Body and Safety: Strong Character

  • Mean body stiffness up by 30 percent.
  • Targeted use of high-strength and ultra-high-strength steel; doors, engine lid and spring supports made of aluminium.
  • Active engine lid for optimum pedestrian safety.

The exterior design of the new BMW 5 Series Touring offers a perfect balance of aesthetic looks and sporting dynamics in a unique interpretation of the touring concept. The body structure sets new standards in terms of solidity and intelligent lightweight construction. The use of the most appropriate materials serves to meet the highest demands on passive safety and at the same time optimise the weight of the car in the interest of enhanced efficiency and driving dynamics. A wide range of safety components interacting precisely with one another in a carefully coordinated overall concept guarantees excellent occupant safety whenever a collision is unavoidable. The safety concept of the new BMW 5 Series Touring also incorporates fundamental structural and innovative technologies for optimising pedestrian safety on the road, thus adding reliable protection in all conceivable crash situations to the sheer driving pleasure so characteristic of a BMW. Hence, the new BMW 5 Series naturally meets all requirements for achieving excellent results in all crash tests the world over.
Like the sedan, the new BMW 5 Series Touring comes with an extremely stiff passenger cell, intelligent use of high-strength multi-phase steel and hot-moulded ultra-high-strength steel, giving the safety passenger cell maximum stiffness on relatively low weight. Compared with the former model, mean stiffness of the body structure is up by approximately 30 percent in the interest of optimum passive safety and as the foundation for excellent driving dynamics. The lightweight quality rating, that is torsional stiffness as a function of the car’s footprint and overall weight, is also absolutely outstanding.

Aluminium doors reducing the weight of the car by 23 kg or 51 lb.
Apart from the engine lid, the front side panels and the front spring supports on the body, the doors of the new BMW 5 Series Touring are also made of aluminium. Indeed, the use of aluminium doors alone instead of conventional steel components serves to reduce the overall weight of the car by approximately 23 kg.
With its particular moulding requirements, aluminium demands a far more sophisticated production process than steel. A new structural concept developed by BMW nevertheless allows the use of aluminium in the proven shell plate structure, maintaining the design features typical of BMW also when using this extra-light material.

Longest wheelbase in the segment for perfect proportions, harmonious axle load distribution, generous interior space and maximum occupant safety.
The wheelbase of the new BMW 5 Series Touring measures 2,968 millimetres or 116.9 inches, thus setting a new record in the upper midrange segment. This sets the starting point for the ideal proportions of the car crucial to both its looks as well as its driving characteristics and the high standard of occupant safety provided by the new BMW 5 Series Touring. Short overhangs and a longer front section than on the former model, with the engine fitted further behind the front axle, provide weight distribution close to the ideal of 50 : 50 on all variants of the new BMW 5 Series Touring. At the same time, the proportions offer optimum conditions for implementing the demanding safety concept with maximum occupant safety as well as innovative features serving to protect pedestrians in the event of a collision.
The seating position has been further optimised over the former model both front and rear, with legroom on the rear seats of the new BMW 5 Series Touring increased by 13 millimetres or 0.5 inches. Luggage compartment capacity is 560 litres, and the folding rear-seat backrest available as an option provides greater flexibility in enlarging the car’s transport capacities. In addition to its 40 : 20 : 40 split, the rear-seat backrest can be either partially or completed folded down, whilst it is also possible to vary the backrest inclination angle. Through adjustment in the upright position, the luggage compartment volume is increased by 30 litres.
Storage capacity is 1,670 litres with the backrest completely folded down.

Panorama sunroof: more light and harmonious design.
The panorama sunroof allows a precise flow of fresh air into the car and bright light within the passenger compartment, emphasising the sheer generosity of the ambience inside the BMW 5 Series Touring. It is electrically driven, features a light-proof inside lining and is significantly superior to the conventional glass sunroof in terms of size and function. The glass panel now measures 116 cm/46” in length and 94.2/37” cm in width, with an opening of 44 cm/17”.The rigid structure of the rear glass panel, which is firmly screwed into the car body, contributes additionally towards the vehicle’s stiffness. A further highlight is the harmonious integration of the glass panel into the outer skin of the car ensured by the contoured sweep at the front end of the glass panel following the front edge of the roof. Precise mechanical alignment ensures a highly accurate connection of the front edge of the glass roof and the seal on the sliding roof, also when the roof is in vent position, preventing any unpleasant noise caused by air swirl.
The control unit for the electric operation of the panorama sunroof is integrated into the roof liner together with the interior light switches. The interior roller blind is also electrically driven, the inside matching the decor of the roof liner, harmoniously blending in with the car’s interior. Moreover, the space-saving integration of the blind into the roof liner provides additional headroom at the rear of the car.

