Mitsubishi Motors North America of Detroit released the Concept-RA, a coupe that matches high performance with environmental sensitivity. The Concept-RA is powered by a high-output, low-emissions 2.2-l, 4-cylinder, 16-valve turbo diesel engine. To comply with U.S. emissions standards, the diesel relies on a new catalytic converter system that utilizes diesel oxidation catalyst, NOx trap catalyst and diesel particulate filter technologies.
The Concept-RA also makes use of lightweight materials in construction to help reduce vehicle mass for improved performance, fuel economy and safety. The coupe features a new body structure that utilizes an aluminum space frame made from extruded aluminum sections and die-cast aluminum components. The hood, fenders and other outer panels are molded from impact-resistant and easily recycleable plastic resin.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
