2015 Rules Changes: Testing

by:

One of the biggest changes NASCAR has instituted for the 2015 season is eliminating individual team testing at any tracks. In 2014, teams were limited to four tests and were not allowed to test at tracks that were included in the schedule. NASCAR may run some limited tests, but they won’t be having the week-long marathon that was Daytona Speedweeks.

2015 Rules: Track Records I – The Example of Charlotte

by:

@NASCARRealTime, @TheOrangeCone and @CircleTrackNerd had an interesting dialog when the 2015 rules were announced. They were debating whether the track records that are now standing are going to be essentially locked into history. The debate ended with an appeal to me and Goody’s Headache Powder.

Firewalls and Aerodynamics

by:

My friend at the Milwaukee Journal Sentinal, Dave Kallman (whose online column should be a regular read for race fans) asked about the confiscated firewalls from the Number 11 car at Indy. That reminded me of the first NASCAR race I was supposed to attend as research for my book The Physics of NASCAR. That was California in 2007. I was to follow around the number 19 car, at that time driven by Elliott Sadler and crew chiefed by Josh Browne.

Keeping Racecars on the Racetrack

by:

Ryan Newman escaped NASCAR sanctions for his comments immediately after being discharged from the infield care center at Talladega.

“They can build safer racecars, they can build safer walls, but they can’t get their heads out of their asses far enough to keep them on the race track and that’s pretty disappointing, and I wanted to make sure I get that point across,” he said. “You all can figure out who ‘they’ is.”

From the Lab Notebook: Las Vegas and the Mysteriously Missing Oil Tank Cover

by:

As we head for Las Vegas this weekend, I thought I’d repost on of my most popular posts from stockcarscience.com on 3/5/2008 since the redirects for the old stockcarscience.com site don’t work reliably. The post is about Carl Edwards’ 2008 win at Las Vegas when the team was subsequently fined for having their oil tank cover lid askew at the end of the race. I have edited the post extensively, adding some new information and better graphics.
