Every once in awhile, you meet people who are masters at thinking stuff up. The team from GMPartsOnline.net is like this, having come way out of left field with one of the most interesting comparisons we have ever seen.
A 1991 GMC Syclone versus a 2017 Camaro SS 1LE.
“We were talking about our favorite vehicles one day at work when someone mentioned the Syclone,” recalled Angel Vigil, Director of GMPartsOnline.net. “Then we had an argument about whether or not the Syclone was faster than a new Camaro.”
Black Knights
From the onset, it doesn’t seem like much of a debate but looks are deceiving. The Camaro, despite modern technology and advanced aerodynamics, only hits 60 mph two tenths of a second quicker than the old Syclone. This lead Vigil and his team to wonder: if the Syclone had the advantage of GM’s newer powertrains, would it be able to best the Camaro?
“The truck was obviously very fast, but the turbo 4.3-liter is a very special engine,” Vigil said. “You can’t find it in any other GM vehicle, other than the Typhoon.”
The Typhoon, like the Syclone, was a short-lived performance version of the GMC Jimmy. The Typhoon ruled the streets from 1991 to 1993, whereas the Syclone saw only one year and one color: 1991 and black.
“The truck was very expensive, and it was a hard purchase to justify if you didn’t love the idea of owning a hot rod pickup,” Vigil explained. “I always wanted one when I first heard about them, but like most people, I suppose I wasn’t in a position to buy one new.”
When the Syclone’s original MSRP is adjusted for inflation, it jumps to $47,278 compared to the 2017 Camaro SS 1LE at $44,400.

Golden Opportunities
To this day, the 1991 GMC Syclone is one of the quickest production trucks ever built. Interesting enough, the Syclone was actually born a Buick when, after the Grand National was halted, engineers from the program stuffed the car’s 3.8-liter plant into a Chevy S-10. Billed as the Grand National Pickup, it was presented to GM brass but they were hardly enthusiastic.
After putting the brakes on the Grand National car, they had other plans for Buick. A performance-oriented truck was not in the cards.
The team then approached Chevrolet’s management, but they already had the 454 SS Sport Truck and were not taking any chances. According to veteran automotive journalist Marty Schorr, the Buick Grand National was stealing the Corvette’s thunder at the time. Schorr detailed the story for us earlier this year, revealing how a bumper sticker for the Grand National that read “we brake for Corvettes” caused a lot of headache for Chevy officials.
It was unlikely Chevy was going to be outdone by Buick again.
This left GMC who immediately jumped at the opportunity.

Power & Performance
Under the hood, the aforementioned 4.3-liter turbo V6 created 280 horsepower and 355 lb-ft. of torque. To put that into context, the 1991 Corvette L98 engine produced 250 horsepower and 350 lb-ft. of torque. Rumors swirled that the Syclone’s motor was bumped down as to not encroach on the Corvette ZR-1 LT5 engine, which produced 375 horsepower and 370 lb-ft. of torque.
The all-wheel drive system that propelled the Syclone was ahead of the curve too. With an advanced viscous-coupled center differential and limited slip rear differential, power could be split 35/65 front to rear for maximum traction. GMC’s tiny hurricane rode on 16×8-inch aluminum wheels with 245/50/16 Firestone Firehawk tires.
“The truck was also very light,” Vigil added. “That’s always something performance enthusiasts appreciated.”
The GMC Syclone tipped the scales at 3,525 lbs., nearly 250 lbs. lighter than the 2017 Camaro SS 1LE with the track package. The Camaro makes up the difference with more grunt – it’s optional 6.2-liter V8 cranks out 455 horsepower and 455 lb-ft. of torque.
“The heritage is probably the thing I love the most about the Camaro, but the car has real race credibility too,” Vigil said. “And the 6.2 V8 is awesome.”
Sneaking Suspicions & Rare Birds
It’s hard to say what would have become of the GMC Syclone had it survived the early 90s, but Vigil has an idea.
“If GM wanted to take the Colorado or Canyon and offer the twin-turbo 3.6-liter used in the Cadillac CTS, that would be a 420 horsepower engine that would probably fit in the engine bay,” he said. “That truck would run with a new Camaro SS too I suspect, only it would weigh 500 lbs. more than the Camaro SS.”
The chart from GMPartsOnline.net comparing the Syclone and Camaro is below, with one you can share on social media here. Although it has already been sold, RK Motors Charlotte has some stunning photos of a 1991 GMC Syclone, including pictures of the truck’s window sticker and owner’s manual.
The Syclones were produced only sparingly before being sent to pasture; the Camaro celebrated 50 years in 2017.
“There were only about 3,000 of them made,” Vigil said. “They’re highly collectible.”
