Mitsubishi premieres the new Concept-RA to the world at the 2008 North American International Auto Show (NAIAS or the Detroit Motor Show)[1].

The Concept-RA fuses together three elements of Mitsubishi’s core DNA - a passion for dynamic driving, stunning design and a heightened sensitivity for the environment - thanks to clean, efficient high performance diesel power.

This coupe concept features the S-AWC[2] vehicle dynamics control system driveline and the Twin Clutch SST used in the Lancer Evolution X[3], is powered by a new high-output, high-efficiency clean diesel engine.

The vehicle’s S-AWC driveline adds Active Steering and Active Suspension control to the ACD[4], AYC[5], Sport ABS[6] and ASC[7] component systems that comprise the system used on Lancer Evolution X.  S-AWC integrally manages all of these systems to realize advanced levels of control over drive torque and braking, thereby upgrading traction, cornering and vehicle stability.  All this adds up to intuitive, on-demand vehicle behaviour that faithfully reflects driver intent under all driving conditions, from everyday use to emergency avoidance situations.

Power comes from a new high-efficiency, low-emission 2.2-litre 4-cylinder DOHC 16-valve turbo diesel engine with MIVEC[8] - continuously variable valve lift and timing control.  With piezoelectric injector common-rail direct fuel injection that allows a lower compression ratio and with a Variable Diffuser / Variable Geometry turbocharger, 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 U.S. emissions standards, the engine utilises a new catalytic converter system that brings together diesel oxidation catalyst (DOC), NOx trap catalyst (NTC) and diesel particulate filter (DPF) technologies. The new diesel engine will deliver exciting driving manners with a high degree of fuel efficiency.

For improved crashworthiness and to reduce vehicle weight, the 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 bonnet, bumpers and other outer panels made from high impact-resistant and easily recyclable plastic resin.
