As an eco-thinking car fan, I’m interested in whether it’s a test on the environmental compatibility of hybrid cars and natural gas cars. In the discussions, only gasoline cars/diesel are always compared with hybrid cars. I assume that hybrid cars are better for the environment. I came up with the idea to inform myself about natural gas cars. They also seem to be more environmentally friendly than gasoline cars/diesel. By chance, one of you knows how it is compared between the two cars. or if you can buy hydrogen cars! If I like to buy a car later, it should become one of the most environmentally friendly cars, which is possible at the moment!
