All but six of Senna's 41 victories were for McLaren, and 32 of his wins were in cars with a Honda engine. Of his remaining nine victories, five were achieved with Ford powered cars, and four with Renault. He was most successful at Monaco, where he won six times during his career, including a record five consecutive times between 1989 and 1993. His largest margin of victory was 1:23.199 at the 1993 European Grand Prix, while the narrowest margin was at the 1986 Spanish Grand Prix, when he beat Nigel Mansell by 0.014 seconds, one of the closest finishes in Formula One.
