Dual Motor Performance 0-60 times

[forkee]

You rock, thanks for posting! Seeing it pull .8 to .9 g's for the bulk of it was awesome. That's the real indicator of "feel". Would be cool to see the full reports on these runs to better understand the incline. Seems there was still a 2-3% grade? In any case, impressive.

Doing the hard work! Thanks so much!! What was your SOC? If you think of it later, it would be awesome to see the graphs of height/speed/acceleration for these launches. You're the first to carefully document the 0-60 AFAIK

Updated with graphs. Sorry it might not be in order. Uploads are wonky.

nice. what color is your car?

It's the standard black.

That's insane acceleration on all season tires. I wonder what people will hit with summer tread

 

[Johnabis]

I wonder what quarter mile would be? I'm guess mid to high 11's for the P. thinking the standard AWD Model 3 will be high 12's.

It's interesting to note how more flat the G-Force curve is on the P3D compared to the SDP100D:

SP100D gives you at that sharp shove and tapers off very
It looks like the P3D stays relatively constant from 0-35 and drops off slower after 35mph.

Based on the updated graphs (thanks @forkee !) The acceleration G forces are more similar to the ferrari in your example in that it comes up fast and stays ~.7-.9 G for about 2 sec until 30-40mph reached then falls between 40-60mph. Cool. Makes it a longer 'eyes open wide' experience!

Looks awesome and very promising, thanks for doing the tests!

Thanks for the update! Really good info. Can't wait to try the same tests with my lightweight aftermarket wheels and 275 width Michelin PS4S tires. Hoping for the 3.3sec Elon alluded to.

You have wheels picked out already?

Yep, bought them 6 months ago. Got the tires mounted yesterday.

@forkee Thank you for the awesome follow up. Btw, What was the state of charge for these runs?

 

[Mayhem]

TLDR on acceleration

P100D = more intense, shorter duration
3-P/D = less intense (1.4G vs 1.0G) but longer duration

Overall, no contest P100D @ 2.5s.

But bang/buck? I'm voting 3-P/D.

woops, forgot to include,

83%

didn't have time to get past 90%

I think there's a little more left in her yet! Maybe a 3.4 or possibly a 3.39 at 100% SOC and warm battery and flat surface (no onramp). Maybe a 3.2s with rollout for the car magazine times.

Woah Mr. Fancy Pants breaking out the formulas.

Yes, my explanation was over simplified, and I stand corrected.

Fancy pants is what some unwitting passengers might be if you punch it in a P3D. White interior owners beware.

Of these four, 3.55s run with 3.36% uphill seems like the most impressive. Average acceleration was a relatively smooth 0.770g - equivalent acceleration on flat ground would be 0.804g, which implies 3.40s may have been possible if not traction limited. Stickier tires may be needed to get there though.

Maybe I missed it but do you have a curve for the P3D or is the legend incorrect on this curve?

As an aside, if the P3D acceleration curve is bouncing up and down, would that suggest traction control is kicking in?

Thanks. 0-20 at repeatable 1.08 sec in those graphs. Supports YouTube video showing 55-75 mph in just over 1 sec. Traction control with electron motors must be incredibly fast/good to get that smooth an acceleration. ICE could never match that degree of traction control as the process is much slower. This will be the death of ICE.

Maybe on 1/4 mile drag strips ,..but gas cars are not going anywhere soon

Having driven a modified turbo that, when spooled, came close to the P3D level of acceleration at highway speeds, the exhilaration of that acceleration is addictive (though can lead to speeding tickets). The average driver, if given a chance to compare that feeling to 99.9% of ice cars on the road, will realize driving an EV is much more enjoyable than their previous cars. All the more reason to hope Tesla produces their 36K M3 by early next year.

That said, you are correct that the change to EV won’t be soon enough. ICE cars have been around since 1886. Given their 132 years, one hopes their remaining shelf life, except in limited applications, is less than 20 years.

That looks FUB! Can’t wait
