Long before the Jeep Rubicon ever crushed its first grain of dirt, Mercedes-Benz built an unparalleled vehicle equipped with factory selectable lockers, massive tires, and portal axles that most kids can pedal a big wheel under. Part farm tractor, part people-mover, and all business, the Universal-Motorgert-or Unimog, as it's often referred to-is one of the original do-it-all wheelers. For most of us, having a GM pickup as a daily driver and an International Scout as a trail rig might sound like everything we need, but for Frank Navratil it was time for a change. With a strong admiration for the Unimog and looking for a more spacious wheeler, Frank sold both his rigs and imported the massive 416-series Unimog direct from Germany. Equipped with 46-inch tires, a naturally aspirated 5.7L diesel, and a unique torque-tube suspension, Frank's adventures crawling over the rocky-mountain terrain in Big Bear, California, were going to get a lot easier.
When we first caught up with this rare four-door on the trail, we were amazed at how easily the heavy Benz climbed hills. Though we cringed a bit when we learned of its 62-mph top speed and are still amazed at the sheer size of Frank's new daily driver, we can't stop thinking how badly we really don't need-but must have-one of these German monsters!
The Unimog's suspension works by connecting torque tubes from the transfer case to the differentials, which also protects and encases the driveshafts. Assisted by front and rear track bars to keep side-to-side movement in check, this setup is designed to prevent the suspension from binding under articulation and uses coil springs at each corner to allow the axles to travel. And since the 416s are something of a workhorse, two air-assisted calipers are on each front wheel to stop the rig and whatever its heavy cargo may be.
The Unimog's portal axles are extremely stout, largely in part because they transfer the workload through internal gear reduction. As the driveshaft spins, it rotates the 3.14 ratio ring-and-pinion, which sends power to the 2.07 gears in the portal boxes, thus creating an end ratio of 6.52. | 
No crazy electronics here, but we'd probably need to take a minute or two to learn all the levers! With six forward and two reverse gears, this '79 416-series Benz has more in common with a tractor than any of its luxury brethren. |
Who needs eight cupholders when you have a three-way tilt bed, selectable air lockers, and 46-inch-tall tires direct from the factory? But before you run out and trade in your pickup, know that with a top speed of 62 mph and weighing it at around 9,000 pounds, this might not be the best pick if you are addicted to speed and short on patience. | |
