It seems as though the 212kph (132mph) trap speed was highly inflated based on the 0-200 and 100-200 timing results.
Hellcats have very well-engineered motors and efficient supercharging systems, designed to run on race gas (unlike its Ford or GM counterparts which can only run on premium unleaded without mods).
With that being said, even with 100 octane race gas (+70hp over results on 91 octane gas) it'll still have a hard time trapping 132. I reckon 128-129mph at best, and even Hellcat Redeyes and Jailbreaks have a hard time doing even that! ;D
