Later,Daimler-Benz would publish a paper from wind tunnel research they conducted on their Gran Prix race cars.
The crux of what they learned,was that by enclosing the 'monoposto',exposed-wheel car,even with a greater frontal area,the overall drag was reduced.
In 1987,GM's Oldsmobile Division would use the same trick with AEROTECH,by enclosing a March Indycar chassis in a shrink-wrapped aero body,cutting drag by more than one-half and beating Mercedes' C-111 closed-course speed record at speeds up to 278-mph.(They considered higher speeds but A.J.Foyt was experiencing involuntary lane changes as gusts pushed him around on the Ft.Stockton,Tx Bridgestone/Firestone test facility track,same track where Car and Driver's test driver of my CRX was killed while at speed in a Renn Speed M-B.)
