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.

The 4-series receives a revised suspension, LED headlamps, LED tail lamps, and subtle styling updates for the 2018 model year.
