An extra, third axle increases the number of wheels by 50 per cent, with both rear axles featuring locking diffs to aid off-road driving. The suspension is also modified and there are new front and rear bumpers, LED roof lamps, roll bar, and bigger, 20-inch tyres – wrapped in off-road rubber.
The Raptor’s twin-turbocharged V6 engine, exhaust system, and intercooler system are all upgraded, lifting power from 336kW to a dyno-soaring 450kW (Hennessey quotes 600-plus horsepower).
Owners of the regular Raptor can purchase the performance-enhancement package separately, for a cost of $22,500 (A$30,000).
The cost of the full Velociraptor package will put a meteor-sized hole in your wallet, though.
At $295,000 (A$390,000), the six-wheeled utility vehicle costs about six times the price of the standard F-150 Raptor SuperCrew.
And this doesn’t include additional options such as Brembo brakes, customised interior, larger wheel/tyre packages, and even armouring systems.
The Hennessey Velociraptor 6x6 is still more affordable than the equivalent model from Mercedes-Benz – the G63 AMG 6x6 introduced in Europe in 2013 at a converted price of about $550,000.
The G63 isn’t quite as powerful, though, with its 5.5-litre twin-turbo V8 producing 400kW.
