stsjoe Posted December 19, 2006 Report Share Posted December 19, 2006 Mike, he must have lost part of the air dam at some point. Its wild (not funny) when one does that going sideways in NASCAR Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 19, 2006 Report Share Posted December 19, 2006 It's possible that there was something wrong with the body, but it looks to me like he was drafting really close at the top of a rise and the pickup of the front wheels caught the driver by surprise. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

BodybyFisher Posted December 19, 2006 Author Report Share Posted December 19, 2006 Well here is some more on that crash, pretty amazing: At Road Atlanta, the 911 GT1/98 of Yannick Dalmas made a spectacular backward flip, as did the BMW V12 at the same place in 2000, and most famously the Mercedes-Benz CLR at Le Mans in 1999. See this link: http://en.wikipedia.org/wiki/Porsche_911_GT1 AND this one : http://en.wikipedia.org/wiki/Mercedes-Benz_CLR ODDLY enough, I once saw a car behind me do this, it was a VOLVO and it got up to about a 45 degree angle and came down again, I have never seen anything like that, and don't know what caused it, or whether he hit the curb or anything.

Bruce Nunnally Posted December 19, 2006 Report Share Posted December 19, 2006 My favorite layman's explanation is that when a car body is designed to act as an inverted airplane wing, the velocity of the car provides downforce to help with cornering. However, if the front edge of the car lifts, such as when hitting a bump going over a sharp hill, then the shape of the car becomes a non-inverted wing and can lead to brief periods of flight. Lacking the proper stabilizers for controlled flight, the car just tends to crash. Lotus Esprits were especially good at this among road cars I have been told.

BigCat83 Posted December 20, 2006 Report Share Posted December 20, 2006 Modern race cars are very efficient at channeling air under their chassis. When that air flow is disrupted, downforce is lost and the car becomes airborne. Just like that Porsche. Looks like the drafting together with the uphill run disrupted that underbody airflow and the Porsche flew as a result. Link to comment Share on other sites More sharing options...
