Hybrid cars with battery packs capable of charging via the power outlets pollutes the air 7 times more than 100% EVs. That is the conclusion made by Electric Vehicle Association Scotland after the research they’ve carried – read further for details and figures.

In order to carry the research the examinators took most popular models from each side: Nissan Leaf played on the EV field, while Mitsubishi Outlander PHEV was examined as a typical plug-in hybrid. As a result, it turns out that a year of city use with a mileage of 10,000 miles (16,000 km) made Leaf to generate about 1.12 tonnes of greenhouse gases, while Outlander’s polluted the air more heavily – with 8.42 tonnes.

Researchers also stated, that it is possible to reduce the amount of greenhouse gases plug-in hybrids generate for 2-3 times if 90% of their whole mileage will be covered using only electric power. However, that is technically impossible due to the lack of range PHEVs batteries provide – as for today, such vehicles cover only about 40% of entire mileage this way.

By the way, the share of plug-in hybrids in the whole amount of EV sales is quite stable since 2014 and stays around 40%.
