Who are the drivers in the 2013 Williams formula 1 team?

Currently there are no American drivers in Formula One. However from 2006 to 2007 American Scott Speed from Manteca, CA drove for Scuderia Toro Rosso, a satellite team owned by Red Bull.

The last podium by an American driver was Michael Andretti at the 1993 San Marino Grand Prix in Imola, Italy at Il Autodromo Enzo e Dino Ferrari.

The last American World Driver's Champion was Mario Andretti in 1978, who drove for Lotus.

Other than the elder Andretti, the only other American World Driver's Champion was Phil Hill who took the title in 1961 in a Ferrari.

However, Dan Gurney remains the only American to drive and win a Grand Prix in a car of his own design; winning the 1967 Belgian Grand Prix at Spa Francorchamps in his Eagle-Westlake.
