Putting a PIN on your Charger or Challenger limits anyone else to idle speed.
Autoblog points out the Security Mode update that the carmaker will soon make available to owners of 2015 or newer Charger and Challenger models equipped with large HEMI V-8 engines. It’s adding two-factor authentication, only instead of sending a push notification to your phone or generating a code, it’s a simple four-digit PIN. Combining something you know with something you have (your car key) is required to make the car unlock its full potential. With the security feature turned on, unless you input the code the engine won’t rev beyond idle speed (675 RPM) where it only has about 2.8 HP and 22 pound-feet of torque.
