Howstuffworks.com – “How the Jeep Hurricane Works”

Howstuffworks.com (a great site to kill time at when bored) has an awesome write-up on the Jeep Hurricane concept, a beast that boasts twin Hemi V8s (producing a total of 670 horsepower and 740 ft/lbs of torque), a driveshaft for each wheel and four-wheel independent steering.

My favorite highlight:

Fuel efficiency isn’t always the first thing on a Jeep enthusiast’s mind, but cruising along with two HEMIs roaring might seem wasteful. In keeping with the concept of combining responsibility with excess, Chrysler used its multi-displacement system in the Hurricane. This system allows half of the cylinders in an engine to be deactivated when the vehicle doesn’t need as much power. When you’re pushing your way through thick mud or climbing a rock face at a 50-degree angle, all 16 cylinders (eight per engine) are cranking out power. If you’re charging along a trail, it might only need 12 cylinders, so four cylinders in one of the engines are deactivated. Driving around in the suburbs doesn’t demand a huge amount of horsepower, so another four cylinders are deactivated, leaving just eight cylinders running. 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.
