What is the difference between turbocharged and non-turbocharged engines?

[Lawson]

For vehicles with the same displacement, the differences between turbocharged and non-turbocharged engines are as follows: 1. The primary function of a turbocharger is to increase air intake, thereby enhancing the engine's power and torque, making the car more powerful. When an engine is equipped with a turbocharger, its maximum power can increase by 40% or more compared to when it is not equipped with one. 2. After turbocharging, the engine can generate greater power. At higher RPMs, the output power is improved. Generally, the characteristic is weak performance at low RPMs (except for models like Lancer and Volkswagen). When reaching a certain RPM, there is a sudden acceleration (this characteristic is not obvious in brands like Lancer and Volkswagen). At high RPMs, the performance is exceptionally strong (Lancer). Generally, choosing a small displacement engine with a turbocharger is more economical.

I've driven quite a few cars with both turbocharged and naturally aspirated engines, and the biggest difference I've noticed with turbocharging is the power boost. A small-displacement engine equipped with a turbo can instantly deliver horsepower comparable to a larger engine, making overtaking or climbing hills incredibly thrilling, especially on highways where it feels exhilarating. However, naturally aspirated engines respond more directly—step on the gas, and the power is immediately there, offering a smoother drive without any noticeable lag in traffic. That said, turbocharged engines do have a minor flaw called turbo lag, where there's about a half-second delay in power delivery when you lightly press the accelerator, which might be tricky for beginners to adapt to. Overall, the choice depends on your needs: go for turbo if you crave excitement and high-speed performance, or opt for naturally aspirated if you prioritize comfort and linear control. Nowadays, many cars use turbos for better fuel efficiency, though long-term maintenance can be slightly more expensive.
