BMW 645Ci (2004)

BMW 645Ci

Although the BMW 6-Series designation had been last applied to a BMW in 1989, BMW has a long tradition of sport coupes and convertibles of the highest caliber. In the spirit of this tradition, BMW introduced a new 6-Series in 2004, consisting of two models of surpassing design, technology and excitement.

The 6-Series models are the BMW 645Ci Coupe, at $70,595 including destination charge, and the BMW 645Ci Convertible at $77,595. Each is powered by the brilliant 4.4-liter, 325-hp Valvetronic V8 that had already been winning hearts and minds in the 745i/Li and 545i models.

And since "6" falls between "5" and "7," it will not surprise that this new sport Series is related to the 5 and 7-Series. Yet the 6-Series is anything but a mere re-bodying of either of these sedans. For a perspective on how the new models fit into the upper end of the BMW line, consider the following:

• Compared to the 5-Series, the 6 rides on a wheelbase 4.3 in. shorter, yet is almost as long thanks to the 6's long-hood, cabin-back proportions. Compared to the 745i, the 6-Series wheelbase is 8.3 in. shorter, reflecting the contrast between the 7's large, commodious sedan format and the 6's more intimate, sporting coupe/convertible character.
• A notably wide rear track and low height visually express the 6-Series' sporty handling attributes.
• No sheet metal is shared with either the 5 or 7-Series.
• BMW's most extensive use of weight-saving body materials in regular-production models results in impressive weight efficiency.
• Though all three Series use the Valvetronic V8 engine, the BMW 645Ci Coupe achieves the best acceleration
• Like the 545i but not the 7-Series, both 645Ci models are available with all three BMW transmission types: manual, STEPTRONIC automatic and Sequential Manual Gearbox (SMG). All are 6-speeds.
• Whereas the 5 and 7-Series Sedans are full 5-seaters, the BMW 645Ci models are 2+2s, with generous front seating space and intimate, yet inviting "occasional" rear seating.
• Thanks in part to standard run-flat tires, the BMW 645Ci Coupe provides almost as much trunk space as the 545i; the Convertible trunk, with its variable softtop storage compartment, is also relatively spacious for a car with a folding top.
