The Swede said his decision to step back to WRC 2 was driven by the WRC’s environmentally-friendly hybrid future, which will begin in 2022.

“If you look at the rally sport now, there are very exciting things coming in 2022, and it is important to stay in the sport and perform well. Going back and driving an R5 car offers the opportunity to drive more and to challenge for wins. That’s why we choose R5 in 2020,” he explained.

Tidemand, who will be co-driven by Patrik Barth, admitted 2019 was a tough year.

“We have been competing in WRC 2 for four-and-a-half seasons and felt that in 2019 it was time to take a step up and try WRC.

“So we did four rallies together with M-Sport Ford, but it was not easy to get into today's cars and be able to push them to the max with their advanced aerodynamics. It takes a lot more time behind the wheel of those cars,” he said.
Interesting comment at the end.
