Not quite 2 weeks old and 2nd fill up later only getting 33 MPG eventhough display is showing aroung 35+. I coming from a 2000 Toyota Avalon that got me avg 25 MPG with a 210 hp V6. It was really hard to make the change and I expected to avg ~36-37.

720 miles so far and I am enjoying the car. However, I am having an incredibly hard time keeping the EV engaged @ 25 mph The slightest touch to the peddle and it cuts out. but if I don't keep on it I start to slow down. The 2 and a half miles to and from the highway on the way to work are killing me.

I am mostly highway ~ 45 miles round trip daily with 40 on the highway and cruise set at 70 mph. no problem maintaining speed even on incline although not very steep but steady. I am trying not to focus too much on the hybrid part and drive like I normally do. I have very high hopes/expectations for this car.

'69 Mustang Mach 1 351W - 20 MPG highway /avg 16 and no moss growing on those wheels
'89 Nissan Sentra - 41 MPG highway - 4 speed man
'94 Honda Accord - 35 MPG Highway - 5 speed man
'00 Toyota Avalon - 33 MPG Highway - 25 avg

I know how to drive to get good mileage, I am afraid this is making me a grandpa way to soon to achieve better mpg. I am looking forward to the first road trip to see if I can come close to the 600 mile range

This was the first car I drove that came close to matching the quietness and smoothness of the Avalon. Overall very happy with a little buyers remorse, I just hope it gets better after the engine breaks in.

Does the chug-a-lug when the engine is cold get any better?

I could be wrong but I believe the chug-a-lug is because the vapors burn first. Some PZEF cars like the new Subaru Legacy PZEF do this too, part of conservation. The dealer warned me of it and it seems to be the same symptom in my sonata first thing when cold.

Your mileage will improve with break in, with steady gas pressure in blue mode, use of cruise at 35+mph in relatively flat areas, and coasting paired with anticipation of long downhills or impending stops. it may mean a slight change in driving habits but it makes a difference in gas and very very little in time lost.

Ian,
I am pretty new to the Sonata Hybrid. But, one thing I have learned from the short time I have been on this board is that your goal should not be to get EV on all the time. Just keep the gas pedal constant, and let the car do the deciding when to engage EV

Absolutely right, and thanks for adding that in there, I'd forgotten to mention it above. The reason to conserve electric in the city is to allow for standing starts on EV for longer distances, reducing consumption of gas to get up to speed. With a 1/2-3/4 charge, you can get through the first three gears or so with a moderate acceleration before the ICE kicks in.

Absolutely right. Don't try to outsmart the car. It goes in and out of EV for good reason. The engineers programmed the system for max efficiency. Once I stopped trying to make the car do what it didn't want to do, my mileage went up. No problem keeping it over 40 MPG now.
The car is smart. Just drive smart and let the car do what it needs to do.

Thanks all for the information. I am trying to get used to the feel of the accelerator. Lot of years of driving behind me, so I kind of know how it should feel. I tried a little experiment this morning on my way to work and turned blue drive off when I was on the local roads (25 mph or less) and then put it back on when on the highway. I found the car much easier to accelerate when under 25 mph with blue drive off. I found it much easier to keep control of the car and speed without feeling like I had to push harder on the accelerator to maintain 25. I still slipped in and out of EV but it maintained EV for much longer durations. Also the Intant mpg never dipped below 30ish. With blue drive on I was constantly dropping below 25 on the impg just trying to get to 25.

Just my impression, but I feel like I need to apply more pressure at lower speeds to get the car to respond. I am not trying for jack rabbit starts and my drag racing days are long behind me, but I would like to not be beaten by a bicycle If I wanted a scooter, I would have called the scooter store and gotten it for free

I do drive 70mph on the highway with cruise control and at anything above 40 MPH I think blue drive does an excellent job of maintaining the car and speed. Anything below 40 and well I feel like it is a lot of work moving that pedal. I will try my little experiment for this week and see how it goes.

Thanks again to all I look forward to your stories as well.

The Blue Drive requires you to press further into the gas pedal (more travel than a normal car), but it means you get finer sensitivity, i.e. you can control the eco gauge on the left far easier. It means you get much less peppy starts (it's a sedate acceleration instead) but you get better conservation. The "Black" drive means that you get more responsiveness and more use of combined EV+ICE but it is harder to control the flow of power and a smooth and steady pace, which is how you'll get good numbers in city driving. I used to drive only in black mode for familiarity. Now I only use it if I'm in a real big hurry, or I need some power right now. You'll develop a new driving style for this car that won't be quite like how you drove a standard gas car, but I don't think it's such a bad thing.

And that is the problem . But a problem that - I think - many of us faced when first driving this car. First several tanks, I got at best 28 MPG since my driving was close to 80% city driving and trying to drive this car how I drove my previous cars was bad, bad, bad. Once I started to keep a more constant pressure on the gas pedal, NOT tried to keep EV mode engaged and was content to not try to pass everyone (the hardest part for me :-> ), my MPG has been near 35-40 consistantly.

My wife, who is a much more conservative "laid back" driver....content to drive the speed limit, slows down to the speed of the person in front of her instead of always passing them if they are still close to the speed limit, etc. does even better on the MPG. We filled up and drove several miles back to the beach house we're at here in the Outer Banks and when we got out, the instant MPG read 52.9 MPG... Made me sad that I couldn't get close to that on more than a coast down our driveway :-).

Actually that's not the problem. If you take a look in my original post for the cars I have owned and then check fueleconomy.gov, you will see I was exceeding predicted ratings for every car I have owned. I have been doing "hypermiling" techniques long before there was a hybrid car. Simple physics when you think about it. A body in motion, stays in motion. It takes more energy to get the car moving than to keep it moving.

I have been driving this fill up with blue drive off on local city streets and find that I have better control on the gase pedal in these situations. I turn blue drive back on when on the highway and use the cruise control. I just hit 300+ miles on 1/2 tank of gas which is better than I have achiieved so far. Also for the first time the avg mpg is reading 36.5 when I have never even hit 35 on the 2 prior fill ups. With blue drive off I have greater acceleration control on local streets and notice that I can usually keep the iMPG above 25 when I accelerate. I think another week or 2 and I may have the hang of this. I was hoping to average 37 MPG overall so if I make that or better it will be great.

I did tell my brother that this is not the car for his lead footed wife. I don't think she would be able to adjust.

I am on the east coast hope all of you are safe as hurricane Irene comes ashore. Just starting to get hit with the rain now. If only I had cleaned out the garage.... Be safe!!
