From supercharger upgrades to full performance conversions, Hennessey transforms vehicles from Ford, Chevrolet, GMC, Ram and other American marques. At Grand Touring Automobiles in Toronto, we help drivers across the GTA explore Hennessey upgrades, custom builds and performance vehicles available in Canada. Depending on the model and package, upgrades can include increased engine output, suspension, braking, wheels and exterior enhancements.
Hennessey’s work also reaches beyond modifying other manufacturers’ vehicles. Its Venom F5, developed by Hennessey Special Vehicles, is a purpose-built hypercar with a twin-turbocharged V8 producing a stated 1,817 horsepower. It represents the brand’s ambition at its most extreme: creating a complete high-performance vehicle from the ground up.
