Yesterday I drove my C5 to work and realized just how nice it was to have a tall 6th gear. Cruising down the highway at 70 MPH is a mere 1500 RPM. In the -V, it's somewhere around 2300. While I can't blame the short gearing for my appalling fuel economy in the -V (12.7 MPG), I can't help but think that it would improve the situation.... The car has more than enough power to handle a more leisurely RPM during freeway cruising, don't you think?

Anybody else wishing they would have made 6th gear a little taller?

It was taller in the V1, too. At least it's not turning 3000rpm...

 

[Easy2speed]

I agree. I think 80mph at 2000rpms would be ideal.

 

[neuronbob]

Totally agree, would love to see 2k rpms at 80 mph.

Are you guys talking about the manual or the auto?

 

[Umrswimr]

Mine is a manual.

 

[SlvrBullIT]

my auto is at 2.1K at 75-80ish

 

[gonfishin]

Mine is around 2100 @ 80mph in touring mode.
The mpg at that speed is 27

So are thy putting the .57 gear in the CTS-V? the only option would be the .50 gear which GM hardly uses anymore.

Did the top of your head just throw a tomato at me???

[gonfishin]

Yep! LOL

I'm about there as well, 2100-2200 in my automatic.

I WISH I was getting 27 mpg at that speed, though.

 

[SlvrBullIT]

2k @ 76

yep would be nice i dont need to pass in 6th gear. i had a similiar gripe about my v8 s4 it was really high rpm in 80 on the interstate also (which most of my driving is done at)

Just got back from a round trip - Pittsburgh to Hilton Head and back 2010 CTS-V Auto... I averaged 60 miles per hour each way with an average of 20.4 miles per gallon...Not bad but agree that a taller 6th gear would be the icing on the cake..

Last year I drove my 2007 corvette on the same loop and averaged about the same 60 + miles per hour...but the average miles per gallon was over 29..

The difference was the 6th gear...

Used a lot of auto speed control.. it makes a difference on both cars.

By the way I did not purchased either car for their mileage. The 2007 Vet has been replaced with a 2009 with shorter gearing

Just my two cents

 

[Vetman]

is one able to swap the trans for one with taller 6th gear. Like maybe a .5 overdrive? As my 1990 corvette Zr-1 corvette has. 1400 rpm at 60 mph.
