Body and Safety: Mature Concept for Reliable Protection.

• All-round occupant protection further enhanced by specific hybrid features.
• Safety concept developed by BMW for the hybrid setting new standards.
• Generous feeling of space in a luxurious ambience.
“The strong and stable body structure of the BMW ActiveHybrid X6 offers ideal conditions for a particularly dynamic and safe vehicle. All hybrid components are fully integrated into the comprehensive occupant safety and protection concept.” Klaus Kompass, Head of Vehicle Safety BMW Group

The superior, dynamic potential of the BMW ActiveHybrid X6 interacts with an exemplary high standard of comfort and safety. At the same time the world’s first Sports Activity Coupé with hybrid drive stands out not only through its unmistakable look, but also through its very generous interior dimensions. The construction of the body and the electronic safety features, in turn, ensure maximum occupant safety together with supreme driving dynamics. And when it comes to space and roominess at the rear and in the luggage compartment, this unique four-seater significantly outperforms all other, conventional coupés.
Proceeding from the high safety standard already offered by the BMW X6, the level of occupant safety has been further enhanced by specific hybrid model features. Hence, the BMW ActiveHybrid X6 offers the integral safety concept for hybrid vehicles developed by BMW in every respect, with central control functions integrated both in the power electronics and the energy storage system.
This strategy sets the foundation for fulfilling various international crash test standards as well as the high internal safety standards of the BMW Group, guaranteeing maximum operating safety of all components within the high-voltage on-board network.

Stable body structure and intelligent lightweight technology for enhanced occupant safety and agility.
The BMW ActiveHybrid X6, like the other models in the BMW X range, comes with a particularly strong and stable bodyshell. To optimise the vehicle’s passive safety, BMW’s engineers and safety specialists focused from the start in developing the body-in-white on making the passenger cell as stable as possible. Forces acting on the vehicle in an accident are therefore spread out on various load paths, for example through the engine supports and the drivetrain, to avoid extreme loads acting on individual structures.
To achieve an extremely high level of stability on minimum weight, the engineers responsible for developing the BMW ActiveHybrid X6 also concentrated consistently on intelligent lightweight technology in the process of development. Both the choice of materials as well as the arrangement and geometry of the support bars, load-bearing elements and trusses are based on an all-round concept ensuring both maximum crash safety as well as superior agility. The extra weight over the BMW X6 xDrive50i resulting from the integration of the wide range of hybrid components is approximately 260 kg or 573 lb.

Hybrid technology protected by an integral safety concept.
The objective in developing the BMW ActiveHybrid X6 was to match the safety concept already proven on the BMW X6 to the particular requirements of the innovative drive system, optimising safety in the process to an even higher standard. The result is the integral safety concept for hybrid vehicles developed specifically for this purpose by BMW.
Some of the features of this safety concept are clearly colour-marked cables, the clear presentation of safety instructions, as well as extra-large insulation covers and newly developed connectors protecting the surface of the entire system. The high-performance battery is fitted in a high load-resistant steel housing and installed firmly within the vehicle. In its position above the rear axle, the battery is very well protected in the event of a collision.
The status of the storage modules is consistently monitored by integral safety electronics, the driver being immediately informed of any malfunction and the modules being automatically discharged and deactivated if necessary.
In the event of a collision the system may be switched off automatically within fractions of a second, the vehicle’s central safety electronics assessing the severity of an accident and ensuring safe operation of the system under all conditions. In less severe accidents the system remains fully functional and is switched off only in a really severe collision.
The safety concept of the BMW ActiveHybrid X6 also ensures full functionality of the electromechanical brake system in the event of the electrical brake-by-wire connections failing to operate. In such a case the pedal force simulator opens up a fallback function within fractions of a second, providing a conventional mechanical connection between the brake pedal and the hydraulic circuit for full brake power and lasting safety even without electrical support.

