how to choose in 2022?

Faced with the multitude of engines available in 2022, it is not easy to get your bearings and make the right choice. We guide you through the available options!

In 2022, the supply of engines in new cars has never been so rich. Certainly, diesel is on the way to the top, but it is still offered by many manufacturers. And petrol, micro-hybrid, classic hybrid, plug-in hybrid, electric, E85 and LPG offerings abound and co-exist. As a result, it is not always easy to find your way around and buy the engine that will best meet your specifications at least as much money as possible. We take stock.

Gasoline: the safe bet

For most manufacturers, conventional gasoline internal combustion engines are still the cheapest of the ranges. Especially since they are often the only ones available in manual gearboxes, which are even cheaper than automatic ones.

Technological progress compels, gasoline engines are increasingly economical and less and less polluting. And if they are Euro 6D-Full certified (the standard currently in effect), you won’t be stuck in urban areas for many years (2030 minimum in Paris) and not before 2035 in France. Enough to ensure you can resell your new car in a few years without worry.

But beware, the species will become rarer, due to the tightening of standards. And non-hybrid essences are the most affected by malus. Don’t forget the latter when buying your car.

Diesel: not dead yet

Since the famous Dieselgate and the tightening of anti-pollution regulations, diesel has had a difficult life. Of the majority in sales in France, diesel represented only in 2021just over 20% of sales. With the famous ZFEs and traffic restrictions regulated by Crit’air’s vignettes, the days of diesel in big cities are numbered. Of course, many manufacturers decided to abandon it.

But outside urban areas, diesel still has its way. First, at equivalent power, it tends to emit less CO2 than gasoline. The penalty is therefore less. Above all, consumption is lower, even though the price of a liter of diesel is no longer much lower than that of gasoline. In addition, German awards still tend to offer it on models destined for great pilots.

Micro-hybrid: an affordable compromise

To deal with increasingly stringent emission standards without exorbitant costs, manufacturers often turn to micro-hybrid. This technology, often made up ofa small 12, 24 or 48V battery, allows the combustion engine to be turned off more frequently. Some even give you a little boost in acceleration and can turn off the heat engine when you lift your foot. City fuel economy is usually great, but make no mistake: it’s a trade-off. You will be far from the liters saved of the “full hybrids” and you will not be able to drive in 100% electric mode.

Classic hybrid: the most rational?

With pioneers like Toyota and Honda, “classic” hybrid technology is already well established. One or more electric motors replace the heat engine at low speed and in the city, and support it in the acceleration phases. The latter may therefore be smaller. Consumption is therefore logically reducedand that much more than in a micro-hybrid.

Compared to the plug-in hybrid, the classic hybrid offers generally lower prices and, above all, fuel economy in all conditions. On the other hand, driving in 100% electric mode is often restricted to a few kilometers, the failure of a small battery. Also beware of variable speed gearboxes (and equivalents which are often fitted to these engines and which are not always pleasant to use.

Plug-in hybrid: beware, very specific uses

Benefited from a WLTP certification cycle that makes them ridiculous consumption, plug-in hybrids are taking up more and more space in manufacturers’ ranges. And, on paper, they represent an attractive solution. With 100% electrical autonomy generally oscillating around 50 km, they can allow you to make your daily commute (home-work, shopping, etc.) without consuming a drop of gasoline. And when it’s time to go on vacation, you won’t have to queue in front of a charging station.

But now, these advantages only apply to a very specific situation. In fact, you must constantly recharge your PHEV’s battery to benefit from reduced consumption. Otherwise they can do much worse than a classic thermal! So, study its uses well before starting. Can you recharge at home and at your place of work? Do you often go on vacation or go long distances?

Electric: the future, but at what cost?

Touted by manufacturers and authorities as the engine of the future, electric vehicles are on the rise. Sales are exploding (but still in the minority), communication campaigns are multiplying… And we must admit that in everyday driving, electricity is very attractive. The instant torque is ideal in the city and the silence very pleasant on longer journeys. The a pedal mode that equips many models is an additional comfort. Not to mention, of course, the fuel economy and the ecological aspect, even if this is sometimes debatable.

But the price of electric cars is still very high. The charge price only increases. And not to mention the network of terminals, which is still very insufficient given the autonomy that struggles to exceed 350 km on the highway.

E85 and LPG: smart alternatives

In these times of completely crazy fuel prices, the alternatives are more interesting. Whether LPG (Liquefied Petroleum Gas) or E85 (Superethanol Produced Mainly from Beetroot in France), pump prices are displayed below €1/L. Unexpected! Unfortunately, these two engines are still rare. Dacia and Renault have invested in the LPG market, while Ford offers several models in the E85. On the other hand, in both cases, these engines are usually available in low power (100 hp, for example, from Dacia and Renault). But that makes it an entry-level smart!
