Additional Notes

  • The hydraulic brake/clutch system capacity across all four configurations listed for the Porsche 911, 991 (USA) is 0.45 liter, which represents a service fill volume rather than an overhaul figure, reflecting the relatively small reservoir size typical of modern brake fluid systems.
  • A 24-month change interval applies under normal use conditions to every configuration in the specifications, meaning brake fluid replacement is time-based rather than mileage-based for all listed variants.
  • The 911 Carrera 4 / Targa 4 and the 911 Carrera 4 GTS / Targa 4 GTS both carry an additional daily check requirement alongside the 24-month change interval, a detail absent from the two 911 Carrera 4S / Targa 4S entries.
  • The 911 Carrera 4S / Targa 4S appears in two distinct power output variants within the specifications: one rated at 294 kW covering 2012-2016, and another rated at 316 kW covering 2013-2015, both sharing the same 0.45-liter capacity and 24-month change interval.
  • The note "hydraulic brake/clutch system" is consistent across all four rows, indicating the 0.45-liter capacity figure applies to a shared fluid circuit serving both braking and clutch actuation functions in these configurations.
  • The 911 Carrera 4 GTS / Targa 4 GTS has the narrowest model year span in the specifications, covering only 2015-2016, while the 911 Carrera 4S / Targa 4S at 294 kW has the widest span at 2012-2016.
