If there is enough of a down hill grade that speed is increasing, I'll down shift and use engine braking, no fuel used and brakes aren't going to possibly overheat...

The thought of wearing out engine by downshifting is basically B-S...

As an engineer myself, I'm very very interested in how you've come to these views...

If in a manual, running down a hill, the engine is turning at the same speed as if you were going up the hill...how can that be damaging, or a design flaw if the CVT behaves the same ?

[quote=gr8gatzby]You got a ticket for speeding, or for coasting in neutral? How would a cop know if a vehicle is in neutral in either transmission?[/quote

For coasting in neutral. I don't know how he knew, but he was right. I was from out of state and didn't want any problems so I didn't argue.

My 2011 Avalon will keep the same engine speed if I'm on the highway doing 75mph and let go of the gas pedal to coast for a bit when going downhill.

It would cause extra wear and tear if it disengages the gear every time to took your foot off the gas pedal for the slightest amount and reapplied.

The MPG gauge shows 99.9mpg when coasting in gear.

OP, you need to get a scan gauge and re-evaluate your driving style because it's FLAWED.
