Introduction Shanghai Tianma Circuit is the first circuit ever constructed in East China area. It currently hosts events including China Touring Car Championship, China Truck Racing Championship, China Endurance Chamipship, and Tianma Endurance Series. It hosted Formula Pilota China and WTCC Race of China in 2011, before these events started to shift to the larger and more advanced Formula 1 Shanghai International Circuit. The track is 2.063km long with 14 tricky corners, providing good challenges to both drivers and race car engineers. Shanghai Tianma Circuit also provides performance driving school, drift school, open track days, as well as a number of other various services, making it one of the most popular race tracks among motorsport enthusiasts in China. Over the years many efforts have been put into introducing this race track to racing sims, but very few mods really do justice to the beauty of the circuit. My friend @jarod.yi started working on a new Tianma Circuit for Assetto Corsa from scratch back in July this year, and with what he has learned in his previous projects (West Fengdong and Minicircuit 迷你环道) now his work has started to shape nicely. He authorized me to post here about his progress in the making of this track, and download will soon be available when the race track is ready for a public release.

Beta version download links will be sent to donors for early access and testing.
