Safety vs. Speed: 2017 Changes to the Chassis
The Evolution of the Stock Car While many fans decried the look of the Car of Tomorrow, the most significant thing about the COT was a part you couldn’t see: The Chassis. The first time I was around a stock car, I was surprised at how flimsy the sheet metal on it actually […]
Will Tire Limits Improve Racing?
Will 2017 Tire Limit Rules Require Harder Tires? Back in the day, the only thing that limited how many sets of tires you could use in Cup-level racing was your budget. It was different in the lower level series, because Cup teams that also ran XFINITY (for example) had much […]
Will Toyota’s New Nose Change the Cup Series Balance?
The unveiling last Monday of Toyota’s new redesigned race car for 2017 got a little lost between Junior’s wedding and Carl Edwards’ surprise ‘stepping back’ from NASCAR. But every time a manufacturer redesigns and engine or a body, it opens up a giant task for NASCAR. The Level Playing Field A […]
Can NASCAR Stop Secondary Accidents?
January is named after the Roman God Janus, who is the god of beginning, gates, transitions, time, doorways, passages and endings. How’s that for a job description? Janus is usually portrayed as having two faces: one looks forward and one looks backward. So I thought January might be a good […]
NASCAR’s Laser Inspection Process: Confidence and Accuracy
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 a thick booklet filled with detailed specifications, part numbers, measurements, tolerances and AutoCad drawings. Weekly […]
Is Stricter Enforcement of Pit Road Speed Limits Making Pit Road Less Safe?
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 Rudd came into the pits fast and locked his brakes. Rich died in surgery. To […]
NASCAR Drivers’ Risky Behavior and the Peltzman Effect
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 of a car quickly enough if they needed to. When HANS devices first became available, […]
The Digital Dashboard
Those of you of a certain age may remember these odd looking flat black vinyl things called ‘records’. Records are analog devices. A groove is cut into the vinyl. A stylus rides along the groove and translates the wiggles in the groove into an electrical signal, which is then transmitted to a speaker, which turns it into a vibration (which, when pleasant, we call “music”.)
Does Less Downforce Mean More Lift?
Last Tuesday, NASCAR announced aerodynamic modifications to be implemented for the Kentucky Speedway Sprint Cup race on July 11th. While the changes are (right now) only for that race, there’s every expectation that if they help reduce the dreaded ‘aero push’ problem, they may be extended (or modified) for other 1.5 […]
A Band Aid for NASCAR’s Tire Bleeding Problem
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.
