The Unimog as an Expedition Vehicle
Unimogs make excellent expedition vehicles because of their rugged
design, off-road capability, and Mercedes-Benz quality. Compared
to Land Rovers or Land Cruisers, Unimogs provide much more room
and cargo capacity. Expedition vehicles based on American pickups
don’t even come close to a Unimog in terms of capability and
When the going gets really tough, the Unimog is in a league of
its own. Its extraordinary off-road ability and heavy-duty components,
allow it to reliably access areas other vehicles cannot even approach.
The extra capacity allows for a level of freedom, comfort and independence
unattainable in other vehicles. Extra fuel, water and storage capacity
means the Unimog has incredible range and can carry supplies for
extended periods away from civilization.
Of course different types of Unimogs have different pros and cons,
and some types are more suited to expeditions than others. Here
is a brief overview of the three most popular Unimogs for expeditions:
404 Unimog has been used as an expedition vehicle ever since it’s
introduction. To this day they are used to cross the deserts of
the Sahara, climb the peaks of the Himalayas and to penetrate the
jungles of South and Central America. There is good reason for this.
They are rugged, simple and reliable, and extremely capable. Furthermore,
they are relatively inexpensive and need little modification for
arduous expedition work. A 404 Radio Wagon is basically a “turn-key”
expedition vehicle, ready to provide transport and shelter under
the harshest conditions. Unimog 404s are generally much more capable
than older Land Rovers, Land Cruisers, etc, and just about as comfortable.
The Unimog however have much more room and cargo capacity.
However, 404s do have some drawbacks as expedition vehicles. They
are underpowered and under-geared for expeditions that depend on
extended on-road travel. The lack of power and gearing also means
they do not get good gas mileage, especially when they are being
worked hard. They can also be quite loud and drafty and they have
a tendency to get very hot or cold in extreme temperatures. This
is comparable to older soft-top Land Rovers. A lot people don’t
mind this but it is worth taking into consideration. Finally, parts
can sometimes be hard to find for 404s in remote areas although
they can usually be sourced in more metropolitan areas.
Overall, 404 Unimogs are best suited to short term, leisurely back
country recreation and exploration, where top speed and creature
comforts are not as high a priority as the freedom to explore. Having
said that, the 404 is quite capable tackling the harshest environments
for extended periods of time if the driver is up to it and top speed
is not a priority. Unimog 404s are still a popular Trans-Africa
expedition vehicle and many owners are quite happy with them, especially
ones converted to diesel.
406 and 416 Unimogs make excellent expedition vehicles, especially
with a bit of preparation. Of the two, the 416 makes a better expedition
vehicle due to its greater capacity, more stable wheelbase, higher
top speed and more powerful engine. Of course a 406 can also be
made suitable but here the emphasis is on the 416.
The 416 has the same wheelbase and is approximately the same size
as the 404. However, the 416 is an improvement in almost every way
over the 404. It is even more capable and rugged than the 404. The
416 also has several fundamental differences that make it much more
suitable as an expedition vehicle. First and foremost is the OM
352 diesel engine, which is one of the most trusted engines in the
world. This engine is a heavy-duty unit that is great for expedition
work because of its ruggedness, dependability and relative simplicity.
Plus, since it is the engine of choice in most 3rd world countries,
from Africa to South America, parts and knowledgeable mechanics
are available in even the most remote corners of the world. The
416 also has a heavier duty gearbox and axles. Furthermore, the
axles have optional high-speed gears that improve top speed. With
fast axles and a tuned engine, the 416 is a capable of cruising
speeds fast enough for virtually all expedition requirements.
The cabs in the 416 still somewhat spartan, loud and drafty. However,
they are a vast improvement over the 404 and about the same a Land
Rover. Fortunately there is a lot of room for improvement and the
cab can be made to be relatively quiet and secure, especially the
hard tops. As a result, the 416 can be made into acceptably comfortable
expedition vehicle without too much effort.
many, the 435 series Unimog is the ultimate expedition vehicle.
