I've been averaging 24-26mpg in my 2013 ES350. Which I think is effing awesome, considering I drive mostly in town with a slightly heavy foot, maybe 1/3rd of the tank is driven at interstate speeds of 80 to 85mph.

That's pretty good at that speed. My 2015 gets about that at 70 mph. At 80 mph, it drops to 22 mpg. But 70 is the max. speed limit, in this state. There are very few areas you can cruise much above that. Even in the middle of nowhere. In town it's only around 20 mpg. So, your MPG might be close to what it was when new, I'm guessing? EPA ratings are 19-30-24 mpg. I haven't gotten close to 30 mpg on trips, yet. More like 25 mpg at best. But, as long as it's within averages, there's no real concern. Just as long as we never have to go back to 55 mph. These numbers are all generated by the computer. I have never manually verified the numbers by calculating miles driven verses gallons used. I have no reason to suspect they're inaccurate by Lexus. Unless these cars have an Oxygen Sensor that needs to be replaced like in Toyota's of the past at around 80-100k? That kills mileage, but the engine would also act up. What is the speed this car gets the best mpg? Probably around 40-50 mph. (That'll open up a can of worms).

I live in a rural area, and very little of my driving is done in stop-and-go conditions. About the only condition that brings down my fuel efficiency a bit is the very hilly terrain. The fuel efficiency with my 2017 ES is typically in the area of 32 mpg (actually calculated). When I do have to drive in more urban conditions, gas mileage drops to around 25 mpg. At this point in my life, my driving style is more conservative than it was when I was younger.

Fuel efficiency with my previously-owned 2013 ES was between .5 and 1 mpg better than what I get with the 2017 ES. I suspect that the difference is related to two factors. The 2017 ES has the all glass panoramic roof, which likely weighs 150-200 pounds more than does the standard sunroof that the 2013 ES had. I also suspect that the 2017 is a bit less efficient because it has more safety technology that consumes a bit more energy.

Around 21-22mpg for mostly city driving with a light foot. High 20's on the Interstate.

Not bad, but my previous LS430 with a V8 (and heavier than a tank) got around 19mpg for city driving. I would have though there would have been a bigger gap.

I get about the same, maybe only 20 in city driving and 30 on the highway. Very efficient on the highway, not so much in the city.

I'm glad though we don't have the new transmissions to eek out a little more mpgs. Lots of complaints about them clunking around with stop and go. Many longtime ES fans saying the hybrid is the way to go to avoid the 8 speeds. The new LS has 10 speeds?

I just don't think a car drives right once you go past 6 speeds. My first ES from the late 1990's was smoother and had about the same mpgs with a 4 speed. Blame CAFE from the feds making the carmakers jump through these hoops at the expense of consumers.

Around town in stop and go traffic I get around 24 mpg.. On long highway runs, running between 70 and 75, I will get between 30 and 31 mpg.

I agree with this. The 8 speed is so uneven when shifting at lower speeds, I think the surges probably use more fuel. The 6 speed in my 2013 was perfect, shifts almost imperceptible.

I have a 2016 ES 350 and normally drive in ECO mode and get around 26 in the city and about 29 on Hwy and feel there is ample power. Previously owned the GS 350 AWD and that used to give me 18 in city with Premium Gas so very happy with the mpg's.

BradTank

My experience with Eco mode is like <1 mpg difference. Just didn't seem to me to be worth it for the lazy throttle and supposedly the AC compressor doesn't run at full capacity. Can't have that in the summers here.

My other car is a 2020 Highlander Hybrid so maybe that is why I feel there is ample power even on ECO mode

The Toyota V6/6 speed auto combo is the main reason I bought the ES. It just drives so nice, no turbo lag, always in the right gear, doesn't clunk, lots of power, still gets good gas mileage. Maybe a bit too much power for a FWD car if you turn off the traction control and mat the throttle from a dead stop, it will shake/wheel hop the fillings out of your teeth lol.

Seriously though I thought about buying a Dodge Charger or Chrysler 300, with the pentastar V6(V8 cars were a bit out of budget unless you wanted a wrecked/beat/high mile car). The ES350 was faster, got better MPG, had a bigger trunk and more room inside than those barges. They did pack a bit more soundproofing in those cars, that's really the only thing I noticed that was nicer on those cars. Also my mom had a 2012 Camry with this same V6/auto combo, drove it to 180,000 miles and I think they replaced 1 wheel bearing on that car other than routine maintenance.

I drive in Sport mode all the time so that could explain city driving mpg only around 19. I love the feeling of the steering in Sport. I have a pretty light foot on the gas, usually. AC effects the mileage a bit too, but I'll never buy another car without it. One thing that makes Lexus and Toyota products most appealing is their reliability.

With both the 2013 and 2017 ES cars that I owned, I drove in Eco mode over 99% of the time. I never found a problem with the air conditioning in Eco mode, even on days when the temperature was 95 degrees or hotter.

I found that the key to getting the AC to work well and to cool off the cabin more quickly, regardless of whether I was using Eco, Normal, or Sport mode, was to switch the AC from the recirculate mode to the fresh air mode immediately after starting the car. On very hot days, when the car has been parked in the sun, the temperature inside the cabin can reach 135 degrees or higher. The last thing you want to do is to be recirculating air that is 40 degrees or more hotter than the air outside of the car. Switching to fresh air mode can help the car to cool off noticeably faster.

You can also open (tilt) the sunroof and pull the shade/cover until it is only open an inch or two. This helps vent out the hot air until the cabin cools down, then close everything up.
