The Peugeot 408, launched in 2010, represented Peugeot’s entry into the mid-size sedan segment, primarily aimed at markets outside of Europe where saloons remained popular. The first generation, designated the 408 I, was produced through 2014 and shared its platform with the Citroën C4 Picasso. Within the 408 I range, the 1.6-liter (117 hp) variant occupied the entry-level position, offering a balance of affordability and practicality. This model was particularly significant in regions where smaller displacement engines were favored due to tax regulations or fuel economy concerns. It served as a stepping stone for buyers into the Peugeot brand, offering a more accessible price point than the higher-powered options.

Powertrain & Engine Architecture
The heart of the 408 1.6 was the EC5F engine, a 1.6-liter inline-four cylinder petrol engine. This engine utilized a naturally aspirated configuration, relying on atmospheric pressure to draw air into the cylinders, rather than forced induction. It featured a double overhead camshaft (DOHC) valvetrain, operating four valves per cylinder, which contributed to improved breathing and efficiency. Fuel delivery was managed by a multi-port fuel injection system, providing precise fuel metering for optimal combustion. The engine produced 117 horsepower at 6000 rpm and 150 Nm (110.63 lb-ft) of torque at 4000 rpm. The engine’s compression ratio was set at 11:1. The 408 1.6 was typically paired with a five-speed manual transmission, although an older four-speed automatic transmission was also available in some markets. The automatic, while offering convenience, was known for its less-than-sporty shift characteristics and contributed to slightly lower fuel economy.
Driving Characteristics
The 1.6-liter engine in the 408 provided adequate, but not exhilarating, performance. Acceleration was modest, with a 0-60 mph time estimated around 11-12 seconds. The engine felt most comfortable in the mid-range, offering sufficient power for everyday driving situations like merging onto highways or overtaking slower traffic. Compared to the more powerful 2.0-liter variants, the 1.6 lacked the punch needed for spirited driving. The five-speed manual transmission offered a reasonable level of control, while the four-speed automatic resulted in noticeable gear hunting and a less engaging driving experience. The gear ratios were tuned for fuel efficiency rather than outright performance. The front-wheel-drive configuration provided predictable handling, but lacked the all-weather capability of all-wheel-drive systems found in some competing models.
Equipment & Trim Levels
The 1.6-liter 408 typically came with a base level of equipment, focusing on essential features. Standard amenities generally included air conditioning, power windows, central locking, and an audio system with MP3 compatibility. Safety features such as ABS (Anti-lock Braking System) and front airbags were also standard. Higher trim levels, available as options, added features like alloy wheels, a trip computer, rear parking sensors, and upgraded interior upholstery. Interior materials were generally durable but not luxurious, reflecting the car’s entry-level positioning. Dashboard design was functional and straightforward, prioritizing ease of use over aesthetic flair.
Chassis & Braking
The 408 I utilized a conventional MacPherson strut front suspension and a torsion beam rear suspension. This setup provided a comfortable ride quality, absorbing bumps and imperfections in the road surface effectively. The torsion beam rear suspension, while cost-effective, was not as sophisticated as independent rear suspension systems found in some competitors. Braking duties were handled by ventilated discs at the front and solid discs at the rear. ABS was standard, providing enhanced braking control in emergency situations. The 16-inch wheels, typically fitted with 215/55 R16 tires, offered a good balance of ride comfort and handling.
Market Reception & Comparison
The Peugeot 408 1.6 received mixed reviews. Critics generally praised its fuel efficiency and comfortable ride, but noted its lack of performance compared to rivals. The automatic transmission was often criticized for its sluggishness. Compared to other engines in the 408 lineup, such as the 2.0-liter petrol, the 1.6 offered significantly lower running costs but at the expense of driving enjoyment. The 1.6 was often seen as a sensible choice for budget-conscious buyers prioritizing practicality and fuel economy over performance. Competitors in the same segment included the Renault Fluence, Ford Focus, and Toyota Corolla.
Legacy
The Peugeot 408 1.6, while not a performance icon, proved to be a reliable and economical option for many buyers. The EC5F engine, when properly maintained, is known for its durability. On the used car market, these models are generally affordable and represent a good value proposition for those seeking a practical and fuel-efficient sedan. However, potential buyers should be aware of the limitations of the four-speed automatic transmission and ensure that the vehicle has been regularly serviced. The 408 I, in general, helped Peugeot establish a presence in markets where sedans remained popular, paving the way for future models.
