The Bahrain Grand Prix organisers expect all living world champions to attend this year's Sakhir race.
The 20 title-winners have been invited as part of the celebrations of the Formula 1 world championship's 60th anniversary.
"This will be a truly special occasion, especially for all those who love F1 and who have been following the sport for many years," said circuit boss Martin Whitaker.
Many of the cars associated with the champion drivers will also be brought to Sakhir for the occasion.
The Bahrain GP has moved back to the season-opener slot this year and will take place on 14 March.
