2015 Sprint Cup rules to feature reduced testing, less horsepower

12 Comments

As expected, NASCAR has released its 2015 Sprint Cup rules package to teams today. And as expected, it contains some major changes.

At the top of the list are a ban on private team testing at any tracks following the season finale at Homestead-Miami Speedway and a reduction in horsepower from 850-900 down to 725 with the use of a tapered spacer (which is already used in the Nationwide Series).

Additionally, the rear spoiler will be cut to six inches, giving drivers less downforce to work with on their cars.

In regards to testing, Goodyear will work with NASCAR and the Sprint Cup teams to select tracks for tire test sessions. Also, the “Preseason Thunder” sessions at Daytona International Speedway have been eliminated.

“The teams have asked for more productive sessions with all of us included,” O’Donnell told USA Today writer and NASCAR on NBC contributor Nate Ryan. “If we can have NASCAR, Goodyear and the race teams all together, it’ll be a home run.

“The second part is anytime you can minimize costs, that’s big. We think we’ve done both.”

The rules package comes after teams tested various aero configurations and power levels last month at Michigan International Speedway.

Drivers that took part in the Michigan session said they preferred a configuration with less downforce but retained the current 850-900 horsepower. It appears that those drivers will get some of what they wanted (the downforce part), but not all (current-level or additional horsepower).

However, O’Donnell thinks the new package will lead to what NASCAR’s been going after for some time now: A better on-track product on its 1.5-to-2-mile, intermediate ovals.

“We believe what will contribute to better racing is the ability to get off the gas in the corners,” O’Donnell said to Ryan. “If you’re able to slow down the straightaway speeds a bit, but really affect the speeds in the corners – where drivers have to make decisions on how much they want to get off the throttle – it allows for more passing in the turns, and it allows for tire manufacturer to really march toward a grippier tire.

“That will contribute to even better racing.”

Other changes on tap for 2015 include:

  • The addition of rain tires for Sprint Cup road course events with mandatory wipers, defogger and rear flashing rain light at the start of those events
  • An option to have a panhard bar in the cockpit to allow drivers to make suspension adjustments
  • A new video system for officiating in the pits that will have officials analyze cameras and software (some officials will still be in the pits for team communication purposes)
  • An online rule-book for teams with computer animation and 3-D illustrations

Today’s edition of NASCAR AMERICA will have more details on the 2015 rules package. You can watch it today at 5 p.m. ET on NBCSN and NBC Sports Live Extra for your online/mobile device.

Marvin Musquin to miss entire 2020 Supercross season

On Friday, Marvin Musquin announced on Instagram he will miss the entire 2020 Supercross season with a knee injury.

The injury was sustained earlier this week in a practice crash at the KTM test track when he overjumped an obstacle and landed hard.

It’s “not the kind of news I’m excited to share with you guys,” Musquin wrote. “I was really happy to be back on the bike riding after being injured at the end of the Motocross season and starting to train for Supercross. Unfortunately, I had an incident at the KTM test track and ultimately over-jumped a jump that had a very big impact on my legs when I landed, injuring my left knee.”

I had it evaluated by several doctors and it was determined that my knee required surgery. It’s devastating news to me as I was really looking forward to racing Supercross, but I will take the time needed to recover properly with my main focus being to return when I am strong enough to win races.”

Last year, Musquin sustained another knee injury in November that threatened his 2019 Supercross season. He was able to ride in the Anaheim 1 event and finished in the top 10. Musquin improved throughout the season, winning two races and finishing third in the points after making a determined charge.

Musquin missed the 2011 and 2014 Supercross seasons with ACL injuries.

A big thanks to my team @ktmusa for supporting me in this tough time. I feel terribly sorry for them and all my sponsors for not being able to represent them on the track for the 2020 AMA SX season. But we will be back 👊🏼
