The Jaguar R1 (originally known as the Stewart SF4) is the car with which the Jaguar Racing Formula One team competed in the 2000 Formula One season, and the first Jaguar-badged car after Ford's purchase of the Stewart team the previous year.
The car proved largely disappointing, despite flashes of promise, especially in the hands of Eddie Irvine, who was regularly able to qualify the car in the top ten. The car's race pace was often poor and it suffered from an unreliable gearbox. Irvine, the championship runner-up, could only score 4 points, placing the team ninth overall in the Constructors' Championship.
The R1 was the last F1 car that Johnny Herbert raced; the experienced Englishman retiring at the end of the season after a difficult campaign, his final race in Malaysia ended in a frightening accident caused by suspension failure from which he was lucky to escape with minor injuries. It was also the car in which Luciano Burti made his race début when he substituted for Irvine in Austria.
Tiff Needell became the fourth person to drive the car when he drove it before the Spanish Grand Prix as part of a segment for the TV show Top Gear.[1]
