It may surprise a lot of people to read this but I never intended to buy a Dodge Ram in 2007. My intention was to buy the best Diesel/Transmission package in a 1 ton truck that was on the market and the first thing I learned was that in my opinion the Cummins 6.7L was the best Diesel engine in a 1 ton truck in 2007. This Engine just happens to be installed on a Dodge Frame with a Dodge body covering them. If they would have been in a Ford or Chevy then that's what I'd be driving but the site would still be called Cummins Ownerz.com and the following information helped me to make my decision and only time and miles will tell me if I'm right.


The Dodge Ram Heavy Duty pickup with the 6.7-liter Cummins Turbo Diesel engine offers more horsepower, more torque, and enables 2010 emissions compliance while delivering these power/torque increases. The 6.7-liter Cummins Turbo Diesel engine replaces its 5.9-liter predecessor and provides superior trailer towing, acceleration, throttle response and driveability. It builds on the long tradition of durability of the Cummins Turbo Diesel.
Other feature enhancements are improved combustion, integrated braking, and improved integration of engine and vehicle systems for optimal fuel economy.

Strongest.
Now in the Dodge Ram Heavy Duty truck, an integrated exhaust brake is available direct from the factory. Utilizing the 6.7-liter Cummins Turbo Diesel engine's turbocharger, the exhaust brake significantly improves control when towing heavy applications, such as pulling RV fifth wheels and horse trailers, providing added vehicle control and vehicle brake savings by transforming horsepower into braking power. This extends the vehicle brake life, resulting in reduced total cost of ownership. Testing has also shown a more-than-30-percent improvement in engine-retarding torque at 2000 rpm compared with aftermarket exhaust brakes. In addition, the vehicle features "smart" tow/haul controls that provide customers with flexibility and increased safety when towing heavy loads.
This engine is rated with350 HP at just 3013 rpm. The 6.7-liter Turbo Diesel achieves a peak torque of 650 lb-ft at 1500 rpm for the automatic transmission configuration and maintains that peak torque all the way to 2800 rpm (a "best in class" capability for a heavy-duty diesel pickup) and a full 610 lb-ft peak torque for the manual transmission.
Nearly 40 percent of the 6.7-liter Cummins Turbo Diesel engine parts are carryovers from the 5.9 liter, with modifications geared to surpass emissions standards and increase horsepower and torque, while maintaining the durability associated with Dodge and Cummins. The in-line six-cylinder product has fewer components than V8 engines. Fewer parts translates into fewer opportunities for things to go wrong. And it's been thoroughly tested through every stage of development for over eight million customer-equivalent miles to ensure dependability and durability in every kind of work environment.


Cleanest.
This engine utilizes a third-generation High Pressure Common Rail (HPCR) fuel system and has pressure capability of up to 1800 bar (26,000 psi). It is a highly flexible system that achieves a total package of lower Noise, Vibration and Harshness (NVH), reduced emissions and improved fuel economy. This engine unilizes cooled exhaust gas recirculation (EGR) and other air-handling concepts, including Cummins own proprietary sliding-nozzle Variable Geometry Turbocharger to give optimum boost level as a function of engine rpm and load. The multi-injection-capable fuel system is then used to manage in-cylinder conditions to limit emissions. The particulate filter reduces Particulate Matter (PM) levels by 90% of pre-2007 levels.
Leapfrogging the competition, the 6.7-liter Turbo Diesel engine met the more stringent 2010 EPA NOx standard a full three years ahead of the requirements. Cummins is the first diesel engine manufacturer to have a product certified to the 2010 EPA heavy-duty engine standards for oxides of nitrogen (NOx) and Particulate Matter (PM) emissions, making it the cleanest heavy-duty diesel engine available in North America.
Cummins fully supports the development of renewable energy sources. This engine's fuel system has the ability to run with B5 Biodiesel as standard. The engine has also been designed to operate on ultra-low sulfur diesel fuel (15-ppm sulfur).


Quietest.
As an added bonus, this engine is 3 dBA quieter (~1/2 the engine noise of the 5.9-liter Turbo Diesel at all points on the engine speed operating range). The 6.7-liter engine incorporates several features that contribute to a 50 percent quieter engine and significant reduction in cabin sound levels, increasing the vehicle's overall refinement. This provides owners with the quietest engine in the heavy-duty diesel pickup truck market.
Maintenance is kept to an absolute minimum, with easy access to all service points.

Of course, both the Dodge Ram truck and Cummins engine are fully covered under a comprehensive warranty that shows how much confidence we have in its reliability and durability.
