Just picked up my '22 ES300h on Monday, dark blue/black luxury. The dealer I purchased from was in Raleigh, NC and I live on the NC Outer Banks. So I had 3 1/2 hours on the way home to get to know the car. I saw 41-42 mpg at 75, then reset the mpg reading and saw 43-44 when I dropped to 63 mph for the last third of the drive; about what I expected. I'll see where the fuel milage settles as I put more miles on it. I also turned off the lane centering and prefer the old fashion cruise control verse the radar cruise. This is my second ES, the first being an '07, with a '14 MB E250 Bluetec before the 300h. The ride is well controlled, although not as firm as the E Class. Definitely quieter. The ML sound system is great! Love the dark blue metallic in the sun shine. All-in-all pleased with the with the first 500 miles.

PS - My son drives the 07 ES and has over 260K on it. The car has been bullet proof.

 

Get into the LTA settings and change the Sensitivity from the default STD to HIGH.
I have found that this reduces the oscillation effect we've been discussing here.
Because I use the Dynamic Cruise at highway speeds I assume SunilP and most of
us do also. For those that do not, please turn on the cruise (whether you engage a
speed or not) which gives the LTA and additional input.

 

I will have to give that suggestion a try. Thanks.

 

Essentially I find LTA/LCA w/ cruise on helps w/ fatigue. I just wish you could adjust the radar sensitivity to something way less sensitive. it sees a car a mile head and it applies the brakes very firmly. that's the thing that really deters me from using radar cruise. the car behind you then gets annoyed like why are you braking.

 

When you take your hands completely off the steering wheel, doesn't it give you a warning and eventually shut the feature off?

 

Great tip on the sensitivity setting, thanks. I think I'll try that.

 

Also worth mentioning here: A big source of the great gas mileage in hybrids is the energy recaptured when you decelerate. That happens a lot in city stop-and-go driving, which is why hybrids can sometimes get even better MPG in the city than on the highway. Highway cruising, unlike traditional gas-engine vehicles, actually isn't the ideal economy mode for a hybrid car. But since we're conditioned by a lifetime of knowing that highway mileage should be the best mileage, seeing otherwise understandably clashes with our expectations.

 

Oddly, this is my first hybrid that has better highway EPA rating than city. All of my previous hybrids and even our 2021 RX have just the opposite balance, with city mileage rating a little higher than highway.

 

I wonder if the ES's excellent aerodynamics are a factor in that. Most SUVs and econoboxes have a lot of drag at highway speeds.

 

It may well be the case that the ESh is capable of getting better highway fuel economy than is its city fuel economy, but I doubt whether the EPA rating is based on "highway" driving at 75-85 mph, as the OP of this thread was driving when he/she was disappointed with the fuel economy.

 

if you leave your hands off for too long I think it will disable but I usually touch the wheel enough to keep it enabled.

as someone else mentioned you do have to have the cruise control turned on before the actual lane centering works otherwise you will ping-pong between the white lines as the feature that prevent you from going over the white line is the only thing active not the Actual Lane centering.

 

I did not think of it that way, it's a good perspective. I did an oil change at 1000 miles, so that might account for the better than average MPG.

 

No, that was meaningless in this case, and completely unnecessary.

 

Well, that debate rages on. To each their own. It was free in addition to my 5000, and 10000 services. So no harm no faoul.

 

Crazy, no free oil changes up here in Canada. I get my '22 ES300h UL next month (fingers crossed).
