2001 San Marino Grand Prix

The 2001 San Marino Grand Prix (formally the Gran Premio Warsteiner di San Marino 2001) was a Formula One motor race held at the Autodromo Enzo e Dino Ferrari, Imola, Emilia-Romagna, Italy on 15 April 2001. It was the fourth race of the 2001 Formula One season. The 62-lap race was won by Ralf Schumacher driving a Williams-BMW after starting from third position. David Coulthard, who started the Grand Prix from pole position, finished second in a McLaren-Mercedes, while Rubens Barrichello finished third in a Ferrari. Schumacher's win was the first of his Formula One career and the first for Williams since Jacques Villeneuve won the 1997 Luxembourg Grand Prix. The race also represented the first win for French tyre manufacturer Michelin in Formula One since the 1984 Portuguese Grand Prix and the first race since the 1998 Italian Grand Prix not won by Bridgestone.

Second place put Coulthard level on points with Ferrari driver Michael Schumacher in the Drivers' Championship, with both drivers on 26 points after Schumacher retired from the race. In the Constructors' Championship, McLaren reduced Ferrari's lead to 10 points. This was the last race for Gastón Mazzacane.

This event also marked the last time until the 2008 Australian Grand Prix that cars competed without using traction control, which was reintroduced at the next race, and the last race until the 2004 Australian Grand Prix not to feature cars competing with fully-automatic gearboxes and launch control, which were also reintroduced at the next race. These electronic driver aids were reintroduced to ensure no teams were using these systems illegally to gain a competitive advantage.
