The news says lazy boy had a issue with it not being a lazy boy.
Efficient, yes. That does not make it the best format for racing, and I never said it would. Clearly efficiency is not always the fastest way around a track or spoilers wouldn't work as clearly they make drag.
But given infinite traction and equal HP, FWD would be faster. You just have to bend the physics rules for lots of traction
Frontal area is only one element. the shape determines the Coefficient of Drag.
Even stranger is near supersonic speeds the object should have a narrowing near the middle, kinda wasp like.
Because it's easier to one shot swap the whole thing than piece it together. They also have an easier time finding the cars. There are lots of little things to think about if you turbo the na.
Try stopping by the http://www.zcarchat.com or one of the Zoom meetings. There are a few old racers that stop by and could answer some questions.
I've also heard good things about http://www.whiteheadperformance.com/
