2004 BMW 645Ci Coupe

A New Sports Car With Exciting Proportions

The 6 Series Coupe excels in its classic proportions – the car is long, low and wide. It projects an aura of strength and self-confidence. The passenger cabin has a very low roofline and is set back on the chassis.

The modern design language of the exterior continues smoothly and consistently throughout the interior. Similar to the new 5 Series, all the driving controls are located directly on or around the steering wheel. All comfort functions, in turn, are within easy reach from both front seats for convenience. The new 6 Series, again like the original, will not only be admired for its style but will also be recognized as a driver’s car of the first order.

BMW’s Heralded 4.4-liter V8 Offers Performance That Matches Its Style

The 4.4-liter V8 engine already well known from the BMW 745i ensures optimal power and torque over the entire engine speed range. Featuring fully variable VALVETRONIC valve control, the engine develops 325-horsepower and 330 lb-ft of powerful torque at 3,600 rpm. This enables the new 6 Series Coupe to effortlessly reach its top speed of 149 mph (electronically limited). Acceleration is equally good, with the BMW 645Ci covering the sprint from 0-60 mph in well under six seconds.

To convey this refined power to the rear wheels, BMW offers the driving enthusiast the widest range of possibilities—three different six-speed transmissions:

  • Six-speed manual
  • Six-speed STEPTRONIC automatic
  • Six-speed Sequential Manual Gearbox (SMG) featuring both a gearshift lever and shift paddles on the steering wheel, like in Formula One race cars

    The new 6 Series Coupe comes standard with BMW Driving Dynamic Control (DDC). First seen on the Z4 roadster, this feature gives the engine an even more spontaneous reaction to the gas pedal, influences steering in relation to road speed, allows the automatic or SMG transmission to hold gears longer, and provides faster SMG shifts - all at the touch of a button.

    Remarkable Agility Ensured By Intelligent Lightweight Engineering

    Consistent use of intelligent lightweight technologies makes a significant contribution to the outstanding driving comfort and high level of agility for which the new 6 Series Coupe will become well known. This class-leading agility is the result of the innovative combination of aluminum, steel and synthet¬ic materials throughout the body. The front section of the car is significantly lighter than steel thanks to lightweight construction. The targeted weight reduction continues throughout - the trunk lid is composite, the hood and doors are aluminum and the front fenders are thermoplastic. All this contributes to a base weight in European trim of 3528 lb with, of course, weight distribution close to the perfect ratio of 50:50. This consistent reduction of weight ensures not only performance befitting a sports car and exceptional agility, but it also contributes to an outstanding level of fuel economy.

    Handling and Responsiveness:
    The Synergy of Aluminum Suspension and Cutting Edge Technology

    The lightweight all-aluminum suspension of the new 6 Series Coupe keeps unsprung weight to a minimum. Also working to the driver’s advantage are myriad control systems such as Dynamic Stability Control (DSC) including Dynamic Traction Control (DTC). All 6 Series Coupes feature BMW's Active Roll Stabilization, which almost completely eliminates body roll. Part of the Sport Package in the U.S. will be BMW's unique Active Steering, which electronically varies the degree to which the front wheels turn in relation to steering input from the driver. Under normal driving conditions at low and medium speeds, the steering ratio becomes more direct, which causes the front wheels to turn more in relation to the steer wheel. This enhances the car’s performance in city traffic, when parking or in curves. At higher speeds, the steering ratio becomes more indirect, which causes the front wheels to turn relatively less in relation to the steering wheel, offering greater directional stability. Active Steering works hand-in hand with Dynamic Stability Control (DSC) by monitoring the yaw rate and changing the steering angle accordingly. This reduces the number of DSC interventions and thus offers optimum control comfort for the driver and passengers.

    In addition to all the safety features characteristic of a BMW, the new 6 Series Coupe utilizes run-flat tires, allowing the driver to continue for a certain distance even when a tire is completely flat. Adaptive Headlights, which enhance visibility, illumination, and improve the driver’s field of nighttime vision, are also available as an option.

    Other Features Include Head-Up Display and Glass Panorama Roof.