Comprehensive occupant protection on all seats.
Highly load-resistant bearing structures, generous and exactly defined deformation zones as well as highly efficient restraint systems coordinated by the car’s high-performance electronic control units set the foundation for a high standard of passive safety in the new BMW 5 Series Touring.
Forces generated in a head-on collision are diverted by several load paths in the floorpan, on the side frame, in the bulkhead and in the roof, absorbed by the deformation zones and thus kept away from the passenger cell. The load-bearing structures forming the load paths are made largely of multi-phase steel and hot-moulded steel, an additional bumper system around the front axle serving to spread out the forces acting on the front section of the car.
Reinforced side structures in the B-pillars and the side-sills, extra-strong door reinforcements and stable crossbars on the seats limit the depth of deformation as well as the speed of intrusion in the event of a collision from the side. With its reinforced pillars and roof supports, the passenger cell also offers safe survival space for the occupants in the event of a rollover.
Inside the new BMW 5 Series Touring, the frontal and hip thorax airbags are supplemented by curtain head airbags at the side for both rows of seats as a standard feature. Depending on the type and severity of a collision, the integrated safety electronics determine the restraint effect provided and the time of release.
All seats feature three-point inertia-reel seat belts and belt force limiters, with an additional belt latch tightening function on the front seats. To prevent cervical spine injury in the event of a collision from behind, the front seats come as standard with crash-activated headrests. Masterminded by the car’s safety electronics, these headrests move up instantaneously in the event of a collision, closing the gap between the front end of the headrest and the occupant’s head by up to 60 mm or 2.4” front-to-rear and up to 40 mm/1.6” in a vertical direction. The occupant’s head is therefore very close to the headrest even before being moved back by the forces acting on the car. This enhances the stabilising and protective function of the headrests and reduces the risk of injury or hyperextension of the occupant’s cervical spine.
Moreover, both ISOFIX child seat fastenings at the rear and the option to deactivate the front passenger’s airbag naturally come as standard.
The safety steering column on the new BMW 5 Series, in turn, comes with a load-related deformation element as well as an extra-large spacer unit protecting the driver additionally from collision forces coming from the engine compartment.

Active bonnet for optimised pedestrian safety.
To optimise the high standard of passive pedestrian safety, the new BMW 5 Series Touring comes, depending on national specifications, with an active bonnet, which automatically moves up in the event of a collision with a pedestrian. The pyrotechnical release mechanism is activated at speeds of between 25 and 55 km/h (16 - 34 mph) as soon as data acquired by sensors at the front of the car indicate a collision with a pedestrian, raising the bonnet at the front and the rear.
This provides additional deformation space beneath the bonnet, thus absorbing impact energy and serving to lessen the risk of injury, or at least the consequences of an accident.

Optimum visibility: bi-xenon headlights, LED daytime driving lights and Adaptive Headlights with variable light distribution.
The dual round headlights on the new BMW 5 Series Touring so typical of the brand ensure excellent illumination of the road in the dark and in the event of poor visibility due to bad weather. On the standard headlights, LED light rings serve as positioning lights, again in typical BMW style, forming a clear and consistent circle of light. Further standard features are the fog lamps and the light sensor automatically activating the low beam according to ambient brightness. A rain sensor determining the intensity of precipitation and thus allowing automatic adjustment of the windscreen wipers is likewise fitted as standard.
The new BMW 5 Series Touring is available as an option with bi-xenon headlights, in which case the LED units in the characteristic light rings can be operated in two stages. Dimmed to approximately 10 percent of their full power, they serve as positioning lights. Switched to 100 percent, they provide a daytime light function in typical BMW style.
In conjunction with the optional bi-xenon headlights, the new BMW 5 Series Touring can be equipped with the latest generation of Adaptive Headlights with cornering lights, variable light distribution and adaptive headlight range control. Adaptive Headlights ensure that the road is sufficiently illuminated when taking bends. Each turning direction of the headlights is effected in relation to steering angle, yaw rate and vehicle speed. The cornering light function is integrated into each headlight. When cornering, an additional light cone is produced in order to illuminate the road in the direction the vehicle is moving.
The adaptive headlight range control function also takes vertical road contours into account. When driving over hillcrests, through tunnels or on steep ramps the light cone is lowered or raised accordingly in order to ensure optimum illumination of the road without dazzling oncoming traffic. Adaptive Headlights also feature variable light distribution, a function that also guarantees an optimised illumination of the carriageway on straight roads. The innovative control system automatically facilitates according to speed an amplification of the field of vision through adequate widening of the light cone.
The rear lights on the new BMW 5 Series Touring generate their strong effect and clear visibility through three-dimensional, homogeneously glowing light bodies. The taillights, brake lights and direction indicators feature LED technology. To avoid collisions from behind, the new BMW 5 Series Touring is equipped with a special warning system for motorists behind. This is a further development of the Adaptive Brake Lights introduced by BMW as the world’s first manufacturer to offer such a feature. When applying the brakes particularly hard and when ABS is activated, drivers following from behind are immediately alerted by the brake lights conspicuously flashing on and off, prompting drivers behind to brake equally as hard.  After the car has come to a standstill following particularly powerful application of the brakes, the hazard warning flashers are automatically activated.
