When the Mercedes G63 6x6 just won’t do

LISTEN 06:34

Big trucks are all the rage these days. Not just big, though, really big. The Devel Sixty is the latest six-wheeled monster to the scene and it comes from a company best known for the outlandish, 5000-horsepower Sixteen. The new truck has seating for six people inside its aircraft-like cabin accessed by an aircraft-like door. Devel debuted the Sixty at the recent 2017 Dubai Auto Show, which is a logical place to debut something so illogical.

Detailed specs are few and far between, but Devel does say the Sixty is powered by a 6.7-liter V-8 turbodiesel making 720 horsepower and 737 pound-feet of torque. The Sixty also has military-style wheels with a Central Tire Inflation System that allows for changes in tire pressure on the move. And in low pressure in the knobby tires isn’t enough to blast through mud or sand, the Sixty has a winch at each end for recovery.

The front looks like nothing we’ve seen before and takes a big departure away from conventional design layouts

The Devel Sixty looks like something from some cheesy Michael Bay flick. It’s extraterrestrial proportions and menacing black paint give it an ominous, if not villainous appearance. The front looks like nothing we’ve seen before and takes a big departure away from conventional design layouts. The long, boxy body leads to an angular rear end with LED light strips for tail and brake lights. Big D-ring shackles serve as easy recovery points for pulling stranded vehicles to solid ground.

The Sixty rides on Continental MPT 81 tires sized in something over 40 inches tall. They’re mounted on multi-piece beadlock wheels that incorporate the tire inflation system. Ground clearance is best measured in feet.


  • Room for six people
  • Likely finished in high-end materials

Note: Devel Sixteen pictured here.

Devel hasn’t shown any interior photos of the Sixty, so the cabin is still a mystery. We do know it seats six people and access is gained via a folding door on the driver’s side reminiscent of a private jet’s door that turns into a staircase. Regardless of the lack of details, expect the interior to be awashed in leather and high-end finishes. This thing isn’t cheap, so its interior will have to match the price tag. Keep reading for that amount.

Powering this beast is a 6.7-liter V-8 turbodiesel making a respectable 720 horsepower and 737 pound-feet of torque

Powering this beast is a 6.7-liter V-8 turbodiesel making a respectable 720 horsepower and 737 pound-feet of torque. That’s enough to push this six-wheeled wonder to 60 mph in just 5.8 seconds and to a governed top speed of 93 mph. Devel didn’t announce information on the transmission, transfer case, differentials, or where the powertrain is sourced. Our bed is Ford since it makes a 6.7-liter V-8 turbodiesel in the U.S., which conveniently, is also where Devel is based.

Devel does say the Sixty has an independent suspension system and portal axles, but from the photos we see, we’re thinking that might not be true. In fact, the front axle looks suspiciously like the solid front axle on a Ford Super Duty, which is not a portal design. The rear suspension clearly has leaf springs spanning between the two axles, making them not independent.

We hate to say it, but the clues point to the Devel Sixty being nothing more than a rebodied Super Duty with an extra axle added on. After all, only Ford makes a 6.7-liter V-8 turbodiesel and aftermarket tuning kits can easily increase power past 700 horses. We’ve reached out to Devel for clarification.

Big trucks aren’t cheap and the Devel Sixty is no different. It starts at $450,000. Orders will take roughly a year to fulfill and it isn’t clear if Devel has sold any. Since the debut happened in Dubai, though, we’re betting at least a handful were preordered by some oil tycoons.

Perhaps the most popular 6x6 is Mercedes’ outlandish G63 6x6 it launched for 2014. It’s based on the G-Class and adds another axle under a lengthened chassis. There’s also a cargo bed for hauling all the expendable income somebody must have to buy something so ridiculous – though we’d probably buy one, too, given the chance.

The G63 6x6 is powered by a twin-turbocharged 5.5-liter V-8 making 536 horsepower and 561 pound-feet of torque. The Mercedes features portal axles for improved ground clearance without a tall suspension. It also has five differential locks. Add on 37-inch-tall mud tires, and the 6x6 is basically unstoppable – unless you high-center it.

Mercedes is extremely proud of its six-wheeled creation. In 2013, the price was $511,000, but the limited supply of 100 examples has seen pre-owned 6x6s selling for nearly $1 million.

Devel is known for off-the-wall vehicles, namely the Sixteen concept seen several years ago. Along the Sixty came the new version of the Sixteen, meaning Devel has been busy at the drawing board. The U.S.-based company could position itself as the go-to automaker for all things extreme, should it play its cards right. It’ll be interesting to see how things play out.

  • Leave it
    • Few details at this point
    • $450,000 is expensive
    • Could it be a rebodied Ford Super Duty?
