BMW the public a preview of the upcoming M135i in Concept form at the Geneva Motor Show three weeks ago. The M135i will be the next model introduced to the new line of M Performance Automobiles. Here are the first clear spyshots of the M135i production version currently being tested on the Nürburgring. In the photos, there are dual tailpipes and the trademark M Performance wheels that give us clues to its identity. The vehicle will most likely be powered by an N55 3.0-litre inline 6 delivering 320hp. The inspiration for this fastest 1 Series yet is the 1 Series M Coupe. The vehicle will be available both as 5-door F20 and as 3-door F21.
