First Sight: Holden Torana concept

Holden has stolen the limelight at the opening of the Australian International Motor Show in Sydney, unveiling a ground-up concept car dubbed the Torana TT36. The concept revives a famous Australian nameplate from the 1970s - appropriate since, like the original Torana, it features rear wheel drive and a six cylinder engine. That's where the similarities end, however, as the new Torana's engine is an experimental 280kW/490Nm twin turbocharged version of the new global V6 Holden has begun manufacturing for various parts of the GM world and which will eventually be used by Alfa Romeo.

The thing that really sets him apart is that, while competitors shared driving duties over the long desert courses, Stewart did the vast majority of them alone, with no relief drivers--just him and the dirty, dusty desert. But even legends want to retire someday.
