Cummins to Produce High-Performance, Light-Duty Diesel Engines for Automaker
26 July 2006

Cummins Inc. has reached agreement with a major automotive manufacturer serving the North American market to produce and market a light-duty, diesel-powered engine. For competitive reasons, Cummins’ original equipment manufacturer partner in the venture has asked to remain confidential.
As part of the agreement, Cummins will develop and manufacture a family of high-performance, light-duty diesel engines for a variety of automotive applications in vehicles below 8,500 pounds gross vehicle weight, including standard pickup trucks and sport utility vehicles. Certain bus, marine and industrial applications also will be served by this engine family.
The first vehicles with this engine are expected to be ready for market by the end of the decade. Cummins anticipates that this diesel engine will provide an average of 30% fuel savings, depending on the drive cycle, over gasoline-powered engines for comparable vehicles.
The concept for this product is the result of a nine-year partnership between Cummins and the US Department of Energy that has been developing an engine family with a 4.2-liter V6 and a 5.6-liter diesel V8 that will meet EPA Tier II and CARB LEV II emissions standards.

In test vehicles, development versions of the 4.2-liter V6 have delivered combined cycle fuel economy of 22.1 mpg US, while development versions of the 5.6-liter V8 delivered 21.7 mpg US.
Earlier work on the new engine family used precise control of the air handling system and combustion to reduce engine-out emissions, followed by aftertreatment with a four-way catalyst system, including NOx Adsorber and Particulate Filter.
This agreement gives the driving public an even greater opportunity to experience the benefits of a new class of vehicles powered by a high-performance, fuel-efficient, clean diesel engine made by Cummins. This line of diesel engines also will fuel the growth of an exciting new market in which Cummins does not currently participate.
—Tim Solso, Cummins Chairman and CEO
Cummins currently provides on-road engines for the Dodge RAM pickup and a variety of medium- and heavy-duty vehicles, as well as off-highway and marine engines.

My understanding is the V6 will go in Dodge Ram 1500 and possibly Dakotas, Durangos, and hopefully in the larger cars. My dad was in Chicago and was told this by someone in the DC group at a display on Navy Pier.
As for Rob's comment about Cummins and Dodge: Dr. Z isn't stupid. He knows Dodge Diesel and Cummins are synonymous and isn't going to ruin a good market plan. With Ford and International Truck and Engines (ITE), the problem isn't the engine manufacturer, it's FORD. ITE's original design for the 6.0 PowerStroke was a good design, but Ford wanted to cut costs, so corners were cut, at Ford's demand. That's why the first 6.0 PS motor had problems. If I were ITE, I would've said "no deal."
My dad wants one for the farm. Says he doesn't need the B5.9, as he has grain trucks to do his heavy hauling. He just needs a pickup with good fuel economy to make small "pickups" and trips to town from the field.
As for using the B3.9, that would work in the Ram, but it wouldn't exactly fit in a car, height-wise, if you want to keep things streamlined. This is one of the reasons HMMWV motors are V-motors. I-6s are too tall.

i think intelligent individuals need to work some sort of petitions not only to the industries but polititians to to their heads out the sand and start dealing with our environmental problems before it is a last minute problem.
and as to the exhuast output of cars many houses through the coal power plants that supply their electicity pollute far more than cars

The Cummins V8 will go into the Dodge Ram 1500, and the V6 will go into the Durango and Dakota. They will both be manufactured at Cummins main plant #1 in Columbus, IN.

I'm hoping they put the 4.2 Cummins in the Dakota. If they do, I'll be buying my second Dakota sometime in the next 3-4 years.

Anything to the rumor Cummins will build a new plant for this on DCX Chrysler land in Kokomo, Indiana, near the 4 existing Chrysler foundry and transmission plants there?
