IIRC there were some 3-cyl engines based on the same design for agricultural tractors from Case-IH and New Holland. On a sidenote, there was a time when it used to be common to fit a 3-cyl 2.9L Diesel engine into Ford F-1000 trucks in my country as an attempt to save fuel, even though it was clearly underpowered.
An "underpowered" engine on truck chassis would seem like an opportunity to add a hybrid system... If you're alright with the upfront costs of course.

I've driven vehicles with over 30,000lbs over steep passes with less than 200hp. I wonder if there's a clear definition of what "underpowered" is or is it purely a personal point of view?
