I was looking for the gear ratios of the 6 speed manual in the 2011 Forte Koup EX.

The reason I ask is because I find there is very little difference between 5 and 6 gear in my car (about 200 RPM, running around 300RPM at 100 km/h in 6th.). I find it weird 5 and 6 would have such a small difference in ratios episcally since 6 gear is supposedly for highway cruising.

Once you register go to "service Info" and hit the drop down. click on Forte, click on your year and engine...then click on manual transaxle, information, specs, and all the data on ratios will appear...LoL!

Like this (but looks better on the Kia site...LoL!):
Engine type
Gasoline 2.4
Manual transaxle type
M6GF2
Gear ratio
1st
3.267
2nd
1.931
3rd
1.696
4th
1.276
5th
0.027
6th
0.829
Reverse
3.588
Final gear ratio
4.063(1,2,R)/ 2.955(3~6)
T/M oil capacity※
1.75ℓ (1.85 US qt, 1.54 lmp qt

FYI: 2010 and 2011 show same gear ratios.

I think your missing a 1 in your 5th gear.

Negative...the specs above were copied and pasted from the Kia site..."I" didn't miss it -- you'll have to bring that up with them...LoL! I think you're right...should read 1.027:1.

Even the 5-speed auto has no 1.00:1 ratio...4th and 5th gears are both overdrives.

after the diff is factored in there isn't a real overdrive gear in the forte 5 spd, comes out to still a little more than 1:1 in 5th

took my friend who owns a 90 240sx with stock ka24 single cam, exhaust and intake, and also an 03.5 mazdaspeed protege (prob slowest stock turbo car in a straight line ever but still quicker than our car by a good bit) and he was surprised at how quick the forte was in 2nd and 3rd, I ran through 2nd and a bit of 3rd going to wendys and he was like "damn this cars a lot quicker than you'd think! it would blow the doors off the 240 for sure" lol
we pulled back onto one of the back roads back to school and i punched it and he was like "damn your car is torquey!"
lol
thats a compliment from someone who drives an msp everyday, they may lack power but they have pretty ridiculous torque for what they are lol, something like 188hp 200 tq

Please explain your rational... the auto tranny's 5th gear ratio of 0.713 IS an overdrive gear -- the tranny output shaft is turning slower than the engine speed in 5th gear -- that's the definition of overdrive. You don't "factor" in the differential gears to determine overdrive.

The final ratio of the autotranny in 5th gear is 2.209:1 (0.713 X 3.099) - 3.099 is the differential ratio.
The final ratio of the manual tranny in 6th gear is 2.449:1 (0.829 X 2.955)
This helps explain why the auto tranny is similar in gas mileage compared to the manual tranny.

The 2011 6 spd auto tranny final drive ratio is 2.227:1 (0.772 X 2.885)...and the 5th gear ratio is 1.00:1, neither the 5 spd auto or 6 spd manual show any gears to be 1.00:1

Is there a difference between the 6 speed in the SX and the 6 speed in the EX? How about the differential? I was just curious because I've read the SX is running around 2000 RPM in 6th gear at a 100km/h where as my EX is running around 3000 RPM in 6th gear at 100km/h.

Yes there is a difference -- they don't appear to be the same tranny.

The SX 6 spd has different gearing AND has two differential ratios: 4.063:1 (1,2, R) and 2.955:1 (3, 4, 5, 6).

The EX 6 spd uses one differential ratio (4.333:1)

The EX will indeed cruise at a higher RPM because the final drive ratio in 6th with the SX 6 spd tranny is 2.449:1 (0.829 X 2.955) while the final drive ratio with the EX 6 spd tranny is 2.742 (0.633 X 4.333)...for acceleration I'd prefer the 2.0's 6 speed over the 2.4's!
