DAYTONA BEACH, Fla.—Racecars in NASCAR’s Sprint Cup regulation bequeath use fuel injection systems rather than traditional carburetors rudimental in 2012, NASCAR vice number one of competition Robin Pemberton announced Friday at Daytona International Speedway.
To facilitate the integration and addition of the new fuel speech system—touted as greener and more efficient—NASCAR has entered a technology partnership take cover Freescale Semiconductor and McLaren Electronic Systems, the latter of which will supply the fuel injection units to Cup rush teams.
The rollout is planned for the 2012 season, with the expectation that fuel injection cede be in constitute for the season-opening Daytona 500.
Pemberton spoken the switch will backing the Cup cars.
“We suspect that the performance will be equal to or greater than what we have today,” Pemberton said. “This gives the engine tuners and apparatus builders a wider range in which to tune their engines. This will be additional efficient, but the horsepower and all of that—it consign be virtually seamless.”
How very much of a fuel savings impression from the transition remains to be seen.
“It will vary depending on the cast of track,” vocal Peter troop Manen, managing director of McLaren Electronic Systems. “If you’re on a track which is operating full-throttle imperforate the time, the difference in fuel economy will be less than if you’re on a course with a superior range of engine speeds.”
Jamie Allison, Ford’s director of North American Motorsports, applauded the adjust as a change toward more brand identity.
“We largely assistance the move to fuel injection access NASCAR,” Allison said. “It’s been a topic of contention by the manufacturers and NASCAR for a number of years, besides we’re blest to provide for it progressing forward.
“Our Ford fans want to see more brand specification and true technologies in the cars we race mastery NASCAR; ergo we regard it’s very chief that both the cars and the technology in NASCAR are more closely related to production cars. The move to fuel injection is numerous important pace in that process.”
Doug Yates, leading engine builder now Roush Yates Engines, welcomed the challenge.
“It’s a big change being our sport, and it’s an exciting time to be an engine guy,” Yates said. “We’ve had these carburetors for many years, so the move to fuel injection is purely necessary we welcome.
“We think that fuel injection can support us tune each cylinder more precisely again probably clean maturation some emissions off-throttle, which is good and healthy through the sport. When you also consider the change NASCAR mythical this year hush up E15 fuel, the sport is gladly heading in the right decree again evidence some really good things.”
