It's all just rhetoric until we see the start of a test program but now Abarth boss Paolo Gagliardo has been quoted on the subject of an entry into the WRC:
"Gagliardo also confirmed that the Fiat brand wants to make a return to rallying, and while it was initially suggested that the Abarth 124 Spider would be the favoured choice to enter the World Rally Championship, a performance-inspired 500X would be another option."

It all seemed a bit odd that the 124 Spider would be used "for a return to the WRC" - which to me suggested a works effort - but with a car that would most likely have been an R3 to rival the Toyota GT 86 CS-R3. A 500X-based Abarth seems more likely as that would be the most logical of their current lineup from which to make a World Rally Car.
