Which Peugeot 408 Version Should You Buy?
The Peugeot 408 choice depends chiefly on whether you want the efficiency of the earlier Sedan, the performance of its turbocharged gasoline engine, or the newer SUV Coupe with an Automatic transmission throughout the range. The first generation ran from 2010 to 2017 with 7 versions, followed by a 2017–2022 restyling with 4 versions.
The Peugeot 408 choice depends chiefly on whether you want the efficiency of the earlier Sedan, the performance of its turbocharged gasoline engine, or the newer SUV Coupe with an Automatic transmission throughout the range. The first generation ran from 2010 to 2017 with 7 versions, followed by a 2017–2022 restyling with 4 versions. The second generation began in 2023 as an SUV Coupe with 3 versions. Across the catalogue, every version is FWD, but outputs span 110–225 hp, transmissions range from 4 to 8 gears, and the available powertrains include Gasoline, Diesel, and Plug-in configurations.
Peugeot 408 generations compared
The first-generation Peugeot 408 was a Sedan produced from 2010 to 2017. Its 7 versions provided the widest choice: naturally aspirated Gasoline engines, turbocharged Diesel engines, a turbocharged Gasoline engine, Manual and Automatic gearboxes, and outputs from 110 to 150 hp. The 2017–2022 restyling remained part of this generation and retained the Sedan body. Its 4 versions narrowed the range to 114–150 hp, standardized the gearbox at 6 gears, and reduced ground clearance from 178 to 175 mm.
The second-generation Peugeot 408 has been produced since 2023 as an SUV Coupe. Its 3 versions comprise a 130 hp Gasoline 1.2 AT and two Plug-in 1.6 AT versions producing 180 and 225 hp. All use an 8-speed Automatic and FWD. The suspension also changed from the earlier Independent, spring front and Semi-independent, spring rear arrangement to Independent, spring suspension at both ends.
Peugeot 408 engine specs and version comparison
Repeated names are distinguished below by power and production period. Displacement is shown exactly in cubic centimetres because that reveals differences hidden by the rounded version names.

Among versions with measured torque, the 2017–2022 1.6 HDi MT leads with 270 Nm, which is 30 Nm more than either 150 hp turbocharged Gasoline version. Its peak torque also arrives at 1750 rpm, while the 150 hp Gasoline engines reach 240 Nm at 1400 rpm. The 2010–2017 Diesel alternatives produce 254 Nm at 1750 rpm.
Calculated from the listed displacement and output, the 2010–2017 and 2017–2022 150 hp, 1598 cc engines each deliver about 93.9 hp per litre. The since-2023 1.2 AT produces about 108.4 hp per litre, while the Plug-in 1.6 AT versions produce 112.5 and 140.6 hp per litre respectively. Because torque is not measured for the Plug-in versions, their pulling performance cannot be compared numerically here.

For acceleration, the 2017–2022 1.6 THP AT with 150 hp is the strongest measured choice: its 8.1-second result is 1.5 seconds quicker than the earlier 150 hp 1.6 AT. It also reaches 208 km/h while using 6.7 L/100 km combined, a reduction of 1.5 L/100 km from the earlier turbo version’s 8.2 L/100 km. Its CO₂ figure is 151 g/km, 39 g/km lower.
For minimum measured fuel use, choose the 2017–2022 1.6 HDi MT. Its 4.9 L/100 km combined result is 1.8 L/100 km below the 150 hp 1.6 THP AT from the same period, although it takes 3.5 seconds longer to reach 100 km/h. The earlier 112 hp Diesel records 5.0 L/100 km combined, only 0.1 L/100 km more.
The since-2023 1.2 AT combines the highest measured top speed, 210 km/h, with 6.1 L/100 km combined consumption. Acceleration is 11.5 seconds. Performance and consumption for both Plug-in 1.6 AT versions are not measured, so output alone cannot establish which is quicker or more economical.

The best calculated kerb-weight-to-power ratio among versions with measured weight is 9.37 kg per hp for the 2017–2022 1.6 THP AT with 150 hp. The earlier 150 hp 1.6 AT is close at 9.47 kg per hp. The since-2023 1.2 AT carries 11.28 kg per hp. Weight is not measured for the 180 hp and 225 hp Plug-in versions, preventing the same comparison.
Which Peugeot 408 version to choose and why
For the best balance of measured acceleration and economy, the 2017–2022 1.6 THP AT with 150 hp is the standout. It combines an 8.1-second 0–100 km/h time, a 208 km/h maximum, 6.7 L/100 km combined consumption, and the best measured weight-to-power ratio in the range.
For fuel economy and torque, the 2017–2022 1.6 HDi MT with 114 hp is the stronger fit. It delivers the catalogue’s highest measured torque at 270 Nm and its lowest combined consumption at 4.9 L/100 km. The trade-off is an 11.6-second acceleration time and a Manual gearbox.
For a naturally aspirated first-generation car, the 2010–2017 1.6 MT with 120 hp offers the most persuasive measured combination. Compared with the 120 hp 1.6 AT, it reaches 100 km/h 2.9 seconds sooner, has a top speed 10 km/h higher, and consumes 0.7 L/100 km less combined. The Automatic alternative exchanges those results for a 4-speed Automatic.
For the second-generation SUV Coupe, the 1.2 AT with 130 hp is the version that can be assessed most completely: it has a measured 230 Nm, 11.5-second acceleration, 210 km/h top speed, 6.1 L/100 km combined consumption, and 1467 kg kerb weight. The Plug-in 1.6 AT versions provide 50 hp and 95 hp more respectively, but their torque, performance, economy, weight, tank capacity, clearance, and wheel sizes are not measured. Choose between the 180 hp and 225 hp Plug-in versions on the stated output only if that difference is decisive; the supplied data does not support broader claims about their speed, efficiency, price, or practicality.
No Peugeot 408 price or GT-specific information is present in the catalogue data. Consequently, neither purchase price nor “what the extra money buys” can be calculated, and reliability, engine faults, oil specification, oil capacity, engine-number location, interior equipment, and trunk capacity are also not measured.
