Chassis Management and optional Integral Active Steering.
Cutting-edge chassis technology gives the new BMW 650i Coupe the tools to provide both sporty handling and exceptional comfort. The double wishbone front axle and the multi-link rear axle are made predominantly from aluminum. The chassis is geared to the requirements of drivers with sporting intentions, although the dampers also respond sensitively to bumps in the road surface under high lateral acceleration. The optional Active Roll Stabilization combines with the standard Dynamic Damper Control to offer the driver even more precise responses and perfectly flat cornering ability. The electronically controlled shock absorbers adapt to the road surface and the driver’s style to perfectly control the car’s body motions.
The electronically controlled damper system in the new BMW 6 Series Coupe adjusts compression and rebound settings continuously and independently. For example, a stiff chassis setting can be combined with comfortable responses to unevenness in the road surface. The control unit of the damping system processes the data supplied by sensors on the vertical motion of the wheels as well as the ride height of the car. The driving speed and the damper setting chosen by the driver are also taken into account in calculating the damping force required for each individual wheel to even out body movements. This data is fed back to the shock-absorber units at intervals of just 2.5 milliseconds.
The optional Active Roll Stabilization feature reduces body roll in corners and in sudden changes of direction, or transitions. Sensors calculate the amount of body roll based on the driving situation at hand, and this is then counteracted quickly and precisely by hydraulic rotary actuators in the front and rear anti-roll bars. The result is flatter cornering inspiring greater confidence for the driver as well as greater comfort for the passengers during spirited drives. The power steering features standard Servotronic vehicle-speed sensitive assistance, and serves up the familiar BMW recipe of precision, comfort and linear response.
The new BMW 650i Coupe is the first car in its class available with Integral Active Steering. This system combines the Active Steering system for the front axle (available on the previous generation 6 Series Coupe) with a new, steerable rear axle. Precisely harmonized steering angle movements at both axles create a virtual lengthening or shortening of the vehicle’s wheelbase, which fosters greater high-speed stability and enhanced maneuverability for parking and city use.
Brakes, Wheels, and Tires.
The lightweight floating-caliper brakes with vented discs are easy to use with precision, and their effectiveness is reinforced by Dynamic Stability Control. DSC brings together technology such as the Anti-lock Braking System, Dynamic Traction Control, Cornering Brake Control, Dynamic Brake Control, the Start-off Assistant, the automatic Brake Drying function and Brake Fade Compensation. Standard equipment also includes 8.5 x19-inch light-alloy wheels, with all-season runflat tires (size 245/40 R19) and a tire pressure monitoring system.
Driving Dynamics Control.
With standard Driving Dynamics Control, the dominant virtues of athletic driving sportiness and ride comfort can be chosen by the driver as situations demand. The driver can choose settings of COMFORT, NORMAL, SPORT and SPORT+ modes using the large rocker switch on the center console. Affected parameters include the tuning of the throttle response, power steering boost assistance, shock absorbers, automatic transmission shift characteristics and – if equipped - roll stabilization and Integral Active Steering. In SPORT+ mode, the Dynamic Traction Control mode of the standard Dynamic Stability Control system is activated, raising the thresholds for stability intervention in the most sport-oriented driving circumstances.
Unmatched chassis technology works with the cutting-edge engine to provide the driver with greater dynamic capability and improved ride comfort compared to the previous-generation 6 Series Coupe.
Design: Athletic elegance, natural sportiness.
The new BMW 6 Series Coupe again heralds the arrival of an exceptionally sporty and exclusive 2+2-seater in the premium Coupe segment. The new model’s extra length and width over its predecessor model combine with its 0.2 inch (5 mm) lower height to produce a strikingly low-set and powerful design. The new interpretation of the traditional BMW Coupe proportions is embellished by lines and surfaces inspired by the movement of waves. Flowing lines and harmonious curves create a feeling of athletic grace, complemented by extremely classic and eye-catching design features which underline the opulent character and elegant appearance of the two-door BMW.
The expressive front end is dominated by the large and slightly forward-slanting BMW kidney grille. The grille emphasizes the car’s sporting pedigree with a broad, flat design, and creates a visual connection with the engine nestling behind. The kidney grille slats, angled slightly towards the top, lend additional emphasis to the front end’s “shark nose” character. The contour lines of the hood converge towards the kidney grille, forming a V-shape which is continued by the contours of the headlights, kidney and wide air intake to give a road-focused look. High-quality chrome elements and the LED units of the foglamps positioned in front of them guide the eye to the muscular wheel arches.
