BEST BMW M3is a high-performance version of the BMW 3 Series, developed by BMW's tuning branch BMW M. M3 models have been derived from the E30, E36, E46 and E90/E92/E93 3-series, and sold with coupé, sedan and convertible body styles. Upgrades over the "standard" 3-Series automobiles include more powerful and responsive (yet at times smaller) engines, improved handling/suspension/braking systems, aerodynamic body enhancements, and interior/exterior accents with the tri-color "M" (Motorsport) emblem.
