1: There are plans to release a spin-off for the Chinese market.
Today, China is a huge market. But they are also a country governed by strict rules that differ from those of the West.
MS wants to get money from them, but it will probably be difficult to release FH5 in China as it is.
Therefore, they are probably planning to release a China-specific FH spin-off to fit the Chinese censorship.
Models like the NIO EP9 and the Wuling Hongguang S could be made for that purpose.
2: For Wuling marketing?
Not surprisingly, Forza has had several free DLCs in the past that served as marketing for car manufacturers.
And in recent years, Chinese car brands have been looking to market their cars more aggressively outside of China.
Using a popular game called Forza Horizon to promote their cars to a large number of players outside of China is certainly a smart idea.
3: Collaboration with Top Gear and other TV shows?
Let's take a look back at Forza in the past, when Suzuki Liana, Kia Cee'd, Vauxhall Astra TGE and some other unusual cars joined the game for a collaboration with Top Gear.
We haven't seen any collaboration with them in FH5 yet, but perhaps a future free update or expansion will bring back their partnership and Hongguang was chosen as the car to be included in it.
However, from what I've seen on Imcdb, this car has yet to appear in Top Gear...
4: Expansion 1 is set in China.
It is most unlikely, but just in case.
The community has always wanted Japan as a location for FH. However, the elements that the community is looking for in Japan, a map that includes a large city and a mountain pass...would be difficult to achieve with the Xbox One specs.
However, small, independent maps like expansions may be a possibility.
And like Blizzard Mountain, Storm Island, Hot Wheels, and Lego, many of the past expansions also served as tests for features to be added to future Horizons.
We already know from the nvidia leak that the expansion 1 codename is "Nightlights".
From this name, many players are expecting an expansion that includes cities, maybe this expansion is mainly cities inspired by regions like Hong Kong and Shanghai as a test to implement a map that includes large cities in FH6.
