Driveline: Front-engine, full-time 4WD Engine: 6 Cyl 3200 cc, Turbo diesel (DI) Transmission: 5/6 speed manual + 2 speed transfer box Brakes: Four-wheel disc, four-wheel/four channel ABS, dual piston calipers with Dynamic Rear Proportioning Suspension Front: Independent: Unequal Arms with torsion bars; Monotube gas shocks; Stabilizer bar Rear: Independent: Unequal Arms with variable-rate coil spring; Monotube shocks, Stabilizer bar

PROJECTED DIMENSIONS Length: 4400 mm Width: 1800 mm Height: 1675 mm Wheel Base: 2700 mm Ground Clearance: 220 mm Track F/R: 1500 mm Weight: 1400 Kg (kerb)

The innovative unit body is based on fully welded perimeter/space frame chassis fabricated from Hydroformed tubular steel elements (formed with water under high pressure, which allows steel to retain more of its strength through the manufacturing process) and multi-axial roll formed and/or dieless NC forming process formed metal panels. This technique makes expensive dies redundant. The designer's aim is to save materials and money through part elimination and simplified assembly processes by part integration.

The project targets a 20 percent reduction in dry weight to comparable sized SUV, yet with an increase of torsional rigidity as well as bending rigidity.

Hydroformed tubular elements promise reduction in tooling costs, dimensional precision, design-to-production timesaving and low waste / scrap rates.

Stiffness, weight reduction, increased repeatability and improved tolerances are all key advantages to implementing hydroforming into the production process.

Further weight reduction is possible with the use of Hydroformed tubular aluminum alloy/ extruded aluminum for the space frame chassis skinned with alloy and/or composite panels. Such a product would show a projected 40 percent weight reduction in the body-in-white stage.

OPTIONAL:

DRIVE TRAIN: Parallel hybrid (Diesel-Electric) The Parallel Hybrid power train gives the SUV a) more mileage with the use of the stop/start function, b)torque-smoothing for improved power train efficiency, and c) regenerative braking, which turns the motor into a generator to capture energy as the vehicle decelerates. A 15 percent better fuel mileage is targeted with no reduction in performance and/or towing capacity.

ELECTRO-MECHANICAL rear wheel steer system That turns the rear wheel to produce four-wheel steering can also be incorporated. The rear wheels turn as a percentage of the front wheels up to a maximum 9-degree angle. The angle is based on vehicle speed and steering wheel turn. This would enhance high speed handling in Highway mode and endeavor superior maneuverability in tight cross-country situations.
