I live in the Pacific Northwest (Spokane, WA / Post Falls, ID) and I drive about 26 freeway miles each way to work and another 2 to 4 street miles a day. What can I expect for highway/freeway miles from the Prius. Thanks!
See This Post just 3 or 4 down from yours on almost exactly the same topic. In the PNW it may be a bit cooler and rainier and that will have a negative impact on your mileage.
In my experience, you should easily get at least 46-52mpg in your driving. I did a 52-mile round-trip from Santa Clara, CA to San Mateo, CA last weekend, averaging around 70mph on the freeway and I got 51.5mpg for the whole trip. About four miles of it was suburban streets. My average mpg is usually closer to 45mpg because I have a short commute, and that's most of my driving. I do not drive to get high mpg, but slightly faster than the flow of traffic (not enough to be excessive or draw attention to me).
I'd agree with PriusEnvy. Of all the things that hurt mileage, short trips are the worst. Most of my drives are 1-2 miles each day, and this negatively affects the mileage. I rarely drive into work (I ride a vanpool), but when I do it's about 26 miles (in Seattle in the PNW). With the warmer weather, I've been getting ~50 MPG on these trips, without any special driving (i.e., watching the MPG monitor) at all. (In the depths of winter, it was more like ~45 MPG).
Thanks for the feeback. I am going to retire my trusty Corolla CE that gets 35 to 38mpg so I want to at least beat that! Being that the A/C is electric, would that compromise economy when the weather warms up? Thanks again!
<div class='quotetop'>QUOTE(emtownsend\";p=\"73706)</div> Less so than in an old-technology car because the A/C doesn't require the engine to run. In Dallas I get better MPG in warm weather even with the A/C running all the time because the engine warms itself faster and runs more efficiently.
I just managed 58.7mpg with 75%+ freeway driving here in the Phoenix area - temps ranged from the 60's to the 80's F. Speeds ranged from 55-70mph. No major hills.
<div class='quotetop'>QUOTE(richard schumacher\";p=\"73709)</div> Other than the engine needing to run to generate electricity. The real savings with the electric A/C compressor is that it's variable speed, so it only has to run fast enough to keep up with the cooling load. I run my car with the A/C in Auto Mode almost exclusively and 50 MPG is my average on the highway (between 65-75 MPH and with hills) using the cruise control.
i did some testing last fall after it got cool enough to run without air conditioning and my results were 70 mph = 50.5 mpg 65 mph = 52.5 mpg 60 mph = 55 mpg now running the air ( i like it cool bout 68-69º) reduced those figure bet 1-2 mpg. for some reason, even on similar days, the mileage never seemed to level out very well. all the mileage figures were gathered on days when i drove at least 50 miles one way and encountered no major traffic issues. just to let you know, once i hit traffic due to an accident going the other way and got about 65 mpg averaging bet 25-40 mph WITH the air on... in fact it was one of the hottest days we had last summer with temps over 100º. in any other car i would have been fuming but my Prius was totally cool and collected. that was when i knew that buying this car was one of the best decisions i had ever made.
