Which is More Fuel-Efficient: Naturally Aspirated or Turbocharged?

[Ava]

Naturally aspirated engines are generally more fuel-efficient than turbocharged engines. Typically, the fuel consumption of a 1.8T turbocharged engine is equivalent to that of a naturally aspirated 2.0-2.4L model. The main reason is that turbocharging only increases pressure within the same cylinder volume to achieve better power and torque performance. With increased air pressure, gasoline consumption cannot be too low. Additional information: 1. A turbocharged engine refers to an engine equipped with a turbocharger. 2. A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then compresses the air delivered from the air filter pipe, pressurizing it before it enters the cylinder.
