Through the 1980s and into the 1990s, Williams F1 was a top running team, and technical director Patrick Head wasted no time in getting a contract signed. With a vastly superior budget, drivers and resources at his disposal, Newey and Head rapidly became the dominant design partnership of the early 1990s. By mid-season 1991, Newey's FW14 chassis was every bit a match for the previously dominant McLaren, but early season reliability issues and the efforts of Ayrton Senna prevented Williams team leader Nigel Mansell from taking the title.
