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.

The fact that the most obvious example of this was on the 2 car and Brad Keselowski is rapidly taking over from Kyle Busch as most-love-to-hate driver in NASCAR may have brought the issue to the fore faster.

Dive! Dive! Dive Planes… on Stock Cars?

A persistent motorsports issue (and not only with stock cars) is the aerodynamic passing problem. You can’t pass without grip. Grip is a direct result of downforce. Downforce comes from two places: the weight of the car (mechanical grip) and the billions and billions of air molecules hitting the car (a.k.a aerogrip).

Knowing the COSMOS doesn’t mean you know NASCAR

Everyone’s favorite “planet” killer had a spare hour because COSMOS was pre-empted Sunday by the Coca Cola 600.  Astrophysicist Neil deGrasse Tyson edified us with some “NASCAR physics”. There were 43 drivers who had no problem taking the corners at more than 165 mph without skidding into the “embankment” and […]
