We'd still call a genuine off road vehicle a four by four. Americans have gone a bit nuts with the SUV label - we don't call things like a Model Y an SUV, it's just a hatchback. Some other models Americans call SUVs are Estates or People Carriers. We probably wouldn't call things like a Porsche Cayenne a 4x4 because it's never going off road. That will happily be called an SUV with all the selfish egotism implied. Other names for it would be more deliberately insulting e.g. Chelsea Tractor etc.
