It is good that most car manufacturers have begun to pay attention to environmental safety features of their newly designed vehicles. In this regard the latest development was the concept of a hybrid car from Mercedes-Benz.
Mercedes-Benz B-Klasse, which served as the basis for the new Concept Blue Zero vehicles has immediately spawned three new models.
Mercedes Blue Zero E-Cell is a classic electric car with its own advantages and disadvantages, among which the short path range, which is only 200 km, although it should be noted that this disadvantage is common for most electric cars.

Another model of the same class, the Blue Zero E-Cell Plus is a hybrid, equipped with both electric and gasoline engines, which increase the distance run up to 600 km. The fuel consumption is very small, just 2.9 liters per hundred km, but this is another plus in favor of eco-friendliness.

The third option would be a model for fans of the hydrogen engine (400 km).
The cost of these cars is unknown, as these are still concept vehicles, but it will be clearly higher than that of gasoline counterparts.
