Sure !. They just change the "Target" to suit whatever the production actually is !
Originally they set a target of 200,000 by end of dec 2017 (10,000/ week ?)..failed
That was revised to 5,000/week by end Dec'17.....failed
Later revised to 2000/week by end March '18 .... Nearly made it, (took until 1st week of April)
Latest target is 6000/week by end of June ??
Currently they are running at 2050/week,..so they will have to tripple production rate in 7 weeks .
I think there may be another revision of the target rate before then !

For me I think the future maybe an electric conversion of a current ice car with a crashed electric donar and use custom controller.

Well, you can get a used Leaf for almost nothing. Get the Leaf, put a 50kWhr battery in it and you'll have a very low cost EV. And you won't need a custom controller or motor plate or anything, just some electronics to spoof the battery's CAN bus interface.
If I was going to build a custom Ev I would try to pick a complete drive unit for example a tesla rear motor and use that in the front of a small hatchback type car it's not going to break any records but make a nice run around, To interface the drive would be custom engine mounts and drive shafts rather than the old school method of using the existing box and an adapter plate.
Diy builds are getting better by the day thanks to production Ev that are wrecked same as the ice tuners pull engines from gtrs etc, I've played that game of get the biggest engine and turbo and watch the car rocket or the engine grenade I think retro electric mods will be a big thing I think well it already is and can only grow now.

A rear Tesla Drive unit can do well over 500hp!
I think even a front Tesla unit or a leaf motor would be fine. IN fact I think the leaf motor can make more power than the front Tesla unit.

Anyone see the twitter storm from Musk when he cut off investors about M3 production? Apparently, those analysts were in fact quite bullish and supportive of Tesla. And Musk just hated being asked questions about M3 production.

Your build thread is awesome and inspiring to say the least,
With the leaf motor being an ipm it should have a better power to weight ratio than an induction being an advanced motor an all so even if it is slightly behind on overall power it could still make a decent choice really for optimum performance and good efficency
I read the rear tesla unit revs to 16000rpm and the leaf does 10200rpm.
I like small wide wheels on a little hatchback and the leaf may only give around 85mph with wheel gearing but a very decent 0-60 dash and in the UK 85mph is plenty when u got 9 points.
The tesla unit will be a different beast all together more power, faster top end and a bigger battery needed for range and discharge purpose so bit more weight to for it all to mesh and be fun, first option fits best for me.

I'm running the leaf motor to 15,000 rpm.

If anyone wants to donate a rotor or whole motor from a leaf I will spin one to destruction so we can determine the true safe max RPM

Be nice for a big website fundraiser and get a video up thats mandatory to like because its engineering porn, two of them would be nice rev one up and keep loading it till it frys get temp and torque data and then spin one up with no load on in a open area and let it rip much better than the guy that frys vacuum motors pfft lol.

The thing with "frying" a motor is there is a current that will fry it in 60min and a current that will fry it in 1 minute and a current that will fry it in 10 sec. And they all vary from one another and depend greatly on cooling as well as other variables.

Good point, load it to the equivalent weight of a modded crx say ;) and then see what it can take in ten second bursts leave it cool inbetween each run to find its max burst torque, probably see it through the dyno data and a temp gun before a full meltdown, then do the destruction test so you know the max initial burst torque and the max frequency it can take.
But by the looks of it you know that 750amp and 15000 rotor rpm is acheivable and I'll buy that for a dollar, a big tap on the back and I'm watching very closely good work.

Consumer Reports thinks the Model 3 is not that good.
https://www.consumerreports.org/hybrids ... mendation/

With Cnet having a report on their report https://www.cnet.com/roadshow/news/tesl ... mendation/

The problem I have with a lot of the reviews out there is that they are mostly all from hardcore fans of EVs. It wouldn't matter if the car had no wheels, they would claim its the best car ever.

For example, this guy https://youtu.be/49WftO5L71I?t=1m47s gets out of his Model 3 in full snow gear clothing because he doesn't want to use the heater because it will ruin his range and admits that the range of his Model 3 has dropped to less than half of its claimed range because of the cold is affecting the batteries.

But he never, ever, admits in his whole own blog how little range problems he has ever had on his Model 3, its all just great.. https://www.facebook.com/tsla3/

Dude.

