Chassis and Suspension, Driver Assistance Systems, Safety: Innovations to Make Motoring a Genuine Experience.
• All-aluminium chassis, Active Steering, Dynamic Drive.
• Greater safety and comfort ensured by Lane Departure Warning and Active Cruise Control with Stop & Go.
• Optimised occupant safety with active headrests.

Both the new Coupé and the new Convertible in the BMW 6 Series combine fascinating sportiness and superior driving behaviour at all times. High-performance power units, the transmission of power to the rear wheels, well-balanced axle load distribution and a modern all-aluminium chassis ensure superior agility, safety, and comfort under all conditions. The principle of intelligent lightweight technology, in turn, gives the chassis and suspension supreme stability combined with even lighter weight and unsprung masses reduced to a minimum.
The spring-strut tiebar front axle, as one example, is made completely of aluminium, with the exception of just a small number of components subject to particularly great loads such as the track rods, wheel bearings or pivot arms.
The integral-IV rear axle is also made almost completely of aluminium, with the four control arms guiding the rear axle being fastened not directly to the body of the car, but rather elastically on an axle subframe in order to optimise the car’s tracking stability and motoring comfort.


Built-in safety: runflat tyres and tyre defect indicator.
Both the BMW 630i and the BMW 635d come as standard with 17-inch light-alloy wheels. The BMW 650i, in turn, boasts 18-inch light-alloy wheels as a standard feature.
All tyres on all models are runflat tyres enabling the driver to continue to the nearest workshop even under a complete loss of air pressure. And last but certainly not least in this context, the tyre pressure indicator permanently monitors air pressure and warns the driver once tyre pressure drops more than 30 per cent below the ideal level by way of an optical signal in the instrument cluster.

Shorter stopping distances, even faster brake response.
The high-performance swing-calliper brakes with inner-vented brake discs are controlled hydraulically on all models in the new BMW 6 Series.
As a result, these highly effective brakes now come in even faster and more precisely, ensuring maximum stability and full brake power at all times.
Another forte of the premium brake system on the new BMW 6 Series is its low weight.
The brake system on the BMW 650i offers a particular high standard of all-round performance reflecting the supreme power of the engine. And again last but not least, the BMW 6 Series comes as standard with a continuous wear indicator informing the driver at all times on the condition of the brake pads.

DSC Dynamic Stability Control with optimised control functions.
Offering a wide range of different functions, DSC Dynamic Stability Control supports the driver in handling his BMW with maximum safety and supremacy. The first and foremost function of DSC is to apply the brakes as required on individual wheels or intervene in engine management in order to avoid under- or oversteer in bends.
The system also comprises ABS brake control as well as ASC Automatic Stability Control preventing the drive wheels from spinning on slippery or loose surfaces, a Brake Assistant and CBC Cornering Brake Control. Further functions are Fading Compensation whenever the brakes become particularly hot, regular Dry Braking serving to optimise brake power in the wet, and a Start-Off Assistant for leaving a parking position on an uphill gradient smoothly and without rolling back, without being required to use the handbrake in the process.
The Brake Assistant featured as part of the DSC system in the new BMW 6 Series is networked with other driver assistance systems, the combination with Active Cruise Control complete with Stop & Go available as an option using radar sensors to determine the need for extra stopping power at an even earlier point. In this case the brake system is pre-loaded by reducing the release thresholds of the hydraulic Brake Assistant and brake pressure is built up immediately in the brake system to move the brake pads closer to the discs without causing any noticeable deceleration of the car.
In the event of an emergency braking manoeuvre, these safety measures serve to build up maximum stopping power much more quickly, making the car’s stopping distance a lot shorter and providing valuable safety reserves.
Optimised control by the DSC system ensures very sensitive intervention whenever required under extreme conditions. Enhanced DTC Dynamic Traction Control activated at the touch of a button without in any way impairing the car’s power and performance, in turn, is a particularly good match for the sporting character of the BMW 6 Series.
The DTC mode moves the response thresholds of DSC Dynamic Stability Control to a higher level, enabling the driver, for example, to set off smoothly in deep snow, deliberately allowing the wheels to spin slightly.
A further advantage of DTC Dynamic Traction Control optimised on the new BMW 6 Series is the increase in lateral acceleration up to a controlled power slide in bends. And if he wishes, the driver is naturally able to completely deactivate DSC in order to meet his personal demands.
