P&G

[funkeywoookey]

My fellow gas-saving penny-pinchers, I've recently opened my world to the realm of hypermilling and the concept of P&G truly intrigues me. I've done many searches on a few forums and haven't come up with some straight answers to a few of my questions. Don't get me wrong, I've gotten answers, but they were rarely consistent between communities. I hope the expertise of this community will be of most help.

First, let me start off by saying I own a 2007 Hyundai Tiburon. It's a V6 automatic, and it's naturally aspirated (no mods). According to the EPA it can get an estimated 19/27 MPG. On a weekly basis, I have about 80-90% city driving. In my old car I got 29-31 MPG in a car that was only rated 28 on the highway. My goal is to do the same with this Tiburon. To be specific, my goal is 28 MPG average!

EOC does not thrill me, in fact it scares the bejesus out of me. xP
I wouldn't mind, however, to attempt to do a neutral coast. I actually did it today by accident. I was gliding down a hill with a red light at the bottom that I was almost guaranteed to have to stop at. When I got there, the lights immediately turned green and I had little choice.

And now, the holy grail of all my questions. The question that begs all other questions:
While switching into the pulse phase, are there any repercussions from putting an automatic transmission into D while the car is moving?

Is it necessary to "rev match" or rev the engine at all before transitioning back into the pulse phase?

If the need were to arise, would it be okay to rev the engine before putting it into drive in order to make an evasive maneuver?

In reference to cooling of the engine and tranny, are there any major problems with this while coasting? I use the Torque app on my phone to see real-time data, but my car does not support a tranny oil sensor, so monitoring this is almost completely out of the question.


I know these are a lot of questions, but I have a feeling that you will be the most-knowledgeable about this subject. Thank you for your help towards this topic.
