Cars of World Rally Championship

Today we are going to discuss about the FIA WRC (World Rally Championship) Cars that are stripped from a basic Road Legal version to a bare metal shell before completely rebuilding it. WRC Cars are based on the standard Road Legal versions and are identifiable with the type of Car that you buy from your local dealership and that is where the similarities stop. These Fire-Spitting Machines are capable of astonishing achievements on surfaces ranging from rocky and pot-holed dirt tracks to twisty and narrow asphalt lanes. Even rutted roads covered in snow and ice; and reigning supreme in such surfaces with capability of achieving Top Speeds exceeding 200 km/h with ease.

These Cars must maintain peak performance in different conditions where temperatures can swoop down to -30 °C at one round and soar to 30 °C on the next.

So today we will be getting into the certain technical data which will make you easily understand why are these Cars so PowerFULL. The specifications of these Cars differ from each other based on the different categories. There are four categories in World Rally Championship :

  1. WRC
  2. WRC2
  3. WRC3
  4. JUNIORWRC

But out of the four, we shall discuss only two categories, the fastest out of the four and the most basic of them. Fastest being the WRC and the JUNIORWRC being the most basic one.

This once again proves that Motorsports first pushes the limits of a vehicle and it’s components to go fast, which gradually in funneled down to us. Technology proved, tested and passed through the toughest assessments just to keep us Mortal, Normal beings safe.

With this we conclude our article and hope we further increased the depth of your Automobile and Motorsports Vision.
