NASCAR to Release 2015 Rules Package This Week

Changes are coming to the sport of stock car racing – and don’t expect it to be bigger engines.

According to a report by Motorsport.com, the sanctioning body will release the new rules package for the 2015 NASCAR Sprint Cup Series season this Tuesday (Sept. 23).

Expected changes in the new rules package include such major items as a reduction to the height of the rear spoiler of the Toyota Camry, Chevy SS and Ford Fusion racecars, as well as a much-reported reduction in horsepower to the power plant under the hood of all Sprint Cup Series cars.

The engines will be reduced by 125 horsepower, which should help to allow for more passing and more competitive racing with the new aerodynamics package and Gen-6 cars. The current engines run Sprint Cup Series generate 850 horsepower and are expected to be reduced to 725.

The engines suppliers for each manufacturer – Chevrolet with Hendrick Motorsports, ECR Engines; Toyota TRD with Triad Racing Technologies; and Ford with Roush-Yates Engines – have supported such a change.

In an interview with SiriusXM NASCAR Radio, when the engine horsepower reduction was first discussed back in April of this year, NASCAR CEO Brian France told Dave Moody, “The direction that we’re going allows us not to have to make any significant chances in the future. We know exactly what we’re trying to do with the rules package. We think the (Chase) format is something we can build on for the next 10 or 15 years, or longer. We don’t want to change things just because we feel like it. It’s always difficult.

“So I love the general direction we’re at. We’re past the majority of the changes, and now we can build on where we’re at.”
