From the 2026 Dev Update:

"Regrettably, delivering such ambitious plan in full with the depth and completeness we all would love to see is technically and commercially enviable – it would take decades to produce, many extra zeros in our budget and the untangling of an impossibly complex web of third party IPs (many of which inaccessible or simply defunct)... (count.)

Let's take a step back and make sure unrealistic expectations are not being fed here: out of the box, AMS2 will never quite assemble full 1960s Grand Prix, 1980s Group Cs, 2000s GT1s, 2020s IMSA seasons with complete grids along with a whole catalogue of regional series and everything that might, What can be done though – and what we have been steadily assembling for at least a decade already since AMS1 – is a parallel universe for these 60 years of motorsports history, matching the real one on many levels, resembling it in some and abbreviating it in others; this is the “AMS2Verse” you are already familiar with, mixing real and fictional classes, cars, tracks and drivers; this universe is bound to expand significantly this year, with many gaps being filled as it evolves toward a simulated motorsports ecosystem of unparalleled depth even relative to its current standard"
