Watch: The GMC Syclone Has No Competition by Sebastien Bell May 14, 2018 Share Comments Being the oldest motoring magazine on television, MotoroWeek’s format is pretty much set in stone. But every once in a while, an automaker makes something that’s so odd or unusual that it messes with the whole program. Enter the ’91 GMC Syclone. Based on the GMC Sonoma and fitted with a 280 hp/350 lb-ft, 4.3-liter turbocharged V6 sent to an all-wheel drive system that first saw use in minivans, the truck was a peculiarity when it came out, to say the least. Although it’s now known as a classic, way back in 1991 it was a little more difficult to reckon with. And of course it would be. Despite espousing some thoroughly modern ideas (AWD, sport truck, turbocharging, seats with inflatable lumbar support!) there are some very old-fashioned ideas, like rear drum brakes. But John Lindo sums it up about right when he says “The Syclone is one of the most impractical rides on the planet, but it’s also one that will be wind-burned in our memories for a long time to come.” And while you’re at it, have a GMC Typhoon review, too.
