Coast/stay off the gas as much as possible when no one is behind you. You'll crawl to wherever you need to go but the MPG will be....well...still horrible.

I'm up to a whopping 25 mpg for a hundred miles on this tank of gas!

That's my secret too, having a steady foot on the pedal works magic. I barely use the cruise control unless my foot gets tired, but my wife doesn't understand the trick. Her foot is as heavy as a lead brick. 😑

It takes a lot of discipline lol.

 

[2023 GT Steel Gray]

27 years hoping to see the fruit of that 'discipline' and I still don't see it. It's a lost case. 🤯

Our '16 has a weird cruise control, never saw one like this: on downhills, it will downshift to slow the car
Then revs go up
I disconnect CC downhill and on steep uphills
Yes a steady foot helps mpg

The best thing you can do is to have the instant mpg display up. It is amazing how just the most tiny lift of throttle can take the instant mpg from 30 to 50mpg.

The secret is cruise control. I use it whenever possible. I also try to stay in as high as a gear as possible (MT) when not "having fun". I call it my own personal "eco mode".

My average mixed driving MPG (with more than a few jackrabbit take offs) on my 2010 Koup SX is around 9l/100km (26mpg), but on long drives, with the cruise set, even at 125 km/h (~80mph) I can get as low as ~6.7l/100km (35mpg).

I personally find the instant MPG display completely useless.

I've heard from multiple different people that the real "secret" is to keep it under a certain speed and your MPGs will go up considerably. For example, do 105 on the freeway instead of the 120-130 most people do.

Even after I fixed the steer wheel angle sensor "clockspring" the cruise control still don't work. It lights up green & I pretend I'm on cruise control. When my koup SX was working😂🤣😂🤣🤣

Around where we now live i'm averaging about 28mpg around the 'burbs, and well in the 40s on the highway

I'm not sure of the North American-spec GTs but over here they have a Speed Limiter function as well as the radar cruise - the RC I find to be infuriating in anything other than light traffic, so if the freeways are reasonably busy i'll just use the speed limiter and I don't need to focus on either my speed or what my right foot is doing, which helps significantly with fuel economy

Try to manage your shifts before 1500 rpms. If you can get to 6th under 2500 rpms, you'll see a good mpg. I've been driving for 50 years and still pretend I'm running 1/4 mile sprints from some redlights. Just depends on what's beside me raring to go! LOL I'm averaging around 30 mpg around town and out on the interstate or open highway, 37 to 38. If I drive the speed limit, it's closer to 40.

If you want to go extreme.. The best place to find the most accurate info is on a Prius forum... thousands of topics about this.. it’s all they talk about. Or just follow one on the freeway, see how long you last before thinking about suicide.

 

[Larry48]

Yeah all the hyper mile crap, etc. I'm good with reasonable mixed fuel economy of around 31 mpg. I don't need to wring out every last mpg.

 

[dual-clutch]

I'm not getting anywhere near 31 on the tank. I'm getting 22 average. But that's all driving around town, stop and go.

 

[Larry48]

I have a 2023 GT-line, it's what it's been getting mixed town / highway. It's about a 50/50 split for my commute.

I’m just curious, when you fill your tank what does your Miles to empty range say? Mine is usually around 390

 

[dual-clutch]

I fill up at a quarter tank. About 85 miles left for the range.

 

[Steve g]

But what does it say when full?

 

[dual-clutch]

But what does it say when full?

Oh. It recalibrates to about 360.

 

[Hamster-GT]

Oh. It recalibrates to about 360.

The variance is pretty wide. Mine reads 410-420 when fueled up.
