Wow, just checked out one of the Mustang forums I frequent and saw this:
I got to evaluate a 2015 Mustang today
I guess this guy did what that CarScoop article was talking about when they said current Mustang owners were invited to rate the 2015 Mustang. I've only read the first out of the 6 pages in that thread, but he mentioned a 2.3L Ecoboost making 310bhp and 34mpg, and also an Ecoboost V8.
**** just got real.
