CONCORD, N.C. – There are many unknowns about the Charlotte Motor Speedway road course – passing zones, tire compound, even race distance – but Martin Truex Jr. said Wednesday there is one certainty.
When the new layout makes its debut as the Round of 16 cutoff race next season, playoff drivers will want to be assured of advancing ahead of time.
“I’m going to be hoping I’m going to win one of the first two in that round,” Truex said. “I’m going to put this right in there with Talladega.”
The Furniture Row Racing driver tested tires Tuesday and Wednesday on the 18-turn, 2.42-mile track (which incorporates most of Charlotte’s 1.5-mile oval) with Kurt Busch, Jamie McMurray and Daniel Hemric.
Busch said the layout was similar to the Daytona International Speedway road course but with a much smaller footprint that ratcheted up the intensity.
“There’s no room for taking a break or having a quick, deep breath down the straightaway,” Busch said. “As soon as you’re in high gear off turn 2, you’re in a chicane. Back through the gears, you’re downshifting on the brakes to go to the frontstretch chicane. It’s a very busy track.”
There is a 35-foot change in elevation on the course, which features two chicanes that track officials say are designed to encourage passing and provide an option for rain tires.
The transitions between the high-banked surface and the flatter road course make it tricky to navigate.
“There’s all kinds of craziness going on,” Truex said. “Turns 1 and 2 are pretty wild, narrow with concrete walls on both sides. Intimidating.
“It’s a unique track. I don’t know if I’ve run a road course anything like it because of the elevation changes, the bumps and the humps. Charlotte isn’t smooth to begin with and add in infield that has been around a long time, there’s a lot of swells in it. It definitely is interesting. It’s a unique challenge. I don’t know I’ve raced anything like it.”
The track announced the race distance as 500 kilometers, which would make it the longest road course race on the circuit, but NASCAR didn’t confirm the length of the first playoff race with right turns (saying “it provided valuable data that will be part of the equation in determining the distance for next fall’s race”).
Also in flux is the layout. Truex talked to Speedway Motorsports Inc. CEO Marcus Smith about adding some safety features such as curbing, runoff areas, tire barriers and walls.
Busch also has recommended eliminating Turn 8 to connect the seventh and ninth turn, reducing the number of slow corners on the track. “There are a lot of slow sections with turns 5, 6 and 7,” Busch said. “Those are good rhythmic corners. … (But) a 3,500-pound car going 35 mph too many times isn’t too exciting. We need to speed up the track a bit.”
Truex, who shaved 10 seconds off his lap time on the first day, estimated the top-end speed is about 175 mph and said the ninth turn (before entering the oval in Turn 1) is the slowest.
Where are the best passing zones?
“That’s a great question,” he said. “I can’t tell you that. Single-car runs so far, it’s hard to say. There’s a lot of places you can crash. I’m not sure about the passing yet.”
After starting on the Watkins Glen tire, it’s expected Goodyear could bring a softer tire next year for faster speeds and better grip. Lap times were in the 90-second range, which Busch said was slower than anticipated but illustrated the difficulty of balancing a tire between a high-speed oval and a road course that drove more like the technical Sonoma than the high-speed Watkins Glen.
“The corners are sharp, low grip and we have 800 horsepower, so we’re trying to put the power down and sliding the tires quite a bit,” Busch said. “The process is to work with Goodyear and Charlotte Motor Speedway to find things we can change safety-wise and recommend the shapes of chicane around the back straightaway and even the front straightaway section.”
Busch, who drove the No. 14 Ford in place of Stewart-Haas Racing teammate Clint Bowyer, said he volunteered for the race because of its playoff implications in 2018.
“It’s a cutoff race,” he said. “Teams better get their arms wrapped around it and their heads focused on it because it’s one of the most important races of the year. When it’s a new situation like this, there’s a lot of oddities and variables. Fans will see it.”
