A mechanical issue on takeoff forced his team charter to abort the initial journey to Mexico City. He arrived at the venue Friday, a day late, and after winning the pole Saturday, the New Zealander fell seriously ill.

He was sleeping on the floor of his hauler before Sunday’s race, unsure he’d be able to physically complete the 100-lap event at Autódromo Hermanos Rodríguez.

But there’s something special about the Kiwi and new venues, especially in the rain, and he salvaged the weekend by winning on the road course to earn an automatic berth into NASCAR’s playoffs.

Van Gisbergen led 60 of 100 laps and beat Christopher Bell by 16.567 seconds.

“I tried to treat it like when I go to Asia, just drink bottled water and be careful in the shower and brush your teeth with bottled water, but I just went downhill,” Van Gisbergen said. “Couldn’t keep anything in. Everything just went straight through me. I felt really queasy and my mind was there, but my body just had so much pressure in my stomach. Crazy weekend and everyone dug deep.”

It was the second Cup Series victory of his career. He won in his NASCAR debut at the inaugural 2023 street course race in Chicago — a victory that changed his career trajectory. Van Gisbergen left Australia V8 Supercars, where he was a multiple champion, for a full-time move to NASCAR.

Although he had success in the Xfinity Series — he won three races last year as Trackhouse Racing developed him for a Cup Series ride — Van Gisbergen has struggled this year at NASCAR’s top level.

He started the race ranked 33rd in the Cup standings with only one top-10 finish through the first 15 races of the season. But his victory in Mexico City revived his season and gives him a shot to race for the Cup Series championship.

“It means everything to us, this is why I’m here,” Van Gisbergen said. “I am getting better and more competitive. We’re really making a lot of progress.”

Van Gisbergen celebrated in his traditional rugby-style way — he drop-kicked a signed football into the grandstands and then said he had recovered enough to enjoy “some Red Bulls mixed with adult beverages” later Sunday.

Van Gisbergen benefitted from an early pop-up rain shower on the first lap of the race because he’s an exceptionally skilled driver on a wet surface. His win at Chicago was in monsoon-like conditions.

Trackhouse now has two of its drivers — Ross Chastain and Van Gisbergen — locked into the playoffs. But it was a bit of a disappointment for Daniel Suarez, the Monterrey native who thrilled the hometown crowd with a win in the Xfinity Series race on Saturday, as he failed to challenge his teammate for the win and finished 19th.

“I wish I was in the mix fighting for it a little more, but it just wasn’t in the cards,” Suarez said. “Every single thing about this weekend exceeded my expectations, the people, the fans, the sponsors, the excitement, the energy.”
