Ecoboost MPG on new cars

[Ponykix]

5236.4 miles. 197.332 gallons. A hand calculated average of 26.536 mpg. The car which hasn't been reset since new is saying 27.7 so just over 1 off.

I've seen as high as 29.48 and as low as 24.48 on an individual tank. Again hand calculated. I'm about 70/30 Hwy/City on average.

I live less than 30 miles from Dirtleg with same spec car seeing roughly the same average mileage and high / low. 6231 miles showing 25.7 with some time at VIR and 70/30 Hwy/City mix as well.

The trip computer says 26 around town and 30-32 hwy depending on where I'm at (30 with VA drivers), but I then top the tank and do the math, and I'm at least 1-2 mpg better than either of my hwy/city ratings on the trip computer. Not sure why its that far off, I am on stock wheels/tires/diff.

Looks like we have twins as well. Who do you run with at VIR?

Trackdaze, Rezoom, TCUSA, and SVT Mustang Club. But I am slow...

Rezoom, PCA, Trackdaze (only once) and Chin (only once). low 2:10's in the old M3. We'll see in July with the new Eco.

1500 miles and I'm at 23mpg on average. my commute is 14 miles one way to work, and its a mix of 70/30 highway and city. Lowest is 21 and highest is 23. I want to get the factory estimates as an average consistently. Dealer filled up 87 when i got the car but I've been filling up 92 since then.

I wind up with a lot of stop-and-go with 55-60 mph speed limits in my usual weekday driving. Pretty stupid traffic situation really, and I wind up getting 23 mpg usually. I think I could get it up to 25 if I tried shifting sooner and behaving myself better, but what's the fun in that?

I did take my first true highway trip across the state and back at 60-odd (3200 miles on the odometer), and got almost 34 mpg one direction, and about 31 mpg the other.

I've averaged about 30.1mpg on a 200 mile road trip doing 82mph. If I slow it down to about 72 it jumps to mid 31s.

Around town my average is about 24mpg.

My wife is driving a 2015 V6 and she gets about 21 to 23 city. She has over 4000 miles on it. I just got my 2015 Ecoboost (PP) last week and already 23 with 250 miles on it.

I'm at 3,500 miles with an average of 24 mpg. It's a mix of city and highway, although the highway is usually full of traffic so I don't think it's too bad. Hope to take a road trip soon and properly test out what my highway mpg would be.

 

[Tamadrummer88]

This last tank according to the computer i was around 22.8. 1700 miles so far.

14mpg last fill up again lol

14mpg last fill up again lol

You are a good candidate for a road trip it sounds like.

Go do some steady cruising at about 70 and see how that changes.
I can't imagine daily driving a car in NYC.
When I lived in LA and worked downtown I rode a Bike in the 18 miles because it was faster than driving. NYC would be the same.

Averaging around 29 to 30 around town and back roads, no Highway driving yet.
