Re: Help With Finding Top Speed / 2008 ecotec 4 cylinder
Casper, your LTZ V6 is limited to 117. The manufacturer restricts the car to the speed rating of the tires, otherwise there is risk of blowout. You may have seen what appears to be ~119 on the speedo, but at those speeds it's not super accurate. If you'd continued trying to accelerate, it would have cut power.
