^^ Exactly, if I'm not mistaken, the most efficient gas mileage is when you are driving 80-90 km/h.
Sad :( |
It'll be different for every vehicle depending on gear ratios, aerodynamics, and a couple other factors. But I think you're in the right area. |

Apparently so, I've been looking around the web. Mileage increases as you increase up to 90Kph and decreases from that point on... unless that's some sort of propaganda so we don't speed ;) I figured the faster you drive, the cost to fuel is less than the gain in speed. But considering drag increases with higher speeds it makes sense. |
Ahh you beat me to it. :p |

gas mileage is not related to speed, but RPMs.
the reason you burn less gas over 90kmph is that your RPMs are typically lower because you're rarely accelerating at a high rate, or racing to shift to the next gear. |

That's only right if you're driving through a vacuum. |

You're mistaken. :p
Higher speed = higher RPM and more drag on your vehicle. Therefore more gas is being burned. |
I was just about to say that. The only reason I know this is b/c Cale's car gets terrible fuel economy if he goes anything over 120km/hr
Sorry to hear about your car though Scott |

Well this is a pretty sweet SUV, and I hate SUVs.

^^Trialblazer SS FTW.
As for SUVs I believe they serve a purpose. Unfortunatly that purpose is not driving around city streets like 99% of SUV owners do.
My parents actually utilize our Pathfinder by going up north in the dead of the winter. You try that in a 2 wheel drive vehicle. |

Also, tell me your RPM at 90. Now tell me your RPM at 100. Which is higher?
I Thought so. |

Funny. I've noticed I am passing a lot more SUVs on the highway lately. (Not that I'm going excessively fast). :p |
