Keith, imma need some parts out of your Tesla, K???

Can you imagine a belly-tank style E racer? So much awesome!

Like this? 

I'm guessing there's a bunch more that were ready to go this year and last but never got the chance.

I want to see someone apply this tech to a Bonneville car. Fastest standing mile? Something...

Dude.... that would be amazing. Traction on the salt will be a problem and the amount of juice you'll need. But still amazing to watch.

Do it at the Texas Mile, no traction problem.

If you go out to your garage and the tesla body is on block missing motors and batteries I know nothing about it.

WOW - impressive.  The squat when they kick the fans on is cool.

Depending on which website you believe, a top fuel dragster does 0-60 anywhere from 0.8 to 0.4 seconds.  Either way, this car is creeping up on that number.

A suction car on the Bonneville Salt flats would look like a snow making machine....

No, it would be quick.  Electric cars need a LOT of juice for fast.  I doubt that belly tank car pictured above would be faster at Bonneville than a two stroke single.

The 0-60 party trick is getting old.  It is cool but IDK about it any more.  
 

If they could now work more on the opposite of this and make batteries charge as fast as they can pull electricity out of them to do these insanely fast 0-60 runs.

So the driver, with suit and helmet, weighed 88 pounds? Was she under 4' tall?

its so fast it looks fake, like its strait out of a video game, its crazy. Also it apparently only makes 322 hp, and the top speed is 77 mph, doubt the quarter mile will be that quick.

100% due to gearing (or whatever the equivalent is in EV.) The courses these run are not large.

They need to take that thing to a long straightaway somewhere and figure out the top speed. 

It actually might not be capable of going much faster than that. That looks to be a (modified?) Formula Student (Formula SAE) Electric car, which are designed around dynamic events that don't get much over 60mph anyway.

You might be right.  I didn't watch this video because I think it's the same one from about a year ago.  If it is they are using hub motors at all four corners which means no or limited gear reduction so they are limited by motor RPM and tire size.

Okay, zero to 60 in that amount of time almost seems anti-climatic - especially if you blinked laugh. Either way, quite impressive.

We already have that in lithium titanate batteries.  Charge/discharge rates can be 10C or more so a 100 Ah cell can pump out 1000A (for a short time)  and can recharge almost as quickly.

I bet they could take this into one of the warehouses or stadiums and also get the fastest indoor speed record. I believe that's still 102 mph by a Taycan as contained within a building with the 130 mph Formula E value in a sperate category since it was just while passing through a building.

So this is basically an acceleration-optimized Formula Student car. In the comments on another site, someone posted this in-car video from their "slalom" run with one of these cars. And note that the onboard G meter only shows about half the acceleration of the one that just set the record.

Tom1200, we found your electric autocrosser.

How can you not love that..............that would be totally awesome to drive. It appears to have A-mod level performance.

Crikey! That made my neck hurt and got my heart rate up just watching it!

Listening to it also made me wonder once again if we're someday going to associate the sound of electric motors working hard with exciting performance the same way we do now with all of the noises that internal combustion engines make.  It's not as visceral so maybe not.

I already do associate that sound with performance :) And when it's intense enough, you can almost feel it on the surface of your skin. Someone who grows up with this performance- like the students who built these cars - will likely have very different associations for ICE engines.

In reply to Keith Tanner :

that thought has crossed my mind. Would the generation that grows up with electric race cars find that driving more pure? In addition to no noise they wouldn't have to adapt their driving to an engine's characteristics and the big vibrations would come from the chassis (unless the motor is out of whack).

I know that my little nephews - who grew up with Power Wheels - find it totally normal that my car runs off batteries. 

How much does being able to hear the tires clearly affect your ability to use them to their potential, I wonder?
