UK car tax is currently based on vehicle type- but it's based on CO2 emissions https://www.gov.uk/vehicle-tax-rate-tables

typically this is related to weight/size - except in the case of electric vehicles which are heavier than their ICE counterparts

This (and tax subsidies) is the reason behind the proliferation of large plug-in-hybrid SUVs - being a plug-in hybrid lowers CO2 emissions (at least on paper), but in practice many/most owners will never actually charge the car, so the CO2 emissions will be even more unrealistic than they already are.

This doesn’t address needlessly large EVs that damage roads and are a threat to pedestrians and bicyclists. These larger EVs are also inefficient use of battery cells than they’d be in smaller vehicles. Would love to see more Mini/Smart car EVs

A Tesla is heavier than a petrol Range Rover. All EVs are heavy.

The weight difference of comparable ICE cars and EVs is sometimes surprisingly small when you look at the variant of the EV model with the smaller battery.

For example, the BMW X3 is 1670 kg. The Tesla Model Y (SR RWD) is 1778 kg.

That's only for big cars.

The smallest Tesla is a D-segment car, cars around 4.7m: https://en.wikipedia.org/wiki/D-segment

There are 3 different car categories smaller than the smallest Tesla.

For smaller cars, EVs are a mess, they're between 25 and 40% heavier than equivalent ICEs, that's a humongous difference.

Well, they did say this:

> Would love to see more Mini/Smart car EVs

Teslas are big cars: https://en.wikipedia.org/wiki/D-segment, they're not Minis. The smallest Tesla is 4.7m long.

There are 3 car categories smaller than the smaller Tesla.

But yeah, EVs are heavy.

The larger an EV is the less efficient it is because it has to carry the unloaded battery with it, and it needs more battery for the same function. I don't have the number but I would bet that the energy need is a square of the vehicle weight. It's the same problem rockets have where they have to expend fuel just to carry fuel.

The Renault Zoe was a best seller in some countries because it's a great city car. Sadly Renault have cut back production due to diminishing margins due to supply chain issues (official version), which is a shame. There's also the Fiat 500 EV.

It's sad that MINI/Smart are no longer small.

Also, there was an article recently that (at least in US) the CO2 emission norms are not absolute but relative to car size; to the absurd point that to fit into the norms, it's easier to make the car bigger, rather than to lower the emissions of a smaller car. Hence, SUVs.

Absolute in the UK

I'm not sure I have seen many large plug-in hybrids on UK roads

Seeing more Volvo SUV PHEVs recently, big ones too.
Re:Britain's roads can't keep up with our cars by fomine3 on Thursday September 14, 2023 @03:18AM (#37505947)
PHEV shouldn't be sold to who don't have slow charging equipment at home. It's one of the best solution with home charger.
