It has a short main straight and most of the course consisted of tight, twisty corners so overtaking was extremely difficult. An example of this came when Gilles Villeneuve successfully defended his lead throughout the 1981 Spanish Grand Prix, despite a tail of four potentially faster cars. Villeneuve's turbocharged Ferrari 126CK, while powerful and fast on the straight, did not have as efficient ground effect aerodynamics as his pursuers - Jacques Laffite (V12 Ligier-Matra), John Watson (McLaren-Ford), Carlos Reutemann (Williams-Ford), and Elio de Angelis (Lotus-Ford) and was slower through the turns. This victory was to be the last one of Villeneuve's career.
