I have a '12 SE Hatch with the sports package with the DT. I noticed some huge discrepancies in 0-60 times among testers; with the fastest 0-60 being 7.5 sec, slowest just under 9 seconds with a similarly equipped car? Im pretty sure the 7.5 was achieved in S mode, traction control off and doing the brake on, revs to 4k release the brake step back the gas (to avoid wheel spin) launch. It would be tough to time a start using this technique but may work good for Auto-X when you trip a timer.
The car handles much better with traction control "off" however its not all the way off, but more like a sport mode that allows slightly more wheel spin. My opinion anyway.
I think that the car is faster, even in a streight line with traction control off.
