Which is more fuel-efficient, a car with a 't' or without a 't'?

[LeKai]

Vehicles without a 't' are more fuel-efficient. The 't' indicates that the car's engine is equipped with a turbocharger. The differences between vehicles with a 't' and without a 't' are as follows: Fuel Consumption: Compared to engines of the same displacement, model, and structure, engines with a turbocharger (with a 't') consume slightly more fuel. Power: Engines with a 't' have significantly higher output power than engines of the same displacement; thus, they have the highest power per liter. Torque: Under the same displacement conditions, turbocharged engines can greatly increase power and torque. For example, a 1.8T engine can be equivalent to a 2.4L engine, with more efficient fuel combustion.
