Here are some of the technologies that are extending the life of the internal combustion engine by making it more efficient.
Displacement on demand: Shuts down unneeded cylinders once a vehicle reaches highway speeds.
Variable compression ratio: Enables an engine to run more efficiently based on speed and load. Nissan is the only manufacturer to offer a production engine with this technology.
High-pressure direct injection: Atomizes fuel into extremely fine particles to improve combustion, lower emissions and improve performance.
