Changing Manufacturers: More than just Decals?
I’d Rather Fight Than Switch If you remember what commercial that was from, then congrats. You are — like me — old. It used to be that an owner was loyal to his manufacturer to […]

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 […]

How NASA Research could end NASCAR Engine Failures Due to Trash on the Grille
For want of a nail the shoe was lost. For want of a shoe the horse was lost. For want of a horse the rider was lost. For want of a rider the message was […]

How Tracks Take and Lose Rubber
The two words we heard most frequently last week in Pocono (after “still raining”) were “green racetrack”. Rain doesn’t just delay racing. When the race is finally run after a rain delay, it’s run on […]

Does Grass Pose a Danger to Racecar Drivers?
Now that most tracks have put SAFER barriers on any possible surface, it might seem like racetrack safety is a done deal. That’s not what we’ve heard this week at Daytona, though. Some of the drivers […]

NASCAR and Energy Efficiency
It never fails. When I give a talk about The Science of Speed at a University science department (as opposed to a talk for the public), someone will ask “How can you advocate for NASCAR? They’re the biggest waste of gasoline.”

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. […]

Do Tires Affect Gas Mileage?
When winning means a few hundredths of a second, nothing is too small to be ignored. I’ve talked a lot about energy and the importance of using it as efficiently as possible in racing. Gasoline provides a […]

Are SAFER Barriers Everywhere the Solution?
TL;DR: No. As the extent of Kyle Busch’s injury Saturday evening at Daytona became evident, Twitter erupted in angry calls for SAFER barriers to be put up on every wall at every track. An interesting division […]
