GMC Syclone

A turbocharged, AWD compact pickup that outran Ferraris—and changed what trucks were allowed to be.

The GMC Syclone is a 1991 high-performance compact pickup based on the GMC Sonoma. Built by GMC and Production Automotive Services (PAS), it featured a 4.3L turbocharged V6, 4L60 automatic transmission, BorgWarner 4472 AWD transfer case (35/65 torque split), Mitsubishi turbo, Garrett intercooler, and 4-wheel ABS. At launch, it was the fastest stock pickup in the world—and its acceleration outperformed the Chevrolet Corvette and Ferrari 348 ts. It established that AWD and forced induction could coexist in a production truck without sacrificing usability. It did not offer a manual, nor did it prioritise ride comfort or cabin isolation. Its legacy is mechanical audacity, not longevity or luxury.

Chapters & takeaways4
  1. 1:08
    Origin Story

    It is not a concept or a prototype—it is a factory-sanctioned, PAS-built variant of the GMC Sonoma, sold new in 1991.

  2. 2:32
    Drivetrain Architecture

    Its drivetrain is a purpose-built chain: turbocharged V6 → 4L60 auto → BorgWarner AWD case splitting torque 35/65.

    Performance Benchmark

    At launch, it was the fastest stock pickup in the world—and its 0–60 time beat both the Corvette and Ferrari 348 ts.

    Braking & Control

    Four-wheel anti-lock brakes were standard—a rarity in trucks at the time, and essential for managing its output.

Worth your time?

Yes. Drive the whole thing.

The written brief1 min read

What the car is and where it came from

It is a high-performance version of the GMC Sonoma compact pickup truck. Produced in 1991 by GMC and Production Automotive Services (PAS).

How it works, in terms someone would actually use

It sends power through a 4L60 4-speed automatic to a BorgWarner 4472 transfer case that splits torque 35% front / 65% rear. The 4.3L turbocharged V6 uses a Mitsubishi TD06-17C turbo and Garrett water/air intercooler. Four-wheel anti-lock brakes manage stopping.

What it gets right

It gets right the integration of forced induction and all-wheel drive into a short-wheelbase pickup body. It delivers immediate, street-usable thrust with no driveline compromise for daily use.

What it does not

It does not offer manual transmission. It does not use rear-wheel drive. It does not have a V8. It does not isolate the driver from body roll or turbo lag.

What it changed

It redefined what a production pickup could do: it proved AWD, turbocharging, and intercooling belonged in a mass-market truck chassis—not just sports cars or rally machines.

Who it is for, and who it is not

It is for enthusiasts who prioritise acceleration, drivetrain novelty, and factory-built audacity over comfort, refinement, or resale logic. It is not for collectors seeking rarity alone—2,998 units were built—or for drivers needing payload, towing, or cabin quiet.

Is it worth your time

Yes—if you want proof that a compact pickup can out-accelerate a Ferrari 348 ts and Chevrolet Corvette in 1991, and you value mechanical specificity over polish or longevity.

Citroën 2CVFlaminio Bertoni · 1948The Citroën 2CV is a French economy car conceived by Pierre Boulanger to motorise rural farmers, featuring innovative engineering, utilitarian design, low cost of ownership, minimal fuel consumption, and a long-travel suspension enabling it to cross ploughed fields without breaking eggs. It was often called 'an umbrella on wheels', introduced Michelin's radial tyres, and over 3.8 million units were produced from 1948 to 1990. Its body style is a fixed-profile convertible; it has an air-cooled engine; layout is front-engine, front-wheel drive; and production spanned 1948–1990.

Production occurred at AM General’s Mishawaka, Indiana facility, and ended in June 2006 due to impending diesel emissions regulations. The vehicle was offered in several body styles including soft top, four-door hard top Sport Utility Truck, and Alpha Wagon.
