Study points to plug-in hybrid cars ‘scam’

It is certainly a study which opens doors and probably serving as justifications for the actions carried out following that by the canton of Valais, in Switzerland. Indeed, after the publication of a report which showed that plug-in hybrids offered little benefit in terms of emissions and fuel consumption on mountainous roads, the township simply removed the subsidies intended for these models.

This study was carried out at the request of the Valais authorities by the company Impact Living, a company which is active as an assistant owner. According to this study, “the quantitative results (measurements of actual fuel consumption) show that plug-in hybrid vehicles fall far short of their promises and offer only very slight advantages (if any) compared to a conventional combustion engine”.

One of the study’s authors, Marc Muller, an energy engineer, told Swiss public radio RTS that these vehicles are “a CO standards scam2, climate goals and consumers! “.

The study shows that plug-in hybrids, in the reality of the topography of Valais, a very mountainous region, “emit up to almost four times more CO2 that announced “ by the builders. According to the study, “even a driver with charging stations at home and at work and making short trips does not reach the values ​​of the manufacturers”.

“Hybrid vehicles are often advertised by manufacturers as 1.5-2.5 liter vehicles per 100 kilometers, but in reality they consume between 4 and 7 liters, like Diesel vehicles.”, underlined Marc Muller, at the RTS.

In 2020, the NGO Transport & Environment, which analyzed the behavior of three of the best-selling models this year, had already affirmed the CO emissions2 plug-in hybrid vehicles remain superior to what the manufacturers officially announce.

Studies by the NGO International Council on Clean Transportation (ICCT) have also concluded that CO emissions2 in real conditions plug-in hybrids were generally higher than the measurements communicated during their approval process.

For many experts, the plug-in hybrid combines the worst of the two worlds, namely the drawbacks of heat engines (air pollution) and those of electric motors (high weight and price due to the two engines).

When they are not regularly recharged, these cars suffer from very high consumption. But, used correctly, and for some drivers who combine long distances on highways and urban use, the plug-in hybrid remains an alternative to diesel, fallen out of favor since the scandal of the rigged engines of Volkswagen.
