Before it had introduced the 6 Series, built from 1976 to 1989 and then reintroduced in 2003, BMW had the New Six (E9) to fill the coupe gap in its lineup. Launched in 1968, the E9 survived for eight years, in which several versions were created with engines ranging from the twin-carb, 2.5-liter to the fuel-injected 3.2-liter. Stunningly beautiful in standard guise, the E9 spawned a downright aggressive, yet still gorgeous, race car toward the end of its life. Known either as the 3.0 CSL or the 3.5 CSL and often dubbed "Batmobile," this beefed-up monster marked the beginning of a very special era for BMW. One that would cement the automaker’s image as a race car manufacturer.
