I wonder if the trap speed could have been a little better if they folded the mirrors in - save that aero drag!

Spray some methanol on the battery casing!

Crazy that the Lightning crushes the Mach E GT in 1/4-mile trap speed.

Imagine you've got a Mach E GT Performance at the drag strip, you go up against a Lightning Pro ER Landscaping truck, and starts reeling you in FAST at ~80mph and blows by you at ~100mph as you are crossing the 1/4-mile mark.

Ford needs to fix the Mach E GT, IMO, but it's clear they've improved the cooling for the Lightning or the larger battery allows full power to last longer before thermal throttling.

Another thought: I wonder if there's any effect from the Max Tow Package cooling in this case.

Ford doesn't have access to big brakes for F-150s?
EVs are heavy and get up to high speeds in short distances … seems obvious to up the stoppers.

I'm sure they're fine for towing (no problems in my Hybrid) but it seems to me Ford must have encountered the brake limits and somehow decided it wasn't worth so much as a better rotor and pad?

Tesla has always had terribly inadequate brakes. Rivian has great brakes (and the R1T is a lot quicker than a Tesla Model 3 Performance.) It didn't occur to me that Ford wouldn't upgrade the brakes on the Lightning.

If regen is working properly, you should not need bigger brakes. Regen with 2 motors acting on all 4 wheels should be pretty strong all on its own. I am currently using a Kia Niro EV (regular EV in shop) and when I set the regen to the highest level, taking my foot off the accelerator results in a very significant braking force - with no help from the discs/rotors.

It makes me wonder why we are not seeing this in the F150 so far.

It's a good point about regen, but I guess it depends on how much the braking distance was limited by the tires vs. the brakes. If it's the tires, additional regen won't really help.

Here is a reference for other trucks 70-0 from this site: https://www.carindigo.com/ford/f-150/0to60. The F150 here is a 6.5 ft XL with the 3.3l. The Lightning measures up here at least.

But this site says the 2021 Powerboost 70-0 is 148 ft: https://www.evpulse.com/news/2021-ford-f-150-hybrid-xlt-acceleration-and-braking-performance-tested

I agree that with a lot of "go" you also need a lot of "whoa."
Stick the equivalent weight of the batteries in the powerboost bed and stopping distance no doubt would increase

Not sure, but after Out of Spec Kyle's video, I added it to my order. This just makes me even more happy that I did.

The braking force you get from Regen isn't even close to the force of an emergency stop - which is what they were testing.

When we test (and are going to test it again) emergency braking in our Kia Soul EV we get nearly 1 G worth of braking force. This is because of the combination of regen+brakes. The regen adds significantly to the braking force.

I would expect to see the same in an emergency stop with an F150. Even with low-rolling-resistance tires we still get insane braking in the Soul EV.

Indeed, friction brakes are absolutely ridiculously strong. Bigger (balanced) brakes not only provide better brake force modulation, they are bigger heatsinks that allow for repetitive stops without fading. I think better pads are needed here to reduce brake fade, and better tires are needed to reduce stopping distance.

LRR tires have terrible grip. I thought my Model S was borderline dangerous in emergency stops with the original LRR MIchelins. I could easily activate ABS, but stopping distance was huge. With performance all season tires the car stops like a champ.

OK, when are we getting an aftermarket carbon ceramic brake kit for the lightning? :)

Pro ER will be the fastest...all those fleet drivers are going to be tooling around in sub-4s trucks.
Only the ones that aren't limited down by their companies. You really think companies would allow their employees to drive a truck that fast?

I had a summer job in high school for my city’s parks & trees dept. One of the trucks had a 350 V8 in it…that was more than enough to get in trouble.

17 year old me behind the wheel of a lightning would be baaaaaaaaaaaad news :ROFLMAO:

Truly smart companies will remove the throttling so their employees get to the job site in half the time, and make lots more money! /s

Regen's great (especially in newer cars with much higher regen power) but doesn't come into it when testing performance (whether it's straight line or race circuit laps.)

There's youtube influencers showing "one pedal" driving of the Lightning, if that's what you've not seen.
