The 0-60 time I saw for the Demon was 2.3 seconds. The S is 2.5. Again, that was me clicking the first thing that popped up when I googled: Top 10 0-60 cars.

"We reported that Jeep has decided to exclude the Tesla Model X P100D from its list of SUVs in order to lay claim to having the "quickest" production SUV in the world.
Now, Dodge has come forward with the "fastest production car" ever produced. It's the all-new 2018 Dodge Challenger SRT Demon, and they say it can also tackle a zero to 60 sprint in 2.3 seconds.
The National Hot Rod Association (NHRA) banned the Demon due to a lack of safety equipment necessary for its type of performance (it only has one seat and has been substantially stripped down to reduce weight). It's a street-legal drag car, by every definition."
Depending on where you look, or who you talk to, the Demon's 2.3-second zero to 60 sprint may have just succeeded in topping the Model S. According to Tesla's website, the Model S P100D is capable of a 2.5-second time.
However, that information was posted prior to the new Ludicrous Easter Egg updates. If Dodge simply had to beat 2.5, the challenge may have not been so difficult. But published figures for the Tesla Model S P100D with the new Ludicrous upgrade show a 2.28-second time.
Motor Trend did the testing and is sticking by its methods, a similar real world result has since appeared."
Basically, if you strip the model S down for racing like the Demons is stripped down, the Model S is faster.
