But probably someone who knows more about the topic.

Maybe maybe not, either way none of that disputes the fact that chevy went for efficiency over acceleration per several interviews with their engineers. I just mentioned several ways they could go about it considering cd wasn't better than the model 3 and their inverters and battery packs likely aren't either.An electric motor is most efficient at high load for starters. The major trade off people make with gear ratio is speed vs acceleration. If you don't need to have great acceleration it makes more sense to use a smaller motor to keep the load high instead of changing the gear ratio. This also saves on costs which is what they did with the Bolt.
There's no maybe about it, it's very different from an ICE. If the GM engineers went with a different gearing ratio they'd simply get a higher top speed. Since the top speed is already 91 and many GM vehicles are limited to 98 mph or so, they were fine.Maybe maybe not, either way none of that disputes the fact that chevy went for efficiency over acceleration per several interviews with their engineers.

Note sure what those are on the headlight. Don't think they are fasteners. Haven't noticed that on any of the other cars.Firstly: lol....
Secondly, some interesting items in that (new to me) pic:
- Fasteners around edge of headlights
- I'd guess dual forward looking cameras based on mirror cutout
- Something on dash behind center screen near steering wheel... some temporary test instrumentation?
Ok so they use a smaller less powerful motor, that would require a smaller gear, to achieve the same top speed as a larger one. This would come at the expense of acceleration. The end result is a more efficient car (all things being equal) that is able to reach the same speeds but at a slower rate. That's the same principle as a car, motorcycle and bicycle. I'm not sure how that would differ between an ice or electric car. The only difference should be the an electric motor will deliver an instant sustainable and constant acceleration all the way to its top speed without needing additional gearing. However if you look at formula e several manufacturers still opt for an additional gear in order to not sacrifice speed, efficiency, or acceleration. Even the dual motor s uses a more efficient gearing in the front for highway cruising. Perhaps I'm missing something it seems pretty straightforward to me but now I'm hogging the thread and I noticed you live in Indy so I want to stay on your good side in case they don't have any testers buy the time my number is finally calledThere's no maybe about it, it's very different from an ICE.

Anymore acceleration and they sacrifice top speed with that motor choice.
If you can find an interview, I'd like to read it.
Yep. I bet Tesla planned for a smaller base battery, but the Bolt changed those plans.
Now I'm curious to see the final EPA ratings. 3 will surely have better highway range than the Bolt, but the city range may not be a slam dunk.
That's because of the high air resistance that Model X have. Model X 90D have 90 mpg city and 94 mpg highway. Model S on the other hand have 95 mpg city and 106 mpg highway. If Tesla have made sure that Model 3 have really low air resistance it should have longer range on highway according to EPA.Actually the City range with regen should be higher than the highway range. That is my experience with my Model X.
Musk is a pretty competitive guy, I don't think he will let the Bolt out-range the M3.... not a chance.
For sure he sees GM as competition if not the Bolt itself.That assumes he sees the Bolt as competition.
Yes, and it will be interesting to see how much the steel adds to the weight of the M3, which is the other part of the range equation. But, hey think how much weight will be saved by only having one screen.That's because of the high air resistance that Model X have. Model X 90D have 90 mpg city and 94 mpg highway.

I've quoted previously that Elon had mentioned the Model 3 was 20% lighter than Model S. So whatever weight the steel adds still makes it 20% lighter than Model S.Yes, and it will be interesting to see how much the steel adds to the weight of the M3, which is the other part of the range equation.

If memory serves, Elon mentioned 20% less volume at the 1st reveal.I've quoted previously that Elon had mentioned the Model 3 was 20% lighter than Model S. So whatever weight the steel adds still makes it 20% lighter than Model S.
Weight has a large effect on EPA city ratings but not nearly as much for the highway portion.Yes, and it will be interesting to see how much the steel adds to the weight of the M3, which is the other part of the range equation. But, hey think how much weight will be saved by only having one screen.

Tesla Motors (TSLA) Elon Reeve Musk on Q4 2015 Results - Earnings Call Transcript | Seeking AlphaYeah, I think the way to think of the customers is really that the Model 3, being a sedan, is about 20% lighter than – and actually quite a bit less complex to manufacture, than the Model S.
That will be the reason for increasing the battery capacity, since Musk tweeted itIt makes sense. It has to exceed the 238 mile Bolt. I can't imagine Tesla coming out with a Model 3 with less range.
