If anything, speed wise, these new cars a bit of a downgrade, but better cost budgets, more work from manufactures and more manufactures in general would help the sport greatly.
Yes, the sport just needs more teams. And without such a development of technology, which will throw out gasoline engines and completely replace them with electric ones. Then it wouldn't be a rally anymore...
All the tires have barcodes that officials can scan to make sure they aren't trying to fit different tires they left the service park with, or aren't controlled by FIA.
Previous WRC Yaris has aerodynamic fins behind the back wheel and seems help a lot for high speed turn and stability. Current model is also good but it seems to me slower than 2019 - 2020 models .. my humble opinion and personal observation ..
