Only 19 examples are being made.
Back in 2018, Hennessey introduced the Heritage Edition Mustang to celebrate building its 10,000th car. Since then, the Texas tuner has continued modifying Mustangs with extreme power upgrades. Even the Mustang Shelby GT500 was given the Hennessey Performance treatment.
In stock form, the GT500 is the most powerful Mustang Ford has ever built, but that didn't stop Hennessey from cranking up the power to an insane 1,200 horsepower. Hennessey's Heritage Edition Mustang has returned for 2021. To show us what it's capable of, the tuner has released a video showing the muscle car burn some rubber.
Based on the Ford Mustang GT, the Heritage Edition produces 808 horsepower and 677 lb-ft of torque. That's a substantial upgrade over the standard Mustang GT that generates 460 hp and 420 lb-ft of torque. To achieve this, Hennessey upgrades the powertrain with a 3.0-liter supercharger system, an air to water intercooler system, and an upgraded fuel pump and fuel injectors. As a result, the Heritage Edition Mustang will accelerate from 0-62 mph in 3.3 seconds, matching the sprint time of the 2020 Mustang Shelby GT500.
Reworked suspension brings the Heritage Edition Mustang lower to the ground and the car rides on 20-inch alloy wheels wrapped in Michelin Pilot Sport Cup2 tires.
Inspired by the Ford GT Heritage Edition, Hennessey's Mustang Heritage Edition is finished in Race Red and features a racing livery that pays tribute to legendary Ford GT race cars. Other visual modifications include a carbon fiber splitter, side sills, rear spoiler, and a stainless-steel exhaust system. Inside, the Heritage Edition features headrests with an embroidered Hennessey logo.
It isn't clear how many cars have been built since it was introduced in 2018, but the Hennessey Heritage Edition is limited to just 19 examples. Each car contains a serial numbered dash plaque and engine plaque showcasing the build number.
