NASCAR slates fuel injection test at Daytona

By Pete Pistone

NASCAR has added another electronic fuel injection test on November 15 at Daytona International Speedway.

As the sanctioning body prepares to implement EFI for the full 2012 Sprint Cup Series schedule, NASCAR continues the process of gathering information on the new system.

Teams took part in a test on Monday at Martinsville Speedway and will now have an opportunity at Daytona the Tuesday prior to the season-ending Ford Championship weekend at Homestead-Miami Speedway.

NASCAR has so far been pleased with the progress made in testing the new system.

“I think most of the hurdles have been crossed with software and issues they had early on,” said NASCAR vice president of competition Robin Pemberton after the Talladega test ten days ago. “It looked to me like the cars were responding to changes. We didn’t have any issues on the track. It looked like a regular day at the race track for the most part.”
Sprint Cup teams will return to Daytona in January for the annual pre-season testing session prior to beginning the 2012 season with Speedweeks in February.

Martinsville fuel injection test goes well

Posted by Pete Pistone

From News Release

For the third time this month, NASCAR Sprint Cup Series teams tested Electronic Fuel Injection on track, as 10 cars churned out laps around Martinsville Speedway Monday. Teams from Roush Fenway Racing, Penske Racing, Michael Waltrip Racing, Hendrick Motorsports, NEMCO Motorsports, Joe Gibbs Racing, Furniture Row Racing, Earnhardt-Ganassi Racing and two teams from Stewart-Hass Racing participated in Monday’s session.

This marked the third EFI test for the NASCAR Sprint Cup Series this month. Previously, teams had tested at Charlotte Motor Speedway and Talladega Superspeedway. Plans call for the full implementation of EFI in the NASCAR Sprint Cup Series beginning with the 2012 season.

Tony Stewart, driver of the No. 14 Office Depot/Mobil 1 Chevrolet, and winner of Sunday’s TUMS Fast Relief 500 at Martinsville, said today’s test was all about helping his race team get better.

“This test is big for the engine guys and also for our overall organization,” said Stewart, who is second in points in the Chase for the NASCAR Sprint Cup. “It gives them the opportunity to read the fuel maps and get a feel for the ins and outs of the EFI system. We’re confident that this system will be bullet proof when we go all in with it next season. Being out here today, running laps; you do this to make your race team better.”

Stewart’s crew chief, Darian Grubb, said that his team came out of Monday’s test “very satisfied.”

“We’ve received a lot of data from the earlier tests and this was a good indicator on how the system might perform on a short track and we came away very satisfied,” said Grubb. “We’re all still in a bit of a learning process with the EFI and still doing some trouble shooting, but this is an exciting move we’re making in the sport.”

Grubb went on to say that Stewart provides the team with “excellent feedback” on how the car is handling on the track.

“Tony has experience racing with the EFI systems in the past and with his background in IndyCar and sprint cars, he is able to provide us with a lot of valuable and insightful feedback.”

AJ Allmendinger, driver of the No. 43 Best Buy Ford, drove a car for Roush Fenway Racing at the test and said that today was his first experience behind the wheel of an EFI stock car.

“It was kind of cool making laps in the EFI car after going 500 laps yesterday at this track,” said Allmendinger, who finished 11th in Sunday’s race. “It was pretty amazing seeing the marks on the walls and divots in the track from the race. We were able to make a few minor adjustments with our car today and all in all, it was a productive test for us.”

John Darby, NASCAR Sprint Cup Series director, said today’s test “was just one more step in the planning process for EFI.”

“Since the time we first began testing EFI in July in Kentucky, I think the teams have been able to work through just about all the configurations of race tracks and the different extremes of weather that they will see in 2012,” said Darby. “At Kentucky it was brutally hot and the teams were faced with the extreme heat and this morning it was 30 degrees here at Martinsville, so they’ve been able to test this system under a variety of conditions.”

