The history of the four-cylinder engine dates back to the early days of the automotive industry. These engines were massive, often eclipsing the displacement sizes we see today. While they have become more efficient and smaller over time, there have been instances of large four-cylinder engines. One notable example is the Mitsubishi 3.2-liter turbodiesel, which was used in the Pajero SUV and produced 197 horsepower and 325 lb-ft of torque. Another large four-cylinder engine is the Pontiac Trophy 4, which had a 3.2-liter displacement and produced 166 horsepower and 215 lb-ft of torque.
In contrast, the future of the four-cylinder engine is uncertain, as the trend is towards electrification. While there may be a place for large four-cylinder engines in sports cars or racing, they are likely to be replaced by smaller engines in small cars. The Mitsubishi 3.2-liter turbodiesel is an exception, but it is primarily used in commercial vehicles. Overall, the four-cylinder engine has played a significant role in the history of the automotive industry, and its impact is still felt today.
