Yes a gearing change would lower MPGs for those cars equipped with it, and I guess would lower the overall average MPG of all cars if they are somehow keeping track of how many are sold with higher gearing versus those with lower.

BUT they can still advertise the 29 MPG highway as they are now, just as ford advertises 31 for the mustang. We all know you can only get that with the higher geared mustang, but general public won't realize it. I'm not saying lower the gearing and thats it, but instead give us another option just like ford does.

But again, as I said before, I'm sure offering a gearing change could cost GM more money in development and assembly and such rather than doing something simple like writing a new tune or adding intake/exhaust tweaks.

But who knows, if all they are going to do is offer a revised tune then I guess that is probably a cheaper way to go.
Because shorter gearing does not give your car any more power. It just kills your fuel economy.

A car that has 430HP will have 430HP whether you have 3.42's or 5.13's. Meaning it will not accelerate any harder with the shorter gears.

All shorter gears do is help you get off the line harder and into the powerband. Thats how it improves ET's. Once the car is in the powerband though, it will not be any faster. That would be physically impossible.

So unless you launch your car on slicks at every stoplight, shorter gears would be nothing but a downgrade.

1. How much weight would be saved going from the 6.2L to the new 5.5L (aluminum block right?) from just switching out engines?
Absolutely nothing.

They are both all aluminum engines, the small amount of extra material on the cylinder walls probably adds up to about 5 ounces of total weight difference. The architecture if the engines is the same.

No, like Ford, the gear ratios would be completely optional. That way, there is no effect on the fleet mpg or gas guzzler.

I would wait to see the new interior and performance. The 2012 will be out by the end of next year most likely... so waiting a couple months might be worth it.

all they have to do is raise the rev limiter a little and there's your "increase" in power. A redesigned air box can result in 10-15 hp more. What i'm getting at is it won't take a lot and don't expect another 75 hp for those that are speculating and getting their hopes up.

I wouldn't expect anything drastic like new redesigned cylinder heads or cam or something lol.

small simple changes .

In the end, who cares, it's not like you're gonna keep your car stock anyway..

Why dont they just make the dam car lighter. The power is already there it just needs less weight.

Because that would be VERY expensive to do on this platform. Adding power would be much easier and cheaper. Keep in mind they are moving to the lighter, smaller alpha platform for 2014 so to do a major overhaul on this one (when it's selling very well) would be a waste.

Also raiding the performance parts bin wont cut it. Everything would need to be certified and go through the government and EPA testing. There's a reason why most of the parts say "off road use only".

Your last statement is not true. Shorter gears will cause your car to accelerate faster until it reaches its top speed. They work from a stop or from a roll. Its not more HP, its mechanical advantage.

Yes I know what shorter gearing does. Of course it does not add any engine power. Just better transfer of torque. But I don't see any other reason for a power upgrade other than getting better 0 - 60 times and better quarter mile times right?

So the correct gear ratio will also accomplish that.

If your saying lower gears are not better for performance, why is everyone wanting 3.73s and 4.10s? I know that going lower and lower for gearing doesn't necessarily mean faster, but if thought out correctly, it would help times. For instance, 3.55s on the V6 would equate to 3rd gear toping out right at or above 100 MPH. That means no need for a shift into 4th, and lower gearing = better 1/4 mile times on a stock car.

And I still stick with the idea that GM can still advertise the same MPG ratings. (with its standard gear ratio)

Maybe I am missing something but is there even a first major change? Unless it's the Z/28.

Changing the gearing essentially only changes on either having quicker acceleration or higher top end. But I would say that the Mustangs do have better gearing for overall street performance.

Hood is aluminum. You're not going to shave any weight there.
Trunk could do with a pound or two less.
