This late model Porsche 911 Carerra S Cabriolet racing at the Hallett Race Track near Tulsa, Oklahoma, appeared to be completely stock and un-modified. If this is the case, then the Porsche is still a very quick sports car with a 0-60 time in the low 4 seconds and a top speed of 186 mph! Of course that is going to feel even quicker in a convertible Porsche 911 as opposed to a coupe version. I am a bit biased because I love Porches, particularly 911 turbo-charged models, but I think this Porsche looks and sounds awesome especially when accelerating.
