Cummins, Nissan Collaborate on 28 MPG Diesel Pickup

Cummins, a major manufacturer of diesel engines, Nissan and the U.S. Department of Energy are joining forces to bring new fuel-efficiency technology to the half-ton pickup truck market, according to

The group is working on a 220-horespower, turbocharged 2.8-liter inline-four-cylinder diesel engine that is expected to achieve 28 mpg in the combined EPA cycle. That figure could mean that a full-size pickup would be able to achieve 30 mpg on the highway — better than any truck available today.

On top of the fuel-efficiency target, the engine would also be designed to emit low emissions to meet California’s super-ultra-low-emissions-vehicle (SULEV) standard. The Toyota Prius and Honda Insight currently meet this standard.

Cummins and Nissan have already tested a prototype version of the engine in a Nissan Titan pickup. The project is scheduled to be completed by fall 2014, when the next-generation Titan is expected to debut.

And some redneck idiot will remove the cat and muffler and put stacks on it because he thinks it sounds cool. Never mind the people outside who have to hear it. This is why people think diesels are noisy and smelly and want to ban them!

You don't need a diesel to make a car really loud.
The important thing is, how much can it tow/haul?

This alone would make me buy a Nissan Titan I would absolutely love this engine combination with a relatively light duty truck. Great combination and perfect for those of us who don't need 6-7 liters of displacement.


i agree. this will get better mileage than any compact/midsize and still have really good towing capability. sign me up!


Midsize pickup with all kindsa torque, good fuel economy, and diesel reliability. It's about time!
