Martin Truex Jr.: VHT ‘a huge factor’ in Coca-Cola 600 — but wouldn’t work as well elsewhere

Leave a comment

CONCORD, N.C. — Though the rain paid a visit to the Coca-Cola 600, the traction agent applied high in the corners of Charlotte Motor Speedway was a “huge factor” in NASCAR’s longest race, according to Martin Truex Jr.

Truex, who led a race high 233 laps, lauded the VHT chemical used to improve racing at the 1.5-mile track after a dud of an All-Star Race.

“I think last weekend the middle groove, middle to high middle, was nonexistent,” Truex said after finishing third early Monday morning. “It was the slickest part of the racetrack.”

But that changed Sunday. Following Saturday’s Xfinity Series race, NASCAR and the track reapplied refresh coats of VHT to the upper grooves in the turns after consulting drivers and crew chiefs. Even after a downpour swept over the track on Lap 143, Truex said the traction compound was a factor for 375 of the race’s 400 laps.

“It was the main groove,” Truex said of the higher grooves. “Where typically there is the least grip (there) on this racetrack, it was the most tonight. It definitely played a factor. It changed the race quite a bit. I think the downforce rules this year changed it quite a bit as well. The bottom of the racetrack is so bumpy and so slick, I’m telling you after 10 laps it’s all you can do to make laps without crashing down there.

“It definitely changed the race tonight. It made it a lot of fun. I thought it was a good addition.”

Winner Austin Dillon thought the VHT – also known as PJ1 TrackBite – benefited the race. But the Richard Childress Racing drive would like to see a change in where the agent is applied to the track surface.

“The middle groove had a lot of speed, took away from the bottom,” Dillon said. That’s usually dominant here. The bottom got good again. After the rain, the bottom was pretty dominant. As the race went on, I could actually see the VHT leaving the track. It was getting clean higher and higher.

“We’ve got something there as far as trying it. It’s not a bad thing. I really think we should try it more often. I think the next thing you look into is the placement of it. I feel like we needed more on the very top because the middle was really dominant, but you couldn’t really get into the top of it like you needed to. That would be my next shot at it. It’s not a bad thing at all. I like it.”

What’s next?

The chemical has been used on the concrete high banks of Bristol Motor Speedway and the asphalt of Charlotte and been mostly praised.

Should it be tried at any other tracks on the NASCAR circuit?

“I don’t think so,” Truex said. “I think this track is so unique, the pavement here, the geometry of the racetrack, the bumps that are in it. It’s almost got a concrete feel the way the bumps are. They’re really, really small, high‑frequency bumps, almost like a washboard, kind of the feeling you get at Dover (International Speedway). Most asphalt tracks are not bumpy that way. They’re more of a swell. The car kind of goes through swells, a place like (Chicagoland Speedway) or Atlanta (Motor Speedway).

“It’s very, very different here. The pavement is different than anywhere we go. The bumps in the racetrack are way different than anywhere we go. I think both of those things kind of contribute to us needing to do some different things here to change-up the racing.”

Ricky Stenhouse Jr., Kyle Larson want Cup All-Star Race at Iowa Speedway

NASCAR has been sending its Xfinity and Camping World Truck Series to Iowa Speedway since 2009, but its premier series has never held a race at the .875-mile track in Newton, Iowa.

Ricky Stenhouse Jr. and Kyle Larson would like that to change sooner rather than later.

Stenhouse and Larson spoke to the Des Moines Register ahead of this weekend’s NASCAR races at the track.

The Roush Fenway Racing driver and former Iowa winner expressed enthusiasm at Iowa someday hosting the Monster Energy All-Star Race.

“To see how much support that the Iowa Speedway gets from the fans, it’s pretty incredible,” Stenhouse said. “I’d love to get the All-Star race here.”

The exhibition has been held at Charlotte Motor Speedway every year but one since it was introduced in 1985. It was at Atlanta Motor Speedway in 1986.

But with lackluster races and fan turnout in recent years for the event at the 1.5-mile track, support has been growing to possible hold the event at other tracks.

“I would like that better than Charlotte, for sure. … I’d be down for it,” Larson told the newspaper of having the event in Iowa.

Iowa Speedway opened in 2006 and was bought by NASCAR in 2013.
