Michael Andretti's car, while his March 86C design won the CART title and 1986 Indianapolis 500 with Bobby Rahal. At the end of 1986 Newey joined the Haas Lola F1 team in an effort to improve its fortunes, but the team withdrew at the conclusion of the 1986 season. After a spell at Newman-Haas in 1987 working as Mario Andretti's race engineer, Newey was re-hired by March, this time to work in Formula One as chief designer. Formula One career March/Leyton House (1988–1990) Newey's first F1 design, the March 881, was far more competitive than many expected, with Ivan Capelli finishing second in Portugal, and even passing Alain Prost's McLaren-Honda turbo for the lead of the Japanese Grand Prix briefly on lap 16. As March became Leyton House Racing in , Newey gained promotion to the role of technical director. In France Capelli finished second after a late pass by Prost's Ferrari, but that proved to be the year's bright spot, with the team's results declining. In the summer of 1990, Newey was fired, although he soon found another role. Newey later said: "I was fired but I'd already made up my mind I was going – because once a team gets run by an accountant, it's time to move. Your self-confidence does suffer but Williams had approached me." Williams (1991–1996) 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. In 1992, there would be no problems, and with dominance of the sport not repeated until the Ferrari/Schumacher era, Mansell took the drivers' crown and Newey secured his first constructors' title. 1993 delivered a second, this time with Alain Prost at the wheel of the FW15C. 1994 saw a rare dip in performance for Newey-designed cars and the team and drivers struggled to match the Rory Byrne-designed Benetton B194 for pace and reliability. Disaster struck at the 1994 San Marino Grand Prix with the death of Ayrton Senna who had joined
