Which engine should you choose for your car in 2022?

Internal combustion, hybrid or electric motor: which motor should you choose? Asking yourself this question and finding an answer to it is essential 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 are going to use it for
and the environmental impact of the engine
are all factors to consider when the time comes to think about the purchase of your new car.

The 3 engine types: combustion, hybrid and electric

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

A quick technical reminder is in order.

To be able to drive forward, a car needs mechanical energy,
energy to be created from an element
. It is at this last point that the 3 types of engines are different –
and turns out to be more or less polluting :

  • The heat engine produces mechanical energy by burning fuel (petrol, diesel or (G) az of (L) liquid (P) etroleum).
  • The electric motor produces mechanical energy from 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 various engines currently available on the car market in France.

Thermal engines (petrol, diesel, bi-fuel LPG, Flexfuel bioethanol)

Also called
internal combustion and explosion engine, the heat engine needs fuel (the fuel) to operate. Although the trend is green and
this engine is the most polluting
This type of engine is still the most widely used in the world.

4 different fuels

Combustion vehicles work by burning fuel at very high temperatures. But there is not just one type of fuel! There are 4 – two of them you need to know – (petrol, diesel, LPG, bioethanol).

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

  • cheaper maintenance of vehicles
  • more driving experience
  • higher consumption than diesel and LPG
  • faster wear on the engine
  • highest price at the pump
  • emission of significant fine particles

  • more robust engine than LPG and petrol
  • consumes little
  • expensive maintenance (less than LPG)
  • significant CO2 emissions
Bi-fuel LPG (Liquefied Petroleum Gas) / Petrol
  • most environmentally friendly fuel
  • cheapest fuel
    at the pump
  • regular car checks
  • higher consumption (up to 15% than petrol)
Bioethanol E85 / Petrol
  • fuel containing 85% plant-based ethanol
  • very attractive price at the pump
  • better performance and improved power
  • requires stock or retrofitting of FlexFuel vehicle
  • higher consumption than petrol

What you need to remember to know which engine to choose:

  • Gasoline engines are ideal if you drive a little and mostly in urban areas;
  • Diesel engines are ideal if you regularly take long trips.
  • 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, whether it is for their economic costs or their environmental costs. Remember that though
    LPG cars are more expensive to purchase
  • Some petrol car models can run on Bioethanol (E85). This alternative to SP95 and SP98 turns out to be
    extremely profitableThe price of fuel is set to rise, and much more environmentally friendly. However, the vehicle must be
    FlexFuel to be able to use the E85: the list of original compatible cars is limited.
  • LPG and E85 are the two most economical engine solutions
    especially for drivers who drive a lot.

Hybrid engines

Trend at the moment, hybrid engines combine thermal technology with electrical technology: these are
alternatively driven cars.

The hybrid, developed in 1997, has never stopped renewing itself, and is now imposing itself, with the electric, French car fleet with
almost 20% market share

Vehicles driven by this type of engine are divided into two categories:

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

Even today, most hybrid cars, whether plug-in or not,
primarily use their heat engine to get aheadthat the electric motor is only used when the car is driving slowly or in very specific situations assessed by the dashboard.

electric motors

The electric motor is
the latest. It is also the most “revolutionary”. Working,
an electric motor uses a battery
(while hydrogen cars use a fuel cell).

Advertised autonomy vs actual autonomy (WLTP cycles), maximum speed, comfort … The performance of electric motors varies from one car model to another, which is why even before you buy an electric car,
It is important to understand its pros and cons

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

  • the car’s real autonomy
  • type of battery
  • the charging network
  • efficient charging power
  • let time

Comparison of thermal, hybrid and electric motors

Advantage Disadvantages
Thermal motor
  • technology that is still mainly used in the world
  • adapted infrastructure
  • more available prices and more developed offers
  • polluting engine (CO2 rejection, fine particles)
  • ecological punishment for the most polluting vehicles
  • fuel costs
  • important maintenance of vehicles
Hybrid engine
  • optimal fuel consumption (up to 23% saving)
  • driving comfort
  • more environmentally friendly than a heat engine
  • regenerative braking system
  • excellent autonomy on rechargeable models
  • high purchasing costs
  • limited luggage space (electric motor often located at the rear)
  • high maintenance and insurance costs
  • heavier cars than thermal models
Electric motorization
  • (very) economic consumption: 2 euros per. 100 kilometers compared to 8 to 11 € with an internal combustion engine
  • more environmentally responsible motorization
  • silent vehicle
  • various bonuses and aids available
  • profitable investment in the long run
  • slower wear, less maintenance required
  • high initial purchase price
  • limited long-range range
  • variable cooling

So which engine should you choose for your car in 2022?

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

  • Your use
  • This budget
  • Environmental impact of the vehicle

You regularly drive long distances and your budget is limited. The diesel car turns out to be a good choice. However, take into account the vehicle’s Crit’Air label!

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

You want to take advantage of the benefits of petrol while optimizing your fuel costs as much as possible:
select a FlexFuel vehicle. You will be able to fill your tank with Bioethanol E85, a unleaded gasoline fuel that is significantly more organic and more economical.

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