Jaguar XJ-S that won the
1985 James Hardie 1000 Hahne's first start in the
Australian classic was in
1984 when he partnered Englishman
Jeff Allam in a
Mobil Rover Racing Rover Vitesse to an easy
Group A class win and an excellent 12th outright after starting 36th against much more powerful opposition (the Rover qualified 10 seconds slower than the pole winning
Nissan Bluebird Turbo of
George Fury and finished just 11 laps down on the winning
V8 powered
Holden VK Commodore of
Peter Brock and
Larry Perkins). A brief return to Jaguar in 1985 saw Hahne team with Australian racer
John Goss to win the
1985 James Hardie 1000 after starting sixth. On the Bathurst podium, Hahne would call this his greatest win. Hahne's next time at Bathurst was in 1987 for the
World Touring Car Championship round in an ill-fated
Maserati Biturbo with Australian
Kevin Bartlett. A troubled race week saw them start 34th and retire after only 29 laps with a broken differential. 1988 saw him in a
Mark Petch Motorsport Ford Sierra RS500 with
New Zealand racer
Robbie Francevic, the car engineered by its previous owner and Hahne's team boss in the 1988 ETCC, former
Wolf Racing Formula One team owner
Walter Wolf. Their strong charge finished on lap 103 due to overheating after they had been in either second or third place for the previous 70 laps. That was Hahne's last race in the
Bathurst 1000. ==Racing career in Japan==
