2011 Mustang V6 300hp / 31 mpg hwy
EPA 19C / 31H
I bet one of us could get whole tanks of 32 or better in a six-speed while still enjoying some spirited driving. After seeing the commercial last night, I've been having dark thoughts. May get my Mustang out on Friday. I want.....

2011 Ford Mustang V6 rated 31 mpg highway, most efficient 300+ HP car ever — Autoblog

Youtube video:

Ford is doing some great things with their cars, even the Mustang. I'm excited to see how high the V8 version rates. So smart to beat the camaro on power and MPG, and flash the numbers, especially 31 mpg, eight times during the commercial while you hear its motor revving and see it driving...
My '95 GT got 23-ish on my most conservative tanks.

Be strong :)

They are driving around the city saying 31 mpg (without properly qualifying it), that is pretty dishonest, not "smart". Under those conditions it should be saying 19mpg. And if you do a lot of those powerslides it should be flashing 5mpg in huge red letters! :)

autoteach 05-05-2010 10:51 PM

The camaro is at 29 mpg hwy, and it has 304 horsepower. I wouldn't say that they beat the camaro, but both have beaten the v8. The great thing is the camaro 6 handles considerably better than the 8, so it begs to wonder why would anyone buy the v8?

mcrews 05-05-2010 11:03 PM

the Ford Taurus SHO has the (I love this....) EcoBoost V6 making 365hp.

oh yeah.....EcoBoost is a twin-trubo!!!!!! on the v6!!!!! my 02Q45 only makes 340hp in a small 4.5l V8

darcane 05-06-2010 04:13 PM

I was getting 29mpg hwy in a 300hp car. (w/o hypermiling techniques)

It was built by Chevrolet...

17 years ago...

(Specifically a 1994 Corvette)

mcrews 05-06-2010 04:32 PM

When I got married in 1986, a good friend of mine had just bought the new corvette.
He drove from Dallas to San Antonio with his wife to come to my wedding.
He's telling me how he got 26mpg driving like a madman down hwy 35.
he had me come uot and look at the car and the display........I was impressed!!

He and I had been racing 1979 Mazda RX7s in Showroom Stock SCCA SoloII.
Needless to say, that Vet V8 was a stepup from the Rotary motor!! The Rotary had a 4bbl carb that opened pretty quick (I wear a size 13......) I think the best mileage I ever got was 18mpg!!!!!!

The Vet is a classic example of the use of lightweight material, overdrive gears and aerodynamics.

They have been doing this for years. Started in the 70s.
The truth today with giant plenums and a hopeless balance of 6 cylinders at a wrong angle untl boxer'd.. man o man. They must think we are all stupid.

convert it to realtime draft and see how fast it dies with real'll do 31 alright, for 60k miles tops...and a carburator you can take with you when it dies..

One of the road tests I found showed the infamous rear axle hops the v6 always dishes out...amazing marketing, I am glad you tube exists and regular people with thier cameras.

"shoulda had a v8" is a saying I recall...the difference is so minimal, in consumption, the balance alone is worth the v8.

gascort 05-08-2010 12:26 AM

well, they do cite it as 19 city, and I bet it's more like 0.5 mpg when doing real aggressive driving.
I would love any of the cars with the ecoboost turbo engines. I really hope they appear in the 2012 focus. My wife wants a new car and she's looking at VW TDIs and we may have two cars to shop if Ford offers a fun to drive and fuel - misering turbo car.

Oh, and I washed the Mustang off for the first time in a year and drove it for the first time in weeks today. Man it was fun. Glad I have the escort so I can afford to drive the 'stang on occasion and not swear at the gas pump weekly when I fill up. ;)

dyerjg 10-06-2010 05:02 PM

Sounds like mustang hate to me, I have a new 2011 base mustang V-6 with the manual 6 speed and I am above 25 MPG around town average. I don't get heavy footed very much, but do coast down to stops and such. I've just passed 900 miles driven and when it was new I took it on a 65 mph cruise on the highwat and got a tad past 33MPG. Not to shabby, can't wait for vacation next May to put it cross country. I will keep the average for the whole trip and post it up.


EdKiefer 10-06-2010 06:39 PM

Don't just look at HP # , look at TQ and what rpm, that's better judge for performance . The ecoboost have nice TQ # (350 @ 1500-5250 rpm ) .
On Camaro vs Mustang , the mustang is few 100lbs (300lb) lighter AFAIK .

