The odds were not on Tullius' side as he faced three brand new Chevrolet Corvette on his own. He placed a disappointing ninth but bounced back with a second at Westwood and a third at Portland. The 1978 XJ-S then scored a breakthrough victory at St. Jovite.
With the first victory under his belt, Tullius would continue his winning ways, scoring a remarkable seven victories in a row. After his victory in round eight at Road America, he had earned enough points to successfully defend his driver's title but it would take until his win in round ten in Mexico City before the manufacturer's title for Jaguar was also secured.
Tullius raced the car one more time at the IMSA season final in Daytona, where he ran as high as third overall against 935s before a power steering issue dropped him down to nineth. The 1978 Group 44 XJ-S remains as one of the most successful Jaguar racing cars, scoring more outright victories in a single season than any other chassis in the British manufacturer's long and rich competition history. << Prev Page 2 of 2
