The 2017 BMW 3-Series is part of the iconic executive sedan's sixth generation (F30). Offered in four trims—320i, 330i, 340i, and the high-performance M3—each has unique engine options ranging from a 180-hp turbocharged four-cylinder to a 425-hp twin-turbo inline-six. All versions come with RWD as standard, with xDrive AWD optional. The transmission choices are either a slick-shifting 6-speed manual (no-cost option on M3 and 340i RWD) or an 8-speed automatic. Tech features include the iDrive infotainment system with 6.5-inch central display, Bluetooth, a nine-speaker sound system, and BMW's ConnectedDrive services. Major updates for this year include a slight power bump for four-cylinder models and wireless charging for compatible smartphones. Across all trims, this 3-Series shows off BMW's superior ride and handling balance and excellent build quality.
