2007 brings two new models that expand the Mercedes M-Class line to four. Each is equipped with a seven-speed automatic transmission and electronically managed 4ETS fulltime all-wheel drive. The primary distinguishing feature is each model's engine.
The ML350 ($42,680) is powered by Mercedes' latest-generation 3.5-liter gasoline V6, generating 268 horsepower. It comes with vinyl upholstery, automatic headlights, power seats, and an eight-speaker stereo with CD.
The ML320CDI ($43,680) is equipped similarly but with the 215-hp 3.2-liter diesel V6 rated at 398 pound-feet of torque.
The ML500 ($49,200) gets a three-valve, twin-spark 302-hp V8 and more standard features. These include heated, leather covered front seats, rain-sensing wipers and Tele-Aid emergency communication. The ML500 also includes more potent brakes and an upgrade from 17-inch to 18-inch alloy wheels.
The ML63 AMG ($85,500) features a 6.2-liter V8 that generates 503 hp along with an AMG transmission, AMG shocks and suspension tuning, high-performance P295/40ZR20 tires on 20-inch wheels, AMG brakes, an air dam and other aerodynamic aids, AMG instruments, harman/kardon Logic7 CD6 audio with 12 speakers, and leather upholstery.
Options include Distronic radar-managed cruise control ($3,150), Parktronic obstacle warning ($760), the DVD-based navigation system ($1,650), dual-screen rear-seat DVD entertainment system ($2,800), Keyless Go starting ($1,100), iPod integration kit ($365), CD6 changer ($440). Three packages are available, designated Premium I ($2,800), PII ($5,800), and PIII ($8,600), with exact content tied to the model. Drivers who want the racy look and sportier handling of the ML63 AMG, but not the high-power engine, can order the AMG Sport Package ($4,550) on any M-Class model.
Safety features on all models includes two-stage front airbags for the driver and front passenger, side-impact airbags front and rear (torso protection) and curtain-style head protection airbags. A rollover sensor can activate both the seat-belt tensioners and curtain airbags if the vehicle senses an imminent rollover. An Electronic Stability Program comes standard along with advanced anti-lock brakes with electronic brake-force distribution. A tire pressure warning system is also standard.
