Spy Video: BMW M3

BMW M3 at the Nurburgring

BMW aficionados know that once an M car goes into production that’s it, there will not be any technical upgrades during its lifecycle.

And since the current M3 was launched two years ago a new one is not expected until at least 2013.

So then why is BMW testing an M3 around the Nurburgring in 2009?

And why does the subject sport a very basic-looking rear wing, a front bumper splitter and what appears to be a roll cage?
