The trailer doesn't care what kind of engine is pulling it. It just resists motion due to intertia, aerodynamic drag, and rolling resistance.Not being a truck, towing, or RV kinda guy, I have a question along these lines. If a vehicle gets X range from its tank/battery, and there is a Y% penalty for towing a given trailer. Shouldn’t the penalty be the same for ICE or EV? Same aero, same amount of energy required. Sure, with ICE you have “in/out of power band” issues with underpowered tow vehicles, but it would seem the penalty there would be worse on an ICE vehicle. I thought I read that someone on a thread said EVs were worse at towing penalty, but I don’t see why. Please enlighten me.
From that perspective, the 50% range-hit (MPG reduction) that I take from towing my travel trailer with my ICE truck should be roughly the the same with the Cybertruck.
What makes it complicated are:
- The more efficient the truck, the bigger the range-hit the trailer creates. The trailer's efficiency is fixed so, if you swap in an efficient truck, it'll lose more range pulling the relatively inefficient trailer. We won't really know how well this works until someone tries it.
- Quirky edge cases in drivetrains can cause certain combinations of speeds and loads to be more or less efficient. This is particularly true in ICE vehicles which have engine-sweet spots and multiple fixed gear ratios -- but they can theoretically happen with hybrid and EV vehicles, too. We won't really know how well this works until someone tries it.
Given that we have Cybertruck sightings daily now, but that they never include trailers, I'm starting to wonder if this thing is really being developed as a tow vehicle. We won't really know how well this works until someone tries it.
Back to the towing range-numbers, I mentally divide the range number by three to guess what the towing range of the Cybertruck will be with my travel trailer. It's a wild guess, but it's the best guideline I've got until someone does a range-test with the Cybertruck pulling a travel trailer the same size & shape as mine.
That means I'm really hoping "500+ miles" really means "620 miles", but we won't know until the specs & pricing are released.
Towing would be a big part of my justification for owning a Cybertruck, so I'll be waiting for someone else to really put it through the towing ringer before I buy. And, honestly, the inevitable Tahoe-sized 3-row SUV/van variant of the Cybertruck might fit my use-case better anyway.
