While some sources say a BMW 1 Series M is headed for production, the team at Inside Line continues to insist that no such car is in the cards – sort of. You see, rather than a super high performance M version, Inside Line says a to look for a 135is.
The 135is would get a more powerful version of the twin-turbo N54 straight-six engine with a tighter suspension setup and likely some mild design tweaks. In the 335is, the same engine makes 320-hp and 332 ft-lbs of torque with an overboost function that will deliver short bursts of 370 ft-lbs of torque. We can imagine a 7-speed dual-clutch transmission will be optional, as will plenty of M Sport goodies.
