F1 technology hit the human drivability singularity sometime around the 1980's. If ground effect were left unchecked, and the turbo motors and qualifying tires lasted more than a single lap, a human would not reliably be able to extract the maximum capabilities of the car. G-forces aren't the sole matter, as one thing… » 12/02/13 4:05pm 12/02/13 4:05pm

Raphael, thanks for the recommendation! If there's anything I can help clarify regarding aerodynamics, vortices, downforce, etc., let me know. Aerodynamics isn't exactly a very intuitive science, and at times, it's practically black magic. » 11/26/13 12:09pm 11/26/13 12:09pm

Aerospace engineer here. Some vortices are good, some are bad. Generally, vortices off of the wings (especially noticeable off the rear) aren't desirable. A strong tip vortex means a lot of energy is being lost there in drag. It's a good indicator of the pressure differential at the wingtip, but it also means it's… » 11/25/13 10:52am 11/25/13 10:52am

Technically, it was the Ferrari 250 GT Drogo, built on a 250 SWB chassis. It was built because Enzo wouldn't sell a 250 GTO to a customer, so the customer commissioned this special Ferrari, with low drag bodywork by Piero Drogo. If I recall, it was able to run several kph faster at Le Mans than the 250 GTOs. » 10/09/13 5:01pm 10/09/13 5:01pm

Just to clarify, the RX-7 incident happened as a result of mismatched lug nuts, at an autocross event in south GA. A supplier sent him wrong ones They were imperial threaded nuts on metric lugs, which threaded on just far enough to make it seemed torqued, but when he put a high lateral load through the wheels, they… » 6/11/13 1:41pm 6/11/13 1:41pm

So this showed up at an autocross yesterday - Ford Focus RS

At the Atlanta Region SCCA Solo event, some intrepid young chap from Mexico showed up in one of these. This is apparently one out of 100 cars imported to Mexico, and he happened to be out our way and heard of an autocross going on. Our Solo Chair took this shot. Yeah, I think we do Solo right. » 6/10/13 10:27am 6/10/13 10:27am

While this might be the fastest supersonic ejection, it isn't the first. That "honor" goes to Lt. Cdr. Ray Hawkins, a Blue Angels pilot, who ejected in 1953 from his aircraft that was in an uncontrollable supersonic dive. http://www.blueangels.org/NANews/Articles/Oct53/Oct53.htm » 10/12/12 3:23pm 10/12/12 3:23pm

That's actually a Red Bull RB1, with some modifications for the 2010 aero rules. Notice the position of the exhaust, the gills on the sidepods, and the mirrors mounted on the turning vanes. Both the RB5 and 6 had very low mounted exhausts to aid the diffuser. » 1/08/11 5:15pm 1/08/11 5:15pm
