When the covers were pulled off the 2016 Nissan Titan XD full-size pickup at the 2015 North American International Auto Show earlier this month, it was really two debuts in one with the all-new Cummins 5.0L V-8 Turbo Diesel engine being shown for the first time too.

The Cummins 5.0L V8 Turbo Diesel in the upcoming 2016 Nissan Titan XD features a Cummins M² Two-Stage Turbocharger, which is configured to work well at both low and high engine speeds. The series sequential turbocharging system, involving two differently sized turbochargers, effectively provides a small turbocharger for low air flow requirements and a large turbo for high air flow. The small turbo provides the advantage of good transient response due to its low inertia and the large turbo maintains power at higher engine speeds. This helps eliminate turbo lag, providing a continuous delivery of peak torque through the RPM range, according to the company.

In order to control the air flow between the two turbochargers, the new M² system from Cummins Turbo Technologies uses a rotary valve to open ports that perform the bypass or waste-gate functionality and provide exhaust after-treatment thermal management, according to the company.

“We are excited to have Cummins as a partner to launch the new Titan XD. 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,” said Rich Miller, chief product specialist, Titan, Nissan North America, Inc. “The 2016 Titan reflects the passion that both Nissan and Cummins employees have toward their heritage as truck people. We collectively know what we would want in our own truck and pulled together all of those traits into one unbeatable package that we are thrilled to finally show the world.”

    Interesting, but no sale. Never have cared for any "V" diesel in any way, shape, or form. And with the emissions stuff on them now, no way. They can put all the lipstick on a pig that they want, but it is still a pig. Gasoline, NG, or propane is the only thing I will consider.
