GT craving

[Ghost Ryder]

I want to see a race between a GT and 4x starting from a roll from 70+. What will that look like?

A 4X can look rather decent:

From the side, they both look alike, its the front that makes the biggest difference. The aggressive front intake really stands out over the mustache of the non GT.

I guess if you were looking at the change, you would have to consider if you are often racing a Premium to 60 where you need a GT. I worried that we messed up ordering a Premium instead of a GTPE, but after driving the Premium I can't see the point of spending the extra money. We aren't racing people on public streets because that's stupid, and the price increase to go from having a car that is faster than 95% of the vehicles on public roads to being faster than 96% didn't make sense to us for the range hit.

Again, it's always a personal choice in the end. You just have to weigh the pros/cons. For our usage the GT or GTPE have more cons than pros. Since I was a kid we have been involved in most kinds of motorsports, drag racing, autocross, etc, but have no interest in such things on public roads and if drag racing in a street class, it is typically bracket racing so consistency means more than top end speed. The Premium will be more consistent run to run than the GT due to the power cut.

Now if the GTPE was something like $3k more than the Premium, I would consider it for the magneride more than anything. Although we intend to road trip the car and it would still be a back and forth on losing some range.

The reason I went with the GTPE was:
1) I liked the front end a lot better
2) I wanted the Magnaride suspension do to multiple report of bouncy ride in the GT
3) Like the wheels better
4) nicer seats and interior.
4) the acceleration difference (before I found out about the 5 sec rule and the power reduction above 70)

I think when I bought it, the difference between a GT and a Premium was like 10k. But I'm assuming that when I sell the car eventually, I'll be able to recoup some of the difference, and hence the difference would only be around 5k. So for 5k difference, I felt the Upgrades was worth it.

None of this wrong except the never catch up part. The 4X hits 110 in 15.x seconds, the GT in 17.x seconds. It’ll get swallowed up on the big end, sure it’s after the 1/4 but it’ll happen. The GTs seem to hit 87-89mph in the 1/8th vs 82-83mph for the 4X, but, in the span of the next 1/8th mile (660ft) it gets to 101-103 depending on source vs 101-103+ for the 4X. And it gets worse for the GT after that. 4X gets to terminal velocity (113) in about 17 seconds and the Michigan State Police clocked the GT at 50+ seconds to 124 max speed. So it seems to be a see-saw battle if running them all the way out.

You’re still missing important details.

Even using that one data point from Car and Driver, the GT is bus lengths ahead at 100 mph.

Distance over time wins drag races…….NOT speed over time.

And due to the significantly non-linear nature if the GT acceleration, there’s no way a premium would catch up before hitting its top speed.

Police version of the Gt in cold weather and extra weight and drag? Come on……. You know better than to use that garbage as real data.

If you want to see a top speed run of a Gt in GOOD conditions….. it’s posted on the Facebook page.

I posted screen shots here:

73mph to 110 mph took about 6 seconds.

73 to 124 mph was 13 seconds.

Again….. the premium has ZERO chance when a GT is full charge and in good weather.

I was all in on the other number 4. ??

I got the GT-PE mostly for the suspension and bigger brakes. I was also bamboozled by Ford’s 0-60 claims and hoping there was a way around the 5 second limit after @0t60-3.5 posted his findings. No luck there since the biggest hurdle (and not the only one) is the main bus bars being under-sized. ??

It’s the same posts over and over. I get it. The GT is dogshit after 80mph in any condition other than perfect planet alignment and 70+ degrees. The 4X seems to be fairly impervious to temps/SOCs within the normal realm of EV expectations. In time to speed, the 4X comes out quicker once you get past 100mph.

Also, I posted dragy runs in the thread by @tesla2mme to compare with his GT runs at the airstrip. Not only were they quicker from the various speeds but the 4X used less distance as well. So, yeah.

I’ve never disputed a 4X gets to the 1/4 faster than a GT, I don’t think anyone has. But it is traveling faster at the 1/4 and all the way to 113mph. For whatever that’s worth. ??‍

to be very fair, your runs had a significant downward slope. With an upward slope my time slowed while distance increased quite a bit.

Run with -0.5% downward slope was 6.52 seconds and 829 feet
Run with +0.4% slope was 6.84 seconds and took 873.8 feet:

conclusion is that downward slope will be a big factor for that speed run.

your runs, IIRC, occurred with full percentage+ of downward grades not in the tenths of percentages. That isn’t insignificant data… how much, we won’t know, until someone takes me up on my offer to run side by side with me. It would be fun !!!

Correct, downward slope is a factor, but it’s small when you’re around -2-3%, I’ve seen a 2-3 tenth ET difference at most in my SS between 0 and -3 degrees. Like I said in my other comment, I’ll try to get runs at the location where the slope is within the valid run tolerance.

Perfect.

Then until we get an exact time from a fully charged GT, compare them to the times from this video:

When the premium can go 73-110 in 6 seconds…… we can talk.

Just be sure to repeat the run back to back and see which car is able to consistently repeat whatever number they get without grey bar jail.

 

[Pushrods&Capacitors]

Ah yes, the infamous Facebook ringer. Let me know when you or anyone else duplicates that run. This is a 70-100 run where the slope was close to the -1% valid threshold. I know from experience that 4.9 would turn to about 8 seconds if stretched from 70-100 to 70-110mph because after 105 the digits flip more deliberately for certain.

Well, I’ve done repeated runs in 90+F in our 4X and the difference is minuscule. 3-4 hot lap type runs stay within 2-3 tenths.

That was my point really. I don't know why the discussion has gone down to drag racing as that's probably not a first priority for most any MME owner, but the GT/GTPE seems to have a gray bar issue not just for the 5 second rule, but repeated usage. It doesn't sound like it's quite as easy to get a Premium in that same position (although it is possible I am sure).

So if you were actually at a drag strip, not just test and tune but actually in a class race, you don't always have 30 minutes between runs to let the gray bars drop off. In bracket racing I would take the consistent car that can do it over and over instead of the faster car that if we got down to the semi finals or finals may have to run immediately after the last pass.

Again, if drag racing was your priority for these cars, which it wouldn't be for me, but just talking about the for-instances.

Having owned a Premium then GTPE then back to a Premium... I'd say only get the GTPE for a couple of reasons:

1) Vastly better (and more comfortable) seats.
2) Better looking wheels, larger/summer tires, and beefier brakes.
3) Slightly improved interior.
4) Insane acceleration from 0 to 60.
5) Improved suspension in Unbridled mode but terrible in Whisper + Engaged.

For $12K extra I don't think it is personally worth it. The major negative is the range (you lose easily 40-50 miles) and the poor/bouncy suspension in non-Unbridled mode.


I'd want Ford to fix the track mode (Unbridled Extend) and improve efficiency of their motors + inverters (maybe 800V) before I'd buy another GT PE.
