The V8 has grown from 4.4 to 4.8 liters, with an increase of 35 horsepower and 30 pound-feet of torque, peaking at 360 in both cases. This engine is packed with the latest in materials and control technology. A six-speed manual transmission is standard, but either a six-speed automatic with the Steptronic manual shift feature or a six-speed sequential manual gearbox (no clutch pedal) is available as a no-cost option.

Both the coupe and convertible come standard with a long list of luxury features, including leather upholstery, a choice of interior trim, dual-zone automatic climate control with air cleaner, a high-power, eight-speaker stereo, xenon adaptive headlamps, moonroof, and BMW's Park Distance Control front and rear park-assist system.

There are three major option groups. The Premium Sound Package ($1,800) includes Logic7 audio with 13 speakers and a six-disc CD changer. The Cold Weather Package ($750) includes heated front seats, a heated steering wheel and a ski bag pass-through from the trunk. The Sport Package ($1,800) adds sport seats and 19-inch wheels with high performance run-flat tires, but no longer includes BMW's Active Steering system.

Standalone options include the Active Steering ($1,250), radar-managed Active Cruise Control ($2,200), satellite radio hardware, ($595) and heated front seats ($500).

The 6 Series comes with the full range of active and passive safety equipment, starting with front and side-impact airbags. The 650i Coupe is also equipped with curtain-style head protection airbags, while the 650i Convertible has automatic rollover protection that deploys high strength roll hoops behind the seats. Accident avoidance features include electronic stability control, ABS with brake assist and electronic brake-force distribution. BMW Assist telematics, with automatic collision notification, an SOS button and roadside assistance, are standard, including a one-year subscription. There's also a really cool first-aid kit in every 6 Series.
