Austria's Red Bull Ring will remain on the Formula One calendar until at least 2030 after the sport announced a contract extension on Sunday.
The race in Spielberg is a home one for the energy drinks company that owns two of Formula One's 10 teams in champions Red Bull Racing and Italy-based AlphaTauri.
Both sides agreed a four-year extension to 2027 only last March.
Formula One chief executive Stefano Domenicali said the latest extension was a tribute to the "vision and passion" of Red Bull's late co-founder Dietrich Mateschitz, who died last October.
"The race in Austria is a big favourite for the drivers and all our fans and we are looking forward to many years of excitement and action that are ahead of us," he added in a statement.
