Designed by Mike Coughlan, the A23 featured a Cosworth V10 engine, rather than the Asiatech unit used in the previous year's Arrows A22. The car bore the livery of the team's major sponsor, Orange. The car was completely designed around Jos Verstappen, who had a contract to race for the 2002 season. However, due to financial problems the team replaced him with Heinz-Harald Frentzen because he could bring more sponsorship money.
The Jaguar R1 was the chassis 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 R1 was the last F1 car that Johnny Herbert raced; the experienced Englishman retiring at the end of the season. It was also the car in which Luciano Burti made his race début.
