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, say, 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.
Wheelbase of the new BMW 5 Series Sedan measures 2,968 millimetres
or 116.9”, 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 Sedan. 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 Sedan. 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 kneeroom on the rear seats of the new BMW 5 Series
Sedan up by 13 millimetres or 0.5”. Luggage compartment capacity is
520 litres or 18.2 cubic feet, and the folding rear-seat backrest available as
an option provides greater flexibility in enlarging the car’s transport capacities.
In addition to its 40:60 split, the rear-seat backrest also comes with through-
loading and, as yet a further option, a ski-bag for additional convenience.
Contoured sliding roof: more light and harmonious design.
The contoured sliding roof 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 car. The contoured sliding roof has
been further optimised on the new 5 Series Sedan in terms of both size
and function compared with a conventional glass roof, the glass panel now
measuring 60 cm/23.6” in length and 92 cm/36.2” in width, with an opening
of 39 cm/15.4”.
