The 4-Series (formerly 3-Series) has long been the standard-bearer in one of the industry's most competitive segments. BMW offers an impressive combination of styling, performance, and luxury features for a German luxury coupe priced from the low forties. Offered in RWD and AWD versions, the 3-Series model range includes multiple models with alphanumeric designations corresponding to their drive train. The 428i equips a turbocharged four-cylinder rated at 240-bhp whereas 435i models include the traditional inline-6 rated at 300-bhp. Most BMW models includes a healthy list of driver aids and available technology, but some common items like heated leather seats require hitting the option list.

New engines force an updated nomenclature. Four cylinder models are now 430i (formerly 428i), whereas six-cylinder engines become 440i (formerly 435i).
