I am working on a bit of an experiment where I stick with M mode (CVT) and 5th gear through ~10 mile section of rolling hills on my daily commute. This prevents the engine braking from kicking in and allows the car to slow a bit when going up hills. I have the car on cruise control between 46 and 51 for the whole section. I tried doing sections of this in 6, however the car keeps kicking down to 5 for a lot of the hills so I am just going to leave it in 5 to make it simple.
My drive is highly reproducible (almost zero traffic) so hopefully the next fill up will yield some results.

Why not leave it in 6th with cruise control?

I have found that when I am going ~48 MPH, the car is in the 6th gear range. At that time you can flip it over into manual mode and it will stay in 6th gear, provided your speed doesn't drop below 40 MPH. That being said, you can drive up small hills with more throttle and not have the car downshift. You can see the ECO gauge not take a big hit with this method of driving. The only caveat is that you won't accelerate up inclines very fast, in fact if the hill is steep enough it will slow down despite you flooring it in 6th gear.

Huh?! My CVT will stay in 6th until MPH drops below 43. It will NOT downshift on it's own even at WOT when in manual mode. |

I've notices *worse* mileage in manual mode w/CVT, because I use more throttle to accel, even though RPM's are lower. In auto mode, the engine revs so high at small throttle that I back off the throttle and don't get much accel.

Doesn't take an engineer to figure this one out, bud.

Hey, basement genius...
People have been discussing the possibility of manumode being more efficient for the last year. If you actually had a CVT, and an inquiring mind, you'd know that the CVT revs the engine very high under mild accel. Leading to the very understandable assumption that keeping revs down by nearly half would be at least somewhat more efficient. The reality is that it doesn't. But I guess it would take a (real) engineer to understand that. |

It is imperative that you guys keep speeds to a max of 70mph if you're looking for economy. The difference in fuel economy between 70 and 80mph can be as much as 6-8mpg on some cars. |

Heck, it's imperative that you keep the speeds between 55-60 if you want the best mileage.

Not necessarily true. Many cars have multimodal graphs for speed vs. mpg. Depending on the car, you could be getting better fuel economy at 65mph than you would at 50mph depending on engine and gearing. |

So if you want to see your car downshift itself, set the cruise control at 45 MPH, gear 6, and find a hill. Last edited by ocellaris; 10-08-2012 at 08:44 AM. |

It's kinda sad how the car can't climb a moderate hill in 6th. I feel like the little engine that could as the car slowly starts to loose MPHs.

For CO, it's probably a slight incline!
