A few surprises here, namely that PHEVs will pay a lower rate of RUCs, I was under the impression there would be a rebate scheme for petrol purchased.
No revisions to the weight brackets, which I imagine will be necessary before all vehicles eventually go to RUCs.
The rebate scheme for PHEVs would make more sense, as the amount of petrol they need can vary wildly depending on the battery size and average trip distance.
I wonder if you add a generator to your EV to make it into a PHEV, do you then pay less RUCs?
I can absolutely see why they went with a lower rate of RUCs though, what they were proposing would have been a nightmare to administer, and a pain in the ass for owners.
