A familly member of mine has an eclipse that I drive on a regular basis, it is an 03 GTS Spyder with the sport-tronic(auto) transmission. There is definatly no contest between the two, the csvt would win! I have never taken the eclipse to the track but I predict that it would be in the low 16's. If it where a hardtop and manuel it might be alot closer, but anything from a roll the csvt would still win. The eclipse has more torque then the tour, plus the GTS version has slightly steeper gearing then the regular GT, so off the line I would look for the eclipse to jump ahead then slowly get reeled in.
