This Day:

Can chase its tail...
Daimler-Chrysler recently unveiled its top-of-the-line Jeep prototype at Detroit Car Show. Named Jeep Hurricane, it is truly a concept car, with twin HEMI V8 engines, each with 335hp (horse power), and 370lb-ft of torque. The engines can operate independently of each other, and the jeep switches off cylinders when they are not required (cruising on a highway, for example). The jeep has a 14 inches (36 cm) of ground clearance and 20 inches (51 cm) of suspension travel, thus giving the rider a great off-road experience.

The twin engines ensure that the jeep can ride up slopes of 64º, and descend down slopes at 86.7º! The engines provide powers to the wheels through four independent driveshafts (unlike one driveshaft in most vehicles), each of which can operate independently of each other, and at different orientations. This allows the jeep to have a turning radius of zero, that is, the jeep can rotate at the same place. Four independent shafts also leads to better traction and stability. The Hurricane can also crab-steer, that is, move to the side without changing the direction it faces.

There is only room for two passengers in the jeep. The body/chassis is made of carbon-fiber, and the engines/suspension are fused into the body. No doors/roof, and not much shock absorption; this leads to some rough riding!

How much does this look like the Warthog from Halo?

The twin engine set-up isn't entirely new. Can't remember where, but I've see it before.

More recently, Hyundai have used twin engines, but arranged so that one engine power each rear wheel.

So, two 1.3 litre engines are more productive than a single engine twice the size...

I have seen twin engines before.. but the interesting thing was the four independent shafts, which can rotate in both directions. I dont think anyone had that before? Also, really powerful engines, but that is a difference of a degree, not of a kind.

OH, yeah! The warthog from Halo :-D... lets mount the gunner, shall we?!

Seems overly complicated to me.

What happens if one of the drive shafts breaks?

Do you spin round in a circle?

I'm hoping not...

Seems complicated.. but I think the on-board computer (must be there) handles all that. The driver just selects the mode he wants the shafts to be in (normal, crab-steer, rotate, etc.). If a shaft breaks... hey this is just a prototype!

I'm guessing that if one of drive shafts broke, then you'd function as normal -- with the obvious imbalance of torque ratio on either side of the car.

The only things you wouldn't be able to do is all of the weird spinning on a six-pence and the crab-fashion side-ways motion thing...

True. One thing Ilike about this jeep is its symmetry. I can almost imagine the driver sitting in a turnable turret at the center of the car, with full flexibility of wherever to go. Perhaps one should add spherical wheels instead, and then we would have a true concept car!!

And while we are at it, why not add hovercraft capabilities as well?!

Lucretia, I thought you were buying a Subaru Impreza?

Hi Lucretia,
thanks for the comment! About the Jeep thingie, Wayne (Smallman) is interested in one (look at all his comments), and he would buy it for you, but alas! It is still a prototype :-).

People who would buy this jeep wont do it for mileage, now will they? But it is a great jeep.. and since it can adjust its power output depending upon requirement, the mileage could be optimal.
