You could nearly double your range by buying two model Y’s it would give you around 600 miles — a much better price, and theoretically you could tow charge one and charge it, so it’s not out of the realm of possible.

To be fairrrr, only people that have range anxiety are those that listen to the oil and gas industry.

[tlb]

Are you suggesting that driving around with 2 cars, one towing the other, will double the range?

Moving 2 cars together takes almost double the power. The aerodynamic drag can decrease slightly — work on semi trucks in close convoy formation suggests maybe 10-20%.

[tdhz77]

No, you have double the range by having two cars for less than 100k. I’m saying at least at this point you at least have a chance at using batteries to recharge batteries.

It’s common knowledge that you can do this.

At that point maybe somebody could start selling a ginormous battery pack on wheels. Buying a second car just to increase range seems ridiculous.

[tdhz77]

More ridiculous than buying 1 car for double the price? I’m confused.

[yoz-y]

People pay twice the price for other reasons too. Performance and cost seldom have linear relation.

[tdhz77]

You can say that about anything. The point here is that buying a Model S/X for 100k instead of buying two Model Y cannot be defended by performance metrics alone.

> you could tow charge one

This doesn't work out. The extra drain on the towing car more than makes up for the regen that the towed car gets.

> and theoretically you could tow charge one and charge it

Charge it... from where? There isn't a free energy source here...

[tdhz77]

The fact that you can charge an electric vehicle by towing it in gear is common knowledge among those with knowledge of how EVs work - you're basically just relying on regen to put juice back into the battery, using the motor as a generator.

[gpm]

You can, but it's not an infinite energy machine, the increased resistance to moving forwards is going to suck more energy out of the first vehicles battery than it is going to put into the second, your total range will be strictly less than if you didn't do that.

[tdhz77]

You have 0% energy added by having one Model x/S. How impractical it is, fine: but, the fact you might be able to do it in the future gives model y’s cars the better decision over one Model X/S
