In 1992, the track eliminated four corners to create the long right hander "Curva Sito Pons". Due to the hosting of the European Grand Prix in 1994, a new chicane was created (the "Senna" curve) at the corner where Martin Donnelly had a career-ending accident during qualifying for the 1990 Spanish Grand Prix. Jerez also hosted the 1997 European Grand Prix, which was the championship decider between Michael Schumacher and Jacques Villeneuve, who collided during the race.
