According to the official introduction from BMW Brilliance, the BMW 320li is equipped with a four-cylinder turbocharged engine, which has a displacement of 2.0 liters, a maximum horsepower of 184 hp, a maximum torque power of 135 kW, and a maximum torque of 300 N·m. The entire BMW 320li series uses a 2.0-liter four-cylinder turbocharged engine, paired with an 8-speed automatic transmission, and all models adopt a rear-wheel-drive configuration. Relevant information about the turbocharger is as follows: 1. Introduction: The turbocharger is essentially an air compressor that increases intake air volume by compressing air. 2. Working Principle: It utilizes the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber. The turbine, in turn, drives a coaxial impeller, which pressurizes air delivered through the air filter pipeline, forcing it into the cylinders. As the engine speed increases, the exhaust gas velocity and turbine speed also rise simultaneously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel. By correspondingly increasing the fuel quantity and adjusting the engine speed, the engine's output power can be enhanced.

As a long-time driving enthusiast, I've studied the BMW 320Li several times. Its displacement type is typically a 2.0-liter turbocharged gasoline engine, which is the standard configuration. In urban driving conditions, this displacement combined with turbocharging is quite practical, offering quick start-up response without being particularly fuel-consuming, and providing smooth acceleration during normal driving. BMW's design of this engine is very common in the 320Li series, for example, with an output power of over 180 horsepower and adequate torque, making highway overtaking not too strenuous. I've also noticed similar models like the Audi A4L, which also has a 2.0T version, but BMW's tuning leans towards sportiness, giving a more direct driving feel. If you're concerned about daily use, maintenance isn't troublesome; just regular checks of the engine oil and air filter are needed. Overall, the 2.0-liter turbocharged engine is a balanced choice for this type of extended sedan, satisfying both power needs and fuel efficiency.

I've driven my friend's BMW 320Li several times, equipped with a 2.0-liter turbocharged gasoline engine, and it felt fantastic. In city stop-and-go traffic, the car accelerates briskly from a standstill, and when the turbo kicks in, the push-back sensation is strong yet not overly aggressive. On the highway, I tested accelerating to 100km/h—it's powerful yet fuel-efficient, averaging around 7.5L/100km. The 2.0-liter design keeps engine noise low, ensuring good cabin quietness. Maintenance is straightforward; for example, regular oil changes can extend its lifespan, making it easier to care for compared to larger displacement engines. Considering environmental regulations, the 2.0-liter offers significant tax advantages, presenting high cost-effectiveness. Similar models like the Mercedes-Benz C-Class also use this displacement, but the BMW stands out with its sportier feel, making it ideal for driving enthusiasts like us.

I saw many discussions about the BMW 320Li on car forums. Its displacement type is mainly a 2.0-liter turbocharged engine, a standard that hasn't changed much over the years. Early 3 Series models used different displacements, such as the old 1.8-liter naturally aspirated engine, but now they've all been upgraded to turbocharging. The 2.0-liter design strikes a balance between environmental protection and performance, offering agile and responsive driving. BMW engineers have optimized this, ensuring reasonable power output and low maintenance costs. Compared to competitors like the Cadillac CT5, BMW's engine is durable and easy to repair. In summary, this configuration makes the 320Li both economical and practical.
