Some, including the European Union, criticize plug-in hybrid cars for their lack of efficiency in real driving conditions. However, these engines constitute an excellent alternative to the electric vehicle if you know how to take advantage of their technology. Decryption.
Plug-in hybrids, an ideal compromise?
Hybrid cars are positioned as a compromise between traditional thermal vehicles and 100% electric cars. They combine the best of both worlds:
If non-plug-in hybrids and micro-hybrids are very successful, particularly in Spain where they give access to the “ECO” ecological badge, plug-in hybrids live in a gray area. They certainly constitute a very good alternative to pure electrics, but are also the subject of numerous criticisms.
Real consumption far from approval figures
The main difference between a conventional hybrid and a plug-in hybrid lies in the power of the electric motor and the capacity of the battery, which recharges from an outlet like an electric car, but with reduced charging times.
This technology has made it possible to develop cars with average consumption of less than 1 L/100 km and electric ranges exceeding 100 km. They also benefit from the “Zero Emission” badge, tax advantages and purchasing assistance such as the MOVES III plan in Spain.
But many, including the European Union, question the relevance of this technology. Some even advocate the end of plug-in hybrids. Studies, such as this report from the European Commission last March, show that approved consumption figures are unattainable in real use, which increases polluting emissions and calls into question the efficiency of these vehicles.
Plug-in hybrids, heavier and less fuel-efficient than announced
The Commission's study points out the excess weight of plug-in hybrids (2021 kg on average) compared to conventional thermal engines (1554 kg). Added to this is the enormous gap between WLTP approved consumption and the actual figures:
The reason ? Underutilization of the potential of the plug-in hybrid engine. Driving with an empty battery using only the combustion engine in a heavy car causes consumption and emissions to skyrocket.
Using your plug-in hybrid properly, instructions for use
If an electric car requires planning to avoid running out of fuel, a plug-in hybrid also requires anticipating frequent recharging to minimize the use of the thermal engine alone.
The mistake not to make is buying a plug-in hybrid for long motorway journeys. These vehicles are more efficient in town, where electric autonomy is better exploited.
Going on a trip in a plug-in hybrid is possible, but without a battery and with the excess weight of the electrical components, consumption will be higher in 100% thermal mode.
Relevant technology for the right profile
Despite current criticism, plug-in hybrid technology is ideally suited to a specific type of driver: those who mainly drive in the city on a daily basis and occasionally take long trips.
While most electric vehicles on the market allow this dual use, plug-in hybrids are an excellent choice for those who are hesitant to take the plunge. They also have the merit of replacing old, inefficient thermal cars.
So of course, plug-in hybrids are singled out, but provided their technology is used wisely, they have their place in the current automotive landscape, while waiting for 100% electric. To the wise!
