The Race of Champions will be hosted in North Sweden for several years, starting in 2022. Not sure about this, because it's a silly little show but the most recent event in Mexico did attract both Vettel and Gasly. Hosting it on the snow in Sweden will surely attract rally royalty such as Loeb, but might struggle to bring in drivers who prefer the grippier stuff.

They just do it for fun anyway, it might even attract more drivers.
I think Sweden's a pretty small country, and I live about 5 hours away from our Southermost point. And Pite Havsbad is a 10 hour drive from here. So I guess we're not that small a country.
Almost twice the size of the UK, so not small in my mind! Only about one seventh of our population though, so clearly room to grow....
