After observing the various miniaturized engines from various companies, now we only have to draw conclusions about these engines and understand how they are built. What do we expect from these engines? But, more importantly, what is the future of this type of mechanics? The improvement of engines, especially gasoline ones, has experienced a significant increase in the last 15 years, and this is the topic I want to talk about in this video. In particular, the problems that these engines have and the responses developed by car brands to solve them. The goal is to continue to offer smoother and safer performance, but also to satisfy consumer demands. It is a complicated equation, which must meet both legislative norms and the economic aspirations of the brands. This conglomerate of interests has led to the shrinking of car engines, although there are exceptions that we will discuss in this video. Why do car brands decide to build such engines? We are talking about engines with a displacement of between 1.2 and 1.5 liters or even less than a liter. In recent years, there have been numerous examples on the market, and the main characteristic of these engines is the presence of a turbocharger, sometimes even two, which allows them to reach very high specific powers, sometimes exceeding 100 horsepower per liter of displacement.
