Tested: speed vs MPG - 2006 Toyota Corolla automatic

While I was in Ontario over the holidays, I borrowed my dad's car to collect some speed vs. fuel consumption info.

I learned a couple of interesting things about the car...



Temperature was cool (-4C), and there was a breeze. I'll post the full details a bit later...

Raw numbers: (posted Jan 13/09)

Code:
E (mpg US) ... W (mpg US) ... Avg

53.5 ... 60.85 ... 57.2
47.5 ... 53.4 ... 50.5
45.8 ... 53.1 ... 49.5
49.2 ... 54.6 ... 51.9
45.9 ... 51.7 ... 48.8
40.5 ... 45.9 ... 43.2
35.0 ... 40.1 ... 37.6
33.0 ... 36.5 ... 34.8
30.3 ... 32.6 ... 31.5
Conditions, route & methodology (reposted Jan 14 from further down the thread):

Weather conditions: -4C, wind E 9km/h, pressure 103.32 kpa, humidity 68%

Route: 2 lane highway, straight, dry & almost level (11 feet elevation change over 1.6 km / 1 mi.) The road runs SSW/NNE and can be found here: iroquois ontario - Google Maps

Methodology:

Speed was set once per pair of bi-dir runs with cruise control, cancelled with the brake between runs. Car was brought up to speed & leveled off before passing a "start" marker (road sign) where the ScanGauge (not calibrated to this car) was reset. Reading was taken after passing a "finish" marker and cruise was cancelled.

Traffic conditions: There was no traffic in my lane and very little in the oncoming lane. (More than a few runs were done with me being the only car on that stretch of road.) If anyone caught up & overtook me, or if I caught up to another car, I ditched that run and did it again to avoid aero interference.
