NASCAR says it’s “unacceptable” for Next Gen cars to catch fire

On Lap 276 of 367 in Sunday night’s Southern 500 at Darlington (S.C.) Raceway, fire erupted first out of the right side of Harvick’s No. 4 Ford and then the left, which forced him to bring the car to a stop at the bottom of Turn 1.

Harvick safely exited the vehicle which quickly became engulfed by smoke and fire. Harvick had not experienced any issues with his engine prior nor suffered any damage to the car prior to the incident.

In an interview afterwards, Harvick blamed the issue on “crappy parts” on the Next Gen car and in reference to action taken by NASCAR to address the problem said, “They don’t care.”

In an interview Tuesday with SiriusXM NASCAR Radio, Scott Miller, NASCAR’s senior vice president of competition, disputed Harvick’s assertion.

“Nobody wants to see this happening. I know that was an emotional time and his race was ruined but to say that NASCAR didn’t care is about as far from the truth as you could get,” Miller said. “That’s really all I have to say about that.

“I’m not going to get into any kind of back-and-forth contest with Kevin over the airwaves. I think he actually does know we do care.”

Looking into it

Miller pointed out NASCAR has been working on the issue since it first came to light at the Indy Road Course, when the cars of Chris Buescher and Joey Logano both had fires erupt in the rocker box from crash damage, mostly from under the right side of the cars.

“We’re certainly digging into the cause. We had cars in this morning looking for signs of anything that may have triggered that. We have done so all year,” Miller said. “There’s a lot of rubber at Darlington, you know the cheese grater that we’ve all talked about.

“We’re not certain if rubber getting into the rocker box was the problem (in Harvick’s case) or not. We’re debriefing it all. It’s unacceptable for the cars to catch on fire.”

Following the fires suffered by Buescher, Logano and others by Chase Briscoe and Alex Bowman, NASCAR mandated an exhaust shroud be added to the car, which appeared to help address the problem.

Harvick’s issue seemed unique in that his car had not been damaged and fire had come out of both sides of the car simultaneously.

“We’ve been working on different solutions for different things along the way that seem to maybe are the trigger. And, you know, obviously we still have work to do,” Miller said.

“We’re looking at clearances on…
