Stopping to cool the brakes, to me, is going back to the 1960s and 70s vehicles. If what you say is correct, and it sounds like it is, they may end up banning the Maverick from these roads.
Overheated brakes is too much kinetic energy being turned Into heat in too short of a period of time because of the brakes’ limits of heat dissipation. If you are going down a mountain pass on a freeway, you are scrubbing energy very quickly. But if you are creeping along at 20 mph, it is taking you 2-3 times as long to dissipate the same amount of heat energy, which makes overheating the brakes at those speeds very unlikely.

The management that runs Mt Washington Auto Road requires your vehicle to have the ability to lock the transmission in 1st gear. That way you don't have to go into the discussion about kinetic energy heat dissipation of brakes at low speeds. Heat remains in the driveline. If you ever drove the road you would understand.

I have driven Mt Washington autoroad. And now I will reiterate what I just said; the 2022-2024 maverick would not have to pull over to let it’s brakes cool down, when descending the autoroad, because it’s brake cooling capacity is adequate for the low speeds travelled on the autoroad.

Also, the heat from braking does not stay in the driveline, it is rapidly dissipated into the environment. Aim any thermal imager at an ice vehicle in motion and you’ll know what I’m talking about.

You realize people might actually believe you and attempt to take their family in a Maverick fully loaded, 5 people with luggage down the autoroad with a trans that upshifts. From what I experienced, it would be dangerous.
You seem to insist it is ok, please provide engineering technical data that you base your decision on. Not that we would understand it, but it would show you either know what you are talking about or you just like to give out bad advice.

There obviously is no data for the task that you are requesting, because it is not a task that requires testing. But the answer can be found with basic algebra.

The maximum combined gross vehicle weight rating of a Maverick with rhe 4K tow package is 8,085 lbs. The elevation loss on Mt Washington is 4,700 ft. That is 51.2 million joules of potential energy. Over the course of the 30 minute trip down that mountain, that means 1.7 million joules of heat dissipated per minute.

Then you take a 3,800 lb maverick with fuel, oil, coolant and a skinny test driver, that is going to be at least 4,000 lbs, out to the ford proving grounds and see if it can dissipate 1.7 million joules per minute without overheating the brakes.

What does that take to make 1.7 million joules of energy per minute? 2.2 stops from 65 mph.

And yes, engineers in the modern age do those calculations for every vehicle they design. That is why you have never heard of incidents of brakes on cars failing from overheating on the road since the 1970’s.

Yes, you can still get cars with failing brakes on the track, but not on the road. And that is what the engineers are calculating for.

Simply put, engineers are good at math and they calculate out the worst case scenarios, based on past incidents, so that their employer doesn’t get sued out of existence.

In our modern era of vehicle telemetry that measures speed changes, the engineers know exactly how much energy the brakes can dissipate per unit of time, before brake fade occurs.

The bottom line issue is that you don’t trust the engineers calculations. So let me ask you, do you have a degree in engineering? Or have you taken the college level math and physics required to understand the question at hand? There’s almost always a huge difference between Joe Average’s gut feeling and what the physics actually shows.

As expected, your data is flawed. Hybrid Mavericks did not have a 4k tow package (until 2025),
Over the course of the 30 minute trip down that mountain, that means 1.7 million joules of heat dissipated per minute.
How can you limit the decent trip time to 30 min? When the brakes fad, speed will go up, not everyone is a trained individual that "knows" how to descend the Mountain, (the basics are to lock trans in LOW, but we know that can't be done). If you read about events in their museum,
a worker went from the summit to the base in 2 1/2 minutes, at points traveling as fast as 60-100 mph.
Recalculate your equation using a 20 min decent time vs the 30 min you supposedly calculated and show how the joules of heat will increase exponentially.
The Mt Washington Autoroad is a unique application that was in no way approved by the Ford engineers in a " worst case scenarios" . You admit that brakes on new vehicles can fail when you wrote " Yes, you can still get cars with failing brakes on the track, but not on the road", I am just trying to make you understand that the Mt Washington Autoroad is not in anyway comparable to conditions found on public roads/highways and that it is more like your term of a "track", again where you admit to brake failure occurrences (and those failures occurred with testing on vehicles that started with 100% brake system condition, what happens if the subject vehicle has worn brake parts - pads, stuck caliper etc etc??) . That is why all vehicles are mandated to be locked in low gear, again something the Maverick can't do.

There are real families involved that could be put a risk by adhering to your theory. Why don't you call the owners of the Autoroad and have them explain why they have rules on what vehicles can and cannot be allowed on the road? Maybe, just maybe you will understand, or it will fall into the category of "You are right the world is wrong".

