BMW testing new turbo engine in a 5 Series

[szumszer]

it was a nice run for bmw w/all those N/A petrol engines, but i guess there is only so much that can be done, especially when its major competitors use turbo and supercharger enhanced engines; but after all so much of past bmw racing history is associated w/tubo engines that it would not be a shame if one of the M cars was to be powered by a turbocharged powerplant
