The GL-Class launches with a single model. The 2007 Mercedes-Benz GL 450 comes with a 335-hp V8 engine similar to the one in the new S-Class sedan. Additional models will be coming, starting early in calendar year 2007 with the GL 320 CDI, which comes with a diesel engine. Later, the GL will be available with Mercedes' breakthrough BlueTec diesel powertrain.

The Mercedes-Benz GL 450 ($54,900) comes with a 4.6-liter V8 engine, seven-speed automatic transmission, the 4MATIC four-wheel drive system, and the Airmatic air suspension system. It comes with seating for seven and with a third row that powers up or down at the touch of a button.

Options include Distronic radar-controlled cruise control; a rear-seat entertainment system with two screens; Keyless Go, which allows the car to be started as long as the key is inside the vehicle; Parktronic, which uses sonar to detect obstacles near the vehicle; a power rear tailgate; Harman/Kardon Logic 7 surround sound system; and DVD navigation.

Safety features that come standard include eight airbags, including side airbags for all four outboard first and second-row seating positions as well as side curtain airbags that protect occupants in all three rows. It comes with active front head restraints, LATCH tethers for child safety seats, and three-point safety belts for all seating positions; make sure everyone in the vehicle always wears those seat belts because they're your first line of defense in a crash. Active safety features (to help you avoid a crash) include an Electronic Stability Program, anti-lock brakes with Brake Assist Plus, and four-wheel electronic traction control. Optional safety features include Parktronic and a rear-view camera, each of which can help alert the driver obstacles or people, including children, behind the vehicle.
