408's 1.2T engine is a three-cylinder, but not all models of the Peugeot 408 are equipped with three-cylinder engines. The Peugeot 408 uses two types of engines in total: one is a 1.2-liter turbocharged engine, and the other is a 1.6-liter turbocharged engine. The Peugeot 408 is a compact car under the Peugeot brand, with a wheelbase of 2730 mm, and dimensions of 4750 mm in length, 1820 mm in width, and 1488 mm in height. The front suspension of the Peugeot 408 uses a MacPherson independent suspension, while the rear suspension employs a torsion beam non-independent suspension. French cars tend to favor torsion beam suspensions due to their compact size and minimal space occupation. Using a torsion beam suspension for the rear can expand the rear seating space and trunk space.

















I've driven several 408s before, one of which was the three-cylinder version, specifically the 1.2L PureTech turbocharged gasoline engine model. This engine is quite popular, especially in the European and Chinese markets. Its power output is sufficient for daily use, but there's a slight vibration at startup—once it's running, it smooths out. The fuel consumption is impressively low, staying under 6L per 100km, which is a big plus for fuel efficiency. However, if you're fully loaded and driving on mountain roads, you might feel it lacks a bit of power. Remember, not all 408s come with a three-cylinder engine—some top-end or older models are equipped with a 1.6L four-cylinder engine, which offers more horsepower but slightly higher fuel consumption. The newly launched hybrid version is also worth considering. When choosing a car, make sure to check the year and spec sheet to avoid any confusion.

I usually enjoy researching compact cars, and the 408 is one of the models I frequently look into. Its engine lineup indeed includes a 1.2T three-cylinder turbocharged gasoline engine option. This small-displacement design is quite trendy, delivering around 130 horsepower, offering quick starts and environmental friendliness, making it a top choice for many young car owners. However, don't overlook other configurations: the 408 also comes with a 1.6-liter four-cylinder version, which provides more aggressive acceleration, suitable for those who want a bit more performance. Price-wise, the three-cylinder version is usually cheaper, and later modifications like upgrading the intake system can enhance the experience. I recommend test-driving both before purchasing to feel the differences in engine vibration and noise. Personally, I think the three-cylinder version is quite practical for city driving.

From my understanding of automotive technology, the 408 offers three-cylinder engines in different models, primarily the 1.2-liter turbocharged PureTech gasoline engine. This little powerhouse features an aluminum alloy cylinder block for weight reduction, optimized fuel injection, and delivers approximately 100 kW of horsepower, paired with a responsive six-speed automatic transmission. It has excellent emission control, meeting environmental standards, and vibrations are minimized with a balance shaft. In real-world driving, the initial acceleration might feel slightly weak, but high-speed performance is stable. It's worth noting that the 408 also comes with four-cylinder engines like the 1.6-liter model, which offers more robust power output. Recommendation based on driving needs: the three-cylinder is ideal for economical purposes.

As a family user, I chose the 408 for its engine's fuel efficiency. Yes, my car is the 1.2T three-cylinder version, and fuel economy is key, with a consumption of 6-7 liters per 100 kilometers, making it quite economical for school runs. Maintenance is simple, and replacing filters isn't expensive, but there was noticeable vibration when new, requiring regular servicing to prevent wear. The power is sufficient for carrying people and cargo, and it handles uphill drives without strain. Three-cylinder engines are common in local mainstream configurations, though some regions offer four-cylinder or diesel alternatives. Consider daily road conditions and load capacity when choosing a car.

Comprehensive analysis of the 408's engine situation: It indeed offers models equipped with three-cylinder engines, such as the 1.2L turbocharged gasoline variant, known for its high efficiency and low carbon emissions, widely used in the compact car market. Meanwhile, four-cylinder engines like the 1.6L gasoline engine provide stronger dynamic performance. When purchasing, it's advisable to check the manufacturer's configurations: the three-cylinder version is budget-friendly with low fuel consumption, ideal for daily commuting; the four-cylinder version offers ample horsepower, suitable for long-distance travel or carrying more passengers. Options vary by year and sales region, and test driving can verify the vibration control level.
