Hi,

But does a BEV have such a drive train?

If the OEM certified their vehicle for Recreational tow, it's capable of towing.

The problem comes from rotating parts in the drive train getting enough lube and/or cooling.

Here is a further explanation from the salesman.

"As it has what’s called the regenerative breaking that is part of the electric motor system when the wheels are spinning the engine is working as well so it is recommended to be on a dolly or a flat deck. "

What BEV do you own?

Where we live in Canada I have never seen my range drop more than 30 percent. Then again our commute is only about 20 km per day so kinda doesn’t matter.


Hi Don. We live in a part of B.C. that has pretty mild winters. Rarely goes below minus 15. We have a first generation Leaf. It has a heat pump so a little less susceptible to range loss in winter.

Yes all EVs need to be on a trailer. Some 2wd might get away with a dolly.

The reasoning is just corporate BS. Still waiting to hear a story of someone pulling an EV 4-down. No one is brave enough to do this with a $40,000+ car. Maybe when it is about shot someone will give it a go.

I believe the transmission is just not designed to push the motor for hours on end. There is no disconnect or mechanical "neutral". Very easy to have the motor at 5,000 to 8,000+ rpm going down the highway.

So there is no 'park' position for the car? And no neutral?

Hi Bobbo,

Are you saying you know folks who do a 150 mile commute?

Bobbo wrote:


But, range is very relevant if you have a long commute and are trying to decide on whether an EV is suitable for you.

Yes, I am.

I have a friend whose wife is stationed at Blytheville Air Force Base, and will be till her hitch is up in about 2 years. He commutes, every day, to Memphis, TN.

In icy weather, I let him stay at my place to keep him from driving that distance on iced over streets.

Never lose sight of the fact that other people have other needs than you do.

There is. For Park some use an automatic parking brake and some have a parking pawl. Some have both.

Neutral just powers off the main electric drive motor... no mechanical disconnect. Wheels and motor always turn in unison together through about 7:1 gear ratio. Yes you can put it in Neutral while driving at speed and the motor just continues to spin. Just electronic disconnect.

Been reading www.mynissanleaf.com since the initial orders were placed in May 2010. Mine included.

There are people on there that have hacked and disassembled just about everything. You think we have lengthy talks here.... it is nothing compared to some details on how these EVs work. It is a busy forum and virtually all cars are covered to some extent.

Drove the Nissan LEAF 3 years, RAV4-EV 5 years, now the I-Pace gets me around.

Ahhh. Makes sense. I am yet to get up and personal with the Ipace but looks nice from a distance. We’ll spend part of the winter in California this year and I’m sure the local dealer will have one. Otherwise we’ll be in Europe next year and I know they’ll have them there.

Cheers.
