Here’s proof that BMW is already working on the next generation 3-series. This 3-series mule was spotted in Germany.
At first it looks like another 3-series, but if you look closely you can see the modifications done to the current body. These modifications mean that the next generation 3-series will have a wider track and is most likely also longer. We expect to see the 3-series prototype with a next-generation body already end of this year. Stay tuned for more spy shots!
Next generation 3-series will debut earliest in 2011.

it looks more like the modifications indicate a wider track, not necessarily “wider” wheelbase.
