After 2 standard Crossfires my third had to be the SRT, and though I new that an extra 115 plus BHP from the AMG lump (or is it true that's its actually 125 more!) was going to make a difference I was amazed at its performance - which can only be described as Shattering. There are not many cars on the road that pin you into the seat when you plant your right foot at 90mph! and the SRT will eat most cars for breakfast off the line. But the ride is harder than the standard and the car is beefed up in many ways to cope with the extra horses. Under normal driving conditions I get 330 to a full tank just same as standard model. Once you've driven the SRT theres no way back!
