It can be said that super sports car has a mission to drive the evolution of cars with optimizing the balance between power and environmental performances and pursuing the ultimate driving performance. Nissan has therefore developed the brand new V6 gasoline twin-turbocharged engine for a new generation of super sports cars. To achieve high environmental as well as high dynamic performance, the V6-cylinder layout was selected for its compact size and lightweight while the twin-turbocharged design was aiming for downsizing. All engine parts were designed to achieve high efficiency, as for example, the plasma-sprayed coating of the bore which improves greatly the cooling performance, or the super-heat resistant steel used for the turbocharger, which improves combustion efficiency. Thanks to this technological advance, top-level properties could be attained for sports cars in terms of fuel economy and emissions.

A compact, lightweight compression-ignition engine designed for high fuel economy and low emissions was developed by ISUZU for the GM PNGV vehicle. This engine was the key component in the selected parallel hybrid vehicle powertrain for the 80 mpg fuel economy target. The base hardware was derived from a 1.7 Liter, 4-cylinder engine, and a three-cylinder version was created for the PNGV application. To achieve the required high efficiency, the engine used lightweight components thus minimizing weight and friction. To reduce exhaust emissions, electromechanical actuators were used for EGR, intake throttle, and turbocharger. Through careful application of these devices and combustion development, stringent engine out exhaust emission targets were also met.