You are not in touch with reality. I used the ecoboost with 4K tow package as an example of the worst case scenario, since it has a higher combined vehicle weight rating. A hybrid, with the lower weight rating, would have even less problem keeping its brakes in the safe operating temperature range.

And no one has ever descended the autoroad in 2.5 minutes. A formula 1 car would probably take over 4 minutes. The record race time up the hill is 5.5 minutes, repeatedly hitting speeds well over 100 mph. The limiting factor is cornering ability, not horsepower.

Stock vehicles have been safely ascending and descending Mt Washington for over 100 years. Sure, in the 1940’s, you did have to pull over to let the brakes cool down. They were using drum brakes and no power assist. But once the 1970’s got here and everyone switched to disc brakes, the heat dissipation became a non-issue.

Not sure what your deal is with trying to sow fear, uncertainty and doubt about the maverick’s brakes, but it is entirely unfounded.

I’m betting you believe in conspiracy theories. This type of baseless fear mongering is exactly how conspiracy theories get started.

Just like your vice president asked; You think you just fell off the coconut tree?

Now you admit using vehicles not relevant to the scientific Maverick hybrid discussion, as a truck with a greater GCWR (4k tow package) will have different-stronger brake components so it can achieve double the towing capacity. Those components will be an advantage for a truck with NO trailer descending the mountain (you have it backward thinking lighter brakes will be cooler in this extreme situation. Since you can't comprehend the ramifications of light duty vs heavy duty brakes, this will be my last response to you.) .

And no one has ever descended the autoroad in 2.5 minutes. A formula 1 car would probably take over 4 minutes. The record race time up the hill is 5.5 minutes, repeatedly hitting speeds well over 100 mph. The limiting factor is cornering ability, not horsepower.
When you use "probably" in your argument it shows you are probably wrong . Why quote an uphill race time of 5.5 minutes when we are discussing the down hill need for a transmission locked in 1st gear? You started your calculations with using a 30 min down hill time (why use 30 min? If a vehicle made it up in 5.5 min?)(you use scientific terms like "1.7 million joules per minute" why did you chose a 30 min decent time? Why not 29 min or 31 min?) Now you want to include horsepower and cornering ability for the limiting factors but NO MENTION OF BRAKING ability, which to me is the main concern since the transmission, as previously stated, will not hold in the low gear (ratio) leaving only the brakes to keep the vehicle at a safe speed determined by the specific portion of the Autoroad, switchbacks vs straight.

Just call the Autoroad, here is the phone no. (603) 466-3988, and ask if hybrid Maverick with no low gear lock can be used. Then let us know what they tell you and we can put this argument to bed. If your scared to call, ask your dad to do it for you.

As I said in a previous post, you are completely out of touch with reality. The ecoboost doesn’t have bigger / heavier duty brakes than the hybrid. The 4K tow package doesn’t get an upgrade in braking over the base 2k towing capacity. They use the exact same discs and calipers for the Bronco sport (all trims), Ford Escape (all trims), Ford escape hybrid (all trims), Ford Maverick (all trims) and Ford Maverick hybrid (all trims).

Why would I quote a 5.5 minute uphill time? Because you said someone’s brakes failed going down the hill and it took them 2.5 minutes to get to the bottom If a race car can’t do it, there is no way that Joe Schmoe’s jalopy with failing brakes is going to do it in 2.5 minutes I was just making a point that most everything you say is made up BS.

Why did I not mention the braking ability of a race car going up the hill in 5.5 minutes? Because it is irrelevant to the discussion, when the limiting factor on the race course is corneing

Why did I choose a 30 minutes descent time to calculate dissipated energy instead of 29 minutes or 31 minutes? Because the owners of autoroad tell you in their brochure that it will take 30 minutes.

Why call the autoroad to see if the Ford Maverick hybrid is allowed on the road? Ok, I did. The guys says, “it’s not on our list of restricted vehicles”. So I say, “but I was told it might not be allowed because it has a CVT?” Then he says, “I’m not sure, let me go ask my boss”. Then he comes back a minute later and says, “No problem, you’re good to go”.

And yeah, hopefully this does put this argument to bed. Your fear mongering about the Maverick having substandard brakes is completely unfounded.

I towed a 2,000 lb trailer up and back down off of Mt Shasta in my maverick, with zero problems, zero brake fade. It is a 4,700 ft elevation climb, the same as Mt Washington. It is not as steep, but you’re also going a lot faster. I was doing 35-40 mph coming down the hill and it took about 30 minutes. In the end, it is putting the same amount of heat into the brakes as doing a steeper hill at slower speeds, but also taking 30 minutes to dissipate the same amount of energy. Absolutely no reason to pull over to let the mavericks brakes cool down.