Mustang Dave 10-06-2010 09:54 PM

My 2007 Mustang V-6 with the 5-speed "bolt action" should get between 17 (city) and 25 (highway), according to EPA's 2008 revised estimates. I had to start it in my garage to charge the battery a couple of times during the winter of '07-'08 to get a fill under 25 MPG. Since I found, the only time I get less than 29 MPG on a fill is on road trips. And I haven't gotten through a tank yet without "putting 100% spurs to it" or squealing the tires at least once. ;)
Maybe some aero mods will help my highway MPG.

The flat torque curve that those 3.5L ecoboost engines put out is amazing. I am glad the new F150's will have them, I just hope they are moderately priced.

tjts1 10-07-2010 12:47 AM

There is no ecoboost mustang as far as I know. Not yet at least.

Not yet but it would not surprise me if they bring out ecoboost option for most all models .I think that would be good idea ,depending on cost of course . Read somewhere there also bring 6 speed DC auto's as option on many models too .
For Mustang I could see a small V6 ecoboost work nicely, somewhere in the 3.2-3.4 L size(just destock the 3.5L ) , power/TQ but still some better mpg . As the Mustang is a lot lighter than the ecoboost Taurus .

My 07 Mustang GT is rated 15/23, and right now I'm running ~21-22 mpg on my daily commute. Highway trips easily hit 26+ mpg at 70 mph. The 31 highway mpg of the new v6 means 35+ mpg is within reach easy.

Absolutely! My '07 V6 is rated 17/25, and I've only gotten under 25 ONCE! And since May, 2009 (when I found, I haven't had a fill under 29 MPG (strictly commuting to work; road trips are another story...). I believe I could easily get 35 MPG out of an '11. I'm just not willing to pay for the depreciation on my '07 to prove it.:)
People have a hard enough time believing that Ive squeezed over 31 out of my '07. (without any mods or extreme hypermiling techniques)

Maniak 10-20-2010 11:52 AM

Our 2006 v6 mustang (manual trans) gets a mixed mpg of 25-26 mpg.. with no ecomod driving

Yolanda's commute is 35 miles, and its 50% highway (speed limit is 75), 2 miles dirt road, 8 miles 2 lane (50 mph zone) and the rest is through town. She is averaging 25-26 mpg.

On the freeway she tends to get in the upper 20's. When I get to commute to work with her car (pretty rare) I can get 30mpg average. Same 2 mile dirt, 8 miles 2 lane, but then its only 18 miles of freeway then another 2 miles on the ourskirts of town.

I use a few ecomod driving tips I've picked up here (coasting, constant load etc) and it has helped. I average about 1-2 mpg more than her on the same route.

Oh yea, the motor on our mustang is definitely broken in. Its creeping up on 150k miles.


landrew 12-03-2010 02:37 PM

I can't wait to see what numbers people can get with the help here on the new F-150 ecoboost. Sounds promising....

winkosmosis 11-30-2011 05:54 PM

Does anybody have one of these 3.7L Mustangs yet?

66sprint6 11-30-2011 06:24 PM

Word on the street is the SVO is comin back and...well...DUH, itll be sportin some sort of Ecoboost setup which I am VERY excited about. I miss my old 84 SVO and would consider goin into debt over a new one LOL

I am thinking about buying a 2007 Mustang V6 Manual and I wanted to get an idea of what to expect. So I rented a 2012 V6 Mustang Automatic from Hertz today and went on a road trip to get an idea what kind of mileage I could achieve.

I drove 300 miles. The first 60 miles was all highway traffic. I simply sent the cruise control at 65 mph. At the end of that 60 miles my Ultra-Gauge reported 38 mpg.

The next 30 miles was on State Highways with a 50 mph speed limit. I again set the cruise at 55 mph. MPG was about 36-37.

The next 80 miles was on 2 lane windy roads (Hwy 101 on the Olympic Peninsula). I drove all of this section in 3rd gear instead of drive to get an idea of more spirited driving. I kept it within 10 mph over the speed limit, and never accelerated at full throttle. Spirited, but still smooth throttle. I had 26 mpg for that segment.

The next 100 or so miles was again on State Highways. Traffic was quite a bit heavier, so most of the time I was varying speed between 45 and 55. I think I had 31 or so mpg for that segment.

The final 30 or so miles was in the city of Seattle and it's suburbs. I think I got 27 mpg for that segment.

At the end of the 300 mile trip, the mpg gauge in the Mustang reported 29 mpg overall average. My Ultra-Gauge reported 32 mpg and doing the math after filling the tank back up also came out to 32 mpg (309 miles and 9.6 gallons to fill the tank).

