An ICE 718 would have side air inputs. Maybe those could be hidden under the car or from the front on this mule. But the original poster an another forum, who took these photos, didn't mention any engine noise. He was pretty sure those two are electric.

The yet-to-be-abandonned(?) 718 EV got spy-shot-ed during a test in France (with a Macan EV following it). Still disguised, the rear looks too squarish to be the real deal :
