To help it become a better handler and to increase efficiency, weight loss is due for the new 7 Series, and will be delivered thanks to the use of aluminum and carbon fiber. Carbon fiber was used extensively in the new BMW i3 and i8, and the 7 Series will be the first ‘mainstream’ BMW to benefit from lightweight material, which has only been used in some BMW ‘M’ cars.
Powertrain options will be plentiful, with a range of six, eight and twelve cylinder gas and diesel engines. To compliment the weight loss, a 12-cylinder hybrid may be offered to give the big powerplant an mpg boost.
The new 7 Series is expected to debut at the Frankfurt Motor Show in 2015.
