Speeding is not only dangerous for your safety and that of those around you, it also affects your pocket: the faster you go, the less it will take for the tank to empty. And we are not just talking about extreme speeds, even at legal speeds, such as 100 or 120 km/h, the changes are noticeable.
Keep in mind that although it seems like a small difference, those extra 20 km/h imply a change in consumption of between 0.5 and 1 l/100 kilometres. On a short journey it is a negligible amount, but if we are talking about a long trip, as is usual in summer trips, the result is not so negligible.
Let’s take as an example a trip of 1,000 kilometers, a distance that anyone can easily cover in the summer. In that case we are talking about between 5 and 10 liters of spent fuel in excess.
To continue with the hypothesis, let’s say that the vehicle is a diesel model, mechanics that give their best in terms of efficiency is on open roads and highways.
Bearing in mind that today, June 8, 2022, a liter of diesel is, on average, €1,984/l, how many euros per 1,000 km do you save on a diesel car if you go 100 km/h instead of 120 km/h? h?
In the event that the consumption of the car is more contained and applies the minimum, 0.5 l/100 km, we would speak of 5 liters less fuel on that route, which would mean a saving of 9.92 euros.
That would be in the event that the car only had a slight increase in spending, but, putting ourselves in the worst of situations, in which those extra 20 km/h meant an increase in consumption of 1l/100 km, we would talk about 10 extra litres, which would mean 19.84 euros that you could save just by slightly lifting your foot off the accelerator.
