Instant vs easing into it

[Mach1E]

I’ve noticed recently with the GTPE that it actually feels faster if you don’t stab the throttle.

This seems true from a stop or a slow roll.

I think I know why:

1. less likely to spin the tires so you feel max acceleration when you hit max torque around 40 mph

2. I think your body can’t quite register what’s happening when you get instant torque so it doesn’t feel as fast

Thoughts?

Side note: I know that doing this results in slower 0-60, 30-70 times etc, I’m just talking about that seat of the pants feel. Similar to how a big turbo car feels with lag then when boost kicks in.

Thoughts? Get your Dragy out. I’ve found that our 4X gets 1.9-2.0 0-30mph when I brake torque it and roll into the throttle quickly, however, it only gets 2.2-2.3 when I brake torque and mash the throttle fast. A 4.9-5.0 60 run becomes 5.4-5.5. That’s something you can feel. Even with TCS off I think there is some power/current limiting occurring when you just slam the throttle open. May be the same for the GTs…

Interesting. So maybe it’s not just in my head? No draggy for me, but hopefully someone could test it.

I’ve asked, but haven’t gotten a clear answer yet on launch technique as to what is faster. Brake tq none, a little, a lot? Just slam the gas or ease into it?

But this is the first I’ve heard anyone suggest easing into the throttle.

I’m getting more data together and will post runs in the near future. As far as throttle application goes, it’s more of a smooth, quick application than just easing into it. It’s a fine line. Kinda like how you might launch a manual when slipping out the clutch a bit so you don’t hit the tires with everything all at once.

It’s all kind of ironic when you think about it because part of the allure of AWD and EV is all of that instant torque and great traction. Yet, here we are figuring out optimal launch technique anyway.

My damn SS cuts 1.9 0-30s ?

I have noticed the same thing with my GT. It definitely feels faster (at full throttle) if you slowly (lets say over 1-1.5 seconds) go to full throttle than if you just slam it.

Hmm, now I’m wondering if there is some sort of tq management built into the programming like they do for automatic transmissions on ICE vehicles.

It also could just be a matter of traction.

I find stomping from a standstill very easily has the front tires struggling for grip on poor road surfaces or when on inclines, where as if you are already crawling along and then give it the beans there tends not to be an issue, then again it is pretty easy to have the traction control cut in just accelerating out of a corner so traction issues are not limited to accelerating from a standstill.

It is probably easy to test by capturing a 10 to 60mph time and see if there is any difference between doing it from a standstill or from moving and compare the times to rule out if it just perceptually feeling quicker.

From a performance perspective the GTPE with the magneride coupled with fine amount of control you get with electric motors should allow the for the right amount of tire slip to get the best possible launch for the conditions.

As not everybody wants to launch away from every red light or stop sign, it should really be a case of left foot on the brake stomp the gas wait for a launch control active to appear on the dash then foot off the brake and away it goes, yet while you can find launch control on various performance Ford vehicles including hot hatches costing a 1/3rd of the price the fact the GTPE does not have one sums it up for me. At least a launch control should be possible to add so maybe Ford will get around to adding it via OTA
