As I said in a other post, it could be a typo..or .. It’s to offset the £15k levy for ICE cars over their quota. It will be the same for other ICE cars, not just Stallantis. Carrot and Stick to move everyone over to EV,s. This year its 22% EV,s an I think its 29% for 2025, something like that. But the amount of vehicles on the scheme stay the same.
It can’t be that as these cars are PHEVs, not pure ICE cars (not that it would be that anyway)
