Early life and education
Mason Filippi was born on April 23, 1998. He grew up in Alamo, California and attended high school at Berean Christian High School in nearby Walnut Creek. He studied at Diablo Valley College and Arizona State University.
Filippi was gifted his first dirt bike at the age of four, his first go-kart at the age of eleven, and his first Mazda Miata at the age of fourteen. He earned his provisional license at the age of fifteen after attending the Sports Car Club of America (SCCA) driver's school.
Career After receiving his full competition license from the SCCA, Filippi began entering races in the San Francisco region (SFR) and was named the 2014 SCCA SFR Rookie of the Year. In 2015, he won the National Auto Sport Association's Teen Mazda Challenge West Coast title. His victory in that Spec Miata series led to his appearance as one of nine finalists in the 2015 Mazda Road to 24 Shootout. Later in 2015, Filippi was on the Grip Racing team that won the 25 Hours of Thunderhill race in the E1 class. In 2016, he and his team repeated as winners of that race in the E1 class.
Global MX-5 Cup Filippi joined the Winding Road team for the 2016 season of the Global MX-5 Cup. He drove the No. 2 car in the Spec Miata series, competing in six out of the twelve races and finishing in 34th place in the standings with 125 overall points. His best finish in a race was fourteenth place, which he achieved at both the WeatherTech Raceway Laguna Seca and Watkins Glen International.
Pirelli World Challenge/TC America Series Filippi first entered the Pirelli World Challenge in 2016, racing in the final four events of the season in the TCA class for Atlanta Motorsports Group. He finished in the top ten in each of his races with his highest finish (fifth) coming at Laguna Seca. He placed fourteenth in the overall standings with 296 points for the 2016 season.
For the 2017 Pirelli World Challenge, Filippi joined Winding Road Team TFB and began competing in the TC class. He drove the number 12 BMW M235iR. That year, he competed in all twelve races, earning his first Pirelli World Challenge victory at Canadian Tire Motorsport Park in round four. He also achieved the fastest lap in that race. Including that event, Filippi finished in the top ten in nine races that season. He finished fifth in the overall standings with 173 points.
Filippi remained with Team TFB for the 2018 Pirelli World Challenge, and he also joined the TCR class racing in the No. 12 Volkswagen Golf GTi TCR. In August 2018, however, Filippi announced that he would be joining RealTime Racing for the final four races of the season, opting to drive the No. 44 Honda Civic Type R TCR. He had his best finishes of the season in that car, coming in third and second respectively at the final two races of the season at Watkins Glen. He finished fourth in the overall standings with 183 points.
For the 2019 season, the Pirelli World Challenge was rebranded as the TC America Series. Filippi returned to Team TFB at the beginning of the season, driving the number 12 Hyundai Veloster N TCR in the TCR class. At the season's first two races at the Circuit of the Americas in Austin, Texas, Filippi came in first, achieving the initial race's fastest lap, as well. Because of scheduling conflicts with the Michelin Pilot Challenge season, Filippi did not compete in the next four races on the TC America Series schedule. In May 2019, it was announced that he would return to the TC America Series as a member of the Copeland Motorsports team. He continued driving the Hyundai Veloster N TCR and went on to win four additional races that season. With 187 points, he finished third in the overall standings despite competing in only ten of the sixteen races that year.
IMSA Michelin Pilot Challenge In January 2019, it was announced that Filippi would join Bryan Herta Autosport (with Curb-Agajanian) to compete in the TCR class of the 2019 Michelin Pilot Challenge in the No. 21 Hyundai Veloster N TCR with co-driver Harry Gottsacker. Both Filippi and Gottsacker were rookies on the series. The duo appeared in the top ten in each of the ten races that season and finished on the podium in three races, including first place at Road America in Elkhart Lake, Wisconsin. That victory came after the No. 89 car, which finished ahead of Filippi, was disqualified for failing to give one of its drivers the minimum drive-time. Filippi and Gottsacker finished in second place in the overall standings with 268 points.
For the 2020 Michelin Pilot Challenge season, it was announced that Filippi would stay with Bryan Herta Autosport (with Curb-Agajanian) but would become Michael Lewis' co-driver in the No. 98 Hyundai Veloster N TCR. The pair came in fourth in the season's first race at the Daytona International Speedway. The next race in the series was scheduled for March 2020, but was postponed due to the COVID-19 pandemic. In the meantime, Filippi competed in the IMSA iRacing Pro Series before the Michelin Pilot Challenge returned in July 2020. Filippi and Lewis secured two victories in the 2020 season, one at Virginia International Raceway and the other at Road Atlanta. They finished in third place overall with 273 points.
For the 2021 Michelin Pilot Challenge season, Filippi was part of the Hyundai USA/ Bryan Herta Autosport Team Driver to drive for Copeland Motorsports in the TCR class. He would drive the No. 51 Hyundai Veloster N TCR with co-driver AJ Muss.
IMSA WeatherTech SportsCar Championship In January 2026, DXDT Racing announced that Filippi would be joining the team's driver lineup for the entirety of the 2026 season. Filippi's co-drivers for the endurance races were Salih Yoluç, Charlie Eastwood, with IndyCar ace Scott McLaughlin joining the lineup for the season opening Rolex 24 Hours of Daytona. Filippi would be joined by former Bryan Herta Autosport teammate Robert Wickens for the sprint races.
NASCAR On May 25, 2022, DGM Racing announced that Filippi would make his Xfinity Series and NASCAR debut in the race at Portland in the team's No. 91 car. He was also scheduled to make his NASCAR Camping World Truck Series debut at Sonoma with G2G Racing however due to him not being able to learn the truck quick enough, he was switched out with Stefan Parsons. He would later make his debut at Mid-Ohio.
