For me, it was Volvo who reinvented turbocharging, not Saab or Porsche or Buick. The idea of slapping a hair drier on a Flying Block of Flats more or less made Volvo an overnight sensation with the Volvo 244 and 242 Turbo and 242/244 GLT Turbo 2.1 Turbo 1980 - 1982. And then in 1983, a sporting evolution verision, the 240 Turbo with a larger turbocharger and other performance modifications. All of these special cars were reputedly exported to the United States. Most of them were subsequently stripped of their racing equipment and sold as standard road cars, which later led Volvo into difficulties with the sport's governing body, the FIA, which questioned whether the necessary 500 cars had in fact been built. Debate continues to this day among enthusiasts about how many of the special-edition cars were built and what happened to them.
It wasn't well publicised like the 242 GT, but when raced in Asia, Europe and Australia and new Zealand, it ended up in front of Turbo Merkurs and V8 Mustangs and M3 BMW's...racing was stood on its ear.The Eggenberger Motorsport team was the most successful of these. One of their cars, driven by Gianfranco Brancatelli and Thomas Lindstrom, won the 1985 European Touring Car Championship outright!
Then an Australian Dealer Team car driven by the New Zealander Robbie Francevic won the 1986 Australian Touring Car Championship and the Wellington 500 street race in New Zealand. The car also won the Guia Race in Macau consecutively in 1985 and 1986. Volvo withdrew from the sport at the end of the 1986 season, partly because of the controversy over its adherence to the rules, but also because the 240 had achieved what it set out to do..
