Eco vs normal mode - test results
Over my 25 mile commute, I decided to test the fuel efficiency (FE) difference between normal and eco mode. Last year, we did a poll and over 90% of drivers responding said they use eco mode exclusively, including me. These results are based on about 500 miles of driving about 20 commutes. Exactly the same route every time.
Eco mode average: 4.7L/100km or 50 mpg/ 14 celsius / 57.2 km/hr ave speed
Normal mode: 4.8L/100km or 49 mpg/ 16 celsius / 59.7 km/hr
The FE results are surprisingly close. I personally thought there would be more than a 2% difference. Another surprise is that I actually drove faster in normal mode even though I didn't try to. I certainly feels faster and more fun. Actually, I enjoyed normal mode more. I looked forward to the commutes when I put normal mode on. The best commute was 4.4L/100 or 53.5mpg and that was done in both modes, so no clear winner there either. Only a couple days had the a/c on so I'll continue with that to see if the more aggressive cooling of normal mode will take a toll on FE.
Overall, I'm a little surprised by the results and will switch to normal mode as my main driving mode.
