Re: compare xfire performance to other cars, you'll be surprise
I always thought it would have been nice if Chrysler used the 3.5 engine with, what, another 20-40 hp. But I find the n/a engine to be snappy and I've had mine to 140, so it has adequate power and more than enough to get my license revoked. The SRT6 is a beast, and still a bargain compared to sports cars with equivalent performance.
