NASCAR considering reducing horsepower to Cup cars next season:
NASCAR is planning on making significant engine package changes in 2015
to extend the life of Sprint Cup powerplants and reduce horsepower. And
along with engine changes, there likely will be aerodynamic and tire
changes for the Cup cars in 2015 as well. That's the word from NASCAR
Vice President of Competition and Racing Development Robin Pemberton.
Pemberton said the sanctioning body has had four meetings so far with
representatives from Chevy, Ford and Toyota and race teams about how to
implement those changes. No consensus has been reached yet, according
to Pemberton, but discussions are ongoing in advance of making the
changes for next year. Although Pemberton declined to specify how many
horsepower NASCAR is looking to cut, sources familiar with the
discussions said the reduction would be in the neighborhood of 75 to 100
horsepower. Currently, NASCAR Sprint Cup Series engines make about
860-900 horsepower at most tracks. Discussions are still in the early
stages, Pemberton said, but given the fact that there are so few engine
suppliers now, they will need plenty of lead-time to make changes for
next year.
Among the options being discussed are reduction in engine displacement and changes to throttle body size. Sources familiar with the discussions say that Chevy and Toyota are pushing for a reduction to 5.0-liter engines, while the Ford camp is pushing for the use of tapered spacers, such as are used in the NASCAR Nationwide and Camping World Truck Series engines. Pemberton said any change in the engine package likely would necessitate other changes as well.
"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. Goodyear ... we have the same tire patch as when we started.(FoxSports)(3-23-2014)
