BMW 6 Series Specs, Engines & Dimensions (2007–2010) — Second Generation Restyling
The restyled BMW 6 Series pairs grand-touring appeal with a choice of Coupe and Cabrio bodies. Your decision comes down to roof preference, powertrain character and the equipment fitted to each car.
Among the Cabrio examples, the 635Cd 3.0 AT combines diesel pulling power with automatic convenience, while the gasoline 630Ci 3.0 MT gives you direct control over gear changes. The 645Ci 4.4 DSG pairs gasoline power with a robotic transmission. These rear-wheel-drive versions show why your BMW 6 Series engine choice should account for transmission feel, too.
For the 630Ci 3.0 AT, the 630Ci Cabrio designation alone does not tell you every fitted feature. When comparing BMW 6 Series trim levels, check the individual car’s upholstery, seat adjustments and audio system, since a shared powertrain does not guarantee identical equipment.
