Cars, it's electric! Do Do Do

This is crazy how badly the Sapphire destroys the 170, even on street slicks. That's the thing about the electrics, no skill needed, just point and shoot. Sad. 😁

In a straight line, that’s the only metric anyone focuses on. Maybe when these things start weighing less 5500lbs, get some type of decent range, and recharging time under 3min, I can consider getting one to use like an actual car.

Agreed in most cases, but the 170 was designed for that. Not sure it would win many road races. 😁

I didn’t watch the whole thing but isn’t the 170 auto with a launch control? Pretty much point and shoot there too

no, not even close. No RWD street ICE car with enough power to run 9s is point and shoot. Traction is everything. Im not trying to knock the hellcat, I think its cool and its cool that dodge builds such things.....but it also weighs 4300lbs, which is really f'ing heavy....It has drag radials on it, but they are relatively small given the cars weight and factory suspension. You would really have to tune that car thru every bit of the first probably 2-300ft of the run based on track conditions. Additionally, nobody has really been running the numbers dodge claim...8.9s @150....if you just do the math on those #s....8.90s, 150mph, 4300lb car....you should need 1150-1200hp. I have never seen any of these cars running over 145mph.

Meantime that Lucid makes all its torque at 0 rpm, awd, traction control....no brainer.

That said....As impressive as the Lucid, plaid, etc are as street cars running low 9s and even high 8s.....Electric drag racings cars are pretty unimpressive.....Fastest dragster to date has only gone a 7.5, and the fastest electric door car has run a 7.98.....Seems to be a real brick wall in terms of power they are running into.

Got it. But there is still launch control and an auto. So it’s somewhat easier than no launch control and a manual…right?
My point was, the dodge still makes it much easier to do low 9s.

The lucid is just a different category IMO. Instant battery torque and traction.

Well you can use traction control, but if it activates, it will kill the cars 1/4mi time.....Like it might keep it from blowing the tires off the car, but it will kill a good time/launch. So at a track, you would most likely turn it off. Dodge made it "simplified" but you still need to do a burnout, heat the tires....maybe use the transbrake if the traction is good enough and will handle a higher rpm launch.....Then if its spinning, you have to start playing around....Tire pressure, launch rpm, maybe suspension adjustment, etc. Its probably as good as a 9 sec factory, street legal drag car can be. Just would be nice if it wasnt so dam heavy. For example, if you take a 3000lb fox body mustang....you can run 9s with 500hp as opposed to over 1000hp needed for a demon.

I can't find the velocity curve - are they hitting their top speed and that's all they got cause no trans?

I mean at the end of the day, you need power, massive amounts of it.....6 sec cars usually make 2-3000hp....5 sec cars are usually making 4000+...then it starts getting crazy....4sec top fuel cars making 10-12,000 hp....thats like 7500+kw....if the system was 400 volts....wouldnt the amps be some ABSURD number...like in the 20,000 range? Plus an electric drag car would always be heavier than its fuel counterpart. @Santapez you know way more about electricity than I do....that sounds like a pretty big issue to solve

It is an area under the curve problem.
Area under the velocity X time curve is displacement. (Which you know)

Plaid has a top speed of 200ish, so it runs out of torque to maintain acceleration - which to your point is horsepower (or watts)

Id just like to see the curve vs some ice cars esp RWD

I got a B in electricity.

Figure 800V as that's what Porsche I think is using.
7,500,000W/800V=9,375A

i'm not so sure about the weight thing now - batteries are sized in amp-hours -
somewhere I read they can get 9 runs before discharge becomes a factor.
does that mean they could cut the battery to 1/10 its size for 1 run?

Yikes. Glad she's ok.

Whatever she wants!
Lucid air?

She's very undecided. Doesn't want another model y because it's the only Tesla that hasn't been updated yet. Doesn't have any interest in the other models. I think we might go with rivian. They are running lease deals on the 2024 r1t, and friends and family discounts are pretty easy to come by on Reddit. It'll give us 3 years for her to decide what the next car will be 🤣.
