If you ever wanted to see the obvious difference between the way Group 44 and TWR built their Group C and IMSA V12 Jaguar race cars – this is a good way to do that.
Bob Tullius ran at Le Mans in 1984 and 85 for Jaguar and was hoping Jaguar would buy his chassis’ for to TWR to run.
Tom Walkinshaw wasn’t having that though, and (correctly) sold Jaguar Cars on the idea that his chassis was far more suitable to win Le Mans and the World Sportswear Championship.
Bob Tullius was using the older riveted aluminium tub, while TWR had moved on to composite fibre one-piece tubs which were lighter, stiffer and much more ‘today’s’ technology.
Here is a shot I took at Browns Lane in 2010 of one of the Le Mans Group 44 racers being restored, and the other is in 1987 showing the TWR chassis in the pits at Silverstone.
Of course, TWR would take over the U.S. operations of Jaguar’s racing program in 1988 and immediately win the Daytona 24 Hours race – and again in 1990.
Tom was in his best form then.
