Which engine to choose for your car in 2022?

Combustion engine, hybrid or electric: which engine to choose? Asking yourself this question and finding an answer to it is crucial before you even buy a new vehicle. In a context where carmakers are doubling their imagination to offer increasingly efficient and economical models,
your budget, what you will use it for
i the environmental impact of the engine
these are all factors to keep in mind when thinking about buying your new car.

The 3 types of engine: internal combustion, hybrid and electric

To know
which engine to choose for your future vehicleIt is worth considering the different types of engines currently available on the market as well as their advantages and disadvantages.

A quick technical reminder is needed.

To be able to move forward, a car needs mechanical energy,
energy to be created from an element
. It is in this last point where the 3 types of engines are differentiated:
and are more or less polluting :

  • The internal combustion engine produces mechanical energy by burning fuel (gasoline, diesel or (G) az of (L) liquefied (P) etroli).
  • The electric motor produces mechanical energy from the electrical energy supplied by a battery or a fuel cell (hydrogen cars).
  • The hybrid engine works thanks to the 2 previous methods.

Now that the basics have been laid, let’s take a closer look at the different engines currently available in the car market in France.

Heat engines (gasoline, diesel, LPG double fuel, Bioethanol Flexfuel)

Also called
combustion and explosion engine, the heat engine needs fuel (the fuel) to run. Although the trend is green and
this engine is the most polluting
this type of engine is still the most widespread in the world.

4 different fuels

Internal combustion vehicles operate by burning fuel at very high temperatures. But it’s not just one type of fuel! There are 4 of them – two of which you are sure to know – (petrol, diesel, LPG, bioethanol).

Like the engine type, each fuel has its own set of advantages and disadvantages. This table is there to help you see things more clearly.

  • less expensive vehicle maintenance
  • more driving experience
  • higher consumption than diesel and LPG
  • faster engine wear
  • highest price at the pump
  • discharge of important fine particles

  • more robust engine than LPG and gasoline
  • consumes little
  • expensive maintenance (less than LPG)
  • significant CO2 emissions
LPG biofuel (Liquefied petroleum gas) / Gasoline
  • more environmentally friendly fuel
  • cheaper fuel
    to the bomb
  • periodic vehicle checks
  • higher consumption (up to 15% than gasoline)
Bioethanol E85 / Gasoline
  • fuel containing 85% plant-based ethanol
  • very attractive price at the pump
  • better performance and improved power
  • requires a stock or retrofit FlexFuel vehicle
  • higher consumption than gasoline

What to remember to know which engine to choose:

  • Gasoline engines are ideal if you drive little and especially in urban areas;
  • Diesel engines are ideal for long trips on a regular basis.
  • LPG / petrol dual fuel engines are suitable if you drive regularly and want to save energy and money in the long run. They are
    the most advantageous, either for its economic cost or for its environmental cost. However, keep in mind that
    LPG cars are more expensive to buy
  • Some petrol car models can run on bioethanol (E85). This alternative to SP95 and SP98 turns out to be
    extremely profitable– the price of fuel will rise – and much more environmentally friendly. However, the vehicle must be
    FlexFuel to be able to use E85: The list of supported original cars is limited.
  • LPG and E85 are the two most economical engine solutions
    especially for drivers who drive a lot.

Hybrid engines

Trend of the moment, hybrid engines combine thermal technology with electric technology: these are
cars with reciprocating engine.

Developed in 1997, the hybrid has not stopped renewing itself, now imposing itself, with the electric, on the French car fleet with
almost 20% market share

Vehicles powered by this type of engine fall into two categories:

  • Non-rechargeable hybrids
  • Plug-in hybrids – their batteries are 7 to 13 times more effective than non-rechargeable hybrid vehicles.

Even today, most hybrid vehicles, whether plug-in or not,
they mainly use their heat engine to advancethe electric motor is used only when the car is moving slowly or in very specific situations assessed by the dashboard.

electric motors

The electric motor is
the most recent. He is also the most “revolutionary”. To work,
an electric motor uses a battery
(while hydrogen cars use a fuel cell).

Advertised autonomy vs real autonomy (WLTP cycles), maximum speed, comfort … The performance of electric motors varies from one car model to another, so even before buying an electric car,
understanding its pros and cons is essential

What to remember:
Electric vehicles, although more expensive to buy, are the preferred solution if you want to drive “green”. However, before you buy a new or used electric vehicle, find out about:

  • the real autonomy of the car
  • the type of battery
  • the charging network
  • effective load power
  • charging time

Comparison of thermal, hybrid and electric motors

Advantages Disadvantages
Heat engine
  • technology still used mainly in the world
  • adapted infrastructure
  • more affordable prices and more developed offer
  • polluting engine (CO2 waste, fine particles)
  • ecological penalty for the most polluting vehicles
  • fuel cost
  • important maintenance of the vehicle
Hybrid engine
  • optimal fuel consumption (up to 23% savings)
  • driving comfort
  • more environmentally friendly than a combustion engine
  • regenerative braking system
  • excellent autonomy in rechargeable models
  • high purchase cost
  • limited trunk space (electric motor often located in the back)
  • high maintenance and insurance costs
  • cars heavier than thermal models
Electric motorization
  • (Very) economical consumption: 2 euros per 100 kilometers compared to 8 to 11 euros with combustion engine
  • more eco-responsible motorization
  • silent vehicle
  • different bonuses and help available
  • long-term profitable investment
  • slower wear, less maintenance required
  • high initial purchase price
  • limited range long distance
  • variable cooling

So which engine to choose for your car in 2022?

Finally, the engine you choose will depend on several factors,
3 in particular :

  • Your use
  • Your budget
  • The environmental impact of the vehicle

Drive long distances regularly and your budget is limited. The diesel car turns out to be a good choice. However, be aware of the vehicle’s Crit’Air sticker!

You drive mainly in the city and plan to go on holiday with your car. If you can afford it, opt for an electric or hybrid vehicle. Otherwise, choose a dual-fuel gasoline / LPG engine.

Want to reap the benefits of gasoline while maximizing your fuel costs:
choose a FlexFuel vehicle. You will be able to fill your tank with Bioethanol E85, a considerably more environmentally friendly and economical unleaded petrol fuel.

You have enough money to invest in a new vehicle (over € 20,000), you can invest in an electric vehicle. Your purchase will pay for itself over time, with electric motors being the cheapest.
