As many of us know already, the next generation 1-series (internal chassis codename F20) has been testing for some time now and has been in the wintery European north for cold climate testing. While its no secret that the next generation 1-series would likely get a 135i variant this is the first time that we are seeing a dual exhaust on the car on separate sides similar to other cars in the BMW range such as the 335i and 535i. This may simply be a move to bring the 135i exhaust setup closer inline with those cars or may in fact represent a hotter car such as a 135is model.
Compare with previously seen spyphotos which clearly had the dual exhaust cutout in the rear bumper but without both pipes in place. Something has changed in the wintery north
