Tesla Model X Tows Model S And Recharges It – Video


It turns out, you can charge a Tesla Model S by towing it.  And what better vehicle to tow it with than a Tesla Model X?

Here Are The Stats

Here Are The Stats

Maybe not … the Model X can tow 3,500 to 5,000 pounds, depending on which wheels you choose.

Being that the Model S weighs in just shy of the 5,000 pound mark, this is a risky experiment, so we hope that the Model X is equipped with 20″ wheels. Added to this, Tesla does not recommend towing its vehicles, and will not cover any damage resulting from towing a Tesla without a flatbed.

This concept has been demonstrated before, but this time it came from Bjørn Nyland and crew. The video simply shows a split-screen of the instrument gauges in each vehicle, so you can watch the range grow as the towing is happening. Though it is not really a good idea, it’s pretty cool to see that it works.

Video Description per Bjørn Nyland:

What happens if a Model X tows a Model S? Due to the length of the rope, we couldn’t drive faster. Therefore we didn’t reach the maximum regen which is 60 kW. Not long after we started pulling, a yellow dotted line appeared on the Model S. This limits the maximum regen. The Model S is a single motor rear wheel drive standard 85. Maybe if we used a dual motor, we would get higher regen.

Hopefully, with Tesla now planning to charge for Supercharger access, people don’t get any crazy ideas!

Nothing but time to burn.

Why wouldn’t it work? Was there ever a doubt?

I wonder what happens if you drive a MS down a mountain? Would it charge itself on the decline…..?

Yes it would and yes it does.

I have driven over 2.5 million miles in 41 years 1.5 million as a taxi driver
approximately 400000 miles on Toyota Priuses
while driving uphill I ran out of gas so I made a u-turn and glided down the hill
I was able to recharge the battery enough to drive approximately two and a half miles to a gas station yes it can be done

This is a pretty idiotic posting.

What would really be interesting would be direct charge transfer from one car to the other; a la, you run out of gas and you siphon some from another car to get going again.

This is super cool.

I wonder what caused the regen limit? Heat in the rear motor?

This was done with a LEAF years ago. But still pretty cool, admittedly. 🙂

Wouldn’t the effective weight of the Model S (or other towed EV) increase by quite a bit because the regen is effectively pulling backward on the towing vehicle? No wonder the Model X only got LESS THAN HALF A MILE PER KWH at only 25mph!(!!) When its normal efficiency @25mph has to be 3+ mi/kWh. If we got numbers on the same tow with the S in neutral, that would answer more questions.

This puts the lie to Tony Williams stating a car may only be charged by pluging it in. Or that cars only have one charger in them.

The plug-in charger in this case, was unused at the time.
