In my view, M-Sport has made a huge step in securing manufacturer interest for rallying. Rallying is a method of developing technology and marketing the cars, and if the car manufacturers are going electric, they are not going to be interested in putting their money in combust engine rallying. Instead, electric rallying could spark up interest in new manufacturers.

At the same time, this change won't happen overnight, maybe not even in a decade. The technology is still new, especially to the sport. Even if WRC became all electric, all the combustion engine rally cars would not disappear and would most likely be used in historic/clubman rallies as long as there's some liquid to burn in them.
