In the Zone: Goodyear’s New Tire Design

Kansas marks the second appearance of Goodyear’s “Multi-Zone Tread Tire”, which was first used at Atlanta Motor Speedway over Labor Day weekend. Stop for a moment to appreciate the challenge Goodyear has to face each […]

Notes on Respect and Fines

A short note on Denny Hamlin’s comments on the Gen-6 car and subsequent fine.

I’ve talked to a lot of the people in the trenches involved in designing and creating the Gen-6 car. That includes people from manufacturers and teams. All of them have said that the development of the Gen-6 car is a major sea change for NASCAR. This is the most collaborative that NASCAR has been with introducing a new car in some time. Manufacturers and teams were consulted and they all feel that their opinions mattered and were taken into consideration. This was a very, very different process than the COT introduction, which was designed by NASCAR and plans delivered to teams. […]

Why Safety Takes Time

I suppose it’s really our own fault because of the way we teach science.

We give you labs constructed to get the right answer on the first try. We have you measure things you already know the value of. We tell you that things were invented by a single person on a specific date. […]

Cautions: A New Low for NASCAR

At the start of the season, the big news was that cautions were remarkably down from last year. As I showed, this isn’t a new trend – it’s a continuing trend since 2007. Since the season’s data are now complete, I thought it was time to revisit the data. […]

NASCAR Concussions II: A Screening Test to Avoid Relying Entirely on the Driver

I was lucky enough to speak with Dr. Mark Lovell, an innovator in neurocognitive testing inbetween talks at a conference he was attending. Dr. Lovell came to my attention as the developer of the ImPACT (Immediate Post-Concussion Assessment Testing) test, which was one of the tools used to evaluate Dale Earnhardt, Jr.’s concussion. […]

Aerodynamic Downforce: A Passing Fad?

The question of why it is so difficult for cars to pass each other at 1.5 mile and 2 mile tracks is getting more and more attention. Carl Edwards put it succinctly:

“I firmly believe, and NASCAR hates it when I say this, that we should not be racing with downforce, sideforce and all these aerodynamic devices. We do not need splitters on the race cars and giant spoilers. I have not been around long enough to say something definitely, but it is pretty common sense: if all the cars are very similar and all the drivers are within a tenth of a second of each other but are relying on clean air and downforce, then by definition if the guy in front of you is disturbing the air then your car is not going to be able to go as fast as it could in clean air.” […]
