First prototype of upcoming 6th generation BMW 5-series, codenamed F10, has been caught testing in Munich. In one of your previous articles, we have showed a CGI, computer generated image, of how the next 5-series will look like. 

The new re-designed BMW 5-series is due to launch in 2010 and some of the main features include 8-speed auto with an AWD option available, Park Distance Control and an around-view monitor system.

As expected, the test mule is heavily masked and we really can't tell what BMW is hiding underneath.
