wow I had no idea they made a sport auto I thought all g35s were 6mt... O well I like the shift ***** anyways no homo

 

threads like this one make me laugh some times. We all have our own style of driving.

 

This seems to make sense.

 

Yes, you described engine braking perfectly.

But, the question is whether or not engine braking helps during FULL braking.

Like someone else said, the stock brakes are more than capable of locking up the tires. Your braking is thus limited by tire traction, not drag by the brakes (or engine). So, I doubt engine braking at full brakes would help.

And like I said before, if your rpms drop faster during full braking than then engine compression slowing your car down..... having the car in gear would create more drag on the brakes, not less.

 

in my car (05 X) im not sure if its supposed to,but if you hit the brakes hard it actually puts it into neutral. even though the screen says D or a number, if you take your foot off the brake it doesnt move, and you have to step on the gas alil, and it revs like in neutrl then kick into gear.
but yeah i downshift pretty often, usually only from 5-3, maybe 2 if going downhill.

 

I thought this car was designed for Sporty Driving. of Course you can downshift and "drive" the car the way it is really meant to be driven. That's why they incorporated a Manually shifting automatic tranny. The old non-manually shifting Auto trannys were not designed to downshift - that would cause damage. Not this car.

Happy Motoring !!!

 

Just found this thread.


The new Coupes present an interesting twist to this. As the new G37's "rev-match" on the down shift, are you really causing any wear on the transmission syncros? I think that's a good question. In my 05' MT sedan, I only down shift when I'm driving hard. I mean the only real reason for downshifting is to be in the proper gear for the exit of the turn. There is no real reason to do it in day to day driving.

I always went by the old saw; "brake pads are cheaper than a transmission". But with the new rev-match, I see no reason to not do it.

 

exactly,

people that are worried about down shifting and what not need to fix their skirts and just drive the car

 

The way I see it is, I have a left and right paddle. If the downshifting wasn't welcome, I'd have a right hand paddle only.

I hate getting out of my car and into the wife's.
I drive that thing at night and high beam everyone, as my brain tells my left hand to downshift and all I get is the blinker ****!

 

We had a very in-depth discussion of this on my g37.

Rev-matching does NOT save your synchros. It just makes clutch engagement into the selected gear smoother.

Synchros do their work when your shifter goes into gear, not when you engage the clutch.

Double-clutching is what saves synchros, not revmatching.

And please, no fast and the furious references; I'm absolutely serious.

 

I have driven manual transmissions for years. Here is my experience. I downshift constantly, try to optimize my revs on turns and speeds. By downshifting, I have consistently tripled the the life expectancy of brakes compared to an auto transmission. You will NOT wear down your clutch by doing that as long as you don't ride your clutch. I usually exceed the life expectancy of my clutch as well. That is what wears down clutches. When you engine brake, as long as your are not jumping 2 or 3 gears down, you will not put any wear on your clutch since it is fully engaged. This is not true with an auto, because the torque converter does not work that way, you can put extra strain on the torque converter which does not lock like a clutch but slips.

 

Au contraire, mon ami - why not always be in the right gear to drop the hammer, even in day to day driving?

 

Wait... You used to have to double clutch to clear the gear completely before engaging it again. The invention of synchromesh basically made that unnecessary because the gears were synchronized. So double clutching is more to show off then do anything really useful for you car. It also slows down your shifting time.

 

+1, but even for day to day driving, it is safer to be in the right gear at the right time. Do you mean to tell me that you get off the freeway with a 6mt and go all the way to a stop in 6th? That is dangerous in my book. What if idiot comes barreling down the road about to hit you?
