Citing unnamed sources, Autocar reports that the next generation 2015 BMW 7 Series will shed some weight when compared to the current F01/F02 models. The UK magazine also quotes development boss Herbert Diess who calls the new 7 Series the most technically advanced car in BMW’s history.
In the past we reported that G11 7 Series’ structure would probably feature a mix of materials, with the carbon fiber parts being added to the aluminum and steel used in today’s car. The roof, bonnet and bootlid are most likely to be made from CFRP. The magazine comes to confirm our own findings as well.
Furthermore, sources say that the weight savings will be significant for the base 740i model, dramatically below the 1900kg kerb weight and and potentially even the 1670kg of the current entry-level 5 Series. Without a doubt that if these figures are achieved, the new 7 Series will be one of the most dynamic luxury sedans in the segment, but we believe the numbers are slightly ambitious.
The plan to incorporate carbon fiber in load-bearing elements came from the research and development carried under the BMW i sub-brand which models rely heavily on the lightweight material.
Judging by the spy photos seen recently, the new 2015 BMW 7 Series will retain the same dimensions, about 5010mm long, 1815mm wide and 1425mm tall.
Under the hood, the new 7-series will pack a wide variety of engines, from six-cylinder diesel and petrol, to the upgraded 4.4 liter V8 (now 450 hp) and the 6.0 liter V12 petrol engines. BMW is also said to consider a 760 xDrive M Performance Model running a tuned up 4.4 liter twin-turbo V8 unit.
Without being confirmed at this time, the new ZF 9-speed automatic might make the cut.
The 2015 BMW 7 Series will be shown next year with an auto show debut most likely at the 2014 Paris Motor Show.
