You realise that on both a domestic and international scale, EV sales are continuing to grow whereas ICE is falling behind, both in terms of sold numbers and customers indicating that they will be looking to purchase an EV next. That last part is what is pushing EV sales on, manufacturers building what the majority of customers indicate they are looking for next, much like how its customers that drive manufacturers to churn out SUVs over anything else.
There’s less incentive to discount ICE vehicles as its shown they depreciate far more heavily than EV’s; in its first year an ICE vehicle deprecites by approximately 24%, an EV 12% hence the reason motability can discount higher priced EVs compared to their equivalent ICE counter parts.
