After a whole series of negotiations, there seems to be a general easing as regards the very tight restrictions of the future Euro 7 engine. Let's find out together what has happened in the last few days and months.

As we all know, sustainable mobility is the goal of every single citizen with good rationality within the European territory. Having a passion for cars must still take into account a fundamental force, namely that of nature.

In fact, cars are carriers of about 25% of the forms of air pollution within the old continent. For this reason it is essential to try to develop engines that are, yes, high-performance, but also take into account the emissions produced as quickly as possible.

For this reason, the European Commission has gradually developed over the years quality standards in terms of emissions. Here is therefore explained what the acronym euro 7 means. Over the years the European Commission has gradually highlighted the standards that have taken the name for the specification of Euro 0, Euro 1, Euro 2, up to the current Euro 6.

The next step is obviously Euro 7 and should come into effect in 2025.

The European Commission had feared of the truly excessive forms of limitations according to all car manufacturers. Even politics had expressed itself against these excessively restrictive limitations, as it was almost an unnatural process.

It was really impossible in some cases, to develop engines with such small emissions. To understand for a moment, the nitrogen oxide limit was initially expected to be 10 mg per km, but it is now assumed that it should be raised to between 25 and 30 mg per km.

There is also talk of a general lightening with regard to homologation, as emissions in particular conditions were taken into consideration. There are so-called transitional phases, which are for example the cold phase and short journeys and which should be included in a cycle.

Almost all the people who have a certain weight at European level, both in technical and in political terms, have therefore expressed a clear opposition to these excessive limitations.

Of course we all would like to live in a pollution-free world, but we still have to consider the fact that mobility is now an essential factor. If it is true that Smart Working has developed considerably, we all know that in some way in everyday life we have to move. The electric is not yet ready to completely replace thermal engines, but the transition objectives have already been set in terms of date.

By 2035, all cars sold should be zero-emission and by 2040 trucks should be too. The euro 7 standards should therefore be the last or the penultimate standards for heat engines. It must also be said that there is a huge audience of people who push on thermal engines with synthetic fuels. The latter, however, have a very low energy yield, around 15 or maximum 20%. For example, let's consider that an electric motor has a yield of 70% and therefore we quickly understand which of the two is more efficient.

We will therefore see what the future holds.
