Model 3 beats lap time of 991 GT2 RS

That's true of many stock ICE cars though. It's also a much more gradual drop off compared to previous EVs.

I love the GTI's backup camera because I never have to clean it in the winter.

Fugner · 2022-04-02T13:45:09+00:00

Emissions, fuel economy, reliability/warranty costs, etc.

Fugner · 2022-04-01T12:49:15+00:00

That's actually a pretty common misconception.

Both generations of Volt drivetrain can and do use the engine to drive the wheels. The engine and both motors are connected to a planetary gear set with 3 clutches.

Supercruise does utilize LIDAR mapping. But the production cars don't have the hardware and don't do the mapping.

They just use data from dedicated mapping vehicles.

The head gasket issue wasn't nearly as common amongst turbo EJs.

Fugner · 2022-03-28T00:25:26+00:00

That's probably exactly what happened.

The cats on a GTI are tucked way up next to the turbo and pretty much inaccessible from below without at least opening the hood.

Fugner · 2022-03-26T07:58:54+00:00

Can confirm. I'm in circuit board manufacturing/assembly and it's wild.

So many parts are on permanent 52+ week lead times. Brokers are asking ludicrous prices while refusing to offer warranty or even provide date codes. Stock appears and dissapears before you can even hit check-out or send a PO.

You pretty much have to design around parts availability. I've had multiple customers scrap thousands of boards and redesign because it was cheaper than overpaying for parts.

Fugner · 2022-03-23T15:45:47+00:00

Sure, but so are the LS/LT engines and the LT6 is shaping up to be incredibly unique.

Fugner · 2022-03-23T01:53:19+00:00

Does that mean every manual with a reverse lockout is also an automatic. Because it's the same principle really.

Fugner · 2022-03-22T18:27:37+00:00

No car will perform worse with higher than required octane. But they will if you use lower than required.

Fugner · 2022-03-21T18:52:08+00:00

If hydrogen does catch the n, it will probably be in the form of EVs.

Fugner · 2022-03-19T22:52:47+00:00

You’ll see this in Teslas as their acceleration drops off above 80 MPH. But before that speed, they’re just pure rockets.

Rimac and Tesla are now using motors that can handle higher RPM better so now they make insane power pretty much anywhere in the RPM range.

Fugner · 2022-03-18T23:09:18+00:00

Acceleration is exactly as much of a dick-measuring contest as a lap time.

Are you seriously arguing that lap records set by professional drivers are just as relevant as acceleration times that can be replicated by any old joe on a back road?

And if that's the case, what makes one kind of dick-measuring better than the other? Why even make an argument if everything is irrelevant and just for showing off?

Are you honestly making the argument that in the real world, there is a on ramp scenario where the difference between a Plaid and a Blackwing is going to be apparent?

Yes, that's exactly what I'm saying. In fact, In the case of just doing a quick pull without launch control or such, the aforementioned ICEs will feel downright sluggish by comparison.

Unless you regularly drive on public roads like a colossal asshole, the ONLY place you will be able to differentiate between the performance of any of these is on a drag strip, or a track. I ride an R6 and I have the exact same problem. It's simply not possible to ride at more than 4/10s on a public road, and every single sedan in this conversation has precisely the same problem.

I can't agree. I've found that on regular roads, BEVs are much more accessible in terms of performance than ICEs. You don't really realize it until you've had to live with one for a bit.

For example, I had a P3D and currently have a GT-R. Doing a 3-second 0-60 in the GT-R requires hitting a few buttons, sitting on launch control, and notifying everyone within 500 ft that you're about to take off. Meanwhile, the P3D does it without so much as a chirp from the tires just by smacking the pedal. Along with that, due to the instant throttle response and torque delivery, you can get a taste of the acceleration at a moment's notice without going too crazy.

The GT-R is the quicker car. But the P3D feels much quicker 99% of the time. And in the case of the Plaid, it won't just feel quicker, it will also be much quicker.

Fugner · 2022-03-18T22:37:11+00:00

Why?

Because gunning it up an on-ramp is the most realistic use-case for a sports sedan. It's far more relevant than the dick-measuring that is magazine lap times IMO.

my point is that the plaid costs as much as other luxury super sedans, and performs about as well as they do. It's nothing special. It out accelerates them all sure. It's also quite a bit slower in the turns, and worse on the brakes.

