What are the competition parameters of WRC?

WRC racing cars must use the standard body of production cars. Most WRC racing cars can support the weight of 10 ordinary cars. The FIA requires all WRC engines to install a throttle with a size not larger than 34 mm at the air intake, and limit the power of the racing car to 300 HP.

The engine block and cylinder head must be equipped with standard civilian vehicles. The standard turbine equipped with the racing car can push the air pressure of 4-5 bar. In contrast, the pressure of ordinary civilian vehicles is only 1 bar at most. The car is also equipped with a time delay system, which allows the turbocharger to release the maximum propulsion from the beginning. These changes have brought huge torque-700 Newton.

The modified car can start in three seconds and accelerate to 60 mph-provided that the racer is familiar with the performance of the car-and the car can slide between two trees at a speed of 200 km/h on the narrow gravel road, and ensure that the racer can still fully control the car at this speed.
