The fuel consumption of Toyota Corolla varies.

It's influenced by multiple factors.

The engine's performance plays a crucial role.

The car's quality, driving resistance, and the type of transmission also matter.

Toyota has been making efforts to improve fuel efficiency.

For example, they use smaller-displacement engines like the 1.2T and have replaced some larger engines to lower fuel consumption.

The latest 1.5L engine in Corolla further reduces fuel consumption.

The official minimum fuel consumption of the 1.5L Corolla is 5.1L/100km, while that of the 1.2T is 5.6L/100km.

However, it should be noted that the actual fuel consumption might differ from the official figures and depends on various real-world driving conditions.

To enhance fuel economy, Toyota also considers factors such as reducing the car's weight, minimizing driving resistance, and optimizing the engine's working conditions.

Moreover, automotive industry regulations like the CAFC (Corporate Average Fuel Consumption) policy have pushed Toyota to continuously improve the fuel efficiency of its vehicles.

Overall, the fuel consumption of Toyota Corolla is relatively good, but specific figures can vary based on different driving scenarios and vehicle configurations.
