Actually it looks like that 10.7 timing to 200km/h might not have been from a stock Hellcat anyway for MANY reasons:
1) This AEC-imported model accelerated from 100-200kph in 6.8s while in Germany, while every single other automatic Hellcat Challenger did 100-200 in 7.4-7.8s.
1.5) Even the Charger variant, which is far more aerodynamic, couldn't do any better than a 7-flat.
2) Even the dragstrip-prepped models in the US, and I hate to break this to you guys but EVEN the Hellcat REDEYE models can't trap 213kph (the trap speed listed in ABSC's 6/2015 comparison).
2.5) The original four-door Charger Hellcat trapped 206kph in 11.7s (prepped surface) and 207kph in 11.9s (unprepped surface) in a joint-venture test with both C/D and ABSC. Neither time accounting for the rollout of course.
3) The 10.7 listed by a German mag is the equivalent to our 10.4 for 0-200kph. NOT in any way possible even for a Redeye with 3.09 gears or a 91-octane Super Stock/Demon on regular tires and an unprepped surface.
3.5) AMuS got a more reasonable 11.2 time from 0-200 and even THAT Hellcat was no longer stock (it used the aftermarket 3.09 gears); it meant 10.9 with the rollout, which is easily achievable on every prepped American dragstrip with a MUCH BETTER 0-100 time than 4.1s.
4) To add, AEC might have been using Hennessey's tooling kits to make it look like the "insane" monster that it totally is. I get the 11.7 quartermile time, and I believe it can do 11.4 on a dragstrip, but at 213? Not just "no way," but a BIG HELL NO to that trap speed. Mk5 Viper, C7 ZR1, Mk2 Ford GT, Huracan LP580-2, and 570S hardly do that trap speed either.
Disclaimer: Don't take my word for it. Take a look at the American V8 cars from the 1960s all the way even up to today that were tested by drag racers (mostly Hot Rod Magazine and Road Test TV; + some YouTubers), with their 'ringer' quartermile results.
Unfortunately there are still some people out there that believe and trust everything a magazine shows to them. Motor Trend lied about the Mk1 Ford GT performance (it didn't trap 131mph in the ¼mile). Car and Driver lied about the Ferrari 458 Italia performance, and Top Gear lied about the Aston Martin DBS Superleggera performance (neither car traps 134-136mph). Car and Driver also lied about the R35 Mk1 Nissan GT-R performance (only Mk3 and newer cars trap 124mph).
