The 2013 Cup car is the result of more than two years of collaborative efforts between the manufacturers and NASCAR. The cars more closely resemble their respective manufacturer models on the showroom floor.
“We commend the manufacturers and our team at the R&D center on all the hard work they’ve put into this new car,” said Robin Pemberton, NASCAR's vice president of competition. “With all the designs and surface areas of the car now approved, manufacturers can now move forward with building the components needed to outfit their cars.
"The wind tunnel testing we’ve had with the manufacturers over the past several months has given us the timely and necessary data we needed to come to this confirmation. We believe the new car is going to be a milestone opportunity for our sport, one that our fans will embrace."
