I've heard some things about this car.
Took this information with a large grain of salt (I don't really know this source).
*A target weight of less than 1200 kilos.
*A very Valkyrie AMR Pro front with a bit of Regera.
*Higher engine speed (9000 RPM).
*A power of 1440 Hp (Engine still under test).
*A removable roof that apparently doesn't fit in the trunk, unlike the RS.
*A tiny bit of hybridization.
If this information are true, it's gonna be crazy.
