Lately, start-stop systems have become more and more popular and are no longer  associated only with hybrids or luxury cars. This kind of system reflects the fuel consumption of a car.
Basically, when your car is idling, the entire engine shuts down, thus reducing emissions and improving fuel economy. It is an interesting feature that will fortunately be applied to many vehicles.
It is said that until 2016, the producers of  Chevrolet Malibu, Buick LaCrosse, Buick Regal, Kia Rio and BMW 5 Series will increase their sales up to 54%.
Little by little, we can all enjoy the modern technology that has managed to transform and ease our existence.
