What's New

The 6 Series debuts for the 2005 model year. The sporty coupe or convertible offers a fresh design and plenty of features and extras to please BMW fans.


BMW has long been known for creating good looking vehicles with plenty of style and class. The 2005 6 Series makes no exception. The front end and grille look impressive, especially with the hooded headlights the German carmaker earns attention for. On the other end, the 6 Series features a tall, somewhat angular tail. In some circles it has been dubbed the ?Bangle butt,? named for the BMW chief of design, Chris Bangle. Between the front and back ends, the 645Ci is all elegance and style. Slightly scooped sides and modern lines give the coupe a refined appearance sure to make an impression wherever it goes.


The inside of the BMW 6 Series has a lot character and style to match the exciting exterior. The main question on everyone’s mind concerns the iDrive feature BMW designed to meet criticisms of its earlier designs in terms of a cluttered dash and control panels. The iDrive system does away with most of the buttons and knobs in the cabin and replaces them with a computer controller. Test drivers find the system difficult to work with, though the idea seems good in theory.

The rest of the cabin remains typical for BMW. It feels comfortable with supportive seats and available aluminum or wood accents. It has to be noted that the back seat seems relatively small and adult passengers need to appreciate a tight fit or wait until they can ride in the front.

Performance & Handling

The 6 Series from BMW uses an impressive V-8 engine, that when paired with any of the three available transmission options does a good job on road or highway driving. Part of what makes this car so impressive stems from how adeptly the V-8 and coupled transmission handle the heavy weight of the 6 Series. Even with a composite plastic truck and aluminum doors and hood, the 645Ci weighs well over 3000 pounds. If you opt for the convertible, add another 400 pounds. You wouldn’t know it to drive it though. It feels as light as air around twists and turns, as well as on the highway. No one can deny the intoxicating sounds from the V-8 engine. When cruising along, it sounds low and easy. During acceleration, the engine sounds like a beast, impressing and intimidating every car in its path.


The 2005 BMW 6 Series or 645Ci comes fully loaded with all kinds of safety features. While this car focuses on its looks and performance, BMW still takes safety seriously. Each one of these cars comes equipped with four-wheel anti-lock brakes, traction control, and a tire pressure monitor. The 645Ci also features stability control, side front airbags, and daytime running lights, among others.
