How do you make a Ford F-150 Raptor any more awesome? Hennessey Performance has a great answer – stick an extra axle under an elongated cargo bed then add 150 horsepower. Hennessey is no stranger to making outlandish vehicles with insane levels of power. The Texas-based tuner has done several Raptor upgrades before, and naturally, their bread-n-butter is adding more horsepower to stock vehicles. But this marks the first time a 6x6 configuration has been involved.
