About Model
We start with engine. The Boxer air-cooled engine serves as the core of the car, an engine used
in several later generations of classic cars and lasted 65 years in the Beetle, a saga that came to
an end when the last Beetle, number 21,529,464, rolled off the production line in Puebla, Mexico,
on July 30, 2003. Initially the Type82 used a 985cc engine, later upgraded to 1131cc, then gradu-
ally increased displacement, and in the Porsche 356 used a 1488cc engine, doubling the
horsepower from the very beginning. The cylinders of the horizontally opposed engine are distrib-
uted on both sides, a 130 motor in the right cylinder position, and another 130 motor reserved for
the left side, which can output twice as much power when applied to the VW T1 or Porsche356
platform. The engine crankshaft flywheel is connected by a belt to drive the generator and the
cooling fan as well. The semi-circular fan fairing is a major feature, in which the airflow is distribut-
ed to the cylinders on both sides. All is faithfully restored on the model, meaning you can observe
the blades rotating through the fan intake when the motor is running. The Kübelwagen has 4
forward gears and the maximum speed of each gear respectively goes as 1st gear 18.4km/h; 2nd
gear 32.4km/h; 3rd gear 54.2km/h; 4th gear 83.6km/h. The corresponding red line of gearshift tips
is available on the dashboard. On the model, we designed a 2-speed shift to simulate the speed
of the 1st and 3rd gears of the real car. The power crosses over from the top of the rear axle
differential and then returns to the rear axle. The model shares the same structure as the real
engine, with the benefit of compactness, making it easy to switch between 4WD and RWD modes.
This shift function is perfectly reproduced on the model to provide more driving pleasure when
driving off-road.
Now let's move to chassis. The popular portal axle in today's climbing car market has been in
mass production for barrel cars as much as 82 years ago, from which wheelside reducer reduction
ratio of 15:21 has learned a lot, making the barrel car chassis minimum ground clearance of
310mm, dwarfing all modern off-road cars on the market today. On the real car, the front and rear
wheel speeds are balanced by increasing the front axle differential gear ratio while on the model
we set the door axle reduction ratio to 1:1 for common front and rear axle differentials.
Solid load-bearing chassis with stamped central ridge tube chassis and body bears high torsional
resistance. The central drive shaft and electrical wiring are hidden in the ridge tube. The one piece
injection model features the texture of metal stamping with plastic as location and size of each
reinforcement are restored according to the actual car. The front and rear wheels adopt
torsion-bar-sprung independent suspension, allowing long travel capability with little space
occupation. We use torsion springs instead of torsion bar springs to present the front and rear
suspension, easy to disassemble and change tuning.
With regards to tires, the model adopts the same 5.25 x 16 off-road tires as the barrel car. The
simulated wheels need to be fixed with 5 screws like the real car, and the spare tire in the front is
readily accessible after opening the hood. Here you can also charge the battery at your conve-
nience with battery properly stored in the actual car fuel tank.
Can the doors be opened? Let's try the door handle. Pull outward- the door can be opened with
the built-in spring lock push, when closed you can hear the spring lock crisp "kata" sound. Door
