EcoBoost to GT observation

[RagmopInKona]

My EBHHP in normal mode at the roads around here, other than highways, that I am doing 45-50mph the car seems to lug 10th gear even 9th with the rpm in those gears at those speeds if any type of incline with almost no throttle input. (too many police cruisers on the roads to get on it much) Seems much better in sport where at those speeds it is in 6th or 7th gear. I'm averaging 302 miles per tank Assuming the computer is any thing close to correct. Haven't kept records to do the math to double check, as I really didn't buy it for mpg reasons.

My 2020GT Premium before it got totaled and now my 2022GTCS both get/got north of 20mpg combined driving mileage ALWAYS and I am a certified/bonafide leadfoot that simply can't keep my foot off the throttle until I hit about 8-10mph above the speed limit.

In the last 1200 miles my GTCS has averaged 21.2mpg on a steady diet of Costco 93 gas and that's a combination of city and highway miles. The couple of times I reset my odometer to check mileage on the interstate at 83mph I got right around 27mpg for at least a couple hundred miles.

I don't understand how a stock GT could get much worse mpg on 93 octane unless it has some kind of crazy tune or is run in sport mode or something other than the standard everyday mode (can't remember the name of it now).

I'd look carefully at what could be wrong because if you rode with me for a couple of days you'd laugh at my crazy scrambling around like I'm late for work all the time and every stop light is a chance to show off my hole shot. I also pass everything in sight all the time with my foot to the floor or nearly so.

100% stock except lighter SVE wheels and 285 square tires. Never filled with anything but Costco 93, and never broken 17mpg even on the factory tires. If anyone is getting over 18 mpg you bought the wrong car, and definitely don't drive as aggressively as you think. Honestly I think this is true for a good deal of GT drivers. My girlfriend that drives her 4cyl accord nearly a 100 miles a day says that there are only 2 cars guaranteed to drive slow AF; Mustang GT's with older drivers, and anyone in a Ford Escape.

My MPG after driving from St. Louis, MO to Cedar Rapids, IA (~230 miles) at 5 MPH over the speed limit. I filled my unmodified 2018 Ecoboost coupe with 91 octane in St. Louis. Hand calculation shows the computer calculation of MPG averages about 1.0 MPG high. Depending upon wind speed, direction, temp and humidity I get up to 2 MPG higher or lower than this measurement.

Well... I see you either called me a liar or an idiot... I just don't know how it's possible to drive more aggressively than I do and not get lots of tickets. I now have 30k miles combined on my two GT's and once again I've never gotten worse than 20mpg. I rest my case and you can choose to believe me or not. It simply doesn't matter to me.

 

[LDHunter]

As you can clearly see in the last almost 2000 miles I've averaged over 21mpg and I haven't been beaten at a stoplight in months except by a Hellcat Challenger and a late model Corvette. I probably pass an average of 5 cars each way back and forth to work and blast up interstate entrance ramps like I'm in a drag race. I drive about half and half city and highway miles.

Wifey went from a 2019 EB Premium PP1 to a 2023 GT Premium NPP w/ 3.55 gears.

In the EB, she would keep traction control disabled and would occasionally use Sport mode to zip around. The car was twitchy as hell with very aggressive shift characteristics. The rear end always sliding around while turning and occasional straight line acceleration. Sometimes she'd have my head pinging off the window just making a quick run in town for some food/gas/etc. Then we tuned it...using an SCT canned tune. Very fun car to flick around all over the place. I would also keep traction control disabled and unless slow/city traffic, I would live in Sport mode. I eventually got to where I would use Track mode when we were out playing. The P Zero Neros last 40k mi. easy. We had a few previous gen GT kills, even blown, and she caught several newer ones off guard as well, a time or two. My biggest complaint aside from the exhaust note, was having it pull power from me due to not disabling Advance Track. The one time I did was right after a rain in a wide-open parking lot, and before I even knew it I had spun out and was facing the other direction. No more of that.

Now she's in this GT and it's a totally different vehicle aside from exterior cosmetics. Granted we are still on "break-in", so taking it relatively easy, but still getting with it pretty good. We both cruise around, even in town or slow/city traffic in Track mode full time. The rear end is planted, and I don't think we've really even spun the tires. Having the LS diff. vs. Torsen, it definitely doesn't slide around anymore. In some cases this is probably a good thing, although not nearly as fun. The sound is, of course, incredible with the Active Exhaust. We'll be going with a Steeda, Lethal Perf., or Borla x-pipe soon. I expected the change in differentials and the coil-overs, as well as a little weight, but I still didn't expect them to feel as different as they do. I did stand on the gas last night from a 35 mph roll and I think I heard a tire chirp and was pleased with the near immediate power delivery and being pushed back in the seat. It's just a different car, and now I don't think she's insane for wanting to keep both the EB and the GT.

While I would have never bought an EcoBoost for myself, having spent some time behind the wheel of both, I definitely have a better appreciation for the little 4-banger now. I think insisting that it be a Performance Pack greatly contributed to that. Now to get comfy enough with this GT to see what she can do in comparison. I'm thinking it is just a heavier, more planted, softer ride, with more predictible, immediate power, and will lay a lot less Pirelli in the corners. I might look into the 3-piece strut bracing in the Spring.

Post like this idiotic, its like comparing apples to oranges.

At wot from a stop, there is simply no way eb can take on v8. Period. If you talked yeah my eb shit is tuned, then similar comparison will be a tuned gt.

Grow a pair and grow up!

