France says ‘significant’ engine changes coming

NASCAR Chairman and CEO Brian France said Tuesday on SiriusXM NASCAR Radio that modifications to the engines — which would likely bring a reduction in horsepower — are the next step in further enhancing the sport's on-track product, although he was unsure if such changes would be in place for next season. "We're going to make that happen, and that's part of the overall rules packages that we design that hopefully control costs, hopefully make the racing better," France said.

"The engine is an integral part of that. We also have to be in step as much as possible with the car manufacturers and where they're going with technology and different things. It all has to come together, and that's the next significant part of the rules package. … The engine will get a significant change. I'm not going to say (for) '15, but we are certainly sizing that up. It's very important for us to get that right."

According to representatives of NASCAR's three manufacturer partners, who took part in a conference call with reporters Tuesday, a potential reduction in engine horsepower is still in the very early stages. Sprint Cup Series engines generate 850 horsepower, and are built by five manufacturer-specific companies — TRD and Triad Racing Technologies (Toyota), Roush-Yates Engines (Ford) and Earnhardt Childress Racing and Hendrick Motorsports (Chevrolet).

Most of the changes made in recent years have focused on the cars, beginning with the rollout of the more brand-identifiable Generation-6 vehicle for the 2013 season, and an aerodynamic package that was further refined before this year.
