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.)

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.

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

Funnily enough, better than the previous world record holder.

Not exactly -- the previous record was for 1 to 100, not 1 to 60.

That's 0-100kph (0-62mph).

What's the math on the weight vs the affect of drag at that level? Aero doesn't come much into play in 0-60.

"Drag karts" are becoming a thing and they do just fine

There's still lots of extra weight on that Tesla! Take a look at this one lol:

I'm pretty sure a Tesla spends most of its 2.5 seconds traction limited. Ie. if you could fit gearwheels and drive on a toothed road, I think a stock tesla could accelerate faster.

Or burn, or cost three times the price! Most components used in Teslas are not made to run so intensively, wether it is the wheels, the motors, the battery, the brakes, ... they most likely limit the acceleration to prevent bad things.

Still wouldn't get close (in the performance sense, where the effort to time gained is logarithmic in nature).

This car weighs 309 lbs. The batteries alone in a Model S weight 1200 lbs.

True, but this car has low 300s HP, no torque mentioned that I saw. The Tesla is over 1K HP and torques. The Teslas, for road cars, are pretty stunning for acceleration. Agreed that it's not going to reach this level of 0-100 performance, but it sounds like it can get shockingly close.

I've driven Porsches on the track, and the Tesla Model S Ludicrous loaner I had for a few days is startlingly fast. Fast enough that I decided I was glad I didn't get one.

This thing has a power to weight ratio of close to 2 HP per kg. That is beyond insane, and if they didn't have active suction that is essentially doubling the grip, this thing would just be fast at converting rubber into smoke.

Just to put in perspective how ridiculous it is, the equivalent would be if the Tesla was close to 5000 HP and could produce 5000 lbs of suction downforce at standstill.

Uh, Telsa plaid does 0-60 in 1.9 seconds

The 1.99* that Tesla reports is a 0-60mph on a VHT prepped surface (glue basically) with one foot of rollout deleted.

This is 0-100kph (0-62.1mph) on standard tarmac without any rollout which a plaid does in about 2.5 seconds.
