There’s probably a few things this truck has that normal cars don’t have.
The air compressor comment was an illustrative tougue-in-cheek comparison, not a serious suggestion.
Imagine the amount of power needed to run an air compressor with a displacement in the 5-6 liter range. That’s exactly the amount of power we’re talking about. Because that’s literally what an engine-braking truck is doing, it’s driving its engine as an air compressor.
Your “tens of thousands of watts” estimate is probably just about right. And that’s not anywhere outside the realm of doable. That’s probably well within the abilities of regenerative system in the drivetrain this vehicle will have, but even if we assume it isn’t, a 10kw resistive load is a $100-$200 part, off the shelf.
