BMW has released a teaser of the upcoming BMW F10 M5. The video shows a tunnel in which the lights go on. From the background a car drives close to car and passes. It is hardly impossible to see which car passes by, but the Germans suggest that it is the new BMW F10 M5 to be revealed at the Shanghai Motor Show 2011 on April 19th.
The displayed M5 will be a concept and not the full release package which includes the 4.4 liter V8 BiTurbo engine producing 600hp. The official version will be revealed at the IAA Frankfurt Motor Show in September.
