This fan downforce enabled EV race car with slicks on it can do a 0-60 in 1.4 seconds.

I thinks this puts to rest the Musk claim of a 1.1 sec 0-60 Tesla Roadster if there still any people still hanging on to that fantasy.

They are claiming 1.9s? Where did you see 1.1?

He made the claim on twitter: https://twitter.com/elonmusk/status/1395474465794838528 ("Yes, with the SpaceX rocket thruster option package" is a reply to someone asking if 1.1 seconds is true).

That doesn't sound sarcastic at all. /s

I can see how Musk’s comment does sound sarcastic, but I think the Space X package isn’t generally being considered as a joke: https://www.motor1.com/news/508914/tesla-roadster-spacex-spe...

Whelp, no need for traction then :)

Not the OP.

You're right, it was always 1.9. They're still talking out of their backsides though. If the Rimac supercars can't do it without a fan to suck the car to the ground, Tesla sure can't.

Without a fan you just can't get the traction you'd need. There's no tyre on the planet which could grip that hard.

Additional detail - I suspect with a one foot rollout, on a VHT surface, on a hot day, in ideal conditions, they might be able to get down to a 1.95/1.93 sort of area. But on actual normal road surface, from stationary, with the tyres it comes with? Not a chance. I'd be astonished if they got to a 2.05. 1.90? Not a hope.

Source - knowing far too much about tyre/road interaction.

Model S Plaid has been clocked at < 2s by 3rd parties so I don't think 1.9 flat is that farfetched for the roadster.

You're not wrong, but not entirely right either.

They've not done it on a road surface from standing start. I know a reasonable amount about the tests that have been done to make those numbers, and Tesla require a foot rollout on VHT to get a 1.99/1.98 time. That's not the same as from standing on tarmac or concrete.

Rough rule of thumb is that starting from stopped on tarmac costs you about 25-.3s depending on conditions.
