The opening round of the 2026 GT World Challenge (GTWC) America powered by AWS has suffered an early setback, with the No. 88 Kellymoss Porsche 911 GT3 R Evo withdrawn following a testing crash at Sonoma Raceway.
As reported by Sportscar365, the incident occurred during Wednesday’s final test session, when John Gilliland lost control in Turn 7. The Pro-Am class entry sustained significant chassis damage in the crash, ultimately forcing the team to withdraw the car from the weekend’s action.
Importantly, Gilliland—an FIA Bronze-rated driver—escaped the incident without injury, providing some relief despite the circumstances.
Decision made despite available resources
Following the accident, team management assessed the situation before deciding not to continue with the No. 88 entry. This decision came even though Kellymoss had two spare Porsche 911 GT3 R Evo chassis available on-site.
Bill Riley, who oversees the team’s GT World Challenge America programme, confirmed the withdrawal, signalling a cautious approach ahead of the season opener.
As a result, Kellymoss will now concentrate its efforts on its two remaining Pro-Am entries. The No. 017 car, driven by Colin Braun and Michael Clarke, and the No. 13 entry of Riley Dickinson and Todd Parriott will carry the team’s hopes for the weekend.
Both line-ups offer competitive potential, allowing Kellymoss to remain a factor despite the early setback.
Grid reduced ahead of 2026 GTWC America Sonoma race weekend after No. 88 Kellymoss withdrawn
Consequently, the withdrawal reduces the GT World Challenge America grid to 18 cars for the Sonoma round. Additionally, the No. 50 Chouest Povoledo Racing Chevrolet Corvette Z06 GT3.R will only participate in practice sessions, serving as extra track time for Ross Chouest’s GT America powered by AWS programme.
