A model of a Concept Jeep, with advanced steering.
About this creation

This is a complex model of Jeep's coolest concept vehicle ever, one that few have attempted to make out of Technic. (I saw about four or so other models) It is a super cool vehicle because it can turn on the spot, do four-wheel steering, and crab steering. Mine was intended to replicate the many steering modes.
Aesthetics:
The model I think looks pretty cool, with dual V8s, rugged Jeep looks, and a cool enough color scheme. It wasn't perfect, though, and the bumper things had to be pushed out too far to allow the steering to work.















Suspension: The vehicle had full double, wait no TRIPLE wishbone independent suspension (The third wishbone was added later to increase stability. All wheels had portal axles, as well. (I am not sure whether the real one had these, but in the images I looked at, the universal joints seemed to be a bit above the centers of the wheels) Each wheel had one hard and one soft shock.





Drive:
2XL motors drove one differential. Because of the interesting way this vehicle works, with all the steering, I only really needed one differential between the left and right drivetrains. There was also a switch that reversed two wheels on one side to allow for skid steering in the on-the-spot mode. Each wheel also had it's own worm gear reduction. It also drive two V8 piston engines, just like the real vehicle. Sadly, the drivetrain turned out so inefficient that it could barely drive. No allusions of off-road prowess here.







Steering:
Each axle was normally steered by one M-motor using clutch gear. These gears allowed the vehicle to synchronize itself when switching steering modes. A PF switch allowed me to invert or turn off the rear M-motor, which allowed me to switch between crab, 4 wheel, and front wheel steering.
A L-motor also drove 13L racks using new worm gears which pushed the front and rear steering racks forward, disconnecting them from the pinion gear and bringing the fronts of the wheels inward. If you then switched to skid-steer mode, the vehicle would in theory turn on the spot. Sadly, the vehicle was way too weak, and the wheels didn't turn as far inward as they needed to, so it only worked in theory.











Overall, it was a fun model, but performance was terrible, which was sad for a vehicle that looks so cool.

Quoting Nils O. That's awesome! The Hurricane is one of my all time favourite concept cars! Your Technic version has all it needs. Great job! :-))
Thanks!

Quoting Nathanael Kuipers Nice work! I did an attempt many years ago based on a similar principle. It's interesting to read that you have similar difficulties with the performance today as I had back then, even though many new parts have become available.
It is unfortunate. I did see a few other Hurricanes, though, and some of them seemed to work in the videos.

Quoting Technic Man 5/5. This model is very interesting, particularly the on spot rotation/steering mode. The idea of pushing the rack and pinion frontwards is surely very good. And that makes me think that if you pushed it backwards it could have a greater angle and so, not only work in theory, but also work in reality. That would mean that you'd have to push the differential upwards (even more than it already is) to have room for the rack. Just a thought :)
Interesting. I have been considering making another more performance-based one that would be simpler and less realistic. That could work. (The sliding rack idea came from Nathanial Kuiper's model)
