Though it hasn't released an image of the F90 M5 without camouflage so we can see the gorgeous sheet metal, BMW has already confirmed that the upcoming 5 Series hot rod will have a few crucial features like an eight-speed automatic transmission, a twin-turbo V8 and perhaps most crucially, an xDrive all-wheel drive system that will be one of the more cutting-edge xDrive derivatives in the brand's history. This doesn't exactly make the F90 the first M car to have all-wheel drive, M versions of BMW X SUVs hold that title.

What is new about this M5's xDrive system, however, is that it reserves the ability to switch between all-wheel drive and rear-wheel drive at the touch of a button. Something similar was previously seen on the new Mercedes-AMG E63 S and stands as a piece of technology that's hard not to get excited about because it combines the best of both worlds.

Now, drivers in cold and wet regions can drive their sedans year-round and don't have to settle for BMW's quattro-endowed competitor, Audi. Even drag racing performance and lap times are likely to get better by using the four contact patches as means of torque delivery, but as an M5, the F90 must preserve the ability to hang the rear end out and reserve the driver the right to use throttle application to balance the car through a corner. All of that is now possible within a single chassis, and enthusiasts understand that significance. Not everyone else does, though, so BMW has introduced this clever little advert to give the unaware a frame of reference for the technology using a toy we can all relate to.
