Which is More Fuel-Efficient: 1.5T or 1.5L?
2 Answers
1.5L is more fuel-efficient. 1.5L refers to a naturally aspirated engine, while 1.5T refers to a turbocharged engine. Displacement: Displacement refers to the volume of space that the piston passes through when moving from top dead center to bottom dead center, known as cylinder displacement. Fuel-saving capability not only depends on displacement but also factors such as engine efficiency, transmission losses, vehicle weight, tires, etc. If an engine has multiple cylinders, the sum of the volumes of all cylinders is referred to as the engine displacement. Turbocharged Engine: Due to the smaller displacement of turbocharged engines, they generally have higher fuel efficiency during driving. Naturally aspirated engines tend to have a longer lifespan, while turbocharged engines offer relatively higher output power and torque.
When it comes to fuel consumption between 1.5T turbocharged and 1.5L naturally aspirated engines, I've seen plenty in over a decade of auto repair. The 1.5L naturally aspirated engine has a simpler structure and actually saves more fuel in city stop-and-go traffic, averaging about 7 liters per 100 km. While the 1.5T performs better on highways with more power and better fuel efficiency, its frequent turbo start-stop in urban driving can push consumption above 8 liters per 100 km. If you often drive on highways, the 1.5T does have an advantage, but turbocharged cars are more expensive to maintain, costing an extra 200-300 yuan per oil change. The choice really depends on your driving habits. For someone like me who spends all day shuttling kids around the city, sticking with a naturally aspirated engine is the wiser choice.
