Here in Norway it's common for apartment buildings that have parking spots to have electric chargers outside and that seems to be working fine.

Your population density is minimal, though.

Not relevant. In fact, electric infrastructure is cheaper to deploy at high density than low.

Drag racing is meaningless? I totally get that you might not personally like it, but meaningless?

Rolling acceleration and track handling are more important than Drag racing. Bit fed up of 0-60 times being such an important feature. 50-70 more important, handling a bit more important again. And of course for most people build quality, running costs and environmental credentials.

The car also has record-setting 0-100mph times. And I'd argue for most uses, 0-45mph is more important, and all electric cars pretty much do awesome there.

Fair! That said, I do doubt those cars weigh close to the same. :)

Oh absolutely. That car is almost certainly a tube frame with a fiberglass shell.....was what I was going to say but then I looked into it and actually it's still sheet metal and weighs 3800 pounds. It has run a 6.987, and probably has north of 2,000 horsepower. Oh and it is street legal.

I'm confused. :( You think the hotrod will weigh the same as or more or less than the new roadster? I looked around and I couldn't find the roadster weight anywhere.

Probably not. Normal practical cars need space to put stuff that you want to bring with you. This car doesn't appear to have much of that kind of space, probably in lieu of batteries.

Don't bet on it. Battery density will keep increasing and price will keep decreasing. It might take 20 years, but it'll happen.

Well ya, but he specifically asked about the next gen Model 3.

Anybody know why Tesla didn't solve model 3 production scaling issues by subcontracting to someone who could do a "running start"? I would imagine a large portion of the car is relatively standard, being made of steel, mass produced components etc.

Because Tesla's real value is production scaling innovation itself.

Has the 8 second quarter mile been confirmed to be done in stock trim (i.e., no special tires or other modifications)? The reason I ask is because that is EXTREMELY impressive. I tune EFI systems on race cars as a hobby, and any car in the 8 second range usually needs to run slicks or drag radials to have enough traction. Even all wheel drive cars (GTRs, DSMs, EVOs, etc.) usually run 4 slicks once they get to that sp…

I'll be amazed, amazzzzed , if that car, stock, can create enough down force to keep itself on the road with stock tires, I don't care how good your TC is. Look at the size of the wing on the new Zr1 https://youtu.be/O_adY_b-aLQ?t=3m14s

Downforce is more than the wing. You see those giant diffusers in the back? Those work as venturi tunnels, creating a sucking force, sticking the car down.

As a matter of fact, F1 cars in the 70s-80s were using venturi tunnels that extended the entire length of the vehicle. This is impractical in a modern gasoline-powered car.

Theu were even getting so good with their aerodynamics that they were rumoured to be generating more downforce with ground effects than from wings.

In an electric car, you could do what they were doing back then.

What's even more amazing is that F or GM couldn't possibly do this. First mover advantage plus the allure of someone like Musk is what is needed. I know many bash him for spreading himself too thin among all his other ambitions but it gives him good will capital (which can translate to economic capital) when needed.

If they need more cash then they can just have another investor round. There's enough fan boys that would invest. I would prefer that Ford and GM not do this... I don't see how producing a $250,000 car will help the common folk, which is who Ford and GM serves. Tesla had first mover advantage with their Model 3 and now they are floundering. GM's Chevy Bolt is out producing and out selling the Model 3 despite first mo…

Ford does produce cars that are not for the "common folk". Same with Mercedes, BMW, etc.

All nice and good. We see the EV revolution in front of our eyes. But nobody speaks about the EV infrastructure.

Tesla also announced the semi truck "Megacharger." 400 mile range (at less than 2kWh/mile) in 30 minutes. That's about 1.5MW. One and a half Megawatts. Made feasible by using a Tesla stationary battery to buffer the load to the grid and/or solar panels. And a flat 7 cents per kilowatt-hour.

I guess I'll be eating my hat then. I'm pretty amazed that you'll be able to keep it planted that fast around corners, but if you can, this will be an incredibly fun (or maybe very boring!) car to drive.
