"We'll be in the wind tunnel over the next 30, 45 days with the new prototypes as we do our evaluations on the submission cars, parts and pieces," Robin Pemberton, NASCAR's vice president for competition, said Friday at Preseason Thunder.
"Everybody seems to be pretty far along, and the changes that will come out of those will be based on parity due to the wind-tunnel numbers. We're optimistic that there will be some real race cars on race tracks probably in the second quarter this year doing some evaluation runs, if not before then. NASCAR president Mike Helton praised the cooperation between the carmakers, which decided with the sanctioning body's blessing to redesign the cars for next season. NASCAR.com
