The new 2014 BMW M3 saloon has been spied with new camouflage on its roof, that most likely means the prototype has a carbon fibre roof that will reduce both weight and the car’s centre of gravity for improved handling.
So far none of the M3 prototypes have had the roof disguised, they have all had the roof in the same colour as the body. As the production gets closer, it is most likely the prototype now has the carbon fibre roof under the new camouflage, just like the M4 coupe, which has been testing with a similar disguise.
The carbon fibre roof and other components are expected to cut the weight of new M3 by roughly 100 kg compared to the current model.
New M3 as well as the M4 is expected to use a new 3.0-litre turbo engine codenamed S55 with a power output somewhere between 400-450 horsepower.
