Click above for high-res gallery of 2010 BMW 5 series spy shots

The current BMW 5 series is a bit awkward in appearance, but it appears that the propeller brand will be getting away from the Bangle-inspired creases and concavities of the current model with the car’s next redesign. Caught testing on the ‘Ring recently, the next-gen 5 series is sporting a new grille with nostrils large enough to drive a 1 series through. Seemingly inspired by the mondo nose of the BMW CS concept, the new 5 series will also apparently sport a smoother overall shape that gets us back to BMW sedans of the past. We dig it, at least in prototype form. Check out more angles in our high-res gallery of spy shots below.