They are the most comfortable and fastest Unimogs. They have excellent
cargo capacity and despite the larger size, they are incredibly
nimble. Of course when it comes to off-road capability nothing comes
The 435 was engineered by Mercedes to not only endure, but also
excel, in the harshest conditions. It is the epitome of the Unimog
design concept, and as a result, its extraordinary capabilities
allow it to effectively operate in conditions where other vehicles
would struggle or fail completely. Furthermore the 435 is able to
tackle the most extreme terrain and environments with a level of
safety, comfort and control that few if any vehicles can match.
As a result, the 435 is considered as one of the all time greatest
expedition vehicle platforms.
With its locking differentials, extraordinary ground clearance,
approach and departure angles, and articulation, the 435 has no
problem transversing terrain that would stop a Land Rover or Humvee
in its tracks. When it comes to muddy, rutted trails or washed out
roads the Unimog can keep on going well after other vehicles are
high centered or bogged. The 435 comes standard with many features
such as raised a air intake, air compressor, wading breathers, heavy
duty components, etc that have to be retrofitted to most other vehicles.
The weight capacity of the 435 allows for large quantities of food,
water and fuel to be carried providing for extraordinary range and
self-sufficiency. It is possible to outfit 435 with 1500+ mile range
and water and supply capacity to support two people in the desert
for weeks at a time without overloading or compromising the capability
of the truck. Obviously this provides for a level of freedom and
self-sufficiency that few vehicles can match. The 435 Unimog can
be outfitted with all the comforts of a well-equipped RV and can
provide a comfortable living area in even the most extreme conditions.
Although those who choose more basic configurations often scoff
at this level of comfort, it is only possible in a vehicle such
as the 435.
extremely capable, Unimogs are not infallible, and like any vehicle
they can get stuck. They are bigger and heavier than most other
expedition vehicles. This is often an advantage but occasionally
makes tight trails with low overhangs a challenge. This more of
a problem for recreational off-roading than it is for expeditions.
Often people drive Unimogs as if they were smaller and lighter which
can lead to getting stuck. If seriously stuck, a Unimog is much
more difficult to extricate than a vehicle such as a Land Rover,
not only due to its size and weight, but to the fact that the portal
axles allow the Unimog do bog down deeper than conventional axle
vehicles. Winches are recommended for multi-vehicle expeditions
and necessary for solo expeditions, because attempting to push or
pull a stuck Unimog manually, especially the 435, is usually futile.
Because the Unimog is so capable, many drivers don’t get
a chance to learn how to properly drive a Unimog. Even worse, bad
drivers often have a false sense of ability because they mistake
the Unimogs capability with their driving skill. Often this is not
a serious problem because the limits of the Unimog are not reached,
even in many extreme situations. However, like any vehicle, the
Unimog does have limits and it at this stage when driving skills
are most important and when many drivers get hopelessly stuck in
a situation that was probably avoidable. A well-driven Unimog is
capable or truly awesome feats but a poorly driven Unimog can lead
to disaster. It is essential to have a good understanding of the
Unimog principle and what the capabilities of a Unimog are before
setting off on an extended expedition. Driving around on a few trails
is not enough and some sort of tuition is highly recommended.
Finally, it has to be stressed that Unimogs are true off-road vehicles.
They are designed to be simple, rugged and extremely capable in
order to tackle the harshest and most inhospitable terrain. As a
result they do not have the sort of characteristics of modern SUV
or full size trucks that are really only on-road vehicles with some
off-road capabilities. Most Unimogs can be made to easily keep up
with highway traffic, and the cabs can be very comfortable. However,
a Unimog will never be a modern SUV or full sized pick up in terms
of speed and creature comforts. If cruising down the highway at
75+ miles an hour is important or you can’t live without air-con,
power windows, and a smooth and quiet highway ride, then a Unimog
is probably not for you. However, if you are looking for the ultimate
expedition vehicle then there is only the Unimog.