Darby said that the feedback he has received from the drivers has been “consistently positive.”

“When they have the throttle wide open, they (the drivers) say the car might run even a little smoother,” said Darby. “When they run it mid-throttle, they say it might feel even a little softer in handling. They all say the cars are handling very similar to what they are used to driving now."

NASCAR concludes Charlotte fuel injection test

Posted by Pete Pistone

From News Release

DAYTONA BEACH, Fla.  — Teams representing 11 NASCAR Sprint Cup Series cars turned upwards of 400 miles Monday during a test of Electronic Fuel Injection (EFI) at Charlotte Motor Speedway. Both NASCAR officials and drivers were optimistic about the continued development of the system. Plans call for the full implementation of EFI in the NASCAR Sprint Cup Series beginning with the 2012 season.

“The entire NASCAR community has worked very closely together in developing the EFI system,” said Robin Pemberton, NASCAR vice president for competition. “Today was a positive step in the right direction for us. We have associated ourselves with some world-class technology partners, including McLaren, Freescale and Holley, and going to EFI next season is only going to enhance the racing. The horsepower should be about the same, or perhaps slightly more, the cars will be more fuel efficient, and it’s the right thing to do from an environmental standpoint. Plus, it helps us become more relevant with the production cars that our fans drive every day.”

Four Hendrick Motorsports teams, two Stewart-Haas Racing teams, one team from Richard Childress Racing, one team from Michael Waltrip Racing, one Earnhardt-Ganassi team, a team from Joe Gibbs Racing and one team from Roush-Fenway Racing participated in Monday’s test session.

The No. 6 Roush Fenway Ford, driven by Trevor Bayne, turned in the day’s fastest lap with a speed of 189.793 mph. Ricky Stenhouse Jr. also tested the No. 6 Ford on Monday.

Richard Childress Racing’s Jeff Burton said that Monday’s test provided some “great feedback for the team engineers to build upon.”

“To have the engine tuners interface with the drivers and teams at today’s test is very important in the development of this system,” said Burton. “The test is an excellent tool for the engineers to improve upon their ability to tune the engines.” 

Another NASCAR EFI test is scheduled for Thursday, Oct. 20 at Talladega Superspeedway. The test is set to run from 10 a.m. – 4 p.m. (CT).

NASCAR partners for fuel injection

Posted By Pete Pistone

DAYTONA BEACH, Fla. - NASCAR took another step toward introducing fuel injection to the sport on Friday when the sanctioning body introduced McLaren Electronic Systems and Freescale Semiconductors as partner companies to assist with the process.

NASCAR and its two new partners made the announcement Friday at the Daytona International Speedway media center.

The change from engines with carburetors to fuel injection will take place in 2012 with testing and development of engine packages taking place during this season.

NASCAR vice president of competition Robin Pemberton promised the move to fuel injection would not take place before 2012 and Friday's announcement finalized the timetable for the new engine configuration.

The engine development will only be for the Sprint Cup Series while the Nationwide Series and Camping World Truck Series will remain utilizing carburetors.

One issue that has always been a roadblock to NASCAR changing from carburetors to fuel injection system engines has been the ability for the sanctioning body to police things and keep teams from massaging the rules outside their guidelines.

But Pemberton is confident the system NASCAR will introduce in 2012 will not encourage cheating.

"We are confident with McLaren and with Freescale these systems will be bulletproof, will be cheat proof," said Pemberton.

Pemberton also said restrictor plates will still be used at Daytona and Talladega but will fit on the throttle body when the switch to fuel injection is made.

While McLaren has a long history of Formula One competition this is the company's first foray into NASCAR and the fuel injection system produced for the Sprint Cup Series will be exclusive and specific to stock car racing.

From Team Release
DAYTONA BEACH, Fla. (Feb. 11, 2011) – The National Association for Stock Car Auto Racing (NASCAR) announced today a historic technology partnership with Freescale Semiconductor and McLaren Electronic Systems to develop and integrate fuel injection systems into the NASCAR Sprint Cup Series, targeted for the 2012 season.

