2015 Nissan Titan XD: Turbo Diesel Comes to Another Light-duty Pickup Truck

Last week Nissan introduced the world to their new Titan XD pickup.  And as an added bonus, they unveiled a new 5.0 liter turbo diesel engine for the model as well.

This means only Ram and Nissan are the only two manufacturers to offer turbo diesels in their light duty pickup category.  We know that the 3.0 liter 1500 EcoDiesel in the Ram is going gangbusters.

This new power plant generated 310 horsepower and 555 lb/ft of torque.  So you can probably pull 2 Space Shuttles with it, one-upping the Toyota Tundra.

Nissan and Cummins have much more to say about the engine:

The next-generation Nissan TITAN expands Cummins presence in the North American pickup market from heavy-duty trucks to now extending to serve the light-duty segment.  The new TITAN XD engine features over 70 percent parts commonality with the commercial variant of the Cummins ISV5.0 engine family – which includes vehicles with 30,000-pound gross vehicle weight ratings. The 5.0L V8 Turbo Diesel stands alone between the smaller and larger diesel offerings in the pickup market.


“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.  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.”


The engine isn’t just a turbo diesel, it’s a kind of twin-turbo.  The rail-injected power plant has a serial-sequential turbocharger that provides power at the low and high end.  From the article:

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.


The Titan XD will be in showrooms later in 2015.  We will keep you in the loop on sales figures.
