In 5 years Tesla doesn't exist anymore...

You are indeed.
All electric cars still have to be geared so the high speeds of a spinning motor are converted to more usable speeds at the wheels.
They do this using a reduction gear transmission. It's typically only a single speed, but it's still "gearing", and dictates the final drive ratio of the transmission (just as a conventional differential does in a regular vehicle).
As the reduction gear converts fast motor speeds into slower road speeds, it also has the effect (again, like a regular gearbox and diff) of multiplying the motor's torque. So the 7400lb ft at a Tesla's wheels is a multiplied figure. To find the actual torque output at the motors you'd have to divide the 7400lb ft figure by whatever the final drive multiplies it by. And the size of the wheels/tyres, for that matter.
@Famine explained torque multiplication very well at some point but I can't find the post where he did so.

Those performance figures are just bat-🤬 ridiculous. I love it.

How do you figure?

Engine torque x gear ratio x final drive / wheel radius.*
*disregarding frictional losses.

Just a guess.
But other manufactures will be making electric cars cheaper and faster in terms of units per time period.
No need for a waiting list where you wait several months.
Just rock up to the dealer and plonk some cash down.
Would it make sense to develop an electric sportscar with a manual 6 or 7 or more/less gearbox (electronic through fly by wire system). Is it correct to say that such an electric sportscar could do with a smaller electric motor, using less batterypower?

I want to see this in a deep glossy black.
Adding a transmission would add losses to the system and since the input power would pretty much remain the same regardless of gear no point.
This video will explain it better.

From this angle the front reminds me of the ND Miata.

Wow, that’s actually kind of attractive.

Digging the exterior. Can’t say much about the interior until I have a more detailed look at it, but the steering wheel looks interesting.
Here’s to hoping that the windshield wiper is only a placeholder for something that fits better with the car’s styling!
Now, if only it doesn’t weigh a lot more than its competitors...

Am I the only one who's not upset about Roadster's windshield wiper?
Thanks a lot for the info. 👍

This thing blows my mind a bit. It's an exciting time to be alive!
It makes me wonder though, with other Supercar makers such as Lamborghini developing their own electric supercar, they were probably aiming for similar specs but with a price tag three to five times higher than the Tesla roadster. Will the exclusivity of a Lamborghini badge justify the enormous price hike?

It's all fun and games until you run out of government subsidies.

This reminds me of the SRT Tomahawk squished a bit, with the FT-1's old rear.

Now we’re talking!! 620Mile range is phenomenal. 1.9sec to 60 is insane. Excuse me, I mean “ludicrous”

Looks pretty. Very pretty. And incredibly quick.

Looks like the prototype cars form 90s early 2000 are hitting the market now.
But I dont understand the hype with the ev cars, it is way simpler and actually cheaper than a normal car. A normal car is two different systems combined, a intricate combustion engine that is made up of thousand of parts and a electrical control/management system.
Only the batteries are a tad expensive, but given time they will be cheaper and more effective.
It is funny when the sheeple masses think stuff like this is rocket science and that this tech is expensive. They see that the shell is pleasing and gladly pay more for less, haha.

Don't get why you're being so critical.
Battery technology has been questionable to say the least. Electric cars have been around since 1900, but gas just became a lot easier. It's all reemerging now because EVs are actually worth their salt in this day and age, and are getting to be seriously quick on top of that.
