2012 BMW M5 teased again during Nardo high-speed testing

Seriously, BMW, enough with the 2012 M5 teasers. In addition to the buffet of spy shots that we've published, BMW debuted the production-looking M5 Concept in Shanghai and has released quite a few videos teasing the new M flagship sedan doing what it does best. Almost nothing has been left to the imagination at this point.

Who are we kidding? We can't get enough of this car.

This time around, we see the lightly camouflaged M5 doing high-speed testing at Italy's massive Nardo Ring – an important part of any M car development. As you can see by the driver's expressions, hitting the highest numbers on the speedometer is a piece of cake for the twin-turbocharged M5.

BMWBlog.com reports that the M5 will officially debut at the automaker's M Festival, held from June 23 to 26 to celebrate the 24 Hours of Nürburgring race. The car will make its grand auto show debut in Frankfurt this fall. Hit the jump to watch and hear the latest teaser.
