What is the difference between 1.8L and 1.8T?
2 Answers
1.8T and 1.8L both refer to an engine displacement of 1.8 liters, where the 'T' indicates that the engine is turbocharged. Therefore, 1.8T means a 1.8-liter turbocharged engine, while 1.8L simply denotes a 1.8-liter naturally aspirated engine without turbocharging. Here is some information about turbocharging: 1. The primary function of a turbocharger is to increase the engine's air intake, thereby enhancing its power and torque output, making the car more powerful. 2. When a turbocharger is installed on an engine, its maximum power output can increase by 40% or more compared to the same engine without a turbocharger. This means that the same engine can generate greater power after being turbocharged. 3. Taking the most common 1.8T turbocharged engine as an example, after turbocharging, its power output can reach the level of a 2.4L engine, but its fuel consumption is not significantly higher than that of a 1.8L engine. In another sense, this improves fuel economy and reduces exhaust emissions.
I just drove a car with a 1.8L naturally aspirated engine, and it felt smooth and worry-free during acceleration. Without a turbocharger, the engine relies on natural aspiration, so the horsepower is relatively lower, but the driving is very linear—power builds up gradually when you step on the gas, making it suitable for daily commutes and city driving. The fuel consumption is also quite stable, averaging around 8-10 liters per 100 kilometers. Maintenance is cheaper because the simpler structure lacks turbo components, reducing the likelihood of breakdowns—just an oil change will do. Overall, the 1.8L engine is economical, affordable, and reliable.
