yeah seriously I really want one. This is the route Hummer SHOULD have taken with their new lines of SUVs...

im feeling really shifty about double engines. but looks great nonetheless.

^- Well it is just a crazy concept, but it does showcase sweet technology. Having 2 engines would be pretty sick though...

^^ honestly, i think that the two engines is pretty feasable. i think a bigger problem could come in with that crazy 4 wheel multi-directional steering. there's far less mechanical research done in that field, and far less of a benchmark to base your concept on concerning 4 wheel steering than there is for twin-engined cars.

hmm I dunno. Last time I checked there are a lot more cars with rear wheel steering on the road (Skyline, Prelude, GMC Trucks...) than there are with 2 engines. The Tiger that Tiff tested is the only production car I can think of with 2 engines, and that is really only a trackday car.

I think the bigger problem is not the amount of research, but until recently the use of 2 engines was an obvious tradeoff for power over fuel efficiency. With displacement on demand thats much less of an issue. The other issue I think is additional complexity and packaging problems - why have 2 engines and twice the parts when you can just double the number of cylinders in one engine? In cars (concepts) like this though, the packaging choice of having 16 cylinders split between 2 engines is an obvious plus.

As for 4 wheel steering, I think the big problem there is the threat of mechanical failure. A mechanical failure at speed in a car with such a system of 4 wheel steering as this concept would be a really bad problem...

I think one of my favorite SUVs was the Lamborghini LM002. This was the quickest SUV in its day what with a 455 bhp Countach engine. I had the distinct pleasure of driving alongside one about three years back. The engine sound was to die for (for aforementioned reasons). Lots more character than today's SUVs

However today's uber-SUVs - Cayenne TT, X5 4.8 would be way quicker ....

Absoloutely crazy...what more can i say??? :shock: This is the next craziest car i've ever seen since the TVR speed 12....the turning radius is insane...i have never seen a car that can turn on its axis man....sadly though it will sonsume too much fuel and its way too expensive for nomal use...but surely it overatakes the bowler wildcat in any way...ok i damit this Offroader is good but it still cannot beat the Land rover defender in terms of cost effectiveness...(its a diesel remember?)performance is just one thing...any car can be tuned up to achieve blinding performance(the XC90 si one fine example)

I saw this thing moving on tv and it is really weird to see it go in circles. Apparently they have a tonn of patents from this vehicle, more power to them.

Update: more pics, and some info via ultimatecarpage.com

Show-stopping concepts and extreme expressions of the Chrysler Group brands aren’t new: Dodge had its Tomahawk and Chrysler, the ME Four-Twelve. But when the Jeep Hurricane blew onto the 2005 North American International Auto Show stage, it raised the bar for the Jeep brand.

Hurricane represents the continued success of bold concept vehicles for the brands as a means of demonstrating Chrysler Group’s creative and mechanical expertise. For example, powerful powertrain performance is an understatement considering the Hurricane is not just HEMI-equipped, but HEMI squared. There are two 5.7-liter HEMI engines in the vehicle: one in the front and one in the back. Both engines deliver 335 horsepower and 370 lb-ft of torque – a total of 670 hp and 740 lb-ft of torque.

Can you have responsible excess? To test the theory, we equipped both HEMI engines in the Jeep Hurricane with the Chrysler Group Multi-Displacement System (MDS). Depending on the driver’s needs, the Hurricane can be powered by 4-, 8-, 12- or 16-cylinders. All of that translates into buckets of torque for climbing obstacles other 4x4 vehicles can’t even comprehend. In addition, it has the power and traction to move from 0-60 in less than five seconds. The power is delivered through a central transfer case and split axles with a mechanically controlled four-wheel torque distribution system. The front and rear suspension is short/long arm independent with 20 inches of suspension travel, controlled by coilover shocks with remote reservoirs.

The vehicle has 14.3 inches of ground clearance, and incredible approach/departure angles of 64.0 /86.7 degrees. These are nearly vertical angles – combined with 37-inch tall tires, so the Hurricane won’t meet much that it can’t climb. The Jeep Hurricane is the only vehicle on the auto-show circuit that provides its own turnable feature. The vehicle features a turn radius of absolutely zero, thanks to skid steer capability and toe steer: the ability to turn both front and rear tires inward. In addition, the vehicle features two modes of automated four-wheel steering. The first is traditional with the rear tires turning in the opposite direction of the front to reduce the turning circle. The second mode is an innovation targeted to off-road drivers: the vehicle can turn all four wheels in the same direction for nimble crab steering. This allows the vehicle to move sideways without changing the direction the vehicle is pointing.

The one-piece body is shaped of structural carbon fiber, and forms the chassis that would be offered through a traditional frame. The suspension and powertrain are mounted directly to the body. An aluminum spine runs under the body to both connect the underside and to function as a complete skid plate system. The design is lightweight with high strength, and it boasts functional appearance. Jeep Hurricane is an honest, minimalist approach to its design augmented with the Jeep signature seven-slot grille, two seats and no doors. On the inside, occupants will be surrounded by exposed carbon fiber and polished aluminum with Black Thunder and Tiluminum accents.

these up close shots are pretty cool IMO. get to see some of the detail put into this car - very advanced concept, and highly desirable to me.

With more than 14 inches (36 cm) of ground clearance and 20 inches (51 cm) of suspension travel, the Hurricane is in a class of its own when it comes to off-road capability. As Zetsche said at the 2005 Detroit Auto Show, "To put that into perspective, the clearance is 5 inches higher and the articulation is almost triple that of our most off-road-capable Jeep production vehicle."
And finally, staying at highway speed (65 mph/97 kph or so) can often require less than 20 hp, so one of the HEMIs is turned off while the other runs with only half of its cylinders. All of this cylinder juggling happens without the driver's input -- it's all automatic and barely noticeable.
The Hurricane's power is delivered to its solid split axles through a central transfer case that incorporates a mechanically controlled four-wheel torque-distribution system. In this system, there is a driveshaft for each wheel instead of one central driveshaft. If you've ever seen a powerful vehicle under heavy acceleration, you might have noticed that the frame seems to twist or that one of the tires lifts off the ground. This is due, in part, to the rotation of the driveshaft: The direction of the spin delivers downforce to one side but lifts the other side. The Hurricane's split-axle design applies a downward force on each wheel individually, giving it great traction under acceleration.
3 quick exerpts from the article about the hurricane on howstuffworks.com

This thing is awesome, and quite the incredible technology showcase. I particularly like the center differential with the split driveshafts front and rear. I really imagine some real life applications of this, particularly in offroad suvs and the military, and maybe even powerful pickup trucks and drag racers. I love chrysler's multi displacement system too. If its as seamless as they say it is, thats one hell of a technology and may be the way of the future.