He is Standing in eastern Canada in the dead of winter at night it was -35deg out that night. You don't go outside without some winter cloths on lol And yes the car has less range When you are using it in -30- -40 deg C weather most of your energy is going to be used up heating the interior to keep the human alive.

Shame on Tesla for keeping the occupants alive in their vehicles :roll:

Awesome cars, poorly run company. Where else can a company get away with never making a profit, and losing -$4000 per car?

https://www.tflcar.com/2018/04/tesla-fi ... 8-results/
Amazon went without making profit for many YEARS, seems to have worked out pretty well for them. People never truly accept when the world changes and they are forced to alter thier beliefs (must be like watching Ford in the beginning). Fasten your safety belt, you are about to see Tesla become one of the fastest growing, most valuable corporations in the US, all without paying anybody much of a dividend.

Name one person who's bet against Elon Musk and won?
Everyone loves to compare Amazon business model and its famous continuous financial losses to other companies like Tesla, but I think its got some serious differences. Amazon quite literally has its fingers in everything, from Cloud/AI to food-supermarkets and pizza delivery via Amazon Prime. Tesla is pretty much just cars and Solar panels.

There are some equally famous people who are directly betting against Elon/Tesla like Jim Chanos.
https://www.bloomberg.com/news/articles ... brick-wall

Jim Chanos? never heard of him. Elon Musk.... EVERYONE has heard of him. I'll ask you one more time;

WHO HAS BET AGAINST ELON MUSK AND WON, EVER?

I doubt any new automaker could emerge and ramp up to Tesla's production levels without reinvesting all their profits and a bunch of borrowed money as well. It wouldn't matter whether they were building the future or just a huge pile of crap like the Big Three. Building up to that level takes more money than you can generate in the short term, if you are in the business of actually making things.

Regulatory and technical barriers to entry prevent automakers from starting small and making a profitable and competitive product during their growth period. You could do it more than a century ago, because all cars were expensive, small volume production. Today, you have to start with a huge amount of capital to benefit from economies of scale. It's the same whether you choose to build clean, efficient electric cars or giant SUVs that run on lignite coal and the tears of brown-skinned children.

We'll see whether Tesla lives up to its high stock value. The more relevant question is why do the intransigent automakers like Ford and GM have any significant stock value, when they've opted out of the future of their own industry? I don't believe they're capable of adapting rapidly enough to survive.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.

Here is my opinion, as someone who spent 50% more for an EV than a comparable ICE.

My personal belief is that nobody has yet figured out how to make money on EVs at prices close to ICE. At comparable prices we might see actual consumer demand. At this point, none of my liberal, Prius driving friends are interested in putting up with EVs. The motorheads I know have nothing but contempt for EVs.

Tesla may be able to make money on $45-75K status symbols. But I doubt there is a market for 5K a week of those. When they start showing up at Lowes in numbers, they will stop being a status symbol, so it is a Catch 22.

I hope we see really cheap batteries one day, but that day isn't here yet. I think we are likely to see a major recession before then.

In my opinion Musk is doing right thing, producing cool, user friendly vehicles accelerates their acceptance and integration of this “exotic” technology.

Good example:
Smart phones where known for many years before I got one E-ten in 2006 and HTC in 2007 and felt out of place in my surrounding.
But suddenly, in 2007, apple came out with peace of crap, that did not have half functionality of my phone and basically offended the use of “Smart phone” term by lacking basic things, like multitasking, master USB connectivity, BT connectivity to other devices etc.etc., being just placed as user friendly (I agree, even a monkey could use it) and aggressively promoted as cool product, with outstanding price tag for outstanding people.
Bam, in few years everyone got smart phone!!!

Tesla cars, in many ways, are miles ahead to competition and really deserve being market leader, in no way just hype driven product.

In that article above by Jack Rickard, he says first line of defense is the thin wire fuses, but inside the 2170 cell lids, there are two other fuses .....one CID and one PTC......, CID is simple pressure fuse ( small aluminium disc that pops out when pressure too high, it disconnects cell permanently, unless you physically reset it), the PTC fuse is temperature fuse ( very thin annular disc which resistance increases with temperature, when temp drops it resets).
Here is video claiming to show 2170 tesla cell overcharge to thermal runaway.....imagine thousands of these going off at same time, in a chain reaction event.

looks like the tesla cells might be only relying on the thin wire fuse external to cell, seems they dont have
cid or ptc inside them after all.
