I did some calculations on how far the Tesla Cybertruck could pull our 37' 20k lb 5th week trailer.
We pull it with a 2021 Chevy 1 ton Duramax diesel that averages about 9 MPG while towing.
We can tow about the trailer about 324 miles on a full tank of diesel fuel (100% to 0%). We carry another 60 gallons in a aux tank in the truck, so our total range is 864 miles vs 27.08 mile range.
I think it will probably be a while before an electric truck can match the range of a diesel.
We pull it with a 2021 Chevy 1 ton Duramax diesel that averages about 9 MPG while towing.
- One gallon of diesel contains approximately 138,690 BTU (British thermal units).
- One kWh is equal to 3,412 BTU.
- Therefore, one gallon of diesel contains approximately 138,690 BTU / 3,412 BTU/kWh ≈ 40.67 kWh.
- 40.67 kWh / 9 MPG ≈ 4.52 kWh/mile.
- Estimate the energy content of a gallon of diesel:
- One gallon of diesel contains approximately 138,690 BTU (British thermal units).
- One kWh is equal to 3,412 BTU.
- Therefore, one gallon of diesel contains approximately 138,690 BTU / 3,412 BTU/kWh ≈ 40.67 kWh.
- Divide the energy content by the fuel efficiency:
- 40.67 kWh / 9 MPG ≈ 4.52 kWh/mile.
