Chevrolet Cobalt Forum : “whats the top speed?”

Yes, I believe it is electronically governed at 110 mph similar to the Saturn Ion, which it shares engine/transmission/basic platform with.

'06 is governed to 104, not sure about '08s

I have an 07 LS coupe, 5 speed.  It gets just past 110 then governor kicks in (speedo reads like 112)

(I am not quite sure about the auto's, but...) I have the SS/SC 5-speed, and I have had it (on more than one occasion) at ~150 mph. The fastest I have had it is 155 mph, with a tail wind. But otherwise it is 151 mph, gov. limited at 5750 rpms.

get a chip then the skys the limit or at least until the motor blows

i have a 2006 cobalt ls, my cutoff was 170 km/h, topped that 5 times... a skyline weaved through me out of nowhere lmao.

not sure but i have gotten an 05 ls up to 105. I must say that it handled pretty well to. it felt really smooth, and it
didnt feel like i was going to die. but if i would have hit anything (pothole, mouse, ant *lol*) i am pretty sure i
would have died. lol

I HAVE A 06 SS COBALT, IVE HAD IT DOIN 220 KM IN FOURTH GEAR BUT STEEERING WAS VERY LOOSE I THINK ITS CAUSE I HAVE AIR DEFUSERS ON THE FRONT CLIP, IM NOT SURE IF THERE IS A CUTOFF AND IF THERE IS I WILL REACH IT SOON ..

My 06 cobalt took me up to 120 I am pretty sure I could have gone faster except I was in a constrution zone.

I have gotten the LS up to 116 after about 2 miles down the thruway lol

I have a 2009 SS Turbo.. Top speed is over 160 miles per hour;)

I dont have a speed limiter, thank you Trifecta tuning! On the dyno with calculations I maxed out at 178 mph. And by calculations they actually add in effects like wind speed and road resistance. 2005 Cobalt SS/SC Stage WTF

Wish we could race sometime.. Where you live?

Yup... same here.  Trifecta tuning FTW!!!
