Carolina Turnpike and Road Rally don't have the same cars.
Carolina Turnpike's cars were gasoline powerd and were built by Arrow Dynamics. The new ones of Road Rally were manufactured by Chance/Morgan(I think) and are electric.
Dollywood also has the Chance/Morgan electric cars(<a href='http://www.coastertown.com/Tennessee/Dollywood/Jukebox_Dollywood/Car01.jpg' target='_blank'>Rockin' Roadway</a>), though theirs are much better maintained(ALL of the horns & headlights work) and have radios that play 50s music.
Also, CT had a different layout that RR, it was longer.
