What's new in the 1.3 Update:

This Update is a huge technical and visual makeover for the Hamburg by 4r map, this includes...

  • Reworked Textures for more realism

  • Reworked Track Lights to more realistic / less saturated lighting. Also added lots of new lights and added night glow effect above the city.

  • Added 20+ new animations

  • Added lots of new trees, bushes and some more high quality 3D vegetation

  • Remodeled some objects and track areas (mostly fixed wheel shaking/bumby road)

  • Added more building roof details, new emissive signs

  • some new custom modeled highway details

  • better lod's & performance optimization

and most importantly:

  • map is re-positioned now to fix the shaking car issue once and for all.

Hamburg by 4r is a 1:1 recreation of Hamburg A7 Highway for Assetto Corsa. It is a 2 to 6-lane Highway that features the route from Harburg (Heimfeld) to Quickborn (Bilsen), through the harbour, city and tunnels of Hamburg. The whole track has been made from scratch and already is in very rich detail. Every model and texture has been built very carefully to keep performance and visuals on a high standard. You can already see pretty much all of the landmarks that you would see on the real road including the Köhlbrandbrücke, Elbphilharmonie or HSV Stadium. The track has a ton of animations, lights and lots of vegetation variation using a mix of 2d and 3d trees to meet all demands regarding visuals and performance.

With the new update there is now 5 spawn locations with each 96 Pits (removed unrelevant spawns, added more pits). There is also a spline for server hosters included.

Install:

Drag & Drop to Content Manager (recommended)

or

Unzip & drop unzipped folder into assettocorsa/content/tracks

This project has been in the making for roughly a year now and has been made possible through your support here on patreon, thank you for letting me do what i love! - I hope you love it too :)

Why it's so dark? Other maps, like Shutoko look fine, but this one is very dark, can't see a shit. Why is that?

Hello, I'm really enjoying playing your map mods, but my system is a bit underpowered. Is there a way to remove the 3D trees? They're really slowing the game down; it's dropped from 60 fps to 20 fps.

RRESSTIBLE · November 28, 2025

After deleting the 4r_hh_hq_trees.kn5 and 4r_hh_trees.kn5 files, I managed to remove the trees. I'm back to 60 fps as before and can now play very comfortably in offline mode.

Anyone having issues with the latest CSP update? My car spawns right under the road, I can see the AI cars driving above me.

Almac · November 11, 2025

I'm getting the same bug, but only at the default spawn point. All the others crash the game entirely before getting that far. Did you ever find a solution? Is it CSP causing the problem?

Are we allowed to host this free version 1.3 on our own server etc? But for people to get the 1.3 update, shall we use the link to here or add the update to the install content? Asking 1st beforehand

of course you can host your own servers with the map - please just make sure to link to the map here, instead of reuploading or sharing it otherwise :)

Sean Dockery · September 21, 2025

I would love to join and get the paid version, but unfortunately I cannot get traffic on this. I even downloaded a 2024 Hamburg traffic mod, but still no traffic whatsoever.

Don't know if is something related to the track or to CSP, but if I try to start a race on this track, the game crash and I have this error: Error might have something to do with: AC\game.cpp (112): Game::onIdle AC\game.cpp (210): Game::run AC\acs.cpp (477): wWinMain f:\dd\vctools\crt\crtw32\dllstuff\crtexe.c (618): __tmainCRTStartup
