Williams FW34

The Williams FW34 was a Formula One racing car designed by Williams F1 for the 2012 Formula One season.

Design

Following their worst season in their thirty-year history—in which they finished ninth in the World Constructors' Championship with just five points—the team underwent a technical review, employing former McLaren designer Mike Coughlan as Chief Designer, and promoting Jason Somerville to Head of Aerodynamics.
The FW34 used the Renault RS27-2012 engine; the team had previously used Renault engines between 1989 and 1997. The car, which was launched on the 7 February 2012, was driven by Pastor Maldonado and Bruno Senna.

Racing history

At the 2012 Spanish Grand Prix, Maldonado drove the FW34 to pole position and converted it to victory the next day. It was Maldonado's first and only Formula One race win, Williams' first race win since Juan Pablo Montoya won the 2004 Brazilian Grand Prix driving an FW26, and Williams' most recent race win as of October 2025.

Livery

Drawing the inspiration from the Rothmans-sponsored FW19 of 1997, the blue colour on the engine cover was flipped along with other minor changes. PDVSA was retained for the second year with new sponsorships from Procter & Gamble products.
