Fuel economy on a hybrid gets so much better in hot weather - so I decided to see what would be the most I could get.
I did mostly non-highway driving, ~20 miles average per trip, minimal AC use, almost 100% regenerative braking, ECO mode.
The light turned on at 660 miles and the "distance-to-empty" stopped working at 680 miles. So I gave up and filled it up at 711.2 miles. It took 14.109 gallons. Since the tank capacity is rated 17.0 gallons I guess I could have made it to 850 miles in theory.
711.2 miles / 14.109 gallons = 50.4 mpg. The built-in calculator was close and showing 49.5 mpg.
This is impressive. I wonder what tires you have on the car. When I switched from Bridgestone Turanza to Michelin premier A/S my fuel economy dropped a bit. With careful driving I was able to get around 45mpg on a tank with the Turanzas. But with the Michelin I could get maximum 42-43 mpg.
bc6152 - note that the MPG is rated better in the City "40" than the highway "39" because of the
regeneration from slowing down.
My best in our 2014 ESh was 43 in the summer, kudos to OP for the superlative discipline to achieve
those results. Our 2018 ESh only has a couple thousand miles on and is just now breaking into the 40's.
We drive almost all city about 20 miles each way but on a road trip in the '14 discovered that the MPG
decreases markedly the faster you travel. Was getting low 40's when commutating that dropped down
to low 30's (!?!) when driving 75 MPH for a couple of hours. Slowed to 65 MPH for the next couple
hundred miles (damn near killed me!) and low and behold, the MPG went back up to almost 40.

Ahhh. I didn't know that. It's actually the reverse of what we knew previously. I have a 350 so am unfamiliar...

I'll have to agree 100% with you. I have a 2014 ES and I've discovered the same. About 60-65 is the sweet spot and I get 38-40 MPH. Going 70-75 MPH (most interstates) and I get low 30s also. Ha!
Yes the ESH hybrid system achieve better fuel economy in city driving. The way to get in the 40s mpg is to drive mostly in the city, not much traffic and idling. Better if your trips at least 30 minutes or more. temperatures outside not cold but not too hot either. Not much load in the trunk and not too many passengers in the car.
I agree, that is excellent, even incredible mileage. I haven’t seen that kind of mileage since we owned Priuses.
For those of you unfamiliar with the hybrids, the mileage goes down at highway speeds where there is less assist from the electric motor. I just returned last night from a road trip. I was in fairly heavy traffic so I couldn’t really do anything but roll along with surrounding traffic, thus I averaged 75 MPH. I was in Eco mode but running the air conditioner normally (it was 100 degrees F when we rolled back into our garage). Bottom line, I just drove normally and enjoyed the ride. I averaged 38.2 MPG on the trip, using Ethanol fuel blends. For highway speeds, I consider that pretty good with this particular drivetrain, but I have seen some of you get very close to that number on the road with your ES 350 vehicles. City driving is definitely where the hybrids excel, and that is 90% of our use.
This is impressive. I wonder what tires you have on the car. When I switched from Bridgestone Turanza to Michelin premier A/S my fuel economy dropped a bit.
I have Michelin Primacy MXV4 on my ES300h. The pressure is 40psi in all four. There is only minimal amount of tread left on the tires so that lowers the rolling resistance as well I guess. This may have explain you drop in mpg as well since the new tires have much more rubber to bend and therefore create more resistance (compared to the old bald tires).

One thing to consider is that the Michelin Premier tires are not rated as low rolling resistance tires. The Michelin MXV4 and MMX4 tires that have been standard equipment on some 6th Generation ES cars are rated as low rolling resistance tires. I'm not sure about the Bridgestone Turanza tires.
Whether or not tires are rated as low rolling resistance tires can typically account for a difference of 1-2 mpg of fuel efficiency.

Agreed. The Michelin premier have smooth ride, and good grip in wet conditions, and snow but the down side is the rolling resistance is not low. But I like the tires. I am willing to sacrifice the mild drop in fuel economy for the smooth ride and better handling. Maybe the primacy are better fit. But I have no experience with them.

good to know. maybe my next tires will be the Michelin primacy or the Pirellis P7plus. Also the tire pressure is very important. If you don't care about a slightly rougher ride and you want to boost the fuel economy you have to go above the recommended 33 psi. I have mine at 37.

711 miles on a single tank, 50.4 mpg.
