Not all engines are equal - or at least, they come in different shapes and sizes, and, as a result, all of these have different capabilities and various applications. For example, a standard inline engine is very different from a rotary engine configuration, not just in design and structure, but also in advantages and disadvantages. While the former is simplistic in design and suitable for most mainstream cars, the latter offers immense power relative to its size and is more suited to sports cars.
