Dodge may offer more Cummins diesels in light duty trucks

[jetsetter]

Dodge is likely to get a pair of new high-performance turbocharged diesel engines from its longtime diesel engine supplier, Cummins Inc.

The engines, a 4.2-liter V-6 and a 5.6-liter V-8, are scheduled for production in 2010 and probably will first appear in the light-duty 1500 version of the Ram pickup and the Durango SUV.

Chrysler group officials would not comment on future product plans.

Cummins said in a statement that the company has signed a deal to supply "a family of high-performance, light-duty diesel engines for a variety of automotive applications in vehicles below 8,500 pounds gross vehicle weight." Spokesman Mark Land would not identify the manufacturer or provide any technical details of the engines.

DOE partnership
The Cummins engines were developed in partnership with the U.S. Department of Energy. On the agency's Web site, Cummins documents outline the preliminary specifications for the new engines. Both have overhead cams, four valves per cylinder, aluminum heads and thin-walled cast-iron blocks.

Only a few full-line automakers are known to have a need for diesels: Toyota, Nissan and the Chrysler group.

"It's not Nissan, and it's not Toyota. We're pretty confident that it is Chrysler," said Casey Selecman, a powertrain analyst with CSM Worldwide in suburban Detroit.

If Dodge is the automaker that signed with Cummins, it would be continuing a relationship that started almost 20 years ago. Cummins has been supplying diesel engines for Dodge's Ram trucks since 1989. And the agreement would replace the current contract, signed in 2003, which expires in 2010.

Cummins, of Columbus, Ind., makes the 325-hp, 5.9-liter, inline-six-cylinder engine used in the heavy-duty 2500 and 3500 versions of the Ram. That truck is getting an all-new version of the engine in January.
Powerful competition
If Dodge does use the new diesel in the Ram 1500, it would give the Chrysler group a vehicle to compete with a new diesel version of Ford's F-150, which is expected before the end of the decade. Ford is planning to use a 4.4-liter version of a Land Rover diesel in the F-150.

Diesel plans are less clear for Toyota and Nissan.

Toyota is widely expected to get diesels from its Hino truck affiliate. But Toyota has not announced any time frame. Nissan has been negotiating with International Truck and Engine Corp., Ford's longtime supplier. Nissan spokesman Fred Standish in Nashville would not comment on potential diesel suppliers.

Land said Cummins is looking for a plant to build the engines. He said the company could buy an existing plant from an automaker or supplier. About 600 jobs will be created. Land said Indiana is on the short list of locations for the new plant.
What's planned

4.2-liter V-6 -- 190 hp, 455 lbs.-ft. of torque
5.6-liter V-8 -- 260 hp,597 lbs.-ft. of torque
Single overhead cam with 4 valves per cylinder
Variable nozzle turbochargers
Piezoelectric fuel injectors

Yeah I know most of you space out when someone mentions pickups but this article is for the people who care and who are more enlightened. I can say with 260 hp and 597 lbs.-ft. of torque the thing is going to be a friggin beast.

Have you ever seen the show TRUCKS! ? I feel like you'd be all over some of the jobs they do.

I've seen it, it's ok.

[matt_shaw]

I love the Cummins the motors.

[patrick10]

yea cummins kicks ass

[DILLIGAF]

The V6 doesn't sound too shabby either.

[jayhawk]

How about Cummins coming out with small displacement 4 cylinders? I think that may be the "wave of the future", diesels, come next year in America.

Imagine a Cummins 2 liter turbo diesel. If they were as strong as their straight 6 counterpart...

Yeah for some reason I loathe American cars, but think the Cummins is awesome.

Cummins already has 3 cylinder and 4 cylinder engines.

Cummins is reportedly working on a 4.2 L V6 and 5.6 L V6 for use in Dodge trucks in the 2010 timeframe[1]. This future engine family uses an aluminum head with 4-valves per cylinder and overhead cams on a thin-wall iron block. High-tech variable-nozzle turbochargers and Piezo-electric direct injection will also be used. The V6 is specified at 190 hp (142 kW) and 455 ft·lbf (617 N·m) and will compete with Ford's 4.4 L AJD-V8, while the V8 produces 260 hp (194 kW) and 597 ft·lbf (809 N·m) and will take on the current Ford Power Stroke and GM Duramax V8s.

The 5.9-liter B-series used in the Dodge Ram has proven to be very popular, disproving the myth that diesel engines are not popular with American auto consumers. The high-horsepower (larger than 15 liters displacement) engines are manufactured in Seymour (Indiana, USA), Daventry (England) and Pune (India). The Heavy duty (10-15 liter displacement) M and X series engines are manufactured in Lakewood, NY. The B, C and L series engines are manufactured in numerous plants across the world.

Here is some information on some current Cummins engines.

Every big job needs a big truck with big pulling power. And that's exactly what you get with every Dodge Ram Heavy Duty pickup equipped with a Cummins 610 Turbo Diesel. These trucks out-muscle every other pickup on the road with their combination of horsepower, torque, towing and payload.

Every Cummins 610 Turbo Diesel engine delivers a class-leading 610 lb-ft of torque at 1600 rpm, along with an unbeatable 325 horsepower and unsurpassed reliability. No wonder it's the choice of over 70% of all Dodge Ram 2500 and 3500 buyers.

Our new Turbo Diesel delivers significantly improved performance and has increased braking capacity, with easy maintenance and a 7-year/100,000-mile (160,935 km) warranty. Best of all, it's certified for use in all 50 states.

With its dual overhead cam design and Variable Geometry Turbocharger, the ISX is clearly ahead of every other on-highway engine.

Ratings begin with the ISX 385 ST and top out at 565 horsepower, with 1850 lb-ft of peak torque. The Intebrake™ system goes even higher, with up to 600 braking horsepower, standard. And with the highest power-to-weight ratio in its class and Load-Based Speed Control, it's no wonder the ISX is also the fuel economy leader. Not much is changing in the service department either, aside from the recommended CI-4 oil.

They also seem to be the only American automotive company making money

The current cummins 5.9 is due to be replaced with a new 6.7L in the near future in Dodges HD trucks as well. HP and torque ratings are about the same as the old 5.9L, but the engine meets the new stringent US diesel emission regulations.

My father has a dodge 2500 with the cummins.. 300hp and 555lb-ft of torque really moves you.. regardless of how much the truck, or trailer your towing weighs..

Yeah but isn't the point of a Diesel to save fuel? I somehow doubt these do.

The point of a diesel is to be a torque monster, which can translate to either fuel efficiency or stump pulling. No prizes for guessing what these diesels are for

In Europe, sure, but in America diesels like these here are used to tow big stuff like horse trailers, boats, and the occasional Spec Miata or two.

[HuevosRancheros]

If Cummins went to KIA, i would drive their trucks.......

From first hand experience, it is very impressive motor. 610lb ft of tq really gets the truck going. I will never own another gasoline powered truck that is for sure. You can extract over 1000lb of tq with minimal modifications.

(here is mine in a 2006 Ram 2500 4x4)

[Cobol74]

Cummins - I had never heard of them, I am now enlightened. Does this stuff cross the Atlantic any one know?

[HuevosRancheros]

According to my current issue of Diesel Power magazine, Cummins has a manufacturing facility in Daventry England where they manufacture a 23 (V-6) and 45 (V-12) liter engine for industrial and "off highway" use.

18mpg pulling a 35' fifth wheel with triple slides weighing in the neighbourhood of 10,000lbs..

seems like pretty good milage to me.. LOL

BullyDog Diesel kit + propane injection = 800hp+ and over 1200lbsft or torque. For petroleum, diesel is the future IMO.
