2015 Subaru Outback Limited 2.5 Carbide Gray
Has anyone done a comparison on gas milelage using just the paddle shifter vs just normal driving with the automatic transmision?
And you are going to give us some sort of data other than your opinion I hope, to make that claim for all driving circumstances! Or is this just a hypotheses, otherwise known as a WAG, (hopefully no other colloquial definition is required). ha haPaddle Shifter results in higher RPM's which in turn burn more fuel.
It has been posted this is not recommended on a regular basis and is only ment for maintaining speed on a grade.I use the paddles mainly for downshifting, as when approaching a red light or corner.
Having said that most engineers don't like being in the car with me either.Subaru got back to me via email from my question through the website;
Thanks for your patience as I researched engine braking in your 2013 Outback with CVT. I sent it to two separate Technical representatives. They both replied with similar feedback.
It is only recommended in situations where the engine braking would be needed, such as “when descending a grade." Normally, a driver would have no need to engine brake when just coming to a stop at a light or stop sign. Since the transmission is not designed to handle this, it would accelerate wear on the CVT.
I think that's enough for me to not make a habit of it. Thanks for all the input - good forum!
I guess I'm having a hard time accepting this from a couple of "tech reps" not the engineers or test group that came up with the design. Why have paddle shifters for up/down shift if it's not to be used whenever you choose. That's the whole point of having them! Otherwise they would just stick with D, 4, 3, 2,L. We used the "tiptronic" shift able transmissions in both an Audi and VW Passat and never had a problem. I may be completely wrong, but I think some naysayer's are stuck in the past design mindset of older generation transmissions. BTW: Every time I start and drive the darn thing I increase wear.It has been posted this is not recommended on a regular basis and is only ment for maintaining speed on a grade.

Yea as a kid I had to write "I will not question the teacher in class", oh I don't know hundreds of times before getting my own personal study location in the hall. Also voted "most likely to piss off others by questioning questionable statements"!TECHNICAL FOUL! -- Unsportsmanlike use of logic on the intertubes!
...maybe there should only be an upshift paddle?
Agree.I find the paddle shifters pretty much useless in this car.
That is true of many stick shift drivers. They will wind it up before shifting, whereas the auto(computer) will shift at the most economical point. As I mentioned somewhere else , the multi-gear auto trans "hunt" constantly to maximize economy. Drives me crazy (not a long drive, I admit) going up to Auburn from Sacramento.My wife lets me drive her fancy six speed stick/auto car and I did an experiment when she was out of town for a week and drove the stick vs. automatic shifts for two days each and the mileage display on the dash showed it got much better mileage when I let the trans decide when to shift. The auto trans mode kept the little "Eco" light on nearly all the time, while my winding it out before shifting didn't. Not a scientific test, but proof to me that my driving style causes the mileage to suffer when I'm using manual mode.
Correct-oh, when you're off the gas you're basically getting infinite miles to the gallon. I believe the post you're referring to was aimed towards accelerating; using the paddle shifters will likely result in up-shifting at higher RPM's than with CVT-auto.Does any one have a source saying we shouldn't downshift to engine brake? To the person that said the engine revs higher and uses more gas, I think this is not true. The engine is rotating, but modern engines are smart enough to cut fuel supply during engine braking. The mpg gauge on my OB seems to peg to the + (fuel saving) position during engine braking.
Using 6 prefixed gear ratios via the paddle shifters or a very wide range of possible gear ratios available to the CVT in AT Mode? Umm No simply from the point of the CVT having a much wider range of possible gear ratios to use it makes zero sense that paddle shifter use would return better mileage over a fairly large period of time and conditions.Has anyone done a comparison on gas milelage using just the paddle shifter vs just normal driving with the automatic transmision?