Freescale will provide the processors for McLaren’s engine control units (ECUs) that will be used to manage the fuel and ignition systems in the engines for all NASCAR Sprint Cup Series cars, replacing carburetors which have been used in the series since its inception in 1949. NASCAR and its top series teams will test the technology during the 2011 season with the anticipation of the systems being rolled out for the 2012 NASCAR Sprint Cup season.

The fuel injection system will bring increased technology and efficiency to the NASCAR Sprint Cup cars while at the same time complementing the car’s high performance. This announcement marks the most significant strategic change to NASCAR’s engine platform in decades. As part of this program, Freescale is designated as the “Official Automotive Semiconductor of NASCAR” and McLaren the “Official Engine Control Unit of NASCAR.”

“This move gives us an additional opportunity to incorporate the best technology in our race cars that will enhance the sport in a variety of ways,” said Robin Pemberton, NASCAR vice president of competition. “Selecting these two industry leaders reflects our commitment to this new technology which our manufacturers and teams have embraced. This is a positive step that will provide greater fuel efficiency and a greener footprint while maintaining the same great competition we have seen on the race track.”

For decades, most of the parts and equipment on NASCAR race cars have been highly customized for racing but at the same time relevant in standard automobiles. This move to fuel injection brings back an important synergy between these two vehicle types.

ECUs maximize each racing team’s ability to get the most performance and best fuel economy under all race conditions. With this announcement, plans call for every NASCAR Sprint Cup Series race team to use a control system with Freescale’s advanced 32-bit Power Architecture <sup style="outline-width: 0px; outline-style: initial; outline-color: initial; font-weight: inherit; font-style: inherit; padding: 0px; margin: 0px; border: 0px initial initial;">® </sup>  based engine management processors at its core, beginning in 2012. These same processors power millions of today’s most energy efficient engines.

The ECUs are tamper-proof, ensuring that only approved software may ever be run during a race weekend. Additionally, NASCAR will have special electronic tools at its disposal during every event to ensure the legality of all ECUs.

 “Freescale’s partnership with NASCAR and McLaren goes beyond a simple business relationship,” said Henri Richard, senior vice president and chief sales and marketing officer at Freescale Semiconductor. “It reflects our shared values in the automotive industry and our common dedication to technology improvement, high performance, energy efficiency and leadership in safety. It also continues to demonstrate the success of the Power Architecture as the leading microcontroller architecture in the automotive segment. NASCAR trusts us to provide cutting-edge automotive solutions for the next generation of engine management. Our products and technology will power every NASCAR Sprint Cup Series race car next year and we are honored to be the sole automotive semiconductor provider for America’s largest motorsport.”

Since 1966, McLaren has a legacy of racing success in the United States, totaling 43 victories during its tenure in the Can-Am Challenge, 10 wins at the U.S. Grand Prix and three wins at the illustrious Indianapolis 500. In addition, McLaren Electronics Systems has been a supplier to NASCAR teams since 2005 and also provides the ECUs that will be available late summer 2011 in the McLaren MP4-12C high-performance sports car. Freescale technology has been at the heart of McLaren’s engine control and data systems racing technology since 2000 and it provides the power behind all of McLaren’s major racing programs. Freescale is the largest U.S. based producer of automotive electronics and its technology enables virtually all automotive innovation in use today, from advanced engine systems to navigation and active safety.

“We are excited to build on our existing relationships with NASCAR and Freescale for this critical technology,” said Peter van Manen, managing director, McLaren Electronic Systems Limited. “McLaren has been providing reliable, high performance electronics to professional motorsports and other high performance automotive applications in North America, Europe and Asia for more than 20 years and we are both proud and delighted to be bringing our ECU technology into NASCAR’s Sprint Cup Series.”
