Where's the action beyond F1, you ask? | This Week In Motorsports

All the action from Asians in global motorsport, this week.

We had a nearly 50% Asian grid in a European Championship (42% for the nerds), last lap drama that saw a team lose the lead of the 3-hour Fuji SUPERGT, some crushingly dominant performances in sportscar racing, and some tough luck for karters. We’ve got you all covered

The F4 Southeast Asian Championship certified by the FIA, returned back in 2025 with its season opener at the Sepang International Circuit. Across a weekend marked by rapidly shifting weather - moving from dry to wet and everything in between - one driver stood unfazed: Vietnam’s Alex Sawer who dominated all three races to kick off the season with a perfect record.

Behind him, the battle for podiums was fierce. Seth Gilmore and Inigo Anton impressed in Race 1, while Rishon Rajeev added his name to the spotlight with two P3 finishes in Races 2 and 3.

The 2025 Japanese F4 Championship began over Golden Week alongside the SUPER GT round at Fuji Speedway. A 30-car grid delivered three closely contested races across the weekend. Tokiya Suzuki claimed the opening race and followed it up with consistent drives to finish third in both Race 2 and Race 3.

Race 2 saw Ryo Shirasaki convert his pole position from Race 1 into a win, finishing ahead of Itsuki Sato. In the final race, Sato responded with a win of his own, narrowly keeping Tosei Moriyama behind by 0.4 seconds. A steady start to the season, with a mix of familiar and emerging names on the podium.

At Round 2 of the Spanish F4 Championship in Navarra, Vivek Kanthan continued to show promise. After qualifying P4, a 7-place penalty from Round 1 saw him start Race 1 from P11, eventually finishing P14. He followed that up with a solid drive to P7 in Race 2 and rounded off the weekend with a P8 in Race 3 - bringing home points across two races. He now holds P10 in the overall standings and sits third among rookies.

For fellow rookie Kyuho Lee, the weekend began on a slower note. Starting from P28 in Race 1, he climbed to P25 and P23 in the next. But it was Race 3 where he made the biggest leap - starting P24 and finishing P10, earning his first championship point of the season after a strong recovery.

Round 2 of the FIA European Karting Championship in Portimão saw a tough weekend for many of Asia’s rising karting stars across both the OK and OK-Junior categories, with a mix of standout efforts and unlucky setbacks.

In the OK-Junior class, Arata Endo of Japan was the clear standout. After an excellent 3rd place in Qualifying from Group A and a solid P4 finish in Super Heat A—despite a time penalty—Endo entered the final as a serious contender. Unfortunately, a DNF in the final denied him what could’ve been a career-best result, though he still ranked an impressive 4th overall in the classification.

Fellow junior drivers Oliveri Sini (Indonesia) and Houzai Jiang (China) had more challenging outings. Sini failed to finish the Super Heat and missed final qualification, ending 61st overall. Jiang placed 26th in his Super Heat and also missed the cut for the final, settling for 55th in classification.

In the OK category, both Qarrar Firhand (Indonesia) and Sara Matsui (Japan) struggled to find pace in a competitive field. Firhand ended 61st in qualifying and could only manage 21st in Super Heat A, missing out on the final with a 58th-place overall finish. Matsui, similarly, finished 26th in her Super Heat, and closed the weekend in 65th.
