Starting with the 2016 models, BMW will no longer be making the Sport Line package available for the 4 series. Do not be sad, though. The reason for this is because all the Sport Line features will now be included in the standard kit.
Yes, you will basically be getting all the features that came with the Sport Line for free. If you opt for the 435i model, you will get even more freebies, including black kidney grilles, high-gloss black finishers for the air-intakes, 18-inch Style 397 wheels, and Matte Chrome exterior trims.
