Previewed by the design sketches released at the end of November 2007, the Mitsubishi Concept-RA is powered by a new high-efficiency, low-emissions 2.2-litre 4-cylinder DOHC 16-valve turbo diesel engine with MIVEC continuously variable valve lift and timing control.

The new body structure uses an aluminium space frame made from extruded aluminium sections and die-cast aluminium members, as well as engine hood, bumpers and other outer panels made from high impact-resistance and recyclable plastic resins.

With piezoelectric injector common-rail direct fuel injection that allows a lower compression ratio and with a VD (Variable Diffuser)/VG (Variable Geometry) turbocharger, the diesel unit delivers a maximum output of 150 kW (204 hp) and maximum torque of 420 Nm.

For compliance with U.S. emissions standards (Tier 2 Bin 5 emission regulations), the engine relies on a new catalytic converter system that brings together diesel oxidation catalyst (DOC), NOx trap catalyst (NTC) and diesel particulate filter (DPF) technologies.

Among the technical features are the S-AWC driveline - that includes Active Steering, Active Suspension Control, ACD, AYC, ABS and ASC - and the Twin Clutch SST (Sports Shift Transmission) used in the all-new Lancer Evolution X.

Design

Developed as an "MMC technology showcase", the design uses sport coupe proportions wrapped in dynamic flowing lines that give expression to the car's advanced technological features.

"Muscular wheel arches housing 21-inch wheels give graphic expression to the powerful drive torque and stopping power that Mitsubishi's S-AWC vehicle dynamics control system transmits so effectively to the road surface, while an exposed engine cover highlights the presence of the car's new diesel engine."

The Mitsubishi Concept-RA also sports the inverted-slant nose with trapezoidal grille fascia that marks Mitsubishi Motors new design identity, suitably tweaked to reflect the car's sport coupe attributes.

The red exterior color is counter-pointed by a matte black engine hood that imparts a strongly mechanical flavour.

The interior has been developed to show a fusion of tradition with leading-edge touches.

The cockpit's wrap-round control layout uses minimal visual instrumentation and optimizes the switch and control layout.

This reduces the driver's physical and mental workload, allowing full concentration on driving.

The interior also makes extensive use of natural materials in a design that "delivers a reassuring presence and peace of mind."
