According to leaked documents from a dealer presentation in the Netherlands, BMW is working on an M135i variant of the 1-Series which will debut next year.
Apparently the news is from the same set of documents that brought us the BMW M550d story yesterday. The report from Driving-Fun says the M135i will feature the 3.0 liter, twin-turbo six-cylinder unit dialed up to 320 PS (235 kW / 316 hp) - 14 PS more than in the previous 135i.
The car is also expected to get a full M division tuning treatment given that it's going to carry the M moniker in its name.
The BMW M135i is expected to debut in the summer of 2012.
