You didn't think SRT was going to be left as an after thought at the Concours d'Elegance, did you? The performance brand will be showing its new 2013 Viper GTS Launch Edition in the same striking blue with racing stripes that the car wore in its coupe launches in '96 and '06. It'll have the same 8.4-L 640hp V10 producing that produces 600 lb-ft of torque. The company hasn't released what number this limited run will reach.
