. see less
