Over the years we have heard BMW officials strongly deny M sport variants of the X5 and X6 time and time again simply because they can’t offer the same dynamics as the M saloon, roadster and coupes. And now, after a recent interview with Auto Motor und Sport, BMW M GmbH’s boss, Ludwig Willisch, has performed an about-face in perfect military style.

According to Willisch, ‘M’ prototypes of the X5 and X6 are both in existence and are currently undergoing testing at the Nurburgring Nordschleife. He continued that BMW M GmbH plans to complete both models by the end of 2009 and have them on the roads shortly after.
