At SEMA the specialty manufacturer Hennessey debuted the 2018 Ford Raptor 6x6. You know, when four wheel just aren't enough.

The $349,000 price tag includes the donor 2018 Raptor four-door truck and adds a twin-turbo engine spitting out 605 horsepower and 622 pound-feet of torque. That's enough to hustle this monster from 0 to 60 miles an hour in 4.9 seconds. Not bad for something that is too large to park in most underground garages.

Now playing: Watch this: 2018 Hennessey Ford Velociraptor 6x6 is a Raptor in beast...

The rear axles still lock to provide better traction in dirty situations, but the VelociRaptor has 10 inches of ground clearance over a stock Raptor. Wheel size is upped to 20 inches, wearing Toyo Open Country rubber. Aesthetic goodies include special front and rear bumpers, a roll bar and all the LED lights you could ever need.

There is one option on the VelociRaptor: a $22,000 upgraded six-caliper Brembo brake system.

Up until this point, Mercedes-Benz has been the only option for a ridiculous 6x6 vehicle, and it isn't available in the US. Hennessey will make 50 of the gargantuan 6x6 Ford trucks and has already presold a handful.

Watch out, Mercedes, there's another contender for the six-wheel crown.
