Short story : totally failed, but permitted me to learn.
My result is the following :
| trip |
km | L | L/100km |
miles | g | mpg |
conditions |
| way up |
203.2 | 9.8 | 4.823 |
126.3 | 2.589 | 48.78 |
6-4°C (42-39°F) - humid (>85%) - 30km/h (18mph) head wind |
| way back |
213.5 | 11.1 | 5.199 |
132.7 | 2.933 | 45.25 |
3-1°C (37-33°F) - raining - 30-60km/h (18-37mph) side wind |
| challenge |
416.7 | 20.9 | 5.016 |
258.98 | 5.52 | 46.9 |
With this raw result I lost
but what's if...
- I would have taken the highway :
| trip |
km | L | L/100km |
miles | g | mpg |
note |
| highway |
452 | 22.1 | 4.9 |
281 | 5.85 | 48 |
| realistic highway |
452 | 26.7 | 5.9 |
281 | 7.05 | 39.9 |
On such road (mountain) I would have done more than 6L/100 (less than 39) so I use my Combined EPA as reference |
| virtual |
452 | 20.9 | 4.62 |
281 | 5.52 | 50.87 |
Highway distance with real consumption |
| Saving |
. | 1.2-5.8 | . |
. | 0.32-1.53 | . |
5% - 22% ie EPA+6% - EPA+28% |
Even in comparison with the unrealistic Highway EPA, I would have saved (a very little) gas
In comparison with a more realistic EPA and my old habit to take the highway at highway speed, I saved 28%
- I would have driven a prius on the highway :
A prius generates 104g/km of CO2, which corresponds to a diesel consumption of 3.91L/100 (60.2mpg)
| trip |
km | L | L/100km |
miles | g | mpg |
notes |
| prius |
452 | 17.7 | 3.91 |
280.9 | 4.67 | 60.2 |
| saving |
. | -3.2 | . |
. | -0.85 | . |
-18% CO2 |
So I generated 18% more CO2 than an average driver in a prius.
Well, not so bad for such conditions (mountain, humidity and wind)
If I can graph the altitude then I'll post it.
