What's the difference between 1.6L and 1.2T, which one has more horsepower?

The difference between 1.6L and 1.2T is the engine type: 1.6L is a naturally aspirated engine, while 1.2T is a turbocharged engine. The 1.2T engine has more horsepower. Naturally aspirated is a type of car intake that relies on atmospheric pressure to force air into the combustion chamber without any supercharger. Modern engines can be divided into naturally aspirated and supercharged types, with the latter further categorized into mechanical supercharging, turbocharging, and pressure wave supercharging. A turbocharged engine refers to an engine equipped with a turbocharger. A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial force of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then pressurizes the air delivered through the air filter pipe, forcing it into the cylinders.
I worked in an auto repair shop for several years and have dealt with both types of engines quite a bit. The 1.6L naturally aspirated engine is like a steady and reliable worker, delivering power smoothly with linear acceleration, but its maximum horsepower is usually around 120. The 1.2T, on the other hand, is impressive—thanks to the little helper called a turbocharger. Despite its smaller displacement, it can push horsepower beyond 130. When the turbo kicks in during overtaking, the extra punch is substantial. However, I should remind you that turbocharged engines are a bit more delicate. Maintenance costs are about 30% higher than naturally aspirated engines, and as they age, the turbo is prone to issues—replacing one can cost half as much as a new engine. If you frequently drive on highways, the 1.2T is indeed thrilling, but for pure city commuting, the hassle-free 1.6L is a better fit.
Last week I accompanied my buddy for a test drive, specifically comparing the 1.6L and 1.2T models. To be honest, the 1.6L felt smoother at startup, but once the RPM exceeded 2000, the 1.2T became as energetic as if it had been given a boost. Official data shows the 1.2T has about 15% more horsepower. The sales guy said a turbocharger is like putting a pressure mask on the engine, squeezing out an extra 20 horsepower from the same air intake. However, I noticed something interesting: small-displacement turbo cars show lower fuel consumption on the display, but in actual stop-and-go traffic with frequent turbo starts and stops, their fuel consumption ends up exceeding that of the 1.6L. My suggestion is to consider your driving scenario: if you often drive on suburban expressways, the 1.2T is more exhilarating and fuel-efficient; but if you're in a downtown area with dense traffic lights, the smoothness of a naturally aspirated engine is more comfortable.
Last year when I changed cars, I also struggled with this issue. After researching, I found that among mainstream models, 1.2T engines generally have 10-25 more horsepower than 1.6L engines. The principle is that the turbo reuses exhaust gases to drive intake pressure boosting. But in actual driving, the difference isn't as dramatic as the data suggests, especially at low speeds where the 1.6L responds quicker. I ultimately chose the 1.6L for its simple and reliable structure - my 8-year-old car hasn't even needed a throttle body cleaning. A friend who bought a 1.2T enjoys stronger acceleration, but spent over 3,000 yuan fixing turbo seal oil leaks at 60,000 km. If you want power, go turbocharged; for peace of mind, naturally aspirated is the way to go.
