5 concerns for the future of the diesel engine in Spain


The succession of bad news -or negative – around the diesel engines can cause understandable concern and distress to those who already have a car with that technology, or are waiting to buy another. The diesel is not finished, but is in a delicate situation.

The petrol engines have been recovered a lot of ground, and can be inexpensive (and with a total cost very similar) with performance equal to those of the oil tankers. On the other hand, alternatives increasingly have strength, having more range of possibilities.

Is it silly to buy a diesel today? Not necessarily.

1. I will drive with my diesel?

In road toll, there is no forecast of that there will be changes. It is in certain municipalities where there will be circulation areas limited or prohibited according to environmental criteria. Depending on the classification Euro, the limitation will be lower or higher.

In the low-emission zones (ZBE) there is the anticipation of a veto to the entire circulation -with some exceptions – of the diesel and conventional gasoline in other areas will depend on the quality of the air. If we move out of the big cities, the urban centres are small and medium-sized will not hit it for years.


In the Community of Madrid have been expected to speed limits on roads if the contamination was triggered, but not prohibition of circular

2. Will taxes be increased?

it Is quite likely that the litre of diesel has a tax system less favorable and the price is closer to that of gasoline. It can also be the case that there sorpasso, as has already happened a couple of times, at least in a timely manner. The threshold of profitability of a diesel will take longer to be achieved.

on the other hand, it is possible that the road tax (TAX) change its tax and to leave is to be taken into account displacement and number of cylinders. It is a classification that made sense years ago, but each time less, since the majority of cars sold have less than 2 liters. You have more logic that values the standard anti-pollution of each model.


3. ¿They are going to stop manufacturing them?

In the segments subcompact compact and virtually going to disappear. As every time is less cost effective a diesel engine in those categories, and the gasoline return to be the leaders, there will be less to choose from. Starting in September, with Euro 6D, there will be a small extinction in several manufacturers at the same time.

will Remain for a time in the sedans stockings, SUV, suvs and large vehicles, while the market share to justify it. Progressively will be replaced by semihíbridos or hybrid of gasoline, and later by pure electric or plug-in hybrids with gasoline engine.


In the long term, just the electrical will be able to move with freedom in any scenario, because it does not produce local emissions

4. How those already enrolled, will be banned?

Not, they are talking about preventing the enrolment of new cars from certain dates, depending on the city or the region. Vehicles that are already enrolled may continue to circulate, at least on the roads. In the urban tract will depend on the city council and its policies against air pollution.

vehicles that have more than 30 years (historical) will be able to have a more friendly than those of lower age, as it has been done for example in Paris. In terms of the low-emission zones, residents may keep their cars from engine heat for a season at least.


5. ¿What alternatives are left?

vehicles ECO have a more favorable treatment in almost all parts. We refer to models that use gas (LPG or CNG), hybrids of any type and plug-in with autonomy reduced (40 km or less). For example, a gasoline Euro 4 converted to gas happens to be ECHO, with a better treatment that a Euro 6 diesel newly registered, that is C (label green).

For which a power is not in their interests now, the alternative to long-term more reasonable is the gas or hybrids of any type, preferably with a heat engine of gasoline. The prohibitions for driving to the vehicles ECO will take a pretty-in-reach, when the park electrical to be much more numerous.
