Could Honda finally take on the heavyweights like Ford, Chevy, and Ram? A 2026 Ridgeline HD powered by a long-lasting diesel V8 might be in the works. Here's everything we know so far.

Why Honda Needs a 2026 Ridgeline HD in the Heavy-Duty Segment 

The current Ridgeline is known for its car-like comfort with the utility of a midsize truck. But it doesn’t yet compete in the heavy-duty segment—a category where towing, torque, and toughness define success.

If Honda releases a Ridgeline HD, it would mark the brand’s first serious push into full-size pickup territory. And for that, it needs an engine capable of delivering power consistently for decades.

Will the 2026 Honda Ridgeline HD Get a Diesel V8 Super Engine?

Today’s Ridgeline uses a V6. But to step up into HD territory, Honda will need to up the ante.

Two likely engine options:

  • V6 Turbo: Balanced for efficiency and daily driving

  • Diesel V8 (speculative): Designed for heavy loads and long-term use

Diesel engines are industry favorites in HD trucks because of their torque, durability, and towing strength. A rugged diesel V8 could help Honda compete with:

  • Ford’s Power Stroke

  • Chevy’s Duramax

  • Ram’s Cummins

What Makes a Long-Lasting Engine? 

Honda is already respected for building engines that last hundreds of thousands of miles. If it builds a Ridgeline HD, that reliability would need to be taken to another level:

  • Heavy-Duty Components: Reinforced pistons, rods, and crankshafts

  • Advanced Cooling System: Prevents overheating during towing

  • Optimized Lubrication: Keeps parts running smoothly for decades

  • Real-World Testing: Proven performance under extreme stress

If done right, this powertrain could become a major selling point for fleet buyers and long-term truck owners.

Could the 2026 Honda Ridgeline HD Change Things for Honda?

A Ridgeline HD with a super-durable diesel V8 would be a bold move by Honda—one that could reshape its image in the truck world.

  • Fleet buyers may see value in fewer maintenance costs over time.

  • Personal owners may appreciate the peace of mind of owning a truck built to last decades.

  • Truck enthusiasts may finally get a heavy-duty Honda to rival the American giants.

How Many Tons Can the Honda Ridgeline HD's Super Engine Carry?

The 2026 Honda Ridgeline HD is expected to have a much higher payload capacity than the current midsize Ridgeline, thanks to its "Heavy Duty" (HD) classification. To compete with other full-size trucks like the Ford F-250/350, Chevrolet Silverado HD, and Ram HD, the Ridgeline HD will need to offer a strong payload rating. Most trucks in this category have payload capacities starting around 3,000 lbs or more, depending on the model. This increased capacity will make the Ridgeline HD suitable for those who need to carry heavier loads.
