I do, I've driven both of them and auto crossed both of my 06 STI's. At the time the cars were not even in the same race class. I'm not saying the Neon SRT's were dogs by any means, I loved, LOVED driving the SRT Neon and would expect the Dart to be much more capeable. I could only hope and dream that an SRT Dart would have a solid AWD system with 300hp as I could easily be a customer. I would expect a ~250hp FWD Dart.
Ralph knows what an STI is capeable of as he lost to a father and son team at the 2011 Targa Newfoundland Rally while driving a 2010 Dodge Viper ACR. Which as many of us know is an insanely fast car and is still one of the fastest lap times around the Nurburgring for a production car.
