The Jaguar XJR-5 is a IMSA GTP sports prototype race car, designed, developed and built by Group 44 racing for Jaguar with the aim of competing, from 1982, in the IMSA GT Championship.
[1][2][3][4] In the late 1970s, CEO John Egan wanted to initiate a racing program to boost sales of the Jaguar which was falling sharply at that historic time, especially in the US market.
So he consulted Jaguar executive director in the United States Mike Dale about a car for IMSA's new GTP prototype class and the 24 Hours of Le Mans.
Bob Tullius and his Group 44 team were contacted after the Triumph TR8 racing program had just ended.
The car was designed by Lee Dykstra, together with Max Schenkel and Randy Wittine, who were experts in aerodynamics.
