The problem with using dragstrip numbers is that they don't account for wind resistance, air density, temperature, humidity, etc.
Actually I posted the simplified explanation. The program I used DOES account for Altitude, Humidity, Temperature, Drag Coefficient, etc. I guessed at the drivetrain loss. The 284 WHP was calculated with 20% Drivetrain Loss. The 298 WHP was calculated with 17% Drivetrain loss. If the actual drivetrain loss is MORE than 20%, then the Mercedes Engineers need to be shot...
