GMC Syclone

GMC Syclone (1991 )

The GMC Syclone was a high performance version of the GMC Sonoma pickups. It was produced in model years 1991 and 1992 and took 1992/1993 the same engine GMC Typhoon, based on the Jimmy forth. It was another high-performance version, the Sonoma GT. This offered less engine power, but was considered a sister model.

During its production time was the Syclone the fastest factory -made pickup in the world. Auto magazines compared its acceleration capability with a range of sports cars, including the Corvette and - in a well-known test of the Car and Driver - magazine - a Ferrari. The Syclone had a six-cylinder turbocharged engine, all-wheel drive, ABS for all four wheels - the equipment list was more like that of a Porsche than a pickup truck.

Both the Syclone and the Typhoon ( SyTy ) had an 8 cm ² turbocharger Mitsubishi TD06 -17C and a water / air intercooler by Garrett, with a 4.3 -liter Vortec V6 engine with special pistons, a special head gasket, a special intake system, a special injection system, a special exhaust system and 48 - carburettor housing were connected to two gas valves from the 5.7 -liter small-block V8. All SyTys had four levels of BorgWarner automatic 700R4 ( 4L60 ) and the all-wheel differential from the same manufacturer with a torque split of 35% ( front ) 65% ( rear axle). Both vehicles were sporting variations on the standard chassis and were in contrast to the large-scale models on which they are based, not for driving off-road designed. The Syclone was the first pickup factory manufactured with ABS on all four wheels. The power was 280 bhp (209 kW) and torque of 475 Nm. A new Syclone accelerates in 4.7 s 0-100 km / h and creates the quarter mile in 13.4 seconds with 156.8 km / h top speed.

In 1991 there were the Syclone in black only. The 1992er models were offered with a larger color palette before the production was stopped. 2995 Syclone were established in 1991 and 2200 pieces in 1992. 113 pieces were exported, of which 31 came back to the USA. Some Syclone also went to Saudi Arabia, where they were converted to metric sizes, a chip on leaded petrol and a silencer instead of the catalyst.

There were in 1991 two special editions privately produced:

• The Marlboro Syclone was - according to representation in Hemmings Muscle Machine - Magazine from January 2006 - the price of ten lucky winners of the 1992 Marlboro race. With the help of designer Larry Shinoda, who had designed the Corvette and the Boss Mustang, an amazing transformation of the ten black Syclone took place: ASC built the roof to the style of a Targa, the roof of which use could be mounted on the platform.
• ASC mounted a sliding window in the rear.
• There was a Guidon tonneau roof of sheet metal.
• Boyd Coddington Cobra wheels with Marlboro emblem on the axle caps and tires from Goodyear Eagle GS-C were mounted.
• Red " Hot Licks " color of PPG was applied.
• Graphics Concepts saw before running white stripes.
• Leather seats from Recaro were installed.
• There was a five-point racing network of Simpson ''.
• A Custom Momo " Evolution" steering wheel was installed.
• The cars had sound systems from Sony.
• The engine management system has been upgraded with a PROMPaq - performance chip.
• A suspension of BELL Tech provided a cut of up to 3 " (75 mm).
• The exhaust system was replaced with a stainless copy of Borla.

• Three Indy Syclone were used in the Indy 500 race on May 24, 1992. Your only change compared to the series was a sticker package. One of Indy pickups was rebuilt in the Syclone Pace Truck PPG if he was not also the official pace car. There have been significant changes in it, for example, a multi-color paintwork in silver, magenta and light blue, is firmly connected with the umbrella bulb holder, a fuel tank for racing and a fire extinguishing system.

Syclone, Typhoon and Sonoma GT were produced by Production Automotive Services in Troy (Michigan) built for GMC and sold through its dealer network.

The mechanics of the Syclone and Typhoon was previously used for the Pontiac Sunbird Turbo, which was stopped in 1990, a year before the Syclone appeared.
