So where does the performance Model S sit with regards to the world's fastest stock production sedans? (By fastest I of course mean 0-60 times, not top speed). From what I can see in various online articles, the Model S seems to be around #5-10. Cadillac CTS-V is the fastest @3.9s, I believe. BMW M5 @4.1s Mercedes CLS63 AMG @4.3s What else beats 4.4s?
