 Di Grassi ignored Buemi's criticism and clarified his right-rear suspension was damaged from his contact with Abt instead of Buemi's hit as had been initially reported by Audi.It was discovered after the race that several drivers had poor radio reception due to the local skyscrapers, prompting them to recalculate their regeneration and electrical energy usage without assistance.Abt likened the situation to Formula 4 racing while Piquet believed he could have improved on his fourth-place had his radio functioned correctly.
