Jump Jacks

The car is equipped with four jacks at each corner that can thrust the car into the air on command. They can be activated all at once or on the left or right independently.

Engine and Drivetrain

Most cars use piston engines for their mechanical energy generation. The engine generates rotary motion by deflagrating fuel inside its combustion chambers to drive pistons. The fuel is a conventional racing gasoline mixture homologated by the WRL. The engine is mechanically linked through a driver-operated clutch to a manually-shifted six-speed gearbox and final drive, which can be reconfigured to the driver's gear ratio preferences. It is further connected through a center differential to a front differential and rear differential powering each wheel through a flexible mechanical connection.

Some cars may use non-piston engines to generate torque. They may use rotary engines, gas turbines, or other, more exotic means of generating rotary motion.

Integrated Turbine

Most cars use a low-inertia turbojet engine to provide direct thrust output at the rear of the car for enhanced cornering and extra acceleration. The turbine contains a bleed-air system which, much like a turbo- or supercharger, can deliver pressurized air to the piston engine for extra power, though the turbine must be spun up for this boost pressure to be developed. The turbine can be shut down entirely during times when rearward blast thrust may be dangerous to the pit crew by flipping the fuel pump control.

As an alternative to a traditional jet turbine, some cars might use larger-than-normal turbochargers to bias towards boost generation instead of thrust. These cars may still produce thrust through a form of evolved anti-lag wherein fresh fuel is fed to the turbine wheel exhaust inlet, which is specially shaped to act as a secondary thrust-providing combustion chamber.

Wheel Steering Controller

The wheels are controlled independently of each other via servo motors commanded by the car's central computer. The computer can detect each wheel's slip angle, or "angle of attack", and can steer each wheel to a specified offset of that angle. Angle offsets are calculated through an algorithm that takes the car's yaw rate and the driver's steering angle as inputs. On entry to a corner and upon steering input, the wheels are steered to change the car's yaw rate. Holding the wheel straight instructs the system to hold the current heading. Steering into the corner will aim the chassis more towards ths apex, countersteering will reduce the drift angle and straighten the car's trajectory, pointing it towards the outside of the corner.
