My GT Performance Edition (GTPE) first track launch with videos, timeslip! 0-60 in 4.12s, 1/4 mile in 12.657 @ 100.02 mph

[harrysiii]

thank you for your bravery! This forum is a tough crowd.

Have you tried the launch method of 1PD off, holding brakes while pressing accelerator, then releasing brakes and jamming accelerator for launch?

At least I think that’s an optimal launch method for EVs.

and have you tried in unbridled extend? Consensus seems to be that extend slows down the vehicle.

only other ways to get faster would be drop passenger, skip meals, pull out anything heavy…

I did not try extend, or with 1 pedal off. Extend does turn Regen and 1 pedal off though. Will do more testing in the next few days, including 50-70.

I also had music and HVAC off.

This is the best I just got. 2 people in the car. 80% SOC. 70° outside and after a few other runs. Also brake stand.

Traction off, unbridled.

And just to compare, there are a lot of MYPs out there that aren’t running this quick. Here is one of them. And I noticed most of them 0-30 in the 1.80 range whereas you got a 1.69 with a passenger. You’ll hit the 3.5s without the extra weight.

And to be clear, when I say 3.5s I’m talking the 1ft roll out time, because like it or not that is the industry standard and what Ford states it uses as well.

Yeah but how do you know those slow model Ys don’t have like 4-5 boxes of Elon Musk biographies in the back. Seriously though wouldn’t extra weight in the car be expected if they’re slowish? Like we know what the Y runs now in pretty normal conditions.

60' is good for a vehicle this heavy.
As with any EV, the consistency is there.
This is the way you are supposed to figure things out.
Start with what you have to determine a baseline. Make
one change at a time to find out what works and what doesn't.
As far as tire pressure, run as high as you can get away with without
spinning the tires. This way you will have lower rolling resistance at higher
speeds.
Adding weight to front end may help with traction but at a cost of HP.
Not sure if it is similar with cars, but, when racing motorcycles, we used to
figure that 10 lbs. added or subtracted equaled One Horsepower. I have seen
posts where someone has lowered their MME ( Properly ) about an inch all
the way around. Perhaps just lowering the front first to see what effect it has.
This may end up being an overall plus to lower the front tire pressure ( or stickier tires )
I have the Runt ( Standard battery, RWD ) so not aware of the additional
features on the GT or GTP.
As far as charge goes, Charge it as high as possible prior to arriving at the
track. Then, scout around for outlets. When racing my Electric motorcycles,
I use 1%~2% per pass. Unless you are just doing laps, you should have time to
recoup at least a little charge for consistency. The track here in Vegas has
some unpopulated 120V and 240V outlets that are accessible ( at least for my motorcycle )
near the concession area.
Congratulations and Good Luck

How about Ford just fixes the problem and builds me a car that meets their published times without me having to put on lowering springs and trash my range with low pressures.

My tires were also at 41 from the dealer but car states they should be at 39. I'll try 39 too.

And I wasn't on a prepped track. Planning on the track next Wednesday o Friday when they're open.

Well, we know they’re packed full of hubris, but that’s hard to convert to lbs. And maybe they have extra weight, or not, my point is that for every one out there running 3.5 or 3.6 there’s one running 3.8-4.0. And after literally a handful of runs there’s a GTPE in the 3.6s and prob soon to be 3.5s. Hurdle #1 for all
of the butt hurt 0-60s guys is now cleared. Now, onto that 1/4 mile trap speed.

Cool. Run your tires at the highest psi you can barring wheelspin. This will maximize trap speed. On a prepped track surface you may be able to get away with higher than the 41 you were at today. This is contrary to what many old timers will tell you but that is how you do it with AWD because there’s usually no traction issue. Source:

Someone just posted this…

X233, base GT with 72% charge.

“The GT really slows down after 80 mph or so. I ran it in Unbridled mode.
My second run was against a modified Grand National. Same deal, left it sitting but got walked down. Unbridled extend mode, slowest run.
Last run was against a modified newer GTI. Unbridled mode, no extend.”

Prepared to get decimated by everything from a roll or after 1/8 mile… GT’s have 0 top end until Ford changes something.

0-60 will be almost as good as MYP but then MYP will take off like a rocket as it’s about 6 mph faster in 1/8 and 13-15 mph faster in 1/4 (huuuuge difference)

 

[GT500R]

And just your daily reminder, when the GTPE post 70 or whatever mph issue gets sorted out, it should run with these guys ET-wise. Mph won’t get quite as high. But neither does a Model Y.



Good stuff, that. 11.9-12.1 spread and they all trap 115-118mph range.

Neither does a Model Y?
Just did that last night… multiple times…

That’s insane….. it’s like the car dies at 70…

That’s insane….. it’s like the car dies at 70…

My internal monologue:

“well that sucks, I want it to be faster!”

“yeah but when do you even go over 70?”

“Almost never, but I want it to be ABLE to be faster”

“What, do you have such a fragile ego that you’re afraid people will make fun of your car?”

“Maybe? But bragging rights and performance will also help with reviews and resale value.”

“Oh just buy the damn thing already”

“Good thing I have 2 more months before it shows up.”

So these cars are as fast as a tuned Audi A6? I don't plan to drag or race mine but I would like something at least close to the MYP. Can't wait for Ford to take action.

I think the problem starts even earlier than 60+ mph.

Tape shows Standard GT 1.865 on 60’ - I think that’s the best time we’ve seen yet, and very strong by any standard.

But 5.137 at 330, which is not as quick as that 60’ would suggest.

So the vehicle has major potential, but the rate of acceleration seems to be subtly dropping even by 330 feet.

Then obviously a very pronounced drop off by 70.

The initial launch is so strong… I really hope the declining stretch past 60’ can be addressed with an update.
