According to the data provided by the Ministry of Industry and Information Technology, the comprehensive fuel consumption of the Corolla 1.2t automatic transmission is 5.4L, the urban fuel consumption is 6.4L, and the suburban fuel consumption is 4.8L; while the comprehensive fuel consumption of the Corolla 1.2t manual transmission is 5.7L, the urban fuel consumption is 7L, and the suburban fuel consumption is 4.9L. Here are the related introductions: 1. Fuel consumption test by the Ministry of Industry and Information Technology: The fuel consumption test by the Ministry of Industry and Information Technology is based on the carbon balance principle, which calculates the fuel consumption by measuring the exhaust flow value and the concentration of carbon-containing gases through the principle of element conservation. Although the carbon balance method is an indirect calculation, it only requires connecting the instrument pipeline to the exhaust pipe for testing and has a high accuracy rate. Therefore, the carbon balance method is currently the mainstream testing method. 2. Power of the Corolla: The 1.2-liter turbocharged engine of the Toyota Corolla has the model code 9AR-FTS. This engine has a maximum power of 85kw, a maximum torque of 185 Nm, a maximum power speed of 5200 to 5600 rpm, and a maximum torque speed of 1500 to 4000 rpm.

I've been driving this Corolla for three years, mainly for commuting. The urban fuel consumption is around 7.5L/100km, while it drops to 5.8L/100km on highways. A friend borrowed it for a suburban trip recently and surprisingly achieved a low of 5.3L/100km. Using AC in summer increases consumption by about 0.8L, and cold starts in winter also result in higher fuel usage. The key factor is driving habits – I've experimented with gentle acceleration and anticipating traffic lights, which saves nearly 1L/100km compared to abrupt stops and starts. With a 50-liter fuel tank, a full tank gives about 650km range. The hybrid version is more economical – a colleague's hybrid Corolla averages just 4.9L/100km combined, but the price difference would take 70,000-80,000km to break even. Regular air filter changes and proper tire pressure maintenance can yield significant long-term savings.

The fuel consumption of the Corolla depends on the specific version. My 1.2T gasoline version averages 7-8L/100km in urban areas, while the 1.8L hybrid version can go as low as 4.5L. The powertrain design is quite smart—the CVT transmission keeps the engine RPM in the efficient range, and the start-stop system saves about 10% fuel when idling at traffic lights. During my last maintenance at the dealership, the technician mentioned that worn spark plugs and deteriorated engine oil can increase fuel consumption by around 0.5L. In real-world tests, fuel consumption rises noticeably when fully loaded with five people, especially on uphill sections. Fuel quality also has an impact, with the actual difference between 92 and 95 octane being less than 0.3L. After switching to low rolling resistance tires, my highway fuel consumption dropped from 6.1L to 5.7L.

There are three tips to save fuel with a Corolla: First, avoid flooring the accelerator—the characteristics of the CVT transmission mean smooth acceleration is most efficient. Second, use cruise control on highways for more stable speed than manual control. Third, set the air conditioning temperature above 24°C with the fan at the second speed for optimal economy. Over six months of tracking, gentle driving saved 1.2 liters compared to sport mode. The hybrid version excels in traffic, as the electric motor consumes almost no fuel. For the gasoline model, clean the throttle every 30,000 km—carbon buildup can inexplicably increase fuel consumption by 0.5 liters.
