Sixty-four drivers in 46 different car numbers ran for 37 full-schedule and 10 limited-schedule teams in 2019. But how did they do? And how does that compare to 2018? In my last post, I examined […]
NASCAR changed the ‘arms-length uncontrolled-tire penalty’ after pressure from fans and drivers who complained that the rule was too subjective. Does the new rule solve those penalty problems? Does NASCAR Need an Uncontrolled Tire Rule? […]
This is the time of the year when everyone takes one final look back at the last year before turning to think about the new one. So, in this last blog of the year, I thought I’d summarize the season in charts and graphs. […]
NASCAR has assessed 376 in-race penalties after 34 races. Do less-experienced drivers make more of these mistakes? Let’s check the data. […]
There Will Be Rules… The last time I was at the R&D Center, I was given a copy of the official NASCAR rule book for 1948. It was about a quarter of a page. Now there’s […]
The Purpose of Pit Road Speed Limits NASCAR implemented pit road speeding rules in 1991. The year before, Mike Rich, a tire changer for Bill Elliott, had been pinned between Elliott’s car and the car of Ricky Rudd when […]
The introduction of automotive safety innovations is usually accompanied by concern about the side-effects of those innovations. For example, when seat belts were introduced, people worried that the belts would keep them from getting out […]
There are three things you don’t mess with in NASCAR: engines, fuel and tires.
Tuesday, NASCAR handed down a P5 penalty – the penultimate penalty on the books – to Ryan Newman’s 31 team. Crew Chief Luke Lambert was suspended six races, fined $125,000, and Newman and his owner Richard Childress were each docked 75 points. The tire specialist and team engineer were suspended for six races as well. RCR is appealing the penalty, but I wager they’ve got an uphill battle.
NASCAR’s made its stand loud and clear in the last few weeks. Tire bleeding will not be allowed. If you persist in trying, they’ll come down hard on you. […]
Why Roof Flaps? Roof flaps (the invention of which I detail in my book The Physics of NASCAR) help keep cars on the ground. This is necessary because of Bernoulli’s law, which says basically that: Faster-moving […]
We’d been hearing rumors of penalties stemming from Kansas and everyone expected them to be announced Tuesday. Since penalties usually have some scientific component, I was sort of hoping for some new material. Tuesday came and went. Nothing. Wednesday, all heck broke loose as penalties were announced for the No 20 JGR car (engine issues) and the No 98 ThorSport truck.
The more interesting — and less discussed — penalty is the ThorSport/Johnny Sauter one. (It was a tough week for Wisconsin drivers). The team was docked 25 points, which is pretty huge for the Truck Series and the crew chief fined $10,000. (I realize that seems small when compared to the Sprint Cup Series penalties, but the Truck Series has correspondingly lower purses and salaries.) […]
