40 mpg Prius vs 50 mpg European Diesel cars - Page 9

 

Yes, the figures for the hybrid are US gallons.  In the past year, my
lowest mileage for a tank of gas has been 48 MPG; the highest has been
52 MPG.  My highest ever was 53.4 MPG.  And except for the first two
tanks of gas, I have never had less than 46 MPG on a tank.

Were your lowest MPGs during the winter?  Mine were.  Other
than that I was always above 50, usually 52-ish.  This year my
mileage is even better.

 interesting, anyone know what causes better mileage in winter?

higher density of fuel due to cold?  not running a/c?  lower motor
winding resistance due to cold?

is this a common phenomenon?

is it true for non-hybrid cars, or only hybrid cars?

 

It isn't true for hybrid cars if you winter where the snow falls.

 

I'm not sure that hybrid vehicles get better fuel economy in the winter than
in the summer.  For conventional internal combustion engines, the air is
denser in cold weather so theoretically, the air-fuel mixture burns more
completely.  The engine takes longer to warm up in the winter so the
air-fuel mixture is enriched a little longer so in the real world, most
people tend to get better fuel economy in warmer weather.
