From an SAE Paper from the latter 1980s,the F1/Indycar body was:
*Cd 0.24 by itself.
*Cd 0.54 with wheels.
*Cd 1.2 with wheels and wings.
*They were turning laps at Indy at 235-mph.
*At 150-mph their dynamic 'weight' was 5,000-lbs,for a car of 1,500-lb static weight.
*And yes,they could easily race inverted.
