The system uses a sequential arrangement, with a smaller turbocharger optimized for low airflow and a larger compressor geared for higher exhaust flow.
With a lower inertia, the smaller unit can spool up faster and significantly reduce perceived lag time. The larger compressor, meanwhile, helps maximize power in the higher rpm range.
The M² system from Cummins Turbo Technologies serves as the airflow control between both turbochargers. A patented rotary valve directs exhaust gasses to the compressors or bypass ports.
“We are excited to have Cummins as a partner to launch the new TITAN XD,” said Nissan Titan chief product specialist Rich Miller. “The Indiana-made Cummins 5.0L V8 is a perfect fit for our truck that was designed in California, engineered in Detroit, and will be assembled in Mississippi.”
The new Titan will arrive first in its XD trim, featuring the Cummins diesel engine, ahead of the gasoline-powered variants.
