A Prius will definitely pollute less than the typical SUV electric cars on a coal grid.
Cause:
Efficiency of coal power plant and all losses are as bad as ICE cars. The EVs do thermal->mechanical->electrical->grid->battery->wheels and if you count them all up, is not better than an EV
Prius is designed for low drag unlike an SUV
Prius had regenerative braking like an EV
But just the numbers:
Prius is rated at 94g/kg
Coal 950g/kwh
Volvo c40 0.2kwh/km or 190g/km even without losses
Even with the current EU energy mix, it takes 77’000 km to be better than ICE, so arguably better. On coal electricity, they are worse. And this is comparing equally sized cars, a Prius will do better.
Regardless of the accuracy of your numbers - If you fix the ICE cars as they wear out, replacing them with BEV as the energy grid retires coal plants or goes to a higher percentage of renewables, they get cleaner. ICE cars will be as dirty tomorrow as they are today.
That is true. I do think we should retire pure ICE cars as soon as possible. If you need to do long distances, a hybrid that could be converted might be a good intermediate solution. If you only need a car sporadically, a car sharing platform with electric cars is a good solution. These already exist in big eu cities. Ofc good and adorable public transport is nr 1.
Decreasing the amount of cars would decrease emissions short and long term more than the current shift to EV and would make shifting easier as there are just fewer to replace.

I took Volvo cause they published a report with a good compare ev and ICE https://www.volvocars.com/images/v/-/media/market-assets/intl/applications/dotcom/pdf/c40/volvo-c40-recharge-lca-report.pdf
