On a recent road trip 1400km with a new SX6 we got 7.8/100 against a stock XR6T 10/100. overall we thought the SX6 was a great car good build quality . The SX6 pulled 1/2 car on the T for 1st 60ft from lights untill boost powered on. Prob due to 6sp agaist 4 sp auto's.And held it's own also in the overtaking lanes as well.
