In 1991, Production Automotive Services began producing the first of 4,697 Typhoons for GMC, using that year's Jimmy SUV as the platform. They added a Mitsubishi turbocharger, Garrett intercooler, revised intake and exhaust systems, and a new throttle body. The new, custom all-wheel-drive configuration produced a 35 front, 65 rear torque split and modifications to the brakes, differential, and suspension. The end result was a 0-60 mph time of 5.3 seconds and a GMC Jimmy, which could probably satisfy the owner's desire for one of those impractical sports cars.
