57 mpg @ 80 mph!
1 Attachment(s)
I did a high speed test on the freeway, I was very curious to see how much I would consume at high speeds. I used my usual method: filled to the top manually between 2 tolls and weighed what I filled after the test.
I drove always at 130 real km/h (133 speedo) except a part that had a PSL at 110 km/h. The average speed is 128,5 km/h (GPS recorded). The fuel consumption is 4894 g = 5868 mL Distance : 141,75 km Result : 4,14 l/100 km at 128,5 km/h (56.8 mpg at 79.9 mph) The car is rated officially at 4,9 l/100 km at 120 km/h (48 mpg at 74 mph). I am very pleased with this result and I have yet to do 3 more aeromods: lowering, kammback and belly pan. http://ecomodder.com/forum/attachmen...1&d=1382342541 |
Congrats!
We had a member here with a 1st generation Honda Insight whose goal was "70 MPG at 70 MPH". I don't think he quite got there, and then ended up selling the car. |
Thanks. By intrapolating my steady speed fuel consumption figures, I must be around 67 mpg at 67 mph and 70@70 is just what I can expect with my future aeromods (and maybe even longer gearing).

Very nice work.

Great gas mileage you are seeing at those hwy speeds, I am curious as to what improvements in mileage could be had by driving at 100kmh compared to your 130kmh run.

Great job!
Just curious, what type of pavement on your test run. Concrete or asphalt? Was any Ethanol mix in your fill up? |

72 mpg @ 100k is really good!
that's about what my car gets on the hwy (73mpg in imperial gallons) it is a 90hp tdi. The new New Beetle is 200hp , don't figure. |
You guys should take your scangauge and go to Germany for a week and do some real high speed driving
