Clean Diesel and Twin Clutch on Mitsubishi Concept-RA
Mitsubishi Concept-RA
Mitsubishi will show the Concept-RA at the 2008 North American International Auto Show (the Detroit Motor Show). Mitsubishi Concept-RA is a sport coupe with a heightened sensitivity for the environment thanks to a clean, efficient drivetrain. The concept is powered by a new high-output, high-efficiency clean diesel engine and Twin Clutch SST automated manual transmission, driving Mitsubishi Motors' advanced S-AWC vehicle dynamics control system.
Mitsubishi Concept-RA is powered by a new high-efficiency and low-emission 2.2-liter 4-cylinder DOHC 16-valve turbo-diesel engine with MIVEC, which switches between low and high-speed cam profiles to drive intake valves, and piezoelectric injector common-rail direct fuel injection, allowing the use of a lower compression ratio. And with its VD/VG (Variable Diffuser / Variable Geometry) turbocharger producing optimum boost characteristics at all times, the clean diesel unit delivers a maximum output of 150 kW (204 PS) and maximum torque of 420 Nm (42.8 kg-m). For compliance with Tier 2 Bin 5 emission regulations in the United States, the clean power unit uses a new catalytic converter system that brings together diesel oxidation catalyst (DOC), NOx trap catalyst (NTC) and diesel particulate filter (DPF) technologies.
For improved crashworthiness and to reduce weight MITSUBISHI Concept-RA features a new body structure using an aluminium space frame made from extruded aluminium sections and die-cast aluminium members, as well as engine hood, fenders and other outer panels made from high impact-resistance and easily recyclable plastic resin.
