2008 BMW 550

The BMW 550 received a few minor styling updates for 2008, including a slightly revised front grille and new LED headlights and taillights. But the 550 essentially retains its sleek, glass-like exterior, a design introduced in 2004 and one that remains controversial with some die-hard BMW fans.

The 550's status as the top-of-the-line model in the automaker's 5 Series, however, is undisputed, thanks to its 360-horsepower, 4.8-liter V8 engine, which is not only powerful but fuel-efficient as well, thanks to such technologies as Valvetronic, which varies valve lift at moderate speeds to conserve fuel.

The 550 is available with either a six-speed manual transmission, which is standard, or a six-speed automatic, which is available at no extra cost.

The 2008 BMW 550 is equipped with a number of cutting-edge features, including an optional head-up display that projects critical information into the driver's line of vision, an Active Cruise Control system that maintains a pre-set distance from the car ahead, Adaptive Brake lights that shine larger and brighter in an emergency situation, and a Park Distance Control system, which provides an audible alert to help drivers park.

Inside are such features as a three-spoke, leather-wrapped multifunction steering wheel, Dakota leather upholstery and interior trim, 10-way powered front seats, a two-way power glass moonroof, power windows, power door locks with a keyless remote entry system, and a full range of airbags.
