Follow the evolution of Litre Cummins 5.9L to 6.7L pickup engines
The Cummins 5.9L inline 6-cylinder was a fan favorite in RAM pickups for years, and when it evolved into the 6.7L Turbo Diesel mid year of 2007, a variety of enhancements – along with greater displacement – made it a real crowd pleaser. RAM owners gained a lot more power, improved fuel efficiency and a quieter, cleaner-running engine
Through the years, Cummins has promoted higher power density turbo charged diesel engines, and that dedication to power can be seen in today’s RAM pickups. As our technologies have evolved, the 6.7L Turbo Diesel continues the Cummins legacy of performance and legendary reliability.
The original 5.9L Cummins B-series engine was a revolution in its day, and the introduction of the ISB5.9 in 1998 gave RAM drivers even greater power. That engine’s four valves per cylinder and electronic engine management made it a favorite among drivers. During its nine-year run in RAM pickups, power numbers accelerated, growing from 215 HP and 420 lb-ft torque to 325 HP and 610 lb-ft torque.
5.9L would need to evolve in order to continue exceeding.
In January 2007, cummins introduced 6.7L Turbo Diesel for pickups, bringing a 13% increase in displacement and some exciting new technologies. Out of the gate, it bested 5.9L power output and met stricter emissions regulations.
The model-year 2013.5 engine introduced a number of performance and environmental enhancements. The addition of SCR (Selective Catalyst Reduction) technology delivered a 10% boost to fuel efficiency and another increase in peak torque, while doubling the 6.7L’s oil change intervals.
The new 6.7L Turbo Diesel retains the familiar cast iron block and cylinder heads of the 5.9L, but advances in fuel and air delivery change nearly everything else, especially power ratings and maintenance intervals – now at 15,000 miles. The 6.7L produces up to 900 lb-ft torque and 385 HP. Plus, full torque is reached at a low 1,700 RPM.
The Cummins 5.9L B series turbo diesel engine blazed the trail that the 6.7L travels today, elevating performance in 3/4- and one-ton pickups and large commercial chassis cab applications. The versatility and efficiency of the 6.7L Cummins is reflected by its commercial brother, the ISB6.7, a leader in the medium duty truck, marine, and industrial markets.
