Nowadays a lot of people travel by car, and their number  increaces rapidly. Cars pollute the atmosphere. The choice is ours whether we will continue to pollute the environment or not. New cars require large amounts of energy in their production process, as well as during their operation and it’s not easy but we should try to make cars as safe as possible for ecology of the planet. It will take long time before our streets will become silent, and environmentally clean. The engineers have designed a new internal combustion engine and it will continue to play an important role in the nearest 20-30 years. So what will be the car of the future? There are 2 options: 1) electric motor of small size and 2) hydrogen engine. There are already hundreds of electric cars in Moscow but they are a drop in an ocean. The cheapest way is to launch the production of hydrogen engines in the future.

I think it’s the most profitable means. In future, the driver will have a large number of electronic assistants. There won’t stay any mechanical parts.  In future electronics will play more important role in operating the car, than the driver. And in the distant future it may replace the man at operating the vehicle. The owner will only set the route, and the car itself will take him to places where it’s necessary. As for four-wheel cars, the cars won’t change. In 20-30-50 years they will be unchangeable. Well, I think we will see what the cars will be like in 50 years.
