In recent years, new uses of the car and new regulations have pushed manufacturers to innovate to obtain ever more efficient engines and to explore new energies to propel cars. In addition to the historical petrol and diesel engines, alternative engines have appeared to meet the needs of drivers. Here is an overview of the energies available on the automotive market.
Diesel acclaimed by big wheelers
Until recently, diesel cars were the best-selling vehicles in France. Despite a purchase cost often higher than other engines, diesel cars compensated with a more reasonable cost per liter and lower fuel consumption. Nevertheless, in recent years, the trend has reversed following many regulatory changes. Major advances in other energies: less fuel-consuming petrol engines, electric motors with greater autonomy.
Despite everything, diesel cars remain a relevant choice for drivers who have an annual mileage of more than 25 / 30,000 km. Indeed, the lower diesel fuel consumption of these cars allows a high range. It is usually the choice of road professionals who favor diesel also for additional tax benefits and for a sales value that does not discount as fast as other engines.
Gasoline, the most economical to buy
The car with a gasoline engine is most widespread among general manufacturers. Indeed, it combines a reasonable purchase cost, maintenance, and insurance often cheaper than a diesel car. This difference is also visible in used gasoline vehicles that will be more affordable. Petrol engines will be more suitable for small drivers who make between 10,000 and 20,000 kilometers per year.
Beware, however, the purchase of a gasoline vehicle is not without rewards: unleaded fuel remains the highest at the service station. Also, environmental taxes are particularly aggressive on these engines because they emit a lot of CO2.
Green energy cars: electric and hybrid
Currently, in the automotive market, there are three types of “green” powertrains: electric cars, hybrid cars, and plug-in hybrid cars. Unlike conventional combustion engines, these engines are said to be green because they use electricity rather than conventional fuel to operate and they do not release or little CO2 into the atmosphere.
100% of electric motors are only equipped with batteries to move. Thus the autonomy of the vehicle is related to the power in kWh of the battery that must be recharged at terminals to obtain the necessary energy. Hybrid cars, on the other hand, combine an electric motor and a gasoline engine. For conventional hybrid vehicles (therefore non-rechargeable), the electric battery is recharged during the braking or deceleration phases of the vehicle. The electric motor is often running at low speed and passes the relay to the heat engine at a higher speed. For plug-in hybrids, the system is similar, simply the vehicle has a plug on the side of the car to charge the vehicle faster at terminals or home.
