Cummins 5.0L V8 Turbo Diesel years in the making
Nissan and Cummins have worked together on optimizing a calibration and specific hardware for the Cummins 5.0L V8 Turbo Diesel since the partnership began in 2007.
The engine has been undergoing rigorous validation work since then, with countless hot and cold test cell hours and over a million grueling test miles to prepare it for production later in 2015 for use in the 2016 Nissan Titan XDs.
“The next-generation Nissan Titan XD is a truck that we are proud to have our Cummins engine in and logo on,” said Jeff Caldwell, Cummins General Manager – Global Pickup Business.
“Pickup truck owners have very specific needs and capability has always ranked high on the list and with increasing fuel prices, efficiency is a close second,” says Caldwell. “The new Titan XD is capable of meeting both of those needs at once, as opposed to only being able to have great fuel economy or great performance. Light-duty pickup owners should not have to sacrifice fuel economy when they want to put their truck to work.”
About the Cummins 5.0L V8 Turbo Diesel
The 5.0L V8 Turbo Diesel brings together a compacted graphite iron (CGI) cylinder block, forged steel crankshaft, high-strength aluminum alloy heads, and composite valve covers to offer maximum durability in a lightweight package.
These features, along with dual overhead camshafts, also contribute to the excellent noise, vibration and harshness (NVH) characteristics achieved by the 5.0L V8 turbo diesel.
The Cummins M²™ Two-Stage Turbocharger 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 eliminates turbo lag, providing a continuous delivery of peak torque through the RPM range.
In order to control the air flow between the two turbo chargers, the new M² system from Cummins Turbo Technologies uses a patented rotary valve to open ports that perform the bypass or waste-gate functionality and provide exhaust after-treatment thermal management.
High injection pressures from the latest Bosch® High Pressure Common Rail (HPCR) fuel system and piezo fuel injectors provide precise fuel control for optimized in-cylinder combustion, leading to better fuel efficiency and reduced emissions.
With multiple injection events driven by integrated electronic controls, the HPCR fuel system, along with Cummins M2™ Two-Stage Turbocharger, contributes to a very impressive peak torque of 555 lb-ft and 310 horsepower.
In cold weather, the advanced ceramic glow plug system significantly reduces start time and electrical current draw, reducing vehicle charging system requirements. The ceramic glow plugs are designed to last the life of the engine, with no maintenance.
A two-stage fuel filter system for the 5.0L V8 Turbo Diesel features the latest NanoNet™ media from Cummins Filtration, to ensure that the HPCR fuel system is fully protected against fuel contamination.
NanoNet’s unique construction provides lower fuel-flow restriction, and traps greater than 99 percent of all particles as small as 4 microns.

Proven air handling and emissions control technology draws upon Cummins extensive emissions technology expertise. Cummins M2™ Two-Stage Turbocharger, cooled Exhaust Gas Recirculation (EGR) and Cummins Emission Solutions Aftertreatment System, featuring a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR), result in near-zero oxides of nitrogen (NOx) and particulate matter (PM) emissions while delivering better performance and fuel economy.
“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”
