Which Dodge RAM is Diesel?

Which Dodge RAM is diesel? Several generations of Dodge RAM models offered diesel engines from 1989 through 2008, before RAM became an independent brand in 2009. Orange Coast Chrysler Dodge Jeep® RAM FIAT serves Costa Mesa drivers seeking information about these legendary Cummins® diesel-powered Dodge RAM models that defined heavy-duty truck capability.

Dodge RAM Diesel Models by Generation

First Generation (1989-1993): The Original Cummins Partnership

The 1989 Dodge RAM introduced the first 5.9-liter Cummins® diesel engine in D200 and D300 models. This twelve-valve inline six-cylinder produced 160 horsepower and 400 lb-ft of torque with exceptional 25-mile-per-gallon fuel economy.

Second Generation (1994-2002): Enhanced Performance

Dodge RAM 2500 and 3500 models featured the improved 5.9-liter Cummins with Bosch P7100 mechanical injection pump through 1998, then switched to the 24-valve VP44 electronic system for enhanced performance.

Third Generation (2003-2008): Modern Diesel Technology

The 2003-2007 Dodge RAM 2500 and 3500 models received major upgrades with common-rail fuel injection and completely revised interiors featuring expanded Crew Cab and Mega Crew Cab options. The 5.9-liter Cummins proved exceptionally popular among enthusiasts for its balance of power and reliability. Dodge replaced this unit with a lower-emissions, higher-output powerplant displacing 6.7 liters to meet stricter EPA standards.

The RAM Brand Emerges

After 2008, Dodge RAM became the independent RAM brand in 2009. Models built in and after the 2010 model year are RAM trucks and no longer bear the Dodge name. However, we’re still proud of that history, because it laid the foundation for today’s heavy-duty RAM success, with modern RAM trucks continuing the Cummins partnership that began over three decades ago.
