NASCAR reportedly considering Sprint Cup engine horsepower reduction in 2015

11 Comments

In what could be the biggest of several potential changes, NASCAR officials are reportedly contemplating a reduction in Sprint Cup racing engine horsepower in 2015.

According to a report by FoxSports.com, NASCAR vice president of competition and racing development Robin Pemberton said the sanctioning body is looking at ways to prolong the overall life and durability of Sprint Cup motors.

While that would be seen as a performance issue change, it could also be considered an economic change, with teams not having to spend as much as they do yearly on developing and building motors.

“It’s as much getting more use out of engines as it is (reducing) horsepower,” Pemberton said. “They kind of feed off of each other. There’s no guarantee horsepower may or may not do anything for the quality of racing, but it will allow us to do other things.”

According to the Fox report, NASCAR officials have had a series of four meetings each with Chevrolet, Toyota and Ford representatives to develop guidelines on how to reduce horsepower.

Whether that means smaller engines, more fuel efficiency (which is also likely one of the key goals of the potential changes), or perhaps even some type of restrictor plate usage remains to be seen.

The goal, according to sources FoxSports.com spoke with, is to reduce power by as much as 100 horsepower, or roughly as much as 15 percent

That would drop the power level that current Sprint Cup motors pump out from 850 to 900 hp to somewhere in the range of 750 to 800 hp, which is what motors were producing back around 2007 and 2008.

“It’s not fully appreciated the fact that we’ve had the same engine for basically 25 or 30 years and it’s at 850 or 860 horsepower, where it used to be 500,” Pemberton said. “And we are at the same race tracks where we used to run 160 (miles per hour) we’re now qualifying at 190 and running 213 going into the corners. There’s been a lot of engineering and gains made across the board.”

Scaling back power is not necessarily seen as a safety issue, but more as a means to further control costs that continue to spiral upward each season.

“It’s some about economics, and there are some who think that if you knocked a little bit of horsepower out, it could put you in a position to make the racing better,” Pemberton said. “But there’s a lot of things that go into it. There’s the mechanical grip and the tire grip and the aerodynamic grip and engine horsepower.

“Every one thing you change, you have to adjust everything around it to make it right. There’s some sort of balance in there. So, if you do a horsepower change, there’s a better than not chance that you will have to adjust aerodynamics, and that may give you the ability to adjust tires. So it’s a three-legged stool. You just have to work on them all.”

Initial response from the series’ three manufacturers has been positive, according to the Fox report.

“If it truly does potentially help the racing and then help durability on the back end, I think it’s not a bad thing to do,” said Pat Suhy, NASCAR Group Manager for Chevrolet Racing. “It’s probably going to be a fairly extensive change, a bigger change than first imagined. … I’m in favor of change when it can make things better, so I’m hopeful that it can actually make things better.”

Added David Wilson, president/GM of Toyota Racing Development, “From our perspective, the healthy thing about this is that NASCAR is working not only with the manufacturers, but all of the engine builders. And we have had a dialog with NASCAR for some time. Just the process itself is absolutely correct. It’s refreshing. We feel as stakeholders in the sport, we have a voice.”

Ford Racing director Jamie Allison agreed.

“We are actively involved with NASCAR on strategic competition and business considerations and support NASCAR’s efforts to work with the manufacturers to continually evolve the sport,” Allison told Fox.

The Callaway Corvette GT3 is coming to America, in PWC

Pirelli World Challenge has been in need of some good news from a car count standpoint early into this offseason, and receives it Monday with confirmation Callaway Competition will bring its GT3-spec homologated Corvette C7 GT3-R Stateside next season.

The withdrawal of the factory Cadillac Racing program after PWC’s season finale in Sonoma in September has opened the door for the factory-blessed Corvette C7 GT3-R to run in North America, because Cadillac’s ATS-V.R has been the lone GT3-spec car under the General Motors awning for the last three seasons, while the Callaway Corvette has raced only internationally.

Reeves Callaway has been on site at the tail end of the PWC season to survey the opportunity and now a deal has been struck for a factory effort to run next year, before the Callaway Corvette program becomes a customer effort in 2019. This follows the same timeline as Acura did with its new NSX GT3 this year to run it as a factory program in 2017 before shifting to customer efforts in 2018.

“Joining the Pirelli World Challenge has been a long term objective for Callaway Competition,” Callaway said in a release. “Now the field is a roll-call of the most capable sports cars from every country. To do well here, you must beat the best in the world. What better way to showcase our iconic American car?

“For 2018, we will run a Callaway factory team to give us the best chance of continuing the championship record the Corvette has achieved in international competition. For 2019, we will not race against our customers, but provide high-quality support to them in the tradition of other manufacturer customer racing support programs.”

“For several years fans have asked when they would see the Callaway Corvette GT3 run in the Pirelli World Challenge,” added Greg Gill, President and CEO of Pirelli World Challenge. “The wait is over and we are very pleased to announce the arrival of the Callaway Corvette GT3 for the 2018 season.”

The Callaway Competition USA Corvette C7 GT3-R will be unveiled and both full season drivers announced at the Performance Racing Industry show in Indianapolis on December 7 at the Pirelli World Challenge booth. Following the unveiling event, the car will be on display for the remainder of the trade show. Details of the presentation will be announced in the coming weeks.

Callaway’s confirmation comes amidst the likely drawdown of potentially nine or 10 cars that raced in PWC’s GT and GTA ranks either all season or most of it in 2017, among at least five manufacturers. That’s not to say those losses can’t be recouped elsewhere on the grid, over the next several months before the St. Petersburg season opener in March.

PWC will hold its annual state of the series and competitor meeting to finalize the next year’s plans at the PRI show as well.
