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.

Attention NASCAR teams: IMSA drivers available for Daytona!

NASCAR will be making its debut on the Daytona International Speedway road course next month, and there’s a big fan who’d like to join the historic weekend.

This fan actually has impressive credentials, too — a few thousand laps around the 12-turn, 3.56-mile layout that annually plays host to the Rolex 24 at Daytona in January.

In 2014, the winning GTLM team in the sports car endurance classic included IMSA Porsche driver Nick Tandy, who rabidly has followed NASCAR for more than 30 years since growing up in England.

So why not try racing NASCAR? Especially because Tandy has the weekend of Aug. 14-16 free.

He’s not picky, either — offering up his services on Twitter (as well as those of Porsche teammate Earl Bamber) for an ARCA, Xfinity, trucks or Cup ride.

Tandy’s affinity for American stock-car racing runs deep.

His first trip to the World Center of Racing was as a fan attending the 50th running of the Daytona 500 on Feb. 17, 2008. During Rolex testing in January, Tandy, 35, said he hadn’t missed a Cup race on TV in 15 years.

Among his favorite NASCAR drivers: the Earnhardts, Jimmie Johnson and Kyle Busch. When IMSA ran the Indianapolis Motor Speedway road course in 2014, Tandy stayed a few extra days at the Brickyard and bought Kyle Busch gear for himself and his children.

He briefly took the stage during a NASCAR weekend last October. After IMSA’s season finale at Road Atlanta, Tandy made a few demonstration laps and a burnout in his No. 911 Porsche before the Cup race at Talladega Superspeedway.

He also has some experience in stock cars, having raced Modified-type grass-roots series on England’s quarter-mile short tracks.

Couple that with a Daytona road course record that includes two consecutive podium class finishes (including last Saturday) and a sports car resume with 13 IMSA victories and an overall win in the 2015 24 Hours of Le Mans … and maybe a NASCAR team should take a look.

And Tandy isn’t the only IMSA driver who likely would be available.

Corvette driver Jordan Taylor, who won the 2017 Rolex 24 overall title with Jeff Gordon as a teammate (and the inspiration for his Rodney Sandstrom persona), also tweeted his availability for the weekend on the high banks.

Sports car veteran Andy Lally, a GTD driver with multiple class wins in the Rolex 24 as well as 38 Cup starts (he was the 2011 rookie of the season in NASCAR’s premier series), also hung out his shingle.

There also is AIM Vasser Sullivan’s Jack Hawksworth (who just won at Daytona last Saturday), the Englishman who teamed with Kyle Busch at the Rolex 24 in January and made an Xfinity start at Mid-Ohio last year with Joe Gibbs Racing.

Many sports car drivers (such as Taylor) already live in Florida, and many are hunkering down in the Sunshine State with IMSA returning to action at Daytona last week and Sebring International Raceway next week. Because of COVID-19-related travel concerns and restrictions, several IMSA stars who live outside the country are riding out the pandemic within a few hours of Daytona with nothing to do.

Why not a weekend at the World Center of Racing?

Over the years, scads of “road-course ringers” (including some Formula One veterans) have tried their hands in stock cars at Sonoma Raceway and Watkins Glen International.

How about considering the many sports car drivers who already have reached victory lane at Daytona by making a few right-hand turns, too?
