If you think that Nissan's secret weapon at the North American International Auto Show was only the 2016 Nissan TITAN XD then you won't be entirely right. The company actually premiered not only the full-size pickup, but also the new Cummins 5.0L V8 Turbo Diesel engine. Nissan has just released a short film in which it literally shows-off with the unique features of the engine. The video is a detailed animation, displaying what the unit consists of and how it actually works.

A Cummins M²™ Two-Stage Turbocharger, which is featured in the engine, is configured to work effortlessly at both low and high engine speeds. The series sequential turbocharging system uses two differently sized turbochargers and effectively delivers a small turbocharger for low air flow requirements and a large turbo for high air flow.

The small one offers the benefit of better transient response, because of low inertia. On the other hand, the large turbo maintains power at higher engine speeds. This also contributes to elimination of the turbo lag, meaning that it provides a continuous delivery of peak torque through the RPM range.

And if you wonder about the control of the air flow between the two turbochargers, well, it is possible due to the new M² system. It works by utilizing a patented rotary valve to open ports that perform the bypass or waste-gate functionality and provide exhaust after-treatment thermal management.

And if you ask me: this is the twin-turbo of the 21st century and I'll definitely take one.
