Out of curiosity, what's the point of a driver in something like this besides to have a human in the vehicle adding weight? Are they doing much? Serious & maybe very ignorant question. - Edit - For clarification, my reason for asking was due to this occurring in less than 1 second. I don't understand what the driver does as I'm assuming they have no gears to shift or turns to make.

I’d hazard you can’t get a world record without a human being in the car?

I’m no mechanical engineer, but I could definitely make something without a human inside of it go from 0-100 in less than a second.

Is this for some kind of [European?] [electric?] Formula SAE equivalent? I took part in formula SAE ~20 years ago! Some of the first and most rewarding engineering work I've done.

Yes, or maybe more accurately - we are the American equivalent of Formula SAE Germany. The German teams are significantly more advanced and better funded, with some of the teams running custom built electric inhub motors (something that's unheard of here in the US) I am currently on San Jose States Formula SAE team - we merged our electric and combustion teams last year to go all electric since it's where the stiffes…

Formula Student Germany has been leading the rules for the electric and driverless since their inception. There is a meeting every few years at the FSG event to align some rules for the different global student competitions. There was one this year again. (Source: I'm in the timekeeping team/organisation, to the driverless cars: please stop destroying our gear)

Fair question. But ultimately human sports are about humans. It’s just less exciting to watch robots compete (though I like it).

Very cool, but also kind of impressive that a Tesla manages this in ~2.5 seconds while doing all the other stuff a production car does. What time would a Tesla get if you stripped out all the extra weight? (seats, glass, electronics, roof, etc. etc.) Video here (900 MB download): https://polybox.ethz.ch/index.php/s/uKWFRcBjtl4foEy/download...

On a related note in the sports car community its been interesting to watch Acceleration stop being a mark of a performance car. There is even a lot of chatter around this being the end of the supercar segment since there are family wagons that can now do 2 second 0-60 runs. On top of that the speed is now too much for anyone to reasonably use off a drag strip or circuit. Now there is a huge emphasis on engagement, d…

>What time would a Tesla get if you striped out all the extra weight? (seats, glass, electronics, roof, etc. etc.) That's been done - you don't actually want to remove things like glass because the aerodynamic efficiency loss doesn't outweigh the weight removal. https://www.youtube.com/watch?v=ywvGbus3yxo

Neat! It looks like their 0-60 mph time was 1.37s.

Funnily enough, better than the previous world record holder.

Impressive but for reference, about half the acceleration of a Top Fuel dragster, which are also still getting faster.

Here's Brittany Force who holds the current records (fastest time, fastest speed):

https://www.nhra.com/news/2022/brittany-force-sets-national-...

0 to 338.43 mph in 3.665 seconds over 1000 feet. (The cars got too fast for 1,320 feet and have been racing 1000 feet since 2008.)

Acceleration was never really the top metric for super cars. It was more performance at high speeds, with high end cars like the Bugatti Chiron Supersport 300+ going up to 489 kmph (that is a lot in case you wonder). Part of the super car segment will go electric, that is for sure, but I do not see the end of the super car. Look at luxury watches. They are booming despite a Casio GShock with Multiband beating the shit out of them in terms of accuracy.

Thanks! I was about to ask how many Gs this translates too, my physics are a bit rusty...

In GNU units you can just do: $ units -t '100 kph / (.956s) / gravity' 2.9629132

TIL!
