29.8 mpg? That's it?

I don't know HOW you managed that number. I've never managed to hit anywhere in the 30s, and if I end up ANYWHERE in the 40s, I'm not happy.

I do have a Gen II (2008) though.

I manage to get 49 mpg going up and down the Ozark mountains, hitting some of the hills at 70 mph. Hard to believe someone actually gets less than 50 mpg in these cars on a straight or just level road. Stop and go traffic and I'm in the 60+mpg.

42 is consistent for mine at almost 6k miles.

It's easy to do if you reset the MPG indicator then proceed to drive like an idiot for a short distance. Over the full tank though the number will creep up to the high 30s or 40s once you start driving in an appropriate manner again. Unless you just live in a really MPG compromised area. In that case you're just screwed. lol

I have almost 700 miles on my 2010 Prius. I've been commuting to work through Manhattan 5 days a week and my total average MPG is 43. I am not surprised by this because my average MP Hour is only 10! This tells me that bumper to bumper traffic is not where Prius excels. It's still better than most, but you may not get to 50 MPG.

I must disagree. Relative to traditional cars, the Prius really shines brightly in these conditions. Your MPG is down only slightly from what a Prius can do. A regular car, which starts at half the MPG of a Prius in flowing traffic, suffers a proportionately worse hit in stop-and-go.

In traffic jams, the Toyota and Ford hybrids outshine anything that isn't purely electric.

The few traffic jams I face are opportunities to increase my MPG, further widening the gap between Prius and non-hybrids. But not all congestion is created equal.

I just averaged 27 mpg. I filled up my 2010, zeroed the trip meter, then drove 15 miles home. However, home is almost 2000 ft. higher than where the gas station is!
Second tank, 46.5 on the first and 45.5 on this last one; a little over 300 miles on each fillup. Of course, there's break-in and it's been cold - well, California cold anyway (37 degrees F at start up this morning). The computer says I'm getting 47.5. I've been using "normal" mode. I haven't used the AC.

Hello Fuzzy,

Its true - other cars can't compare to the Prius. But I think that in the type of bumper to bumper traffic where you can only average 10 miles per hour, two things will happen: you will constantly rely on the engine to recharge the battery and you won't get much benefit from regen breaking. This is why I don't think this type of driving represents the ideal condition for a Prius. If it was, I'd be getting 50 mpg. I'm still happy to get 43 though.

One thing I noticed during a long stop and go traffic jam was that I saw my MPG went up until the battery went down to two bars. And once the battery went down to two bars my MPG started falling down fast. So I had to accelerate and brake a few times to charge up the battery little bit and after that MPG started going up again. So, I think it shows you'll do better in stop and go traffic for a while but if it's too long and when your battery's low, your MPG will decrease fast. But in overall I think Prius gets better MPG in slower traffic than in high speed highway traffic.

I have been getting around 50 mpg with my 2010 Prius II since I picked it up 8/31/09. Use the ECO mode mostly, have a 13 mile commute, plug in the block heater to get the coolant temp up to 85-100 when I start the engine on cooler mornings. Got only 46 on a 200+ miles drive into the wind and rain, then 55 on the ride back, with the wind and a sunny but cool day.
I agree that the 10 mph speed is not ideal - 45 to 50 steady seems good. My wife's 2007 Prius gets better than mine mostly, large due to her commute - a few miles longer (more time with engine at normal operating temp) and a 45 mph speed limit with few traffic lights.
Just my thoughts - Tony
