Ces dernières années, d’importantes exigences ont été posées à l’industrie automobile, mais les voitures ont continué de rouler grâce à des carburants de relativement faible qualité, et cela doit changer dans les quelques années à venir.
If you put that question to the motor industry, the answer you will get is that they are not of high quality, but rather deficient. Heavy demands have been made of the car industry over recent years, but it has always had to run cars on relatively low-quality fuels, and that is something that must change over the next few years.
