The Peugeot 308 III, launched in 2021 (Phase I), represents the third generation of Peugeot’s popular compact hatchback. Positioned within the highly competitive C-segment, the 308 aims to deliver a blend of style, technology, and efficiency. This iteration marked a significant departure from its predecessors, featuring a redesigned exterior, a completely new interior focused on i-Cockpit technology, and the introduction of electrified powertrain options. The model detailed here is the 1.2-liter (136 horsepower) Mild Hybrid e-DCS variant, a key offering in Peugeot’s strategy to broaden its appeal with fuel-efficient and lower-emission vehicles. While the 308 has historically been a strong seller in Europe, it has had limited direct sales in the United States, making it a notable example of a European-market vehicle with increasingly global technological influences.
Peugeot 308 III (Phase I): A Detailed Overview
The third-generation 308 builds upon the success of previous models, offering a more refined and technologically advanced package. The Phase I models, produced from September 2023 to March 2025, introduced a new design language for Peugeot, characterized by a more assertive front end with a frameless grille and claw-like LED daytime running lights. The interior underwent a complete overhaul, adopting Peugeot’s i-Cockpit design philosophy, featuring a compact steering wheel, a raised instrument cluster, and a central touchscreen infotainment system. The 1.2-liter Mild Hybrid e-DCS version specifically targets drivers seeking improved fuel economy and reduced emissions without the full commitment of a plug-in hybrid or fully electric vehicle.
Engine & Performance
The heart of the Peugeot 308 III 1.2 (136 Hp) Mild Hybrid e-DCS is a 1.2-liter, three-cylinder turbocharged gasoline engine (EB2LTD). This engine produces 136 horsepower at 5500 rpm and 230 Nm (169.64 lb-ft) of torque at 1750 rpm, offering a good balance of performance and efficiency. The “Mild Hybrid” designation indicates the presence of a 48-volt electrical system and a small electric motor, contributing an additional 21 horsepower and 51 Nm (37.62 lb-ft) of torque. This electric assistance primarily aids during acceleration and allows for smoother start-stop operation, improving fuel economy. The powertrain utilizes a six-speed automatic transmission (e-DCS) which is specifically tuned to work in conjunction with the mild hybrid system. Performance figures include a 0-100 km/h (0-62 mph) acceleration time of 9 seconds and a top speed electronically limited to 210 km/h (130.49 mph). The engine’s power-to-weight ratio is 10.1 kg/Hp, and the torque-to-weight ratio is 6 kg/Nm.
Design & Features
The Peugeot 308 III is a five-door hatchback, offering a practical and versatile body style. Its exterior design is characterized by sharp lines, a sloping roofline, and a modern aesthetic. The Phase I models feature distinctive LED headlights and taillights, contributing to a sophisticated appearance. Inside, the i-Cockpit design prioritizes driver engagement with its small, multi-functional steering wheel and elevated instrument panel. The central touchscreen infotainment system provides access to navigation, entertainment, and vehicle settings. Safety features are comprehensive, including ABS, electronic stability control, and a suite of driver-assistance systems. The 308 offers a comfortable and well-equipped interior, with a focus on quality materials and ergonomic design. Trunk space is a practical 412 liters (14.55 cu. ft.), expandable with the rear seats folded down.
