I agree 238BHP is very suspect. In every single comparison test [ never mind stop watchs or HP figures ]. The crossfire out performs the RX8 by a large margin, also the TT by slightly less. I actually suspect the Crossfires 215HP is conservative, it certainly feels like more.
Look at this forum, I think with very few exceptions, we were all a bit worried about the 215HP figure and 0-60 times before we bought the car. Once you actually drive it, all those worries are gone. I think the supercharged version needs to be there but I wouldn't buy it. The Crossfires got all the power you need and want for 99% of the time.
I've said it before, I think the Crossfire is THE perfect Sports Coupe ever.
