37.0 mpg for 2.5T AWD on Highway Trip.

[WRXtoStingerGT]

I've hit over 30mpg on the highways in my 3.3 when enabling coasting in eco-mode

Seeing 27-28 highway with the 3.3 , around 21 mixed city/highway [which means upper teens city]. I always turn off the stop/start when I get in, so the 1 MPG that might afford me isn't reflected in that number.

I'd like to see a LONG roadtrip that consumes a full tank of gas, returning over the same roadway (to account for any elevation and wind change/loss in either direction), at the same speeds. 37MPG isn't realistic for the 2.5L , the 31.5 MPG result is closer to reality. None of the car computers do a good job estimating on only 3-4 gallons of fuel. They need a healthy sample size to be at least ballpark close.

That will be the best way to measure the real world fuel consumption. While it's really rare to drive that far for the sake of finding the consumption. The full tank of fuel for the usual route will do for most. I do reset my accumulated drive after every refuel. Keep an eye on my consumption. I usually get between 24-29 MPG for my 3.3 which is very good even though my daily commute is around 75% highway.
Now I'm planning to visit a friend in 2 weeks time and he happen to be around 350 miles away from my place so I will be doing that round trip calculation. I'm not yet to decide the date but it should be early October and staying for few days there then back.

Last refuel, car indicated ~360 miles to empty. Previous fillups have been 400+. Doing the math, mpg comes out near what the car's computer shows for since refueling, ~26 mpg. But the DTE suggests I didn't get a full tank of gas and the mpg is actually lower (more city driving this time). Next time I refuel, I'll stop it before I think it's full then manually squeeze at a much slower rate until it clicks off. Also, after only 60 miles of driving (mostly hwy too), it shows ~1/8 tank used.

I've left my trip2 meter untouched for a long time, so that's been my gauge for overall fuel consumption rate if I don't intentionally get out paper/pen and calculate it later. The 22.2 is mixed city/highway, not a lot of highway since no recent trips in those 2300 miles. I believe the 23.2 is lifetime, being higher because I had some longer highway trips early into ownership of the car.

Again, this is just posted here for reference comparing 3.3TT results to the 2.5T .

My 3.3L showed 32.2 yesterday after a drive from c. 4,500 feet to over 10,000 feet (Uinta mountains), and back: a little over an hour each way. Frankly, I'm disbelieving.

My 2.5T gets almost 23 mixed. I must really be letting it eat compared to you guys lol

I've been doing a lot of long highway trips for work. So for 3300 miles since new, I'm at a lifetime average of 27.4 mpg. It's not unusual for it to be in the mid 20's for city and fun driving though.

Pure highway, warmed up, keeping it ~70mph.

There are some heavy footers (?) out there...

Gasoline consumption: Kia - Stinger - Spritmonitor.de

Overview Kia, Stinger

www.spritmonitor.de

(is in l/100 km)
Anyone knows of other such sites?

I would assume people don't get a Stinger to drive like grandma. Other than MerlintheMad, of course.

I have to travel 400 miles to a place where I can have fun. Chi traffic is almost as bad as southern CA. Only difference is roads are better in CA. I did see 3 digits on the speedo the other day

Kris, there's Fuelly - Track and Compare your MPG .

In my 3.3 I got about 22 MPG combined on my road trip of just over 3000 miles. This was with around 1000lbs of passengers, plus luggage, a roof rack and a cargo box. Highway speeds were between 70 and 90. I can touch 30 MPG by myself in SMART mode doing the speed limit on my commute, but that's nowhere near what the 2.5 folks are seeing

 

[Dan00Hawk]

Just did another Chicago area to Milwaukee area trip. This time with the Air Conditioning on. Didn't use cruise at all, and used either Smart or Eco mode. 102 miles, averaged 35.7 mpg with AC on. Mostly between 70 and 80 mph, often following other vehicles no closer than a "1 Mississippi, 2 Mississippi" distance. Picture from when I started slowing for my exit...

I typically like to drive around 85 mph on these trips and maneuver around slower traffic, but that drops the fuel economy quite a bit.

I rarely use eco. Does it really make much difference?

It does on mine. I usually can't get much better than 22-25 hwy mpg in Sport.

ECO certainly makes a difference in mixed suburban driving, about 2-3 MPG over a tank. SMART makes for a much more responsive vehicle on the highway.

I understand why the car won't stay in SPORT when you switch it off, but why not stay in SMART when you've shut the car off from there? It seems to provide the best blend of drivability and economy.

Glad to hear it makes a diff for the 3.3 crowd.

Any feedback from the 4 banger crew?

Given how much I drive (or don't drive), 1-2 mpg isn't a whole lot. I fill up 8-10 gals twice a month or so. I'll have to read up on smart mode. I think on the 22+ it retains that between shut off cycles.

On my 22 GT1, the car only retains ECO, otherwise defaults to COMFORT after a shut down.

 

[JSolo]

^^You're right, it just applies to eco mode, not smart - p 5-62 of the '22 owners manual. It reverts back to comfort mode.

 

[Dan00Hawk]

My observations on the 2.5t: I don't like the lack of throttle response in ECO, so I only use that on the highway. SMART does a nice job of acting like ECO on the highway to allow coasting when off the throttle, but reverting to probably COMFORT if you need to give it some gas to pass. Supposedly SMART switches between modes on it's own in the background based on driver inputs. SPORT most definitely keeps it in a lower gear for longer, and is more eager to downshift, which is great for enthusiastic
