Premium is a classification of cars from Gran Turismo 5 to denote the level to which it has been designed, and how damage will be processed. In Gran Turismo 6, Premium cars were known as Detailed (with the exception of cars such as the Nissan GT-R Proto '05, which have no interior; and select Vision Gran Turismo cars, which were classified as Simple). Unlike Standard/Simple cars, they can be viewed in the gallery.

The key characteristic of a Premium car is that it can be bought in the New Car Dealership like in real life, and is therefore always available for purchase. In contrast, Standard Cars are rarer because the player must wait for them to appear.

Most of these Premium Cars are the cars that made their debut in the game (e.g. the Peugeot 307 CC Premium AVN '04 and Chevrolet Camaro SS '10), while some others are returning cars from the previous games which have been upgraded to Premium status (e.g. the Mitsubishi Lancer Evolution IV GSR '96, debuting in the original Gran Turismo; and Shelby Cobra 427 '66, debuting in Gran Turismo 2).

Features of a Premium/Detailed car include:

  • Full interior recreation
  • Physics damage (affects car performance)
  • Scratches, dents, dirt accumulation (minor damage)
  • Deformation and separation of body panels (serious damage)
  • Vehicular roll over
  • Headlights: High/low beams
  • Reverse Lights
  • Windshield Wipers
  • Adaptive Tessellation (GT6)

There are 243 Premium Cars in Gran Turismo 5.
