Poor mileage

You are getting 560 km / 39.7 liter = 33.2 MPG in city driving. According to Consumer Reports, 2010 Prius gets 32 MPG city and 55 MPH highway. So, what you're seeing is normal. Gen III Prius excels in highway and rural driving but it's so - so in city driving. You should have got the Gen II Prius if you were primarily doing city driving, which had 35 city and 50 highway according to Consumer Reports.

So, all is fine, especially in the cold-weather conditions of Canada.

(By the way, ignore the EPA MPG ratings -- they don't mean much. The CR MPG ratings are a much more accurate description of real-world driving.)

I disagree that the Prius gets 35mpg city blanket statement. The Prius excels in city mpg unless you make numerous short trips. This sounds like the reason for the case above. Short trips combined with wet, cold weather and a new driver.

 

Hi All,

Consumer Reports does their testing in Connecticut. Which might be close to Vancouver. The terrain in Connecticut is hilly, with a short perodicity. The roads wrap around, and go up and over the hills, with many blind curves and consquently stops. If this matches the terrain that your driving in Vancouver, then the CR results are a good metric to compare against.

Getting better mileage on such roads is difficult. But you probably, through experience (route selection, trip timing, hypermiling on-road techniques) improve your mileage to around the mid 40's, if not better. Its not simple, however, and the circumstances of each trip need to be disected and thought thru from a mileage imperitive. This is the kinda thing that Wayne Gerdes over at CleanMPG.com is very very good at. You might want to check out that web site.

 

Are you sure you have the numbers correctly and not reversed. I thought Prius had higher MPG in city vs hwy (mine certainly has with ~55MPG city vs 45 Hwy).

 

First excessive warming up and using full blast heater in the car is the very detrimental to your MPG. Also, gentle driving will not get you better MPG. Search for pulse&glide driving style.

 

fill out the questionaire so we can have a look at your unmentionables.

 

Nope, Gokhan doesn't have his numbers reversed. See my earlier post for what CR got in their tests. Just because the EPA tests show higher city numbers than highway doesn't mean that's what you'll get.

 

I clicked the link and looks like CR got those numbers indeed (unless they made a mistake). The only way I could get 32 in city would be by flooring, driving 1-2 miles, and in freezing weather. Yet, I could not get more that 45 MPG in highway driving at normal speeds of 70-80 MPH.

 

Cold weather kills the mileage. Driving 70 - 80 mph is not likely the whole problem, but how long it takes to get to that cruising speed may come into play... Sounds like your a pretty agressive driver.

I'm getting about that just driving back and forth to train station and not letting the car warm up. When I drive further it gets back in the 40 - 50 mpg range... but I've been getting over 400 mile on 9 gallons (once 500 but who's bragging)

 

letting the car warm up in your driveway wastes fuel. dress warmly and start driving right away. gently for a few minutes if you can. keep the heat as low as possible as this forces the engine to run more than it ordinarily would unless your going steadily over 45 mph or so. using the electric seat drains the battery and slightly reduces mileage. accelerate smartly from a stop to a little over your desired speed, then ease off the pedal and coast until your a little below your desired speed and keep repeating. this is pulse and glide. i'm getting 49 mpg right now on a 14 mile round trip commute (7 each way) down from 65 in the nice weather mostly due to te cold. all the best!

 

Winter temperature plays a direct and measureable effect on the mileage of my daily commute. I drive 208 miles round trip daily, all but 16 miles on the highway averaging 77 mph and mileage will drop to around 39 when the temps dip to the 20s-30s. When the temps rise back to the mid 50s-60, mileage will go up to 44-45 without fail.

 

I drive today at -12Celsius in Sherbrooke QC (-17 last night) and I get 38MPG or 6.1l/100km. My car has 8,000km and the city is full
of steep hills . On the highway I get 5.2l/100km.

In the summer I get 4.3l/100km in the city and 3.9 on the highway but I never go faster than 100Km per hour unless I am on a flat surface. I keep it in Eco mode all the time and it is perfect for the snow and ice with my Blizzak 15in tires filled with 35psi in front and 33psi in the rear wheels.

You seem to have a bad consumption for Vancouver WHICH is not as cold as here. My fan heater works well in the Winter but I do not have heated seats.
