The 6.4L Hemi isn't just for this limited edition. This is basically what the new SRT-8 will be like, except for the dress up paint and interior, so the R&D isn't just for a limited run car. As for the time, yes last week at Sears Point one ran a 12.44 @ 100 mph. Yes it is only one run, but being almost a second faster than a 2008-2010 SRT-8 (in similar conditions runs close to a 13.3) shows that the 2011 SRT-8 is one heck of a beast. Also should be noted that the car that made the 12.44 run was an autostick car, with stock Goodyear tires on it.
