Drafting: Regular and Bump
I looked through the blog and realized that I haven’t really blogged about drafting. I’ve blogged about all the rules NASCAR’s enacted in the last couple of years to try to control drafting, but not drafting itself. So, with Talladega coming up, here goes Daniel Bernoulli: A Founding Father of Racing Sure, NASCAR…
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…
Using Drag and Downforce to Tailor Stock Cars to Different Tracks
Aerodynamics is complicated. Let’s just get that out of the way. But it’s not so complicated that we can’t understand what’s going on with just a little patience. Why 3D? Every wonder why they call it three dimensions? The reason it’s three is because I (or you) can denote any…
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…
2015 Rules Changes: Testing
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
@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
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.
The Arguments for Slowing Down the Gen-6 Car
It’s got to be a little frustrating that there are less than 90 days left before the start of the 2014 season and the rules package for the car isn’t set. Teams hope for a little more clarity following the open test at Charlotte Motor Speedway Monday. NASCAR’s put a…
Keeping Racecars on the Racetrack
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
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.
