1990 United States Grand Prix

The 1990 United States Grand Prix was the opening motor race of the 1990 Formula One World Championship held on March 11, 1990, in Phoenix, Arizona. It was the 32nd United States Grand Prix since the American Grand Prize was first held in 1908, and the 25th under Formula One regulations since the first United States Grand Prix was held at Sebring, Florida in 1959. It was the second to be held on the Phoenix Street Circuit and ran over 72 laps of the 3.800 km (2.361 mi) circuit.

The race was won by Brazilian Ayrton Senna, driving a McLaren MP4/5B by eight seconds over French driver Jean Alesi in his comparatively under-funded Tyrrell 018.

It was Alesi's first podium finish, with Belgian driver Thierry Boutsen in a Williams FW13B coming home third.
