This is because power required to turn a auto at that rpm is more than to turn the manual. This is why autos are rated at between 20 to 22% drivetrain losses and manuals at between 15 to 18%. It is important to note though that anything with overdrive gears will cosume more power in that gear than it would if it was direct drive or 1 to 1. As far as using gas when let off the throttle. Most fuel injected engines will cut off fuel if you let off the throttle and leave it in that gear to decelerate. This is because there is almost no air being pulled into the cylinder because the thottle plate is closed, and it wouldnt do that cats any good to see that much unburned fuel it would hurt emmisions. There is still a small amount of gas but only as small as the amount of air that can be pulled through closed throttle plates or the IAC.

even if the throttle is closed, air is still getting through it
he is saying NO gas is being consumed.
I am saying gas is being consumed.
how are we both right?

fuel pressure has little to do with it in a propperly tuned vehicle-
you also have to concider that at more rpms, less air is getting into the cyliders (double rpms and the time the valve is open is cut in half) there are other little things that come into play as well that I am just getting a grasp on.
according to your thoery, at cruise- gas milage should double from 4th gear to 6th gear. Id say gas milage increases 25% at best.
gas milage is not directly perportional to rpm

I said the computer opens the TB, the throttle cable opens the TB...you guys know what I meant...I'm trying to order computer parts, post on here, and talk to four people about computer problems...

now like wise, when an a4 is interstating, you only have to give enough gas to maintain speed, same is the case with the M6. therefore there is very little difference. this is the point i'm trying to make. if you give more gas you accelerate.
very simply gas = energy, air is free
I think you all are really dense, I've got an engineering degree, i have some clue of how machines work.

this guy is running on no fuel
wow, the LS1 really is more advanced that the LT1
well, i have some more support for the LSx side next time they bring up the LT1 vs LS1 debate
Must be the opti...
(with that said, my truck has individual coil packs, i wonder if i can hop on this massless perpultion idea
)

omg, this thread had me cracking my *** up with that moron whobetterwhatever's gas mileage explanations! !!!!
if your engine wasn't getting any gas when you took your foot off the pedal, it'd die you ****in retard. im not even gonna get technical on this discussion as your intelligence obviously wouldn't understand it... so I'll leave it at that. go play with your lego's.

I dont see how he is denying the gas milage factor. Yes if driven the same way manuals get better gas milage than autos. Though most autos probably get better gas milage than my m6 because of my heavy foot but that is beside the point. argueing about speed is also pointless. Both can be made just as fast as the other, just manuals require a good driver to acheive good times where in an auto you just gotta launch and its over from there. As far as stock, manuals with a good driver are usually faster, sure you can add a converter but the manual can use that same money for other mods to acheive the same times. My point is neither are superior than the other and its personal prefrence.

I go on vacation for 4 days and my post got blown out of proportion!For the most part, I have come to the conclusion that it is all going to come down to driving and test driving a SS with the M6.
I realized today the pleasure of not having to wright out a car payment cuz it is the 20th so I am going to enjoy that for a little longer and put some serious miles on my V6 cuz we all know that even though it is showroom condition it is worth squat
thanks for all who replyed, the main question was mainly what will hold up for the long run, especialy since I will rarely be in 6th gear and the hole traffic situitation, but in the end it will only be solved by me driving and seeing what I feel.

hey, atleast I don't spend thousands of dollars in mods on a car that will be worthless 5 years like most of you *** clowns , but I undrstand why you all do it, It's simply t make up for the holes and unfufilled goals in your lives. yeah, you all can't succeed at anything that takes intelligence or skill to accomplsh so you try to shield you patheticness from others by driving a cool car but your nothing but an average everday person, with average jobs and average boring lives.
Why would anyone get exicted about a different color of gauges or if your car is 1/2 sec faster, or if you have 11" tires, or i you have chrome accents under the hood, whocares? I sure don't
but you all will never admit,
It was time to say it and you all know it's true.