Six airbags, crash-activated headrests, rollover sensors.
Side curtain/head airbags on the front and rear seats come as standard in the new BMW ActiveHybrid X6 over and above the usual frontal and hip thorax airbags. Inflating out of the covers on the A-pillars and the roof lining, the curtain airbags protect the occupants both front and rear from injury in a collision.
It almost goes without saying that the BMW ActiveHybrid X6 comes on all seats with three-point inertia-reel seat belts. The restraint systems feature belt force limiters and pyrotechnical belt latch tensioners on the front seats.
Further standard features in the BMW ActiveHybrid X6 are ISOFIX child seat fastenings at the rear as well as crash-activated headrests on the front seats significantly reducing the risk of cervical spine injury in the event of an impact from behind.
All restraint systems are masterminded by central safety electronics taking the type and severity of a collision into account and activating the most effective safety components in response. The frontal airbags come with a two-stage gas generator, with the two stages being ignited a few milliseconds after each other, depending on the severity of an accident, to always maintain the right level of intensity.
Rollover sensors masterminding the airbags detect critical driving conditions which might possibly lead to a rollover without a side impact in advance. Networked to DSC Dynamic Stability Control, these sensors ensure a quick and early response of the curtain airbags and belt latch tensioners.

Tyre Pressure Control and runflat tyres to keep the driver going at all times.
Featured as standard in the BMW ActiveHybrid X6, Tyre Pressure Control monitors tyre pressure in each wheel .Whenever tyre pressure drops more than 25 per cent below the required level, a display in the instrument cluster warns the driver and helps to prevent damage to the tyres. In an emergency the special rim contour prevents the tyre from jumping off the rim after a sudden loss of pressure, even at high speeds and in bends.
Reinforced side walls on the tyres, additional reinforcement strips and heat-resistant rubber compounds allow the driver, with the runflat tyres used on the BMW ActiveHybrid X6, to continue on to a workshop even on a completely flat tyre, travelling at a speed of up to 80 km/h or 50 mph and covering a distance of up to 250 kilometres or 155 miles, depending on the load the vehicle is carrying.

Bi-xenon headlights featured as standard, Adaptive Headlights as an option.
Bi-xenon dual headlights featured as standard on the BMW ActiveHybrid X6 ensure optimum illumination of the road ahead almost in the same light as regular daylight not only in the dark, but also as daytime driving illumination provided by the very attractive and practical light rings. This makes the vehicle clearly recognisable also from a distance, the typical daytime driving lights clearly identifying the ActiveHybrid X6 from the start as a BMW.
The BMW ActiveHybrid X6 comes as standard with a light sensor automatically switching on the low-beam headlights as a function of ambient brightness.
The optional High-Beam Assistant ensures additional comfort at night, the system masterminded by a camera at the bottom of the interior mirror automatically switching back to low beam as soon as traffic is approaching the vehicle in the opposite direction or the distance to a vehicle ahead drop below a certain point.
The BMW ActiveHybrid X6 may also be fitted as an option with Adaptive Headlights illuminating the road ahead, following bends and winding contours.
In the process the headlights swivel from side to side in accordance with the position of the steering wheel, the yaw rate, and the speed of the car.
A further function integrated within the system, finally, is the Bending Light function provided by the foglamps.
Variable light distribution also optimises visibility on a straight stretch of road, innovative control of the lights as a function of road speed automatically enlarging the area of vision by broadening the light beam.
To prevent bumper-to-bumper collisions, the BMW ActiveHybrid X6 comes with a warning system for motorists following from behind: Whenever the driver applies the brakes all-out, with ABS cutting in, drivers following from behind are prompted, by the brake lights on the BMW flashing on and off, to also apply their brakes all-out. And after the driver has applied the brakes very hard, bringing the car to a standstill, the hazard warning flashers are automatically activated.

Generous space at the rear, variable luggage compartment.
The BMW ActiveHybrid X6 offers generous space as well as a modern and luxurious ambience for up to four occupants. The comfort seats featured a standard for the driver and front passenger offer a wide range of electrically operated adjustment options, together with a memory function. The rear doors opening up wide, in turn, facilitate access to the two rear seats.
Headroom at the rear is particularly generous for a coupé, 944 millimetres or 37.2” of headroom guaranteeing maximum comfort even for tall passengers.
Seen from the rear, the window graphics in the BMW ActiveHybrid X6 provide the feeling or forward-urging openness and, as a result, a truly generous feeling of space.
The passenger and luggage compartments in the BMW ActiveHybrid X6 are clearly separated from one another in the style typical of a coupé. Luggage capacity available directly behind the rear seats is 470 litres or 16.5 cu ft.
To increase luggage capacity, the driver and passengers may turn down the rear seat backrest in an asymmetric split, enlarging the capacity available to a maximum of 1,350 litres or 47.3 cu ft.
The BMW ActiveHybrid X6 comes with an automatic opening and closing function on the tailgate, the iDrive control system enabling the user to individually set the top position of the tailgate when open. This helps to avoid the risk of damage, for example when parking in a garage or underground car park with a low ceiling.
