With the Summer Olympics hitting full stride this week, there will be no shortage of worldwide athletic talent on the ultimate international stage.

Comparatively speaking, NASCAR remains a closed shop. NASCAR's big-league Cup Series is in its 77th season this year, and so far just six racers born outside of the United States have visited Victory Lane.

Those six have won nine races overall, but look for that victory number to increase because two of those racers are still active and competitive.

Mario Andretti

GREAT AMERICAN BOOK Celebrate a fast-paced history of the Daytona 500 with new book; foreword by Richard Petty

Birthplace: Istria, Kingdom of Italy (present-day Croatia).

NASCAR win: 1967 Daytona 500

Did you know: You want diversity from your legendary racers? Mario won championships in IndyCar and Formula One, while also winning crown jewels like the Indy 500, 12 Hours of Sebring, 24 Hours of Daytona and, in 1967, the Daytona 500. He led 112 of the 200 laps and was one of just two cars on the lead lap at the end — Holman-Moody teammate Fred Lorenzen was the other. Mario started 14 NASCAR races between 1966-69 before concentrating solely on his open-wheel career, which turned out OK, by the way.

Earl Ross

Birthplace: Prince Edward Island, Canada.

NASCAR win: 1974 Old Dominion 500 at Martinsville.

Did you know: Now you see him, now you don’t. After making his first three NASCAR starts in 1973, Ross started 21 races in ’74 (15 of the for owner Junior Johnson), got his win and 10 other top-10s and was named Rookie of the Year. He started just one race in each of the next two years and then was gone. He continued short-track racing into the 1990s. In his lone win, he was the only car to complete all 500 laps. Buddy Baker finished one lap down in second.

Juan Pablo Montoya

Birthplace: Bogota, Colombia

NASCAR wins (2): 2007 at Sonoma, 2010 at Watkins Glen

Did you know: Both of Montoya’s Cup Series wins came on road courses and you might think that would be his “happy place” during his stock-car career, but 20 of his 24 top-five finishes came on ovals. He was as close as they come to a modern Mario Andretti, winning races in Formula One, IndyCar (including the Indy 500) and sports-car racing (including three Rolex 24s).

Marcose Ambrose

Birthplace: Tasmania, Australia.

NASCAR wins (2): 2011 and 2012 at Watkins Glen.

Did you know: He also won five times in NASCAR’s Xfinity Series. Six of his seven overall NASCAR wins came at Watkins Glen. Ambrose was a two-time Aussie SuperCars champ (2003-04) before coming to NASCAR full-time in 2007. He returned to SuperCars after the 2014 NASCAR season, but ran just 10 races over the next two seasons before retiring at age 39.

Daniel Suarez

Birthplace: Monterrey, Mexico.

NASCAR wins (2): 2022 at Sonoma, 2024 at Atlanta.

Did you know: Suarez remains a work in progress as he approaches the 2024 Cup Series playoffs in his fourth season with Trackhouse Racing. Won the Xfinity Series championship (and three races) in 2016 and was likely ticketed for one more season in that series, but was quickly promoted to Joe Gibbs’ Cup team in 2017 when Carl Edwards abruptly retired. He’s a product of NASCAR’s Mexico Series, where he won 11 times in 76 starts.

Shane van Gisbergen

Birthplace: Auckland, New Zealand.

NASCAR win: 2023 at Chicago.

Did you know:  Like Suarez, SVG is still very active and has qualified for the Xfinity Series playoffs with three wins already this season — all three on road courses, which continue to be his specialty though he’s improving on ovals. He took the Marcos Ambrose path to NASCAR, via the Aussie SuperCars, where he won three championships (2016, ’21 and ’22) and a staggering 63 races between 2011-22.
