Transmission options include an eight-speed automatic for the 330i and M340i models and a six-speed manual available exclusively for the M3 variant. Both rear-wheel drive and BMW's xDrive all-wheel drive systems are available depending on the trim. Noteworthy features include a suite of advanced safety technology as part of BMW's Active Guard system, a standard 8.8-inch or optional 10.3-inch infotainment screen, Apple CarPlay and Android Auto compatibility, and optional upgrades like a head-up display and gesture control. For the 2021 model year, the M3 variant was resurrected, sidetracked wireless Android Auto, and introduced mild hybrid technology in some models.
