Throughout automotive history, numerous engineers were determined to think outside of the box and try something new. While most manufacturers used the standard 4, 6, or 8 cylinders engine configuration, some companies dared to try something different. This approach gave rise to one of the most unique engine configurations five cylinders. While it never became a mainstream solution, five-cylinder engines became quite popular due to their special performance and distinctive sound.

Five-cylinder engines became particularly popular over time since they offered several key characteristics that distinguished them from other engine setups. First of all, these engines offered better performance compared to most four-cylinder engines while being more compact and lighter than six-cylinder engines. But what really set these engines apart was their unique exhaust note. The odd number of cylinders meant that the firing order was irregular, thus creating a distinct deep warble sound.

The five-cylinder engines were used in a variety of cars including luxury sedans, rally monsters, and hot hatches. Some of these vehicles were focused primarily on reliability, while others prioritised performance. Altogether, these models demonstrate that thinking outside of the box can result in some very interesting and memorable cars.
