In the 1994 San Marino Grand Prix, during Friday practice Rubens Barrichello was launched over a curb and into the top of a tyre barrier at the Variante Bassa, knocking the Brazilian unconscious though quick medical intervention saved his life.
Another modification made to the Imola track is that of Variante Alta, which is situated at the top of the hill leading down to Rivazza and has the hardest braking point on the lap.
