Isn't it great that Tesla is producing EVs that inspire the same sort of absurd bench racing arguments as all the other performance automotive forums?

Dude, seriously, give up now... you look ridiculous.
Dude seriously...,the other guy posted sources and all you come up with is "butt feel"-basically.Why is that, exactly? The guy is quoting Car & Driver as the bible, doesn't own a Tesla, and believes a 10 y/o IS350 is quicker to 30 than a new AWD 70D. Would you take that wager at the strip?
... thus debunking the idea EVs are misunderstood because they may do the same 0-60 but they're magically SUPER fast ...
There is no way in hell that going from 50 to 70 mph in a 340i manual takes 6.5 second.
In a manual-transmission car, we usually start acceleration runs with a wheel-spinning launch. It's simple: The engine is revved to a high rate, and the clutch is abruptly engaged. No power shifting or speed shifting is allowed, so we shift rapidly but by the everyday method of disengaging the clutch and lifting off the gas. With a great variety of vehicles, it's not always readily apparent which is the optimal launch technique, but we do our utmost to extract every ounce of speed from each one. Often we try launching the cars at varying rpm while hoping nothing breaks.
On most cars, we upshift at the engine's redline, but on torquey engines, we experiment with short shifting as well. With automatics, we try shifting manually if the transmission upshifts short of the redline.
The technique used with automatic transmissions is called brake torquing. With the left foot pressed securely on the brake, holding the car in place, the right foot squeezes down on the accelerator and the car is launched by releasing the brake pedal. That almost always results in quicker times than just flooring the car from a standstill.
Since most owners will seldom subject their cars to brutal launch techniques, we also perform what we call a street-start acceleration test from 5 to 60 mph. While rolling with the car in gear, we floor the accelerator at 5 mph and shift quickly at the optimal shift point.
We also perform two acceleration tests, from 30 to 50 mph and from 50 to 70, in a vehicle's highest gear. In vehicles with manual transmissions, this test measures how well a car's gearing matches the torque curve of its engine. With automatics, the test begins in top gear and then the car downshifts automatically under hard acceleration. This provides information about transmission responsiveness and actual passing times, but any comparison of results between manuals and automatics is meaningless.
Man, what a mess of a thread and in no small part to @JonathanD; please keep posting, mate. We all need a laugh; please hug your Tesla tonight and buy it flowers. Maybe your Tesla will hug back this time.
The seemingly most salient points here:
1. ICE cars in this price range have torque, too. It isn't a zero-sum game; half-a-second delays don't negate the literal existence of hundreds of ft-lb of torque. @Knightshade is quite right.
Fair reading, thanks.But for those who do drive for maximum acceleration, the EV vs ICE differences are not so gaping, I think. It's just a lot easier in an EV to "max out".
Glad I could entertain you. The discussion was about EVs being quicker off the line 0-30. The assertion was made, based upon Car & Driver articles, presumably from different issues, different drivers, and different environments, that an IS350 was quicker to 30 than an AWD EV with a similar 0-60 time. I proceeded to disagree with that, and still do.
Fair reading, thanks.
I have to say though, that the ICE requirements read to me as drag racing and taking the car to the track. If I cared about this issue at all for my actual driving, I would be thinking of a passing situation on a climb.
Right... everyone else is looking at instrumented data but none of that matters because your ass dyno is more accurate.
We get it. You "win". Good day to you sir!
One should never compare EV 0-60 numbers with ICE 0-60 numbers (those in specs)
Real test for ICE vehicle 0-xx acceleration is in Drive, foot on the brake pedal
and LIKELY engine killed due to start-stop. We can exclude start-stop but we
will not include sport gear nor holding two pedals or doing anything besides waiting
at the red light, foot on the brake pedal. No sport modes, no other funky selections.
Most cars are sluggish when kept at idle rpm at intersection launch in "default mode".
Preparing for some ultra-blabla stuff is not realistic. ICE vehicles are not
banged "pedal-to-the-metal" all day long. They just don't last that way.
EV's can be banged forever. Until you run out of juice.
Model 3 drivetrain is a new drivetrain. And it is NOT performance oriented. Price,
reliability and efficiency is above performance.
but I've never heard of an ICE car having the computer stop it from being abused if that's what the owner wants to do with it.
My ass dyno, and physics. We know the torque curves from both cars. IS needs to get to 5 or 6k RPM to get to peak power. It has an automatic transmission. One has AWD, one does not. The cards are heavily stacked against the Lexus in a quick hop to 30mph, but you can believe whatever you like.

Apparently you don't know the torque curves...
Peak torque (277 ft-lbs) is at 4800 rpms. But it's already over 200 at 1700 rpms and over 250 by 2900
Yes and peak torque from an electric motor is available at near zero RPMs. This is why the race to thirty heavily favors an electric motor.