Apologies if it came out like that, and honestly not directed at you specifically.

My only comment on the posted MPG picture is that unless calibrated based on actual driving the computer is optimistic. Mine always reports at least 19 or very close to it. When I check manually that's when I get the actual ~16 mpg. I also don't trust the instantaneous readings as it never seems to correspond with the reality when I hit the pumps.

 

[Bob Lob Law]

I've had my '22 GT for 10,000 miles now. The lie-o-meter says that I average 17.8 mpg over those 10k miles. Figuring it up manually I get 16.3 mpg. Either way, it's WAY better than that of my '22 F250 with the 7.3l and 3.55 gears which averaged 11.2 according to the lie-o-meter(over 32k miles). Actual was 10.6 mpg average. My GT A10/3.55 knocked down 29 mpg according to the lie-o-meter and 27.2 mpg manually calculated on a recent trip.

 

[JBennett]

LOL, someone's triggerd.

On wet asphault w/o Adv Track, yup, she spun right out. Only had that happen one other time, in similar conditions in an F-150 first time out on fresh LS w/ CF clutches and heavy S-spring.

Not street racing, just daily driving and the occasional stop light encounter, or someone egging it on the freeway.

Not replacing the $1,900 A.E we just purchased, just the resonator with an x-pipe.

Not the first mod, no, but will of course look into the strut tower bracing since I expected it to come with it and it didn't. It can't hurt other than cost and a little more weight, right? There are 3-pieces to the puzzle, not just the strut tower brace.

Apparently you feel like there are other handling mods that need to be addressed before trying out strut bracing? We haven't driven it enough to know where its perceived shortcomings are yet to go throwing big money at.

I’ve had 3 S550s at this point and easily the best thing I finally did was a wheel and tire upgrade. Found some cheap GT350 wheels and went 305/35 rear and 295/35 front. Such a huge difference in handle. I’d argue the stock 255/40 were borderline dangerous.

If you decide to install the cowl extension, cowl brace, strut tower brace, and lower K brace, all the relevant part numbers and a good installation guide are in the below thread.

https://www.mustang6g.com/forums/th...extension-lower-k-brace-install-guide.100800/

I agree with the others that these parts are not weakest link in the chassis and suspension of a non-PP GT. I'd start with IRS bushing lockouts, IRS braces, and differential bushing inserts from one of several suppliers: BMR, Steeda, UPR, etc. Next step would be shocks, struts, and springs that are tailored to your driving style and interest.

My Mustang GT convertible averaged 21 mpg for the 4 years I owned it. I am not a super aggressive driver, but I do have some fun with the car. Most of my driving is suburban boulevards, so that does limit me. Odds of hitting an SUV or 4 door pickup truck are extremely high if you hit the gas too hard. They make up 75 - 90% percent of the vehicles I see on the road and they seriously obstruct your vision, as well. I did get 30 mpg on a couple 2 - 3 hour drives on the highway at 70 - 75 mph, but I was really trying for gas mileage.

Not fer nothin' but.
There are a lot of meatsuits in the drivers seat of these cars with almost no driving skills, and no matter the car, tire smoke doesn't = fast.
Just say'n.
And if you find yourself in need of use'n the traction control in any stop light to stop light fun and games, you just might be one of the meatsuits.

 

[Unas2k5]

Let's recap;

Both you and your wife drive the EB so hard, you're just sliding all over the place like the Dukes of Hazard. And the AdvanceTrac caused you to spin in a parking lot.....not your driving. But despite all the sliding, you're convinced the tires will last 40K miles.....easy.

But you then tuned the car with an SCT canned tune, and that made it a "Very fun car to flick around all over the place." So even more sliding, but it gave you the courage to actually engage Track mode.

You and your wife also regularly take the EB street racing, and have gotten "kills" against previous gen GTs. Quite often. Including more recent (and "blown") model year GTs that you "caught off guard". So not just sliding all over the road, but fantasy street racing.

Brilliant.

Now you bought a GT. You LOVE the AE, but your first thought is to remove and replace the resonator. And your first mod that you've determined the car needs, is a "3-piece strut bracing".....whatever that is.

Nothing to do with the IRS/cradle. Or shocks/struts. Or tires/wheels/brakes. No.....it's a "3-piece strut bracing" your GT needs.

Please....shoot me in the face with a bazooka.

Just gonna quote all this before the back-pedaling starts.

as a PP1 GT 6spd owner I'm gonna say the EB cars are easier to drive fast for 2 reasons:

1. they have less power overall
2. they have more power down low

so the GT needs to be launched hard (but not too hard) and then you're fine from there but the EB just has tons of midrange power but runs out of steam at the top. SO if a GT dude doesn't get the jump i could totally see a EB taking him for a bit.

of course everybody knows all this and just says "well its a shitty GT driver" but what that really means is... its easier to be fast in a EB car. sorry guys, its true.

the key with the PP1 GT is you just gotta go harder than you think you should need to and it'll reward you for it. there is no pussyfooting through the tulips with the coyote.

 

[Jackal]

That's exactly what I THINK I'm dealing with...not as much immediate torque off idle and a more lax rear diff. Going to some "testing" this weekend. ;)

I assumed it would be settled sCiEncE around here long ago, but I guess not? I wouldn't go betting the house over it or anything, but the EB PP1 didn't seem to have much trouble jumping out front of GTs for a decent portion in the first 1/8th? The first race in StangMode's YT vid where he snuck his EB into a 5.0 event this very thing happened, although I'm not sure on mods. The EB was a convertible though!
