Original name: 三菱 コンセプト RA

MITSUBISHI Concept-RA

Illustrating the fact that thrilling performance and environmental responsibility need not be mutually exclusive concepts, MITSUBISHI Concept-RA features the S-AWC vehicle dynamics control system and the Twin Clutch SST automated manual transmission used in the Lancer Evolution. The car is powered by a new high-output, high-efficiency clean diesel engine and uses an aluminum space frame body to reduce weight.

(1) Design

Developed as a "MMC technology showcase", the design uses stylish sport coupe proportions wrapped in dynamic flowing lines that give powerful and eloquent 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 powerful and clean diesel engine. 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.

MITSUBISHI Concept-RA uses red exterior coloring that graphically accentuates the beauty of its fluid body lines, counter-pointed by a matte black engine hood that imparts a strongly mechanical flavor.

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 fine-quality natural materials in a design that delivers a reassuring presence and peace of mind.

(2) Technologies

The MITSUBISHI Concept-RA's S-AWC driveline adds Active Steering and Active Damper to the ACD*1, AYC*2, Sport ABS*3 and ASC*4 components that make up the system used on Lancer Evolution. S-AWC integrally manages these systems to realize advanced levels of control over drive torque and braking at each wheel, thereby raising traction, cornering and vehicle stability levels. All this adds up to intuitive, on-demand vehicle behavior that faithfully reflects driver intent under all driving conditions, from everyday use to emergency avoidance situations.

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 aluminum space frame made from extruded aluminum sections and die-cast aluminum members, as well as engine hood, fenders and other outer panels made from high impact-resistance and easily recyclable plastic resin.
