GEN III - When will we see the first prototype

[Yggdrasill]

Would two small motors allow you to re-capture more energy/power (sorry I don't know the proper term) through regenerative braking than a single large motor?

Regnerative braking works best with all-wheel drive, followed by front-wheel drive and rear-wheel drive being the worst. But the difference isn't that big.

Could the range of an EV with two small motors be longer than the range of an EV with one large motor?

Probably not. Drivetrain losses will be greater with AWD. The improved regenerative braking really only offsets some of the added drivetrain losses.

Also remember that there is a limit as to how much charge you can put back into the battery pack. This could easily be met with just rear brakes. So even if you could generate that much current, can you stuff it into the batteries?

The Model S can charge at least at 90 kW. I suspect that 90 kW of braking on the rear wheels is too much. It's probably limited to less than that.

A Leaf regens a max of 30 kW, even though it can charge at a higher rate than that, and that's on the front wheels. I'm thinking it's limited mostly for safety because the braking isn't on all four tires.

To a good first approximation, the cost of electric motors increases with the square-root of the rated energy. E.g., a 400kW motor costs twice what a 100kW motor costs.

At the Supercharger reveal I was told we were not let in the building because Bluegenlll is underway.

I specifically asked if there was a full sized clay model in there. Answer, "No"

Is there a smaller clay model? "No".

So it sounds like they are just in the drawings phase now.

But, I gather Franz has had something in his head for a while now...

Do I believe them? "No."

Conspiracy!

 

[Grendal]

Conspiracy!

They didn't want you to see the alien spacecraft they had hoisted up. They were pulling all the proprietary technology out to put in the Gen III car.

 

[JRP3]

Maybe modern design has progressed beyond a primitive lump of clay? They should have 3D printers spewing out prototypes by the dozens. Or at least a 5 axis mill cutting foam bucks.

 

[Krugerrand]

Conspiracy!

NDA!

P.S. Just needed to add that so my msg was long enough.

they could use a little cash and im ready for a reservation on gen 111. my guess one month after model s gets to maximum monthly production. tesla has brought back kids dreamsand half the fun is in the wait and expectation. i think theres alot of money waiting for gen 111 reservations. the excitment will highten with the prototype. have fun.

It has to be past the drawings-only phase - if they only had drawings, those could be easily put away and people allowed in the building. My guess is that they'll reveal and give rides in a prototype at a Model X reservation holders' party.

I think it may be a bit longer than that depending on if they want Gen III news next or Model X. If X, we need to see another revision mid to late summer next year. Then I'd say late 2013 or early 2014 we see Gen III a year and change ahead of its 2015 launch.

I'll be someone's guest to this party. Never miss a Tesla party if you can.

True that. Tesla parties are phenomenal.

Not that it matter one whit but why would he lie?

We will speculate for months either way.

Maybe he didn't lie. Maybe [dum dum dum] ... it's PAST the clay model stage and they had a prototype in there!

That was my initial thought also...
