Not sure about street legality, but here's some info from Jeep's site:
Hurricane represents the continued success of bold concept vehicles for the brands as a means of demonstrating Chrysler Group LLC'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 LLC 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 design is lightweight with high strength, and it boasts a 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.
