G4 Racing has signed Leonid “Leo” Sapgir for the 2027 Spanish Winter Championship (SWC) and F4 Spanish Championship. The karting graduate will make his single-seater debut with the team, which has already begun preparing him through on-track testing and simulator sessions.
Sapgir steps up from international karting
Sapgir brings experience from international karting events, including the WSK Euro Series, WSK Final Cup and Italian ACI Karting Championship. Now, he will adapt to Formula 4 machinery as he prepares for his first competitive single-seater campaign.
The youngster welcomed the move to G4 Racing, highlighting his early progress with the team.
“I am really glad to be joining G4 Racing for my single-seater debut. So far, it has been a pleasure working with the team and getting my first laps in F4 with them. This is an important step in my career, and I can’t wait to see what we can achieve together in the upcoming season of SWC and the F4 Spanish Championship. A big thanks to everyone who supports me, Patrick Gnos, and the whole team. Looking forward to what’s ahead.”
G4 Racing prepares for two championship campaigns
G4 Racing already competes in the F4 Spanish Championship, providing Sapgir with an established team environment. Its current programme combines circuit testing and simulator sessions to help the newcomer build mileage and confidence ahead of 2027.
Team principal Patrick Gnos welcomed Sapgir’s early commitment and praised his initial test outings.
“Welcome to the team LEO! We are really happy to have Leo committing early to the Spanish Winter Championship and the F4 Spanish Championship 2027. Leo has already started to prepare next season and does well during the first test days. We are looking forward to working with Leo and climbing the road to success together. The feeling is good!”
The winter campaign will offer Sapgir race experience before the seven-round 2027 Spanish F4 season begins at Jarama in April. With the Barcelona finale set for October, he faces a busy first year in single-seaters.
