These spy pictures show the most potent version of the new BMW 1-series, which is set to launch alongside the new three-door model later this year.
A BMW M insider confirmed to Autocar that the new model was likely to wear the M135i badge and would be part of the firm’s upcoming M Performance Automobiles line-up.
According to the insider the M135i model, pictured here in testing for the first time, was likely to be powered by the same 316bhp turbocharged 3.0-litre straight-six engine found in the BMW 640i.
Like all M Performance models, the M135i will also sport a whole host of chassis and styling tweaks as part of its makeover. Insiders say the model should be viewed as a three-door hatchback version of the current 135i coupé, with a more focused M-honed chassis and more muscular styling.
The spy pictures also reveal the look of the three-door 1-series for the first time. It gets a gently sloping roofline and a more angular rear glasshouse for a sleeker profile than the five-door model.
