As Honda withdrew from the sport at end of 1992 due to their entrance into CART PPG Indy Car World Series in 1993, McLaren sought a new engine supplier. A deal to secure Renault engines fell through, subsequently McLaren switched to customer Ford engines for the season. Senna—who initially agreed only to a race-by-race contract before later signing for the whole year—won five races, including a record-breaking sixth victory at Monaco and a win at the European Grand Prix, where he went from fifth to first on the opening lap. His teammate, 1991 IndyCar champion Michael Andretti, fared much worse: he scored only seven points, and was replaced by test driver Mika Häkkinen for the final three rounds of the season. Williams ultimately won both titles and Senna—who had flirted with moving there for 1993—signed with them for the season. During the 1993 season McLaren took part in a seven part BBC Television documentary called "A Season With McLaren".
