Assetto Corsa Competizione – GT4 Pack DLC & Update V1.5 Released

Kunos Simulazioni released the GT4 Pack DLC for Assetto Corsa Competizione on Windows PC via Steam for €19.99. The Xbox One and Playstation 4 console versions will become available in the fall of 2020.

Together with the GT4 Pack DLC, Kunos Simulazioni also deployed Update V1.5 for Assetto Corsa Competizione, including a healthy list of new features, fixes, and improvements. Check out the full changelog below for more info.

The GT4 Pack DLC for Assetto Corsa Competizione brings you 11 new cars from the official GT4 European Series from SRO Motorsports Group.

The GT4 class is an amazing racing category, and although most of the time it is dedicated to amateur drivers, it often acts as a starting point for a driver’s career in a GT racing environment. These vehicles are incredibly exciting to drive due to the equalization of performance across the board. Driver skills are key to succeeding.


The DLC includes the following cars and relative liveries:

  • Alpine A110 GT4 –  (7 new liveries)
  • Aston Martin Vantage GT4 –  (7 new liveries)
  • Audi R8 LMS GT4 –  (4 new liveries)
  • BMW M4 GT4 –  (8 new liveries)
  • Chevrolet Camaro –  GT4R (2 new liveries)
  • Ginetta G55 GT4 –  (1 new livery)
  • KTM X-Bow GT4 –  (3 new liveries)
  • Maserati MC GT4 –  (1 new livery)
  • Mclaren 570S GT4 –  (5 new liveries)
  • Mercedes AMG GT4 –  (10 new liveries)
  • Porsche 718 Cayman GT4 Clubsport –  (4 new liveries)


The GT4 vehicle category will be fully integrated into Assetto Corsa Competizione for the DLC owners:

  • Championship Mode: GT4 Season available
  • Multiplayer: the relative game update allows players to assign their vehicle to default category slots. So it will be possible to have a preferred vehicle for GT3 only races, one for the mixed class racing, one for GT4 racing, one for Cup, and one for SuperTrofeo. This allows everyone to have their preferred racing car and livery selected prior to Quick Join matchmaking and entering Competition Servers.


The PC version of the game is available via Steam for €39,99. The Intercontinental GT Pack DLC for Assetto Corsa Competizione is available via Steam for €14,99 ( $14.99 – £12.49).
