Champion race driver Brian Redman tells us all about the ultimate BMW 3.5 liter CSL he co-drove to victory at the 1975 Daytona 24 hour endurance race and the Sebring 12 hour race in 1976. He describes the sound and characteristics of the car as we examine details and see it blast around the track. For a race car that’s over 27 years old, it still compares well with current BMW’s. Even for today this car has very wide racing tires, wild looking aerodynamics, and an incredible sound. The mother of all six cylinder BMW engines!
