Hennessey has turned its tuners on the best-selling Ford F-150 for its latest entry in its Ford-themed Heritage Edition, and the result is this: a truck swathed gaudily in bright red paint and highlighted with white racing stripes and numbers that nearly double output to 768 horsepower.

The upgrade is available only on 2018-2019 F-150s equipped with the 5.0-liter V8, which normally does 395 hp and 400 pound-feet of torque.

But Hennessey adds a 2.9-liter supercharger and other tweaks, including increased boost pressure, and air-to-water intercooler and a fuel injector upgrade, that takes power to 768 hp at 7,000 rpm, making it more powerful than the Ford GT.

Other features include stainless steel cat-back exhaust, a dyno-tuned chassis and Hennessey Performance Engineering engine management calibration.

You also get a serial-numbered dash and engine plaques, Hennessey exterior badges and embroidery on the headrests.

There are also off-road upgrades including Hennessey front and rear bumpers with five LED lights embedded in the front ones, 20-inch 10-spoke wheels, 35-inch off-road tires and a front suspension levelling kit for an overall lift of 3 inches.

The upgrades start at $74,500/£57,000+VAT which is inclusive of the cost of the new F-150.
