An interesting tidbit, from 1990-1997, there were four different winners of the Mid-Ohio CART Champ Car race, all of which were back-to-back.
1990-91: Michael Andretti
1992-93: Emerson Fittipaldi
1994-95: Al Unser Jr.
1996-97: Alex Zanardi
There have been two other drivers who won this race back-to-back, Bobby Rahal in 1985-86 and Helio Castroneves in 2000-01. Don't beleive me? Check this out:
