The 2020 GT World Challenge Pack for Assetto Corsa Competizione has been released, adding two new cars and Imola to the sim.
Assetto Corsa Competizione adds 2020 World Challenge pack

Given the uncertainties surrounding the 2020 Motorsport season, this latest ‘GT World Challenge Pack’ DLC available to Assetto Corsa Competizione PC players is a great surprise.

With the real-life GT World Challenge Championship affected like so many others, they visited two new tracks not originally on the calendar, Autodromo Internazionale Enzo e Dino Ferrari and Magny-Cours. Unfortunately, restrictions for the developers being able to map Magny-Cours meant it couldn’t be added to the DLC in time, but we do now get to enjoy the addition of Imola.

As well as a new track to learn, the pack now includes the latest Evo race variants from Mercedes-AMG and Ferrari, the Mercedes-AMG GT3 Evo and Ferrari 488 GT3 EVO. Both models carry over significant aero upgrades from their previous variants and include Balance of Performance (BoP) calculation updates along with all 2020 competing cars when playing in the 2020 game mode.

The pack now includes 60+ more liveries from the 2020 season, but an addition which was not expected was the addition of a new tyre model when playing the 2020 game mode. The Pirelli DHE tyres now feature in game. The physics now include better feedback, more traction and reduced overheating.

The new DLC pack is only available on PC for now but is expected on console January 2021. You can download it today from the Steam store for £7.99/$8.99. This follows on from the earlier addition of GT4 cars, with the British GT pack still TBC. Stay tuned to Traxion for more ACC news and updates and let us know your thoughts in the comments.
