Which is more fuel-efficient, 1.8T or 1.8L?

[VanLilliana]

1.8L is more fuel-efficient than 1.8T. More information about 1.8L and 1.8T is as follows: 1. The 1.8T is a turbocharged engine, while the 1.8L is a naturally aspirated engine. For the same model and displacement, the turbocharged version delivers stronger power but consumes more fuel. 2. At low speeds, the 1.8T performs similarly to a regular 1.8 engine, but the turbo engagement actually increases fuel consumption. However, at high speeds, the turbocharged engine provides more power and higher output compared to the 1.8L engine, resulting in increased fuel consumption.
