That is because most companies are doing dyno runs with the AWD fuse pulled and run RWD only.
Tork also runs Stingers with the AWD fuse pulled on their dyno.
This is one of old dyno results we had, when we ran all four wheels on the dyno.
This AWD baseline put down 292ps(288WHP) and 47.59kgm(344ft-lbs of torque), while RWD models make ~320-340 WHP.
AWD had about ~10% extra drivetrain loss than the RWD Stingers.
