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.

Final 2023 Rolex 24 at Daytona results, stats

0 Comments

DAYTONA BEACH, Fla. — The 2023 Rolex 24 at Daytona overall results were all streaks: two consecutive victories in the endurance classic for Meyer Shank Racing and three in a row for Acura.

And Helio Castroneves became the second driver to win three consecutive Rolex 24s and the first to win in three straight years (Peter Gregg won in 1973, ’75 and ’76; the race wasn’t held in ’74 because of a global oil crisis).

Starting from the pole position, Tom Blomqvist took the checkered flag in the No. 60 ARX-06 that led a race-high 365 of 783 laps with co-drivers Castroneves, Simon Pagenaud and Colin Braun.

Meyer Shank Racing now has two Rolex 24 victories and the 2022 championship since entering the premier prototype category of the IMSA WeatherTech SportsCar Championship in 2021.

“I think what’s so special about this team is we are a small team compared to some of our opponents, but the atmosphere, the way we work, enables people to get the best out of themselves, and I think that’s why we’re such high achievers,” Blomqvist said. “I think there’s no egos. It’s a very open book, and that just enables each and every one of us to reach our potential. I think that’s why we’ve achieved so much success in really a short time at this level of competition.”

It’s the 16th IMSA victory for MSR.

The 61st running of the Rolex 24 at Daytona marked the debut of the Grand Touring Prototype category that brought hybrid engine technology to IMSA’s top level.

In other categories:

LMP2: James Allen passed Ben Hanley on the final lap and delivered a victory in the No. 55 ORECA by 0.016 seconds. It’s the second IMSA victory for Proton Competition, which last won at Sebring in 2012. It was the first Rolex 24 victory for Allen and co-drivers Gianmaria Bruni, Fred Poordad and Francesco Pizzi.

GTD Pro: Cooper MacNeil won in the last start of his IMSA career as the No. 79 Mercedes-AMG GT3 scored the first Rolex 24 at Daytona for WeatherTech Racing and the team’s fourth career victory.

MacNeil, who co-drove with Maro Engel, Jules Gounon and Daniel Juncadella, earned his 12th career victory and first at the Rolex 24.

“Winning by last IMSA race is tremendous,” MacNeil said.

GTD: The No. 27 Heart of Racing Team delivered the first Rolex 24 at Daytona for Aston Martin, which has been competing in endurance races at Daytona International Speedway since 1964. Drivers Marco Sorensen, Roman De Angelis, Darren Turner and Ian James (also the team principal) earned the victory in the English brand’s 13th attempt.

It’s also the first Rolex 24 at Daytona win for Heart of Racing, which has seven IMSA wins.

LMP3: Anthony Mantella, Wayne Boyd, Nico Varrone and Thomas Merrill drove the No. 17 AWA Duqueine D08 to victory by 12 laps for the team’s first class win in IMSA.
