Got better mpg by driving without thinking

[Genoz World]

yeah! i just got 46.7 mpg on my last tankful - with touring rims and bridgestone G017 potenza's. accelerate, lift and chill at the speed limit. at optimal connection to your car, my best advice is to "FEEL" the battery,,,,,,,,a slight throttle action will cause the car to surge a bit, that's the battery, make the most of it without the ICE activating.

do all this and keep a "SAFE" eye on the consumption screen.

You think since jack-rabbit starts are bad, turtle-slow must be good. You think that if you keep the meters in the proper range 100% of the time, you'll get better mileage than if you anticipate -- something the meters cannot do -- and go out of the "proper" range. You might think that regenerative braking is magic, so use it a lot: it's "free" power. You might see that you're getting 100 MPG+ in EV mode, so use EV mode as much as possible... etc, etc.

I certainly fell for a few of these. The point is, the car is smarter than us when we're operating out of misunderstanding, but we're smarter than the car when we do the human part of the equation: anticipation.

A second issue is that the car naturally gets better mileage throughout the break-in period, so even if you did exactly the same things on the same routes, you'd end up with 5 MPG more after 1500 miles than when you first got the car.

In my mind, the people that get the worst mileage are: 1) those that figure they know how a hybrid works, but are wrong, 2) those that drive like maniacs and call anything else "blue-haired old lady driving", and 3) those who live in a geographical region/climate/culture that's stacked against good mileage to begin with. I fell into category 1 at first, but think I've improved.

Actually, I have gotten more casual about mileage and have played around with different ideas, and my mileage has slipped a bit over time, from my high point.

Hear, hear...All things in moderation. I've also found that anticipation yields the most rewarding results followed quickly (equally?) by conservative speed.

I really think the computer of the car will get you the best mpg for you without thinking too much while driving.

I own a 2010 Prius with Nav and Advanced Technology Package. Drive 40 miles to work north of Alexandria, Virginia using 495 Beltway and Baltimore-Washington Parkway. The ATM has a sensor above mirror which senses (left and right) where your car is on the road and Prius helps you steer the car/sounds alarm if you're far from center lane.
ATM has a (InfraRed ?) sensor at front of the car which detects (driver adjustable) distance to car ahead and relative velocity between car ahead. I Set Cruise Control 10-15 MPG above traffic speed and rarely touch the brake or accelerator while driving 40 miles. I generally drive faster going to work and achieve 46-50 MPG. Coming home is much slower, average 45 mgh, and achieve 51-54 MPG.

Note: 2010 Prius User Manual and Prius Repair Manual are both incorrect at not mentioning that if car is in Brake mode (and has not had drive lever moved to Drive) you cannot Set Cruise Control.

Normal as in none of the buttons activated. (so not eco or pwr). I guess "straining" wasn't the best word. But either way, it'd be nice to get the engine into its sweet spot to better climb the hill, wouldn't it? For this steep mountain climb up the coast mountains, I'd rather have it in PWR mode and let the engine rev freely then keep it in ECO mode (and have the computer restrict rpm)

I thought all the modes just modify the throttle response. And as far as I can tell that seems to be true. In other words, you wouldn't get more power from the car in PWR mode than in ECO mode. It just feels that way because you don't have to press as hard on the accelerator pedal.
