Roadster 2023

[Daniel in SD]

Not good enough for sub 1 sec 0-60, as already explained to you several times with linked sources explaining why.

Not sure what you mean. Traction is traction. If you can brake at 6G then you can accelerate at 6G if you have enough power.
I suspect the only reason the McMurtry can't do it is that the motor doesn't make 1000hp until it's well over 60mph and if they fixed that (more torque at lower speeds) they would also need stronger axles.

They're not going use rocket fuel in an electric car (not to mention the nightmare for safety and inability to FIND the fuel for customers)

They'll make liquid hydrogen from water vapor in the air.

As a non physicist and non EE, I’m most interested in the transition from 1) active downforce at launch and 2) power needs at higher speeds.

Can anyone do the math based on current weight, estimated tire patch area and current tire traction properties, if you want to keep a constant 3Gs, for how long and how much extra downforce do you need? Not all the way to 250mph right? Also, what is the total amount of power area needed over that time to 250mph?

Does it really make sense to reconfigure the battery cell layout for double or triple max power when you know that the car can only use that much power for a few seconds?

I know ultracapacitors are bulky and heavy but does that amount of power still mean all batteries and no ultracapacitors?

The Plaid already goes 200mph speed and power requirements go up with the cube of speed. (250/200)^3= 1.95 times as much power to go 250mph. Of course the Roadster should be smaller so it would have less drag. 1000V architecture will double the power handling with the same wire thickness.
The Roadster makes no sense but that's kinda the point of hypercars.

You can't do either on street tires in a street legal car though. Not even with downforce, as previously explained to you because there's diminishing returns to adding weight to tires.... (I don't think even F1 gets up to 6 for that matter with insane aero and massive track-only tires)

They prob can't achieve 500 miles yet. Announce a product that will eventually get there. It'll be 5 yrs already since the announcement. Funny

It's almost 7 years already. They announced the new Roadster in November of 2017...

would think it would make a good DD? My goal is to get my money's worht and put 100k+ miles on it.....

That's my plan!

I think Teslas are the ultimate daily drivers. Garage queen cars with low miles that never had enough mileage to get parts updated: headlights, heater cores, door handles, 90kWh rev A packs, etc., make me sad.

I wonder how low a production volume Tesla can justify in keeping a line open continually?

That's my plan!

Sport Cup 2 tires that probably only last ~5000 miles on this car will be the only real annoyance to dailying it. I’m not going to DD mine, but I do plan a 50-50 split between it and my Model 3 (the 3 being the incognito/“beater” car).

Same. I'll probably sell the Plaid and pickup a used 3 performance to keep as a second car, if the Roadster ever comes out.

I had a car that came stock with the Cup tires. I just ran them into the ground and then put on PS4S. The damn cup tires heat cycled far before losing all tread.

Cup tires are best for the track, not the road, from all that I have read. Even if you drive only on dry days, the cup tires don't work well until heated up, while other more road oriented tires stick at normal temperatures. Mps4s are the way to go. Maybe pireli p zero.

This didn't age well lol. 2023
