More period footage, this time featuring the Mighty BMW CSL Batmobiles racing against various types of Porsche 911 (mainly 934's and 935's) in the Seventies. Surprisingly, considering the size of the wings and tyres on these cars, how much they moved around compared to todays GT racers, but then the CSLs were alleged to have upwards of 750BHP in turbocharged form. The video features a very nice slow motion section of a Batmobile getting air.
