BMW M3 Powered By A Mazda Four Rotor Engine

The BMW M3 is a high-performance version 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. Common upgrades over the "standard" 3-Series automobiles include more powerful and responsive (yet at times smaller) engines, improved handling/suspension/braking systems, more aggressive aerodynamics/body, and multiple interior/exterior accents with the famed tri-color "M" (Motorsport) emblem.
The Mazda Wankel engines (a type rotary combustion engine) are family car engines derived from experiments in the early 1960s by Felix Wankel, a German engineer. Over the years, displacement has been increased and turbocharging has been added.
