What has been said is true. In city driving I rthink the v8 is as good as the v6. On a long trip the v6 may shine. But when the smaller motor has to keep moving the car from a stop, it falls short.

I've decided this current tank I'm on will be used to see how high I can get the MPGs on my work commute, so that means no faster than 70mph on the highway and limited flooring it. So far it looks like I'm getting about 25 MPG with my 3.7L according to the computer, but in my last 3 fillups it seems that the average that the car gives you is about 2 MPG lower than what you get from actually calculating miles driven / gallons used. We'll see how well it fares once this tank is used up. I'm also logging each fillup and will post a years worth of MPG data around this time next year if you can wait that long for some solid figures

Mileage

We also have the issue here of people reporting mileage by what is stated on the dash. This value is less than actual MPG when hand calculated( several threads on this). It takes just a minute or two to figure actual mileage when you fill up.

 

[OAC_Sparky]

My engine's not broken in yet (2600km/1625mi) and I'm averaging between 21 mpg (11L/100km) with some spirited driving to 25mpg (9.5L/100km) on the highway cruising in 6th at 74MPH (119km/h).

Of course, I'm not driving it with my foot nailed to the floorboards but I'm not exactly babying it either.

[HossWhisperer65]

Just for laughs, last night I put my GT (3.55:1 diff) into 6th and set the cruise control to 43 mph for a few miles - 31.2 mpg per the digital readout! Cowman, I agree: the readout is conservative by at least 1 mpg per tankful.

 

[Kona Blue Pony]

I'm in the exact same boat.

I'm at like 19.5 MPG (DIC Calc.) right now with a 1/4 tank left. I'm doing mostly city driving though. I'll be driving from Northwest Indiana to the Wisc. Dells on the 15th and I can't wait to see what kind of mileage I can get. The car is 20 miles shy of 1000.

It will increase a little more. I think it took a couple thousand miles before our V6 "leveled out." It increased a little each tank. My wife drives the car 40 miles round trip to work and back, a good 60/40 city highway with the city being stop and go 45mph and the highway being a clean open 65-70mph. She's averaging around 24.5-25mpg per tank with the dash readout @ 23.3mpg. The only problem is that I get behind the wheel on the weekends and it drops down a good bit :hihi: I'm VERY pleased with the fuel economy of this car. Before it was even fully broken in it was taken on a 350 mile round trip and was just shy of 30mpg.

In SC you also have to pay yearly taxes on vehicles. I believe the GT's are taxed a good bit more than the V6's. My Z71 is ridiculous because it's a 4x4. It was 5 years old when I bought it and it was still almost $500/yr. It's finally down to ~$150/yr but my 2wd S10 which is only a year older is only ~$50/yr. Insurance, fuel mileage, initial cost, taxes, and my wife doesn't need a V8 are why we got the V6. We paid cash for it, I hate payments.

 

[mad4macs]

I'm on my 4th '05 + 'Stang and my '11 V6's mileage blows the 3 older eight's into the dirt.

Mind you, I only drive 35-40 thousand miles per year, but it's enough to see an appreciable $$$ put back into my pocket.

I got the tax bill on my 2011 Mustang back in February and let's just say I'm pretty sure there was a period where I passed out because when I snapped out of my stupor, I wasn't in the same place I was when I opened that letter. I'm dreading the bill for my Sonata that's bound to come before the end of August.

 

[Mountain]

For me:

Medium to Low Stop-and-Go = 19-22 MPG

Heavy Stop-and-Go = 18-19 MPG

Cruise (anywhere from 60 MPH to 80 MPH) = 30 MPG+ (can get 34/35 at a little above 60 MPH and around 2,000 RPM.)

Mixed (City/Highway) = 25-28 MPG

We have the same car, 11 V6 prem. w/ PP and for Greenville County I'm pretty sure our tax bill was $410? We had a brand new crew cab prerunner tacoma in 2005 and it was well over $700 the first year. I almost poo pooed my pants. I'd bet a GT is at least 550-600/year???

 

[adampiecubed3]

My comute is pure city driving and I have been seeing my mpg in the high 17 range. It's pretty warm and humid where I am too. Only mod is a sct tune and I don't race it to much. The only time I see above 20 is when I'm on the highway for long periods of time.

 

[PGT96drvr]

Well, I am averaging about 17 with mixed city/highway driving. So what that tells me is that I'm probably doing 13-14 in the city and 22+ on the highway.

I have no idea how people are managing to get 20+ in mixed driving, unless it's a lot of highway.

Same here. I don't have the heaviest foot by far and I get 14.5 City right now. Stats in Sig.

