Hypermiling (Gas Mileage Feats!)

mkaresh

Here are the gas mileage numbers people have posted for the Prius:

Real-world Toyota Prius gas mileage

Non-members see only five results per powertrain. I logged in and filtered results for "ultra-light foot." Looks like about 52 MPG if you're easy on the gas, though radical hypermiling techniques might bump this to the 70 you mention.

Ran the same filter for the Z--only two results with an "ultra-light foot" for all model years, both for a 2003. One 100% highway tank good for 33.3, one suburban tank that yielded 24.5. So it seems that very few Z drivers are keeping their foot out of the throttle.

27.5 mpg, (first half tank). mostly freeway, drive about 75-80 (flat though).

All of the above mileage is great if you live in a warm weather area........ As a past owner of an 09 Toyota Camery Hybrid I was very disappointed with the mileage. Toyota told me what this car would get in mileage. Wow I thought..... Last year when winter came to the Midwest the mileage dropped dramatically from what it had been........... I didn't know what happened so I went to my dealer for some answers!!! With a chuckle my service advisor informed me that they all do it when winter comes.... To say I was a little pissed is an understatement. So the GREEN cars are not as green as they are made out to be...............

Good point. The survey includes a question on air temp / AC use. It's not currently possible to filter results by this variable, because it's not a major variable for most cars. For hybrids, though, the battery pack's capacity goes down with the temps.

I Get 36 MPG by accelerating very slowly, doing 65 on average. I go slowly up hills, slowly accelerate coming out of the crest of the top, then popping it out of gear, and gliding down the hills. Near the bottom, I pop it back in and slowly apply gas. You will find that by coasting, giving yourself room, and not having sudden changes in speed, that you will get great mileage. Everyone passed me today doing about 70-80mph, but they probably also get 15 mpg (the big SUV's probably get 8-10). People don't realize what they waste in gas. It took me about 6 minutes longer to get to work by driving about 5-10 mph slower than everyone else.

If you want to save money, slow down and don't drive aggresively. If you were riding a bike and peddling, you know you work harder to go up hills, so slow down a little bit up hills, and glide down hills. Same principal. Just like with "constant" speeds.

Also, stay with higher octane gas. What you save in lower octane, you waste with less fuel efficiency, not to mention the car drives like crap.
