The next generation BMW X5 has been spied winter testing in Sweden.

The F15 X5 will be based on a lighter chassis along with sleeker looks and matched with a range of engines with better fuel economy over the current model.

Powering this new range of X5 will be a range of turbocharged engines, including the usual 6 cylider engines and perhaps a turbocharged v8 in the X5M.

This is unlikely to be in production until early 2014 so we expect to see this through the year in different stages of undress.
