2013 BMW 640 Overview
Redesigned last year, the BMW 640i comes with a turbocharged inline-six and is offered in coupe and soft-top convertible variants, both of which seat four. The Jaguar XK is the 6 Series' most direct competitor, but you might cross-shop the car against a Mercedes-Benz E-Class coupe or cabriolet, too.
The 6 Series maintains a short front overhang and low-slung appearance. BMW says the design was inspired by the natural motion of waves.
The convertible's fully automatic soft-top has what BMW describes as a flying-buttress design in which the top trails behind a vertical rear window, maintaining a coupe-like roofline. The top, which can be operated at the touch of a button at speeds up to 25 mph, comes in black or beige. Exterior features include standard 18-inch wheels (19- or 20-inch wheels available), adaptive xenon headlamps, and a glass sunroof with power-sliding sunshade. Adaptive LED headlights are optional.
The interior has a 2+2 seating configuration with small rear seats. Trunk volume in the coupe is about 30 percent more than the convertible with its top up; with the top down, the convertible loses another 14 percent. Standard interior features include power-adjustable seats and iDrive with a 10.2-inch high-resolution screen and navigation. Ventilated and massaging front seats, a heated steering wheel, and a Bang & Olufsen premium stereo are optional.
Under the Hood
The 640i is powered by a 315-horsepower, turbocharged 3.0-liter six-cylinder engine. An eight-speed automatic transmission with steering-wheel-mounted shift paddles is standard and the 640i employs rear-wheel drive.
Both the coupe and convertible have front airbags plus side-impact airbags built into the front seats. Safety features include antilock brakes, electronic stability system, pop-up roll bars in convertible, backup camera, and front and rear parking sensors. There is also plenty of optional safety technology, including parallel-parking assist, surround-view system, blind spot warning system, lane departure warning system with frontal collision warning, and night vision with pedestrian detection.
