The Cruze does not use a three-cylinder engine; both of its engine options are four-cylinder. The Cruze was equipped with a 1.4-liter four-cylinder turbocharged engine and a 1.5-liter four-cylinder naturally aspirated engine. However, the Cruze has been discontinued, with the latest model being the 2018 version before production ceased. More details are as follows: 1. As global environmental pollution issues become increasingly severe, countries worldwide are implementing stricter emission standards. Major automakers are actively seeking methods to reduce engine exhaust emissions, and three-cylinder engines are one of the solutions. 2. Three-cylinder engines are lighter, more fuel-efficient, and produce fewer emissions compared to four-cylinder engines. A three-cylinder engine has one less piston, connecting rod, ignition coil, spark plug, intake manifold, exhaust manifold, fuel injector, and set of valves than a four-cylinder engine. 3. The weight of a three-cylinder engine is an advantage, and its compact size is another benefit. Many automakers are adopting three-cylinder turbocharged engines, as turbocharging technology helps these engines deliver sufficient power for daily use. 4. However, three-cylinder engines also have drawbacks. Due to their inherent design, they are less smooth in operation compared to four-cylinder engines, and they tend to produce more vibration and noise.
