The track only variant of the Valkyrie called the Valkyrie AMR Pro was introduced at the 2017 Geneva Motor Show.
Only 25 units will be produced, all of which have already been sold.
The AMR Pro uses the same 6.5-litre naturally-aspirated V12 engine as used in the Valkyrie road car along with the Rimac Energy Recovery System, although the KERS system will be reprogrammed in terms of its control systems.
The engine will also be modified, which means the AMR Pro will have increased engine power output figures than its road legal counterpart.

The AMR Pro uses smaller 18-inch wheels at the front and rear.
This is to allow the Michelin racing tyres (based on LMP1 race cars) to actually fit the car, with F1-inspired carbon-carbon brakes to aid braking performance.
The air-conditioning system and infotainment screens have been removed, and have been replaced with racing counterparts.
The car will be able to generate 3.3 g lateral force during cornering and 3.5 g during braking.
Its top speed is intended to be higher than the road car, at 402 km/h (250 mph).
The car's exhaust will have very minimal parts to silence the engine.

The AMR Pro will have a significantly more aggressive design, with a LMP1-style rear aerodynamic fin, a large dual-element rear spoiler, and a large rear diffuser.
