Hennessey building 50 VelociRaptor 6x6 trucks at $349,000 apiece

The truck is a stretched version of the Ford F-150 Raptor that picks up a third axle. Besides the additional axle, the truck's twin-turbo V6 gets an engine upgrade in the form of modified turbo wastegates, a new intake, intercooler, exhaust and a retuned engine computer. The results are a V6 making 602 horsepower and 622 pound-feet of torque. Hennessey claims the engine can hustle the big truck to 60 mph in 4.9 seconds.

There are a number of other upgrades throughout. Hennessey says all three axles can be locked for maximum traction. The suspension is upgraded, and the new 20-inch wheels are wrapped in off-road tires. Appearance-wise the truck gets a style bar, off-road bumpers front and rear, and LED off-road lights in the bumpers and on the roof. Hennessey also offers an optional brake package with six-piston Brembo calipers. It's probably a worthwhile investment, since this truck is probably extraordinarily heavy.

The brake package, and the truck for that matter, aren't cheap. The VelociRaptor 6x6 starts at $349,000, and the brake package adds another $22,000. That price is also greater than the 2016 estimate of $295,000. But for the money, you're getting a highly unusual truck with lots of custom work, as well as a good amount of exclusivity. The company says it's only building 50.
