What is the difference between displacement with T and L?
2 Answers
T stands for Turbo, which refers to an engine equipped with a turbocharging device. L is the unit of volume, representing the displacement of the car engine, corresponding to a naturally aspirated engine. The following are the differences between displacement with T and L: 1. Working principle: The difference between these two engines lies in their working principles. Cars with the same displacement but with T have more power. If you prefer more powerful cars, you can choose those with T displacement, while L is generally sufficient for household use. 2. Fuel consumption: Since T-displacement engines require turbocharging, they need more fuel for the process. Therefore, cars with T displacement consume more fuel than those with L displacement, which is also a point to consider. 3. Failure rate: Due to the turbocharging in T-displacement cars, the wear and tear on the engine becomes more severe, leading to a higher failure rate compared to L-displacement cars.
I've been driving a 2.0T sedan for three years, and I can really feel the difference with turbocharged engines. When I step on the gas, there's a noticeable surge of power, especially when overtaking on the highway—it's effortless. However, there are clear downsides too, like needing to use higher-quality full synthetic oil, which makes maintenance more expensive compared to naturally aspirated engines. Once, during heavy traffic with frequent stop-and-go, the turbo kept engaging, and fuel consumption shot up way above the official figures. Naturally aspirated engines are smoother, with power delivered more evenly, making them more hassle-free for daily commuting. But with current policies favoring smaller engines, many 1.5T models have lower purchase taxes than 2.0L ones, which is a practical consideration.
