Today Mitsubishi Motors unveiled a new SUV concept which is set to be revealed at the upcoming Frankfurt Motor show. With an emphasis on environmental concerns, the SUV will be powered by a new high-output, 1.8-liter clean diesel engine, featuring a variable geometry (VG) turbocharger for optimum boost control and a diesel oxidation catalyst (DOC) with diesel particulate filter (DPF) in the exhaust system for compliance with Europe's Euro 5 emission standards.Just like the forthcoming Evo X, the Concept cX features an electronically controlled four-wheel-drive system and fat 225/45R19 tires. Also as in the Evo X, Mitsubishi's Twin Clutch SST (Sport Shift Transmission) transmits the power, offering performance as well as good fuel economy and low emissions. Mitsubishi is also touting the environmental technologies inside the car, including extensive use of what Mitsubishi calls "Green Plastic," made from bamboo and other plant-based resins. The compact cX is short,. At 161.4 inches, it's 6 shorter than a Volkswagen R32 coupe.
