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”.
