The 2026 Ram 3500 offers two proven engine options, each designed for a different type of heavy-duty truck owner. Whether the truck is being used for daily work duties or serious towing, Ram provides a clear choice based on power delivery, operating costs, and workload demands.
The standard engine in the 2026 Ram 3500 is the 6.4-litre HEMI® V8 gasoline engine. This naturally aspirated V8 delivers strong horsepower and smooth acceleration, making it well suited for drivers who use their truck every day and tow on a regular—but not constant—basis. It offers dependable performance for job sites, equipment hauling, and recreational towing while maintaining simpler maintenance and a lower upfront cost compared to diesel. The gas engine is also quieter in daily driving and performs well in colder climates, making it a practical choice for many Canadian truck owners.
For buyers who demand maximum pulling power, the available 6.7-litre Cummins® Turbo Diesel inline-six is the clear upgrade. This engine is built for extreme workloads, producing massive low-end torque that makes towing heavy fifth-wheel trailers, goosenecks, and commercial equipment feel effortless. The diesel option delivers significantly higher towing capability and better efficiency when hauling heavy loads over long distances. While it comes at a higher purchase price and includes additional maintenance considerations, the Cummins engine is valued for its durability and ability to handle continuous heavy use.
Choosing between the two engines comes down to how the truck will be used. Drivers who want a capable, versatile heavy-duty pickup for mixed daily use and moderate towing will find the 6.4L HEMI V8 more than sufficient. Those who tow large trailers frequently, operate in commercial environments, or need maximum torque and long-haul efficiency will benefit most from the 6.7L Cummins Turbo Diesel. Both engines reinforce the Ram 3500’s reputation as a highly capable and customizable heavy-duty truck.
