The upcoming BMW M5 has been photographed while undergoing extremecold weather testing. It will still be a while before we see an official image of the next incarnation of BMW's super sedan.

Details of the car, which will be unveiled at the 2017 Geneva Motor Show, are still sketchy. We understand that for the first time, you will be able to choose between all-wheel drive and rear-wheel drive versions. More manufacturers seem to be leaning this way for their performance sedans… Audi champions its Quattro system and Mercedes-Benz its 4Matic setup.

The engine of the new M5 is likely to be carried over from the previous model (4.4-litre twin-turbo V8), but will have higher outputsand better efficiency. The current M5produces 412 kW, but in special edition models such as the Pure Metal M5, it churns out 440 kW-plus. The new M5 hopes to hit the 450 kW mark and should have a 7-speed dual-clutch transmission.

While the spy shots show a heavily camouflaged M5, BMW says the design will follow the Gran Lusso design philosophy.
