This variant of the Xspeed ZX is a track only version, set up specifically for the Nordschleife (on slower/smaller tracks like shukudo island, it actually isn't that good)
The car weighs only 1100kg due to weight reduction and unlike the road versions of the ZX that have a turbocharged 2-liter Koyote/Nero sourced engine, this one has a 3l 20V inline 4 turbo race engine, making 570hp two the rear wheels through a dualclutch transmission. It creates much downforce due to improved aerodynamics and also has wider tires with race slicks and race breaks.
It is a limited Edition and only avaiable in British Racing Green.
Here you can see it in it's natural habitat:
