The top fuel cars still used Hemi-based (the real hemi) engines with dual plugs for each cylinder and twin ignition systems.
Now, for all you nay sayers: For one, if you're only holding on to your car because you can't get any money for it, it sucks to be you! I don't think anyone on here has said that the Xfire is one of the greatest cars on the road. All cars, and I don't care how much they cost or how much praise they get, have problems or imperfections. Hmmm, let's see, BMW = Idrive, Porsche = crappy interiors (getting better though) and cooling problems, Ferrari = electronic shift issues, G35s = Oil burning engines, etc.
I've been defending the Xfire against ignorant comments pertaining to the fact that it isn't a true sports car, that many cars are far superior, bla, bla, bla.
You all need to stop bit*hin'! You have a perfectly good German built, hand assembled (SRT) sports car sitting in your garage and many of you paid less than what an Accord would have cost you. If you would rather have a boring **** Mazda, or think that a 350Z is so much better, well, go buy one and hang out at those forums! Also, for those of you who complain about maintenance costs, as Mike Rowe would say, "Get Dirty!" Open the hood and change your own oil, get some tools and change your own plugs! It's not difficult. If you're afraid of getting some dirt under your nails, go spend the money you saved by doing your own maintenance on a manicure.
I for one am happy with my SRT. It will blow the doors off of most anything on the street, it gets looks like it is some kind of exotic, and it feels more solid than my G35 Coupe did. Oh, yeah, the G35. Great car except I was told my engine would need to be replaced at 10k due to a model-wide "issue" with the engines. That thing burned a quart of oil for every 600 miles!! I ordered that thing brand new from Japan and waited over 3 months for it. P.O.S.!
