The PHEV market is still outperforming not only the ICE market but also BEV market, whether it is for new registrations or for used imports.
New registrations are up 8% but volumes are low like any month of June. However the more surprising fact is that used imports are up 87% (Diesel are down 53% and petrol down 38%). In June, for every 5 petrol import, 1 PHEV was imported, and the ratio is at 13 to 1 if you compare PHEV to Diesel. If 13 to 1 sounds still high for you, just think that in June 2019 that ratio was at 49 to 1 ! PHEVs are no longer a niche market.
This month, the BMW X5 is leading the new sales, and the Mercedes C350e is on top of the used import list.
