2011 Williams FW33

The 2011 Williams FW33 featured a few new developments. The seven-gear speed box inside the car boasts the smallest ever produced by Williams and works in conjunction with the new pull rod suspension.

A controversial rule change for 2011 saw the Williams team include the moveable rear wing, which should have made overtaking a lot easier. Another change was returning to the use of Kinetic Energy Recovery Systems (KERS), which they packaged in the car’s survival cell, below the fuel tank. This was also implemented with the hopes of giving the car a much better start.

The FW33 made its debut at the 2011 Australian Grand Prix where Brazilian racing veteran Rubens Barrichello and Venezuelan rookie driver Pastor Maldonado drove it. Maldonado would secure his first Grand Prix win a year later for the Williams team at the Spanish Grand Prix.

While this racecar faced a number of technical issues during its debut season, by the end of the season, the FW33 racked up 5 points, placing Williams in 9th position at the Constructor Championships.

The legendary FW33 has secured its place in F1 history.