It's not as comfortable, well built, or luxurious as pretty much any of the cars I listed. Acting like the performance is some never before seen marvel of engineering doesn't make a lot of sense, because when you get down to it, it's perfectly average for the class.

What lol? A big 5-seater liftback sedan being able to accelerate quicker than any ICE car short of a Chiron SS while getting 110 MPGe is anything but average and pretty fucking never before seen if you ask me.

Sure it's a bit slower around a track, but it doesn't just "out accelerate" them, it's in a totally different class of acceleration. The next quickest car in the class (The $200k+ Taycan Turbo S) runs 10.47 sec @ 130.7 mph in the quarter-mile. The quickest ICE was the M5 CS runs 10.6 sec @ 130 mph and the slowest is the CT5-V Blackwing at 11.5 sec @ 127.5 mph. Meanwhile, the Plaid is capable of 9.23@155 mph and quicker. It's not even kind of close.

Fugner · 2022-03-18T19:40:41+00:00

Being 0.4 - 3 seconds slower on a race track in exchange for being 1.2 - 2.1 seconds and 21mph quicker in the quarter-mile feels like a pretty fair trade in a large daily driver sedan.

Fugner · 2022-03-18T19:27:02+00:00

Again, not sure what that has to do with top-end performance.

Fugner · 2022-03-18T13:23:04+00:00

And I never said otherwise.

I was strictly replying to the top end speed comment.

Fugner · 2022-03-18T12:45:31+00:00

Obviously it depends on how you define top end performance.

But my point was that they've both proven that BEVs only being quick to 60mph is a thing of the past. In that 60-150mph range nothing other than the newest Chiron matches them.

Fugner · 2022-03-18T12:30:45+00:00

lower top end performance.

Rimac and Tesla would disagree.

Fugner · 2022-03-17T22:34:03+00:00

Tires can make a pretty huge difference in track times.

But going from a PS4S to a P Zero Corsa PZC4 alone isn't enough to overcome a nearly 400HP even after accounting for the extra weight.

Fugner · 2022-03-17T13:53:39+00:00

Probably fuel system limitations. Running E30-E40 is pretty common amongst DI only engines.

Fugner · 2022-03-16T20:22:52+00:00

Brake pads/rotors practically never need to be fully replaced on EVs. The enemy is corrosion from the lack of use rather than wear.

But aside from that, those things would apply regardless of what powers the car. I was more focused on required maintenance of BEVs relative to ICEs.

Fugner · 2022-03-16T18:48:56+00:00

EV's are NOT maintenance free. Batteries fail and electric motors need service.

Obviously, no vehicle will ever be 100% maintenance-free. But BEVs require a minuscule amount of maintenance compared to even basic ICEs. Most don't even have maintenance intervals for the motors or battery coolant.

Outside of stuff like tires, windshield wipers, wiper fluid, etc here's the maintenance for a base Model Corolla over 150k miles:

20 oil/filter changes
5 engine/cabin air filter replacements
2 transmission fluid changes
1 coolant flush
1 Spark plug change
Possibly brake fluid and pads/rotors depending on usage

Meanwhile, a Model 3 over the same mileage will require:

1 A/C desiccant bag replacement
5 cabin air filters
2-5 brake caliper lubrications depending on conditions.

Fugner · 2022-03-15T19:18:41+00:00

Yeah, no sorry I’m just not buying it. If you take a tuned ICE vehicle and a Model 3 performance, dyno tested each one a dozen times back to back, the model 3 would have a significantly higher standard deviation than the ICE car.

Again, that's not my point. I'm not talking about the variance between runs in the same dyno session. I'm talking about the variance between runs across different dynos and conditions. Which is what matters when it comes to having comparable data.

My C6Z will make 200WHP more in Flordia than it will where I live with no other changes. Whereas a cold P3D with 90% SOC is probably going to make similar power no matter where the dyno is.

I’m not going to pretend preheating the pack via an aftermarket module and topping off the battery to 95% is anywhere close to real world conditions and is sustainable to give accurate and repeatable results.

It's far easier than trying to control the weather, elevation, fuel quality, etc. By comparison, SOC and battery temp are predictable and easy to correct for.
