I don't think Tesla will make a 100 kWh Model 3 as as soon as 2017. Not because they can't, because it's quite doable, but because the price will be relatively high with not much additional utility.
Assuming the base Model 3 has a 55 kWh battery and goes 220 miles, an 80 kWh Model 3 would likely go around 310 miles, while a 100 kWh Model 3 would go maybe 375 miles. And assuming a 250 USD/kWh pack retail cost, the 55 kWh Model 3 would be 35,000 USD, the 80 kWh Model 3 would be 41,250 USD, and the 100 kWh Model 3 would be 46,250 USD. I don't think many customers would be willing to pay the extra 5k USD to go from 310 miles of range to 375 miles. At this point the range is good enough.
Additionally, allowing as big a spread as 55-100 kWh means the battery pack volume and battery pack structure in the base Model 3 is almost twice as big as needed. This adds cost and complexity to the base model, to allow for the high end 100 kWh battery. Tesla will probably sell very many cars that are fairly close to base configuration, and they really need to squeeze out all possible profit margin.
Instead of a 100 kWh pack for the Model 3 in 2017, I think that a 120 kWh pack for the S/X is likely. We should see 21-70 based packs for the S and X in 2017. For those who need range in the 350-400 mile area, they will need to go up a class.
A very good post. Well reasoned. I just see the same data through a different lens, yielding an alternate result.
My feeling is that Tesla Motors may well have learned from their mistake with Model S. That is, in particular, not realizing that the grand majority of buyers would go for the highest capacity battery pack from the start, and ever since. I believe that they will offer the Model ☰ in trim levels that will make the most of the
'medium' capacity in such a way that it is
'enough' for the vast majority of buyers. And that the
'low' capacity entry level car will have
'adequate' range to meet the stated parameter for Tesla Generation III -- 200 miles range, minimum. I think that the
'maximum' capacity battery pack should be paired strictly with the Performance iteration of the car.
If so, then I think the sales split will be about 30%
'low', 50%
'medium', and 20%
'maximum' capacity. That would allow the
'medium' and
'low' capacity cars to be built using the same physical battery pack, but with it software limited to a lower capacity in the less expensive car. Economies of scale will allow that to work in a profitable fashion, regardless of chosen options on either. And those who want the
'maximum' capacity battery pack installed in a less expensive vehicle configuration with the Performance profile of a Toyota Yaris or Prius or Mirai can just chew glass and kick rocks.
I think that doing things that way will handle your concerns fairly well. The tricky part is that I believe the Tesla Model ☰ in Performance trim must also be a bargain compared to its competitors. So, fully loaded, it would cost about the same as the base version of the BMW M3. That would put the Model ☰ in a position to completely destroy all the others: Cadillac ATS-V, Mercedes-AMG C63 S, Infiniti Q50 Red Sport, Lexus IS F-Sport, AUDI S4, Jaguar XE S, Alfa Romeo Giulia Quadrifoglio, and anything else on the horizon. Balancing the Performance Model ☰ price point so that it is a no-brainer to those considering other marques, while not being a temptation to the vast majority of Model ☰ buyers may well be... difficult.
So, again... I'd only include the highest capacity battery pack in one configuration, the Performance iteration, nothing else. Yes, that package would include mandatory big wheels and staggered tires, dual motor all wheel drive, and the highest capacity battery pack. The idea is to drive home the point of this car is to thoroughly embarrass ICE vehicles in the Street Light Grand Prix. So it would be a bit more than $5,000 over the
'medium' variety of the car -- which I would see as a Model ☰ 75D. Thus, the
'maximum' would be the Model ☰ P100D. And the
'low' level car, the base level entry variety, would be Model ☰ 55 with rear wheel drive.
The way I see it, you could order one of three cars, then alternate configurations would be based upon the options chosen from those starting points. Here is something like what I have in mind:
Model ☰ 55
$35,000 base price
215 to 225 miles range
Get Dual Motor AWD as a separate option to be Model ☰ 55D (230 to 255 miles range)
Get software unlock of battery pack to get Model ☰ 75 (270 to 300 miles range) with Free for Life Supercharger access
Up to $15,000 of other options available beyond base configuration
Model ☰ 75D
$42,000 base price
280 to 310 miles range
Free for Life Supercharger access included
Up to $15,000 of other options available beyond base configuration
Model ☰ P100D
$50,000 base price
320 to 360 miles range
Free for Life Supercharger access included
Up to $15,000 of other options available beyond base configuration
Please note the highest capacity you can get with rear wheel drive is 75 kWh. And, that at 75 kWh or higher, Free for Life Supercharger access is included by default. A person with $50,000 on hand to spend would have some decision making to do -- get a fully loaded Model ☰ 55, or a base Model ☰ P100D, or a modestly upgraded Model ☰ 75D. Ultimately, I think that is just fine. Those on a hard budget under $45,000 would just get something that included a 75 kWh battery pack. And they'd be happy, I think.
