NASCAR issued a bulletin to Sprint Cup, Xfinity and Camping World Truck teams with changes to the rule book Wednesday.
Among the changes is a rule the requires a driver, crew chief and spotter to have radio communication, a new single rear-end differential assembly rule and a single transmission rule.
Previously, teams could change as many gears as they wanted but they had to be the right ratio. Now, a single rear end differential assembly rule will be enforced at all events except at Martinsville Speedway, road course events, the Daytona 500, the Sprint Showdown and the NASCAR Sprint All-Star race.
Martinsville and road courses are hard on gears. Because of the number of events leading up to the Daytona 500, teams can make a change. It’s also easy to break a gear in All-Star qualifying.
This rule should eliminate qualifying gears.
NASCAR stated that failure to comply with this rule could result in loss of practice time, loss of opportunity to qualify and confiscation of the rear end differential assembly, along with any other actions the series director deems necessary.
NASCAR formalized that a driver, crew chief and spotter must be able to communicate on the radio during an event.
NASCAR stated that effective Jan. 1, 2016 teams will be permitted only one transmission change after qualifying and before the race for events at Pocono Raceway and road course events.
Other changes included adding the new qualifying format for super speedways previously announced and other technical updates.
NASCAR announced Tuesday it has fined seven crew chiefs for lug nut violations from the Cup and Xfinity races this past weekend at Las Vegas Motor Speedway,
In the Cup Series, NASCAR issued fines to crew chiefs Matt McCall (Kurt Busch), Greg Erwin (Matt DiBenedetto) and Seth Barbour (John Hunter Nemechek) for having one lug nut not safe and secure on their cars. Each crew chief was fined $10,000.
Chad Knaus, whose success as a crew chief is nearly unparalleled in NASCAR, will step down from that role after this season and move into a leadership position at Hendrick Motorsports, the team announced Tuesday.
Knaus will become vice president of competition. He will oversee technical development for Hendrick Motorsports, including implantation of the Next Gen car in 2022. He also will be responsible for personnel for each of the four teams, including crew chiefs, pit crews, engineering, fabrication, assembly and other team-related staff.
Knaus won seven championships as Jimmie Johnson’s crew chief. Only Hall of Fame crew chief Dale Inman won more titles. Inman won eight, scoring seven with Richard Petty and one with Terry Labonte. Knaus has 82 career Cup wins. All but one came with Johnson. William Byron scored his first career Cup win in August at Daytona with Knaus as his crew chief. Byron was eliminated from the playoffs last weekend. The 49-year-old Knaus is the only crew chief to have competed in NASCAR’s postseason all 17 years.
“When I started at Hendrick Motorsports (in 1993) working for Ray Evernham, my goal was to be a crew chief,” Knaus said in a statement from the team. “Starting at a young age, I wanted to win every race we entered and battle for every championship.
“Mr. (Rick) Hendrick has given me the chance to do exactly that, and I could not be more thankful to him. After all these years, my competitive desire has not changed at all, but now I have a family that deserves my attention. This new executive role will allow me to compete in a different way with all four of our teams while spending more time with my wife and two young children.
“I appreciate the company supporting my decision, and I’m truly excited about the challenge ahead of me to help us grow and win. I’m also looking forward to working closely with Jeff (Andrews), who I admire and have great respect for. I owe so much to Mr. Hendrick and everyone at Hendrick Motorsports, and I’m ready for the next chapter.”
A new crew chief for Byron will be announced at a later date.
“In life, it’s rare to witness true excellence first-hand, but that’s precisely what we’ve been treated to with Chad,” Hendrick said in a statement. “Today’s announcement is bittersweet because, in my opinion, he is the finest crew chief our sport has ever seen.
“Although we’re going to miss him atop the pit box, I’m heartened that Chad has made this decision for himself and his growing family and that he is energized about the opportunity to move us forward in a new capacity. There is no one with higher standards or a stronger passion for winning. He will continue to elevate Hendrick Motorsports and instill his championship mentality throughout the company.”
Knaus served two races as crew chief for Casey Atwood in 2000 and then did one race for Stacy Compton that season. In 2001, Knaus was paired with Compton. Knaus rejoined Hendrick Motorsports to be Johnson’s crew chief in 2002. They remained together until 2019 when Knaus moved to Byron’s team.
Knaus will report to Andrews, 55, who has been promoted to executive vice president and general manager, effective immediately.
Andrews joined Hendrick Motorsports in 1992 and most recently served as vice president of competition. He had held that role since 2017.
Previously, Andrews held a leadership position in the team’s engine department, including director of engine operations. In his expanded role, Andrews will oversee all competition-related departments, including powertrain, manufacturing and racing operations. He will continue to support the organization’s technical relationship with Chevrolet and remain its primary liaison with NASCAR’s competition group. Andrews reports to Hendrick Motorsports president Marshall Carlson.
“In my almost 29-year NASCAR career, I’ve been fortunate to work for just one organization,” Andrews said in a statement from the team. “Mr. Hendrick is a racer and a fierce competitor. His drive to win is contagious, and I’m grateful to have a team of like-minded people who share that passion. Racing is all I have ever done professionally. When I left my home and my family 33 years ago to pursue this dream, I never could have imagined the opportunities that have been provided by so many people, most importantly Mr. Hendrick.”
Said Hendrick in a statement: “As we look to the years ahead, Jeff and Chad are going to play significant roles in our success. They’re tremendous leaders who are respected within our organization and across the entire auto racing world. In addition, they each bring unique strengths and skillsets that will complement each other extremely well and benefit all of Hendrick Motorsports. We’re in the business of winning, and this combination is going to help us do just that.”
