I do a lot of high way driving and I've come to the conclusion that there's some dark magic happening in the Honda 1.5T engine in my hatchback. Either that or it's a combination of good design, lightness, and aerodynamics.
We all know that the car gets great gas mileage. A few of us also know that aerodynamic drag increases as a square root. So you'd expect gas mileage to drop insanely as speed increases but I've found that it's almost linear, which is crazy.
At 65mph, I get 42 mpg.
Looking at it proportionally, I would get:
55mph = 49.6mpg
75mph = 36.4mpg
85mph = 32.1mpg
95mph = 28.7mpg
105mph = 26mpg
Here's what i've measured, each on the same stretches of thruway in nearly the same conditions at night on stretches of about 10 minutes.
55mph = 51mpg
75mph = 38mpg
85mph = 32mpg
95mph = 27mpg
105mph = 23mpg
It stays insanely and unreasonably linear. When winter really sets in and temperatures are below 30, I expect about about a 15-20% drop (purely due to air density).
Is anyone else seeing this pattern?