I did not do any hypermiling driving techniques, other than not being very heavy on the throttle and keeping the speed near the speed limit.

I really want to get the 2007 Mustang V6 I've got my eye on, but I don't think I can expect to get as good of mpg as I got with the 2012 Hertz rental. I know it had the newer V6 with dual instead of single exhaust. I think to get the higher EPA rating the new Mustang uses a different rear axle ratio than previous years. I wonder if it's possible to swap that into older models.

Overall, I was quite surprised how easy it was to achieve over 30 mpg. Even when I spent an hour and a half or so driving in a lower gear I was still getting pretty close to 30 mpg. I was really shocked when I got 38 mpg for the first hour of all freeway driving. Makes me wish I'd done that at 60 mph instead of 65 mph. I might have hit 40 mpg.

If I could afford it, I would be buying a 2011-2012 V6 Mustang today. But that's out of my price range so that's why I'm considering a 2007.

mcrews 02-05-2012 01:35 AM

there is a guy on here w/ a mustang.....he gets decent mileage.

Changing out the rear gear is very doable.
also, if you do a far amount of hwy driving, running a taller tire (nurmorus threads on this) will also help

tjts1 02-05-2012 01:58 AM

The 2012 3.7 engine has nothing in common with the 2007 4.0 motor. Very very different animals.

mcrews 02-05-2012 02:01 AM

true, but mustang dave has a 07 V6 and i believe he gets 30+ (when he keeps his foot out of it!!! :eek:) :thumbup:

mcrews 02-05-2012 02:04 AM

and true, the 2012 is a very different breed than the 2007. (kind of the point of ths post) Ford really wanted that EPA MPG number. And designed the car to get it.

tjts1 02-05-2012 02:11 AM

2012 motor has vvt, DI, an extra 100 hp, improved aerodynamics and reduced weight just to name a few.

..and exploding driveshafts:
Why do 2011 Ford Mustang driveshafts keep exploding?


gone-ot 02-08-2012 08:26 PM

...using Microsoft-speak: "...that's not a defect, that's a mechanical fuse to keep you from exceeding the manufacturer's designated 'limit." -- uh-huh, uh-huh.

pete c 02-08-2012 08:34 PM

a 2.5L 4 cylinder ecoboost SVO stang would be pretty sweet. I would think that such a rig with a 6 speed with tall gears should be able to get close to 35 mpg on the highway.

mcrews 02-08-2012 08:52 PM

I had a 1979 Mustang Pacecar with the 2.2 liter w/turbo. It was a sweet ride. Never checked it for mpg.........:o

It was a 5 speed.

At 129 it was smooth as silk but I thought....if something breaks .....i'm toast!

I can't imagine how stupid someone is to take a V6 mustang to 135mph!

darcane 02-10-2012 02:23 PM

Well, I did have the smilie in there as I wasn't entirely serious with my post.

But, I think it's reasonable to expect the driveshaft to hold up at speeds in the 130 mph range. You didn't expect yours to fail at a comparable speed. If it were a three year old V8 Mustang you wouldn't expect it to fail, right?

Keep in mind that the current V6 Mustang makes more power than the standard V8 in 2009...

mcrews 02-10-2012 02:27 PM

No, I agree from a quality issue.......
But I still think it's nuts to run a Mustang to 130+

(of course, I'm over 50........)

I see nothing wrong with it myself.

Of course, I'm planning to go at least that fast in a 25 year old Corolla...

I had a 1980 transam with a 400 pontiac, 350 turbo tranny. cost me $10 an hour to drive just out of college when gas was cheap. not bad. same car eventually went to 425 oldsmobile bigblock, 10.5 compression, 4speed with 30% overdrive on stock whatever 301turbo rearend gears those cars came with. stage 2 centerforce clutch Had some huge tires on the back, so big I had to install 10 inch shackles to get the rear wheel to clear the fenders. the shocks regularly bottomed out. 3 inch flowmaster 40s. In overdrive at 65mph the engine barley turned 1800rpm, barely touched the skinny peda, just purred along in high idlel. I dont remember the mileage i was getting but it was pretty good. spent a few months driving it back and forth to home on the weekends and I dont remember many fillups.

that damn oldsmobile never ran right. Got screwed by the engine builder who put in some bent rods and wrong cam andI spun the bearing 400 miles after getting it. I did the bottom end and got a cam from Mondello, those *******s gave me the wrong cam too. there are 39degree and 45 degree v8 bigblocks, somehow I kept getting the wrong one. eventually I gave the car away. literarily. bought a 10 year old bmw325is and gave the bird to my buddy