I have a 2011 GT Premium automatic (late September 2010 build) which is the first car that I have owned, having owned and driven F-150 trucks ranging from model years 1979 through 2004. My GT now has roughly 7,800 miles on the odometer and has had its gas tank topped off 27 times with premium 92 or 93 octane. The overall gas mileage to date is 25.49 miles per U. S. gallon (calculated by hand, the displayed MPG is typically 6% to 8% lower). The highest achieved mileage over a tank of gas was 28.76 MPG with 1100 miles on the odometer (one day between fill-ups). The lowest achieved mileage over a tank of gas was 22.88 MPG with 6200 miles on the odometer (14 days between fill-ups). The highest partial tank MPG that I have seen happened immediately after the fill up with the lowest MPG; fill up, drive 45 miles (parked the car once in the 45 miles), periodically look down at the MPG reading and see that it gradually increased to 29 MPG (if the display is 6% lower than actual, the actual MPG should be 30.74 MPG).
My daily commute to work is roughly 6 miles each way, roughly 25% city and 75% 55 MPH country roads. A short commute like this seems to be too short to achieve decent gas mileage; the displayed mileage recently dropped from a displayed 26 MPG with ¾ of a tank of gas remaining to a displayed 24 MPG after driving to work 5 or 6 times. With ¾ of a tank of gas remaining, starting the engine kills the gas mileage by roughly 0.2 MPG, and it typically takes about 15 miles of driving to recover the lost MPG from the start up.
I understand that there are differences between cars, even those with the same specifications. There are also differences between where you drive and your driving styles. What seems to work for me to achieve decent gas mileage – these might help someone else:
* Drive the speed limit
* Fill the tires to 35 psi
* Keep the RPM below 2,000 when possible, and use the highest gear that does not cause lugging
* Coast when possible – try to avoid moving directly from the accelerator to the brake pedal, leave a bit of a gap between you and the vehicle in front and use that space to allow the car to coast if the vehicle in front slows down
* Don’t abandon spirited accelerations, but it probably is not necessary to exceed 5,000 RPM when leaving every stop sign/stop light
* Always display the car’s calculated MPG as a constant reminder that while it is fun to leave black marks when leaving the Ford dealerships, doing so hurts when it is time to visit the gas station (or the tire store)

I disagree to some extent. The cars vary.

I'm on my second 5.0. Both were identical cars.

The computer in the first one, over 14,000 miles was within a tenth of a mile per gallon versus hand calculations. Usually the readout was higher in that case.

My second car is off by about a half a mpg to a full mpg and the readout from the computer is always low.

Two cars with VIN numbers 5 apart built the same day. They have the exact same options and paint color. Both were/are spoiler delete. Identical cars.

The first car got better mileage by almost a full mpg over the same trip with similar weather and traffic. It's a repeat trip for me that I do at least once a month. I even fill up at the same gas stations.

When it comes to property taxes on cars, Lexington tends to be a little high. When I got my first bill for the Mustang in March it was $710.55 which damn near gave me a stroke. I was expecting high but not that high. After I got it together, I had a talk with Assessor's office to see how they determined that a car 1 year old was worth more used (they assessed it at $29,670 when MSRP of it new was $28,685). Then they send out a 2nd assessment (using Blue Book Value of 2010 Mustang I assume) of $23,830 which made the taxes $571.86. I'm sure I'll have to fight with them next year when they raise the value back up.

I'm almost dreading getting the tax notice on my Sonata next month.

 

[illestdomer2005]

It's more a question of whether the higher insurance and extra $6,000-$10,000+ price tag is worth it. To me, it wasn't. But then I'm on a tight budget. Not as fortunate as a lot of you out there.

If price were no object, I'd have gone the V8 route, specifically the GT500. I would not have had the patience to wait for the BOSS or the GT350.

I was in a similar position. My previous car was a 1990 Honda Accord. Yeah, I had earned a new car. That said, my wife drives a 1998 Ford Contour Sport. So, it seemed a bit foolhardy to me to splurge on the GT when the V6 was plenty fun. You end up paying about $100 less per month based on a 5 year loan and varying amounts on your insurance...as well as less to Uncle Sam.

The salesman let me take home the GT for the night, and I knew that I would have my license shredded. I already got two speeding tickets in 2010 with my friggin Honda! I have a lead foot, and I cannot drive too fast; so, the last thing I need is a 400+ HP beast under my foot...

As far as MPG are concerned, I am getting nowhere near the advertised fuel efficiency, but I have noticed that it goes up considerably when my wife drives it

I've posted this in several places, but here it is again: I completed a 233 mile one-way trip on the freeway this weekend, averaging 100 MPH for nearly all but 30-50 miles of the trip, where I had to slow down to 60 MPH. 2.73's running @ 3000-4000 RPM the entire trip, as I kept rowing the gears between 3rd-6th depending on the traffic. I was in the mood for keeping passign power on tap and didn't care what fuel I'd have to burn. Lo and behold, it panned out to 29 MPG average (manually calculated) on 8 gallons of 91 octane. Again, 100 MPH for a majority of the trip.

^ wow. 3.7 ftw! I need to keep driving mine until it's all the way broken in. Granted I only have 350 miles on her and I'm averaging 19.9 per computer but probably 21-22mpg if I hand calculated it out. It'll be nice if I can average 23-25 per tank. that will hang in there with my old 2007 2.3l ford fusion.

What is this property tax on cars you speak of? Don't you pay a sales tax on the purchase price? Just curious

Maybe he's talking about ad valorem taxes? When I lived in Memphis, tags were higher and based on the county you lived in, but they were the same for a beater as a Bentley. In Georgia, it's all about the car.
