Don Schroeder,who tested my CRX at Chrysler was killed on this track when he lost control of a RennTech V-12 Mercedes.
When A.J.Foyt was going for the record in the long-tail Olds Aerotech he claimed that is was very difficult to keep the car in its lane,And that was with tunnel-ram ground-effects downforce underbelly.
I went to Ft. Stockton in 1997 and they said it was very windy there and it really impacts the number of days when people can test.
It's only my opinion, that the tail cone on the EV-1 allowed the low base pressure of the wake to underride the tail and use it as a moment arm to improve traction over the rear axle.
The "six-pack" of extra batteries on the floor of the passenger side would have added downforce at the front.
Just a guess.
