The Typhoon arrived in the early 1990s with turbocharged power, all-wheel drive, and sports-car acceleration that embarrassed some of the era's most respected performance machines.Now one heavily modified example is taking that formula to an entirely different level. A black 1993 GMC Typhoon currently listed on Cars & Bids reportedly produces an astonishing 682 horsepower at the wheels, turning the already legendary SUV into something closer to a street-legal drag weapon.The numbers alone are enough to grab attention. A modern Dodge Durango SRT Hellcat may produce 710 horsepower from the factory, though this 30-year-old GMC could potentially surpass it once drivetrain losses are factored in. According to the seller, the Typhoon consistently ran mid-10-second quarter-mile times despite operating at Montana's higher elevations.AdvertisementAdvertisementWhether or not every claim fully survives dyno scrutiny, the build itself represents exactly the kind of over-the-top tuning culture that made the Typhoon iconic in the first place.The Typhoon Was Already Wild In Factory FormImage Credit: Cars & Bids.When GMC launched the Typhoon for the 1992 model year, the idea seemed almost absurd. Engineers took the compact Jimmy SUV platform, added a turbocharged and intercooled 4.3-liter V6, paired it with permanent all-wheel drive, and created one of the quickest American vehicles of its era.Factory output was rated at 285 horsepower and 350 pound-feet of torque, impressive numbers for the early 1990s. Contemporary road tests famously showed the Typhoon outrunning sports cars, including the Chevrolet Corvette, in straight-line acceleration.Only around 4,700 Typhoons were produced before GMC ended production in 1993. That rarity, combined with the SUV's cult status among enthusiasts, helped preserve its reputation as one of the earliest true high-performance SUVs ever built.AdvertisementAdvertisementEven today, a relatively stock Typhoon still feels unusual and special. This one, however, is nowhere close to stock.Nearly Everything Under The Hood Has Been ModifiedAccording to the listing, the Typhoon received a comprehensive engine build around 75,000 miles and now features an extensive collection of performance upgrades.The turbocharged 4.3-liter V6 uses upgraded internal engine components alongside a Precision turbocharger, aftermarket injectors, water-methanol injection, nitrous oxide, an MSD ignition system, and a custom ECU tune. The seller also reports upgraded transmission internals inside the 700R4 four-speed automatic transmission.An aftermarket exhaust system with electric cutouts helps the SUV deliver what is likely an extremely aggressive soundtrack under boost.AdvertisementAdvertisementThe listing claims the truck was dyno-tested at 682 wheel horsepower, though no dyno sheet accompanies the auction. Even allowing for some margin of error, the setup clearly represents a massive increase over the original factory figures.It Still Looks Like A Proper TyphoonOne of the most appealing aspects of the build is that it largely preserves the Typhoon's original appearance. Finished in black over a gray interior, the SUV still wears its factory-inspired body kit and maintains the understated look that made the original Typhoon so cool.The exterior does receive several updates, including HID headlights and 18-inch Kansei wheels wrapped in wider modern rubber. Inside, aftermarket gauge pods, upgraded speakers, and a Sony head unit modernize the cabin slightly without completely abandoning the 1990s atmosphere.The odometer currently shows roughly 81,700 miles, and the seller says the SUV was repainted in its factory color approximately six years ago.AdvertisementAdvertisementLike many heavily modified older performance vehicles, the Typhoon does come with a few imperfections. The listing mentions minor cosmetic wear, some underbody corrosion, and disconnected air-conditioning hardware, though the components reportedly remain with the vehicle.A Reminder Of How Ahead Of Its Time The Typhoon Really WasImage Credit: Cars & Bids.The current high bid remains surprisingly reasonable considering the level of modification and the Typhoon's growing collector appeal. Most relatively clean stock examples already command significant money thanks to their rarity and historical importance.Of course, buying a heavily modified 30-year-old turbocharged SUV producing nearly 700 wheel horsepower is not exactly a low-risk decision. Projects like this often come with quirks, maintenance surprises, and reliability questions that modern factory-built performance SUVs largely avoid.Still, that unpredictability is also part of the appeal. The Typhoon came from an era when automakers experimented with genuinely strange and exciting ideas, and this example pushes that spirit to its absolute limit.AdvertisementAdvertisementIn a world filled with increasingly sanitized high-performance SUVs, a boosted all-wheel-drive GMC from 1993 running 10-second quarter miles feels refreshingly unhinged.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
