Shanghai BMW M5 makes us yearn for Frankfurt

The appearance of the BMW Concept M5 at the Shanghai show may have been slightly diminished by the appearance of the thinly-disguised production car on the web some weeks ago, but we're still pretty excited about the prospect of a new version of arguably the world's greatest super saloon.

As expected, the concept gets the same 4.4-litre V8 twin-turbocharged engine which will feature in the production car potentially set to make its debut at this year's Frankfurt show.
