408 is turbocharged, equipped with two types of engines: a 1.2-liter turbocharged engine and a 1.6-liter turbocharged engine. The 1.2-liter turbocharged engine is a three-cylinder engine, while the 1.6-liter turbocharged engine is a four-cylinder engine. The 1.2-liter turbocharged engine in the Peugeot 408 has a maximum power of 100 kW and a maximum torque of 230 Nm, paired with a 6-speed dual-clutch transmission. The 1.6-liter turbocharged engine delivers a maximum power of 125 kW and a maximum torque of 250 Nm, matched with a 6-speed automatic transmission. The dimensions of the Peugeot 408 are 4750mm in length, 1820mm in width, and 1488mm in height, with a wheelbase of 2730mm.

The 408 does indeed have turbocharged models. I discussed this with fellow car enthusiasts at a meetup. The current new models particularly feature the popular 1.2L PureTech three-cylinder turbocharged engine, which delivers strong power in the 408, with quick acceleration from a standstill, making overtaking effortless. Compared to the older naturally aspirated versions, it also offers better fuel efficiency, especially on highways. However, specifics depend on the year and market—for instance, many models sold in China after 2015 came with turbocharging. When buying used or base models, you might still encounter naturally aspirated versions, but the mainstream recommendation is to opt for the turbo variant for a more spirited drive. Maintenance-wise, turbocharged engines require regular checks on engine oil and air filters to prevent clogging or overheating, but overall reliability is decent. Personally, I really enjoy this engine setup—it enhances the driving experience.

I remember when I first got into cars over a decade ago, the 408 mainly came with naturally aspirated engines, which felt smooth but lacked power. Things have changed now – many new models have introduced turbocharging, like the 1.6L THP turbocharged engine, making acceleration much smoother. This shift is to meet emission standards and improve efficiency, plus it's more fuel-friendly for city driving. To distinguish between trims, entry-level models might still use naturally aspirated engines, while higher trims are mostly turbocharged. It's worth test-driving to feel the turbo kick-in moment – the sound is quite distinctive but not too loud. Also, turbocharged engines might have a bit of lag at low speeds, which takes some getting used to. Checking official specs or dealer info before buying is always a good idea to avoid confusion.

As an ordinary car owner, I've noticed that the 408 comes with two types of engines, with turbocharged ones being quite common, especially in most new models after 2018. The advantage of using a turbocharged engine is the improved power and some fuel savings during daily commutes, though the initial price is slightly higher. When purchasing, you need to check the specific model - the 1.2L turbo version responds quickly in city driving and is suitable for family use. Occasionally, I hear that maintaining the turbo system requires a bit more effort, but don't worry too much about complexity; just follow the regular service schedule. Compared to naturally aspirated engines, it's more environmentally friendly and delivers smoother driving, making it a worthy choice.

From a technical perspective, the 408 offers turbocharged options that utilize exhaust gas boosting to enhance engine performance. In simple terms, exhaust airflow drives the turbine blades, accelerating air intake to unleash more horsepower. The 408 commonly features turbocharged three-cylinder engines like the 1.2L PureTech, which are compact in design yet highly efficient in output. Compared to naturally aspirated engines, it delivers robust torque at low RPMs, making driving more agile. However, the engine noise is slightly louder, which may affect the quietness experience. It's recommended to verify the model specifications when making a selection to avoid misunderstandings.

The 408's engine configurations vary across different markets. Models sold in China typically include turbocharged engines, such as the 1.6THP turbocharged power unit, which enhances overall efficiency. However, in some parts of Europe, there are also hybrid or non-turbo base versions. Turbocharging offers a balance between economy and power, with quick starts and reduced fuel consumption. For reference, the differences between the 2010 and 2020 models are significant. Before purchasing, check local inventory to ensure it matches your preferences.
