The Buick Grand National was an unconventional car, to say the least. Rather than sticking with the traditional American muscle car formula of squeezing a large-displacement V8 under the hood, GM engineers tried something different: a V6 with a turbocharger. This configuration was a major risk, since turbochargers were still in their infancy when Buick launched the first turbocharged Regal model in 1978. But, after working through a steep learning curve, the configuration produced some astonishing results.
