There are exactly ZERO EVs rated to be towed 4 down.


And nobody ever tows a vehicle that is not "rated" to tow? And unlike ICE vehicles where the transmission probably does not lubricate when driven from wheels, nobody has pointed out a mechanical reason a EV can not be towed.

So I sent an email to Tesla to ask about their new pickup truck and if it will be towable 4 down behind our motorhome. First response from them was , what do you mean by towable 4 down ? Next email I explained how I tow my F150 behind our motorhome and wanted to know if the new cybertruck will support that. Their response was that none of there current vehicles could be towed 4 down as it would burn out the motor(s) , but they didn't have any information on the capability of the new truck. I responded that how could they be taking orders on a new vehicle when they don't even have specifications on that its' capabilities are. I imagine it will be the same-- no 4 down towing.

Mechanical reason # 1, EV's have motors connected directly to the wheels, if the wheels turn, so do the motors.

I don't know what happens when neutral is selected in our EV's but it is definitely a free wheeling feel. One can shift back and forth on the fly while moving. As soon as it is in drive you can feel the regen. I have no idea what is happening mechanically though. No idea if it could be harmed while towing. And the car has to be on and running or it applies the parking pall.

No EV has a mechanical disconnect. If the wheels turn, the motor turns.

I keep hoping someone will take the risk on a well used and cheep EV and go cross country and post a report.

The original 2011 Leafs are on cars.com for around 5 to 7000 bucks. We need to find a member with 7000 to spare and “hook it up”. [emoticon]. Not me. We kinda got used to trailering now. I don’t think I would want to go back to 4 down.

Unit confusion in this topic!

The kilowatt is not a unit of energy. It is a unit of power - how fast energy is consumed. Analogous to a gasoline car’s gallons per hour.

The unit of electric energy is the kilowatt hour. Analogous to gas car’s gallon of gas.

Driving an electric car a kilometre requires some amount of energy. How many kilowatt hours is it? How much does a kilowatt hour (KWH) cost? This is indicated on any electricity bill. It may be ten cents plus another ten cents delivery charge.


Why not just convert ecar units to gas car units? Much easier to relate to for most people:

746 watts = 1 hp
1 kw-hr = 0.03 gallons of gas

As long as you use metric units.
