Mercedes-Benz Announces Subscription-Based ‘Acceleration On-Demand’

[Pushrods&Capacitors]

What??? Really? I have read this forum everyday for the past 2 years. I have never seen that. The GT is supposed to go 0 to 60 in 3.5s compared to 4.8s for our 4X. I have seen several posts where people sold their 4X to get a GT and the extra power. What should I search for?

The GTs are much quicker from a dig, for sure. But, by 100 mph the 4X has caught up, and soon after that it passes it up until the limiter at 113-114mph. My best 0-100mph in our 4X is a 12.3 iirc. GTs routinely take 12.3-12.6 to get to 100. It’s a screwed up situation.

Not sure exactly what to search but there are a bunch of threads in the GT section that get into it. ?

False, but we’ve gone circles around this arguments many times.

While the trap speed thing is true. You’ve never seem to come to terms with the fact that races are won based on who gets to the finish line first, not who has the higher trap speed.

And due to the significantly non-linear acceleration of the GT, it’s bus lengths ahead by the time they hit 100 mph, and zero chance the 4X would make up that distance before it hits 113 max speed only a few seconds later.

The only side by side video of a GT vs a 4x shows how far behind the 4X is in a 1/4 mile. It’s waaaaaay back.

The only race a 4X has a chance vs a GT would be a 75 to 113 mph roll race. And most likely it’d still lose, but not by much.

You and I have both drag raced plenty, so we know what a side by side race looks like. I’m talking about the clock only here, racing the clock or dragy. Not lining up on the street, I wasn’t clear on that. The 4X is as fast or faster to 100 mph (12.3 secs) and beyond up until the 113ish limiter.

And, as you know, depending on the conditions, the 4X may/will also be quicker in passing situations lower than 75mph if the GT is experiencing grey jail bars in significant quantity, think cold ambient temps (30-40F). The GT needs the planets to align for the optimal times, the 4X just runs virtually the same all the time, at least down to 30F range based on my dragy runs. And that’s the problem, as we know.

That’s true (about racing the clock to a speed).

But your post before made it sound like the 4x would “win the race to 100 mph” which isn’t how races work.

Sure, both the 4X and GT can hit 100 mph in about the same “time.” But the GT will do in in significantly less “distance,” which is how races work.

But either way, the fact that it’s even debatable is ridiculous. Not you that’s ridiculous, Ford that made it ridiculous.

The one part of your post that will for sure confuse people is this line “ and soon after that it passes it up until the limiter at 113-114mph.”

From a dig, the 4X will never “pass” the GT. It is possible that 15 seconds in the race the 4X has a slightly higher speed, but it would still be car lengths behind and hit its top speed before having a chance to pass.

Yes, it is still ridiculous almost 2 yrs later.

Also, the 4X runs a 15.x to 110 mph, whereas the best I’ve seen for a tested GT is 17.x, Car and Driver called that one out. https://www.caranddriver.com/news/a38331536/2021-ford-mustang-mach-e-gt-performance-tested/

So, the 4X has a roughly 3 second 100-110mph whereas the GT is 5 seconds for same. It is sad, but likely, that a 4X can feasibly physically pass a GT in a side by side dig race to 110mph solely because the GT is so quick out to 70mph and then just crawls after 75mph. The 4X is very linear up to about 108mph and the drop off to 113mph isn’t off a cliff like the GT after 75mph.

Basically that .8-.9 sec gap the GT puts on the 4X at the 1/4 timing lights gets eaten up by the 2+ second gap the 4X puts on it between 100-110mph. Back and forth with the GT going ahead again after 113mph. So dumb it’s funny, and sad.

Personally not against the subscription options, if I want it I pay if I dont, I don’t. People forget about OTA TV vs cable/satellite, pay for streaming vs pay more for no commercials, every app out there, pay a little more boom no adds but the basics between the free and subscription is the same, 5 gb free cloud storage vs paying for 50 gb, 4$/month for cheaper kw rates at DCFC. People are paying for things that they have forgotten about they’ve been doing it so long. My question is when manufacturers for the sake of streamlining build put seat heaters and other hardware items in a vehicle that people can subscribe to turn on what happens if you don’t use them and something goes wrong with it, shorts out, damaged in accident etc. now I have a part I don’t use but need to fix because mb, bmw, ford, Volvo etc added because it was cheaper for them at the time of build. What about a subscription to use the 10% of the battery kept in reserve for those 1-4/ year road-trips?

To be fair, that isn’t the “best” time posted for a GT to 110.

It’s the “only” published time.

We don’t need to magazine race. We have seen side by side dig races between the GT and 4X and it’s isn’t close.

I posted screen shots of a GT in ideal conditions (best) going from 70 to 124 mph. And the best time for the GT is significantly faster than any 4X.

The problem really comes in “anything but ideal” scenarios.

The GT could get beat when it gets cold or battery too hot or lots of things because Ford is waaaaaaay too aggressive with the grey bars of death.

But to be clear about your “racing math…..” that is just NOT how it works.

A “gap” is measured in distance, not time. If you really wanted to do the math you could calculated the difference between the distance travelled at 102 mph for 1 second (the gap at the 1/4 mile).

Then you could calculate the time it takes for the 4x to go from 102 to 113 mph.

And assume that the GT is going a few mph less.

And the result? I don’t need to do the math, the 4X wouldn’t have enough time to catch up and pass.

Just think about it. If you’re only going 2 mph faster than a car next to you on the highway, it takes quite some time to make up multiple car lengths and pass.

Yes, I know. Plenty of drag racing and roll racing to understand. If both cars launch at the same time it’s likely the GT does stay ahead physically even though it’s 2 secs slower to 110mph. Luckily, we don’t have to rely on online mph to ft/sec converters anymore, Dragy tells us distance covered to mph. I remember some GT owner posted 0-100mph runs where they used more distance than the best 0-100 run I’ve recorded in our 4X so far. Again, the great holeshot was negated by the GT’s absolutely abysmal post-75mph acceleration. Oh yeah, the run below in 90F weather was with AC on auto/65/fan level 3.
