Dodge 2024 Challenger Rt 0-60 Time

Dodge 2024 Challenger Rt 0-60 Time. They seem accurate except for the 3.6. Is there an actual manufacturer claim at all or is it all.

My best 100% stock 0 ~ 60 time was 5.6 seconds, but that was the best of the best it was not a consistent time depending on road surface it could have been as bad as 6.0. They seem accurate except for the 3.6.
