Impressed if it Elon delivers.

[ExtraSlow]

If he delivers one, or of he can get to a reasonable production volume without massive quality issues?

I have faith that a handful will be built.

At $200k USD or more, pretty sure it will be low volume which is fine for Tesla.

[JRSC00LUDE]

Yawn.

Yawn.

I dunno if its yawning material.

This car will do 0-60mph in under 2 seconds. That's absolutely mental.

Serious question...

Do most people give a shit about how fast a car is?

When you say most people, you meant that 90% of cars out there are econo box and pick up trucks right?

I think most of Beyond cares, by the car enthusiast community is a tiny fraction of the driving public.

Ya, exactly.

I'm just not getting why Musk is making it a main selling point. Perhaps because he's got nothing else?

Lol wut? It's a sports car, it's built to go fast. How fast is what people have been waiting on for years now.

Acceleration is also one of the only things exciting about an all electric sports car. It's not like it's going to put some insane numbers up at the Nurburgring or anything.

What people? 1% of car buyers?

And unless they're going to a track, what is the point?

Dick measuring?

That's exactly what it is in sport car world. What's the point of LaFerrari, 458, Corvettes, Lambos and how many actually see track time? This isn't for general public like Model 3. It IS for 1%.

And the percentage of car buyers spending $200k on a car is much lower than 1%. But in order for someone to spend $200k on a car, there has to be something special about it... in this case, it's the acceleration.

It is crazy from a speed perspective for sure, it would be more exciting if a more legitimate automaker was doing it. The yawn is i'm just tired of the Tesla hype machine trotting out what is most likely another over-promised/under-delivered sizzle point to try and keep investor cashflow coming in.

I am interested in what kind of aero its going to have to be able to reliably execute those sub 2 second times, let alone the kind of tires it will need to be able to do that.

It needs to be able to get all that torque to the road somehow.

I feel like endless electric torque isn't going to be enough. Also sustaining torque and acceleration to get above 250+mph, I wonder if it has a gearbox?

[C4S]

At least, there is another Tesla look decent!

Still not the best looking sports car, but much better than Model S/X/3 ...

Aero plays almost no role in 0-60 times. It will play a big role at 250MPH though. The current Tesla can do 0-60 in 2.3 seconds, so it's not unreasonable to think they could improve on this... but I agree that 1.9 is going to be a harder challenge than Elon thinks. The figure of 7000+lbft of toque is the number I've been seeing and that's well in excess of what the tires could handle and the bigger problem will be breaking parts with that kind of force going through them.

Why would there be a gearbox?

[killramos]

Power and torque drops off precipitously with high speed with Teslas current motors. So to continue having enough power to accelerate through to 250+mph i figure they might need at least a second "gear" that switches at high speeds to lower the motor speed and maintain enough power. 250 mph is no joke.



Ignoring the absolute values because i don't know which model this is from, they are down to almost 50% peak horsepower by 130 mph all with half the torque of a Honda civic... Extrapolate this out to 250mph, its going to be tough to generate enough power to overcome drag. Now gear it down to a reasonable engine speed and that issue goes away. At least the way i see it.

But with the way Teslas "D" models work, now we are talking at least 2 gearboxes, even if they are only 2 speed. That's a lot of extra weight and mechanical complexity that Tesla isn't used to. Definitely an engineering challenge just like making any car reach those speeds. Current model S top speed is ~155mph, and I think there is a good reason for that.

Pros:
- Decent distance, could almost roadtrip it.
- Awesome speeds.


Cons:
- Tesla
- No steering wheel?!?

[tonytiger55]

Why do they keep doing the sports car. I never get it...

If they really want EV to sell. When will they for the love of god make a Civic, Corrola, Golf, Tata, Fiesta equivalent of it for the masses? Tesla Model 3.. is it here yet?
