The Williams FW36 is a Formula 1 racing car designed by Williams Grand Prix Engineering to compete in the 2014 Formula One season. It was driven by Valtteri Bottas and Felipe Massa, who replaced the departing Pastor Maldonado. The FW36 was the first car built by Williams to use a Mercedes engine, a 1.6-litre V6 turbocharged unit, known as the PU106A Hybrid. It featured an extended nosecone dubbed the "anteater".

The FW36 was the first turbo powered Formula One car designed and raced by Williams since the Honda powered FW11B which carried Nelson Piquet and Nigel Mansell to first and second places respectively in the 1987 World Championship. The car immediately proved to be more competitive than its predecessor, consistently setting the quickest times in preseason testing. It was particularly fast in a straight line, thanks in part to the Mercedes power unit and in part to its low-drag design.

Over 19 races, the team scored 320 constructors' points in 2014 (compared to 5 in 2013), 9 podiums and 1 pole position - this secured them 3rd in the Constructors' Championship, 104 points ahead of Ferrari. The car was arguably the second fastest on the grid towards the end of the season as shown by the 2-3 in Abu Dhabi by Massa and Bottas respectively.

This very jacket was issues by Williams to Felipe Massa as an "interview Jacket" and used for promotional activities throughout the 2013 season. It is Made On Measurements (MOM) and has the driver's name on the inside tag. This jacket allowed to appear on camera with crisp sponsor logos vs. a dirty race used suit (particularly with the white team color for that year).
