I guess you meant direct-injected gasoline engines, which in most cases follow the downsizing bandwagon. Well, no wonder Toyota seems to be still committed to port injection and natural aspiration in entry-level models instead of fully embracing the downsizing, at least they can keep it simple and avoid the expenses of adding a particulate filter. BTW the first gasser I saw which was fitted with a particulate filter is the Volkswagen Tiguan Allspace, which according to some sources got this feature as an attempt to whitewash Volkswagen's reputation in the Dieselgate aftermath.
