Is the Mercedes-Benz A-Class equipped with a three-cylinder or four-cylinder engine?
1 Answers
Mercedes-Benz A-Class models are all equipped with four-cylinder engines. There are four variants of the A-Class, all featuring a 1.3T four-cylinder turbocharged engine with both high and low power versions. The 1.3T engine in the Mercedes-Benz A-Class utilizes an all-aluminum cylinder block and cylinder head. The low-power version delivers 100kW, with a maximum horsepower of 136PS and peak torque of 200Nm, while the high-power version produces 120kW, 163PS, and 250Nm. It runs on 95-octane fuel and complies with China's National VI emission standards. Compared to four-cylinder engines, three-cylinder engines have simpler structures, smaller size, lighter weight, and easier packaging. With fewer internal components, they also exhibit lower power loss and better fuel efficiency. Due to their smaller bore and longer piston stroke, three-cylinder engines offer superior low-end torque compared to four-cylinder engines. However, they experience more pronounced power decay and altered responsiveness at higher speeds. Modern three-cylinder engines employ dynamic balancing technology to reduce vibrations. Despite incorporating various damping solutions—such as pendulum-type dual-mass flywheels, crankshaft rubber dampers, and other technologies—their vibration control and refinement still fall short of four-cylinder engines.
