Athletic pure coupe

Green is still the word in the automotive world, and Mitsubishi is bringing its own view on the topic to the 2008 North American International Auto Show. The sporty coupe combines cutting edge drivetrain technologies with the latest clean diesel design. The Mitsubishi Concept-RA packs one of the latest gadgets from Japan - already featured on the Mitsubishi Lancer Evolution, namely the Super-All Wheel Control system which consists of Active Center Differential, Active Yaw Control, Sport ABS and Active Stability Control component systems.

But what the Lancer Evo does not do is partner the S-AWC with a 2.2 liter 4-cylinder DOHC 16-valve diesel engine. We knew that Mitsubishi was working on a new diesel for Europe, but also the US is warming up to diesel after the German diesel invasion. This diesel produces 201 hp with 310 ft-lbs of torque and meets US emissions standards.

In an attempt to further improve performance, fuel economy and safety, the Concept-RA is built around an aluminium space frame while the hood, fenders and outer panels are molded from impact.resistant and recyclable plastic resin.

Press Release

The MITSUBISHI Concept-RA continues a long tradition of sporty coupe concepts dating back to the 1972 debut of the Galant GTO R73-X show car, which showcased high revving, high output (200 hp) DOHC engine technology. Combining cutting edge drivetrain technologies with the latest clean diesel engine design, MITSUBISHI Concept-RA demonstrates that a thrilling performance machine and a sense of environmental responsibility need not be mutually exclusive concepts. The Concept-RA features a "next generation" Super-All Wheel Control (S-AWC) system that is comprised of Active Center Differential, Active Yaw Control, Sport ABS and Active Stability Control component systems, as equipped on the very capable Lancer Evolution. For Concept-RA, this vehicle-dynamics-enhancing, all-wheel-drive system is upgraded to include Active Steering and Active Damping Control elements to further improve driver control, as well as vehicle handling and stability. S-AWC integrally manages all of these systems to realize advanced levels of control over drive torque and braking, thereby improving traction, cornering and vehicle stability. This complex system of electronic traction and driveline control help create 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 output, low-emissions 2.2-liter 4-cylinder DOHC 16-valve turbo diesel engine. This engine features a MIVEC(1) valvetrain that offers continuously variable valve timing control as well as low and high speed camshaft profiles. The new diesel is equipped with piezoelectric injector common-rail direct fuel injection that allows a lower compression ratio and a VD (Variable Diffuser)/VG (Variable Geometry) turbocharger. The 2.2 liter clean diesel unit delivers a maximum output of 201 hp (150 kW) and maximum torque of 310 ft. lbs (42.8 kg-m). In an effort to comply with U.S. emissions standards (Tier 2 Bin 5 emission regulations), the diesel relies on a new catalytic converter system that utilizes diesel oxidation catalyst (DOC), NOx trap catalyst (NTC) and diesel particulate filter (DPF) technologies. When mated to a Twin Clutch-SST gearbox, the torque-rich diesel engine will help deliver sporty driving manners with a high degree of fuel efficiency.

MITSUBISHI Concept-RA makes extensive use of lightweight materials in its construction to help reduce vehicle mass for improved performance, fuel economy and safety. The athletic coupe features a new body structure that utilizes an aluminum space frame made from extruded aluminum sections and die-cast aluminum components, as well as the hood, fenders and other outer panels molded from impact-resistant and easily recyclable plastic resin.
