Cummins to release video series on benefits of diesel

COLUMBUS, Ind. — Cummins announced that it will be releasing a five-part video series that highlights the benefits of diesel powered motorhomes compared to their gasoline counterparts. The video series is hosted by Evie, Cummins RV road travel expert, with each short video covering a different topic, including: fuel economy, hill climbing capability, noise comparison levels, vehicle braking differences and customer support.

Cummins produced the video series to educate customers on the ways a diesel choice can aid in RV travel, both economically and logistically. The video series shows consumers, through demonstrations, the benefits of diesel powered RVs for excursions across the country, including overall savings on mileage and improvement in travel comfort levels. With various field tests on how diesel works for an RV, the video series yields compelling results regarding the differences between diesel and gasoline for powering motorhomes.

“With this video series, we want to demonstrate to consumers the numerous benefits behind choosing a diesel powered RV and how beneficial diesel fuel can be for traveling near and far with their Cummins RV diesel engines,” said Jodie Wilson, marketing communications director at Cummins Inc. “Creating a fun yet informative series and laying out all the facts on diesel powered motorhomes will give consumers the chance to decide for themselves which type of RV is best for them.”

The videos will be available on the Cummins RV website, as well as the Cummins Engines YouTube channel and the Cummins RV Facebook page.

More facts on diesel fuel:


  • Slowing down your speed by 10 mph can save up to one mpg.
  • Keeping your tires properly inflated can improve fuel mileage.
  • While it can take up to 8 minutes to fill an 80-gallon tank of regular gas, it only takes about 3 minutes to fill a 100-gallon tank of diesel fuel.

Speeds at Different Grades

  • Diesel powered RVs maintain higher speeds on grades without downshifting and with almost half the noise.
  • Diesel coaches deliver 50% more torque, which results in stronger uphill acceleration in coaches and less downshifting.
  • The result is that going up a hill with an 11% grade, the diesel-fueled RV maintained a speed 7 mph greater than gasoline.

Noise Comparison Levels

  • Diesel coaches use air suspensions for a smoother and quieter ride, resulting in less driver fatigue, while gasoline powered RVs use multiple-leaf spring suspensions.
  • Since diesels are generally used in a pusher layout configuration, not only is the noise level less, but it is also further away from the driver, resulting in less fatigue.
  • Not only are diesel generators quieter, but the generator is located 30 feet away from the bedroom on a diesel pusher, resulting in significantly less noise as customers relax.
  • On hills, our diesel climbed with 20 dB less noise, which is 4 times quieter than gas, and equivalent to the difference of a normal conversation vs. a food blender.


  • Supplement exhaust braking systems on diesel coaches provide drivers with greater confidence going downhill, with a reduced risk of glazing, overheating or fading, which increases better control on steep downhill grades.
  • During an emergency brake maneuver, our diesel powered coach stopped 50 feet shorter than our gasoline coach and had much lower brake temperatures after extended braking.
