The Peugeot 308 SW III (Phase I, 2021) marks a compelling entry into the highly competitive European C-segment, specifically targeting the practical and family-oriented station wagon market. Launched in September 2021, this generation of the 308 SW, or Sport Wagon, builds upon Peugeot’s legacy of combining distinctive design with functional engineering. Positioned as a versatile vehicle, it caters to consumers seeking ample cargo space and passenger comfort without sacrificing driving dynamics or fuel efficiency. While not directly offered in the North American market, the 308 SW III exemplifies the sophisticated design and advanced powertrain technologies prevalent in modern European compact cars, presenting a compelling package for its primary audience until its production concluded in June 2022. This particular variant, equipped with the 1.2 PureTech (110 Hp) engine, highlights Peugeot’s commitment to optimizing performance and environmental responsibility through downsized, turbocharged gasoline units.
Engine and Performance of the Peugeot 308 SW III (Phase I, 2021)
At the heart of this iteration of the Peugeot 308 SW III is the highly acclaimed 1.2 PureTech (110 Hp) engine, a testament to modern internal combustion engine design focused on efficiency and responsive power delivery. This powerplant, designated HNP EB2ADT, is a compact 1.2-liter (1199 cm3 or 73.17 cu. in.) inline three-cylinder unit, configured for front, transverse mounting. Despite its modest displacement, the engine benefits significantly from turbocharging and an intercooler, allowing it to produce a respectable 110 horsepower at 5500 rpm. This power output, translating to 91.7 Hp per liter, demonstrates impressive specific power for a non-performance-oriented engine.
Equally critical to its dynamic character is the torque output. The 1.2 PureTech delivers a robust 151.2 lb.-ft. (205 Nm) of torque arriving at a remarkably low 1750 rpm. This early peak torque is a hallmark of modern turbocharged engines, providing excellent low-end responsiveness and reducing the need for frequent downshifts, thereby enhancing both driving pleasure and fuel efficiency. Power is transmitted to the front wheels via a precise 6-speed manual transmission, offering engaging control for the driver. The drivetrain architecture is a straightforward front-wheel-drive setup, which is typical for this segment and contributes to predictable handling characteristics.
Further enhancing its performance and environmental credentials, the engine incorporates several advanced technologies. Direct fuel injection ensures precise fuel delivery for optimal combustion, while a DOHC (Double Overhead Camshaft) valvetrain with four valves per cylinder maximizes airflow. The compression ratio of 10.5:1 is well-suited for a turbocharged gasoline engine, balancing power and efficiency. In line with contemporary environmental standards, the 1.2 PureTech engine is equipped with a Start & Stop System, which automatically shuts off the engine when the vehicle is stationary, reducing fuel consumption and emissions in urban environments. Furthermore, a particulate filter is integrated into the exhaust system, ensuring compliance with the stringent Euro 6.3 emission standard, a crucial requirement for vehicles sold in the European Union. With a curb weight of 2866.01 lbs (1300 kg), the vehicle achieves a weight-to-power ratio of 11.8 kg/Hp and a weight-to-torque ratio of 6.3 kg/Nm, indicating a well-balanced power-to-weight profile for everyday driving.
Design and Features
The Peugeot 308 SW III (Phase I, 2021) distinguishes itself with a sleek and modern station wagon body type, a design choice that prioritizes both aesthetics and practicality. Measuring 182.52 inches (4636 mm) in length, 72.91 inches (1852 mm) in width (extending to 81.18 inches or 2062 mm including mirrors), and 56.85 inches (1444 mm) in height, the 308 SW presents a well-proportioned and dynamic stance. Its extended wheelbase of 107.56 inches (2732 mm) contributes significantly to improved ride comfort and enhanced interior space, particularly for rear passengers.
The exterior design is characterized by Peugeot’s contemporary styling language, featuring sharp lines, a bold front fascia, and distinctive LED lighting signatures (though specific lighting technology isn’t detailed, it’s characteristic of modern Peugeots). The aerodynamic profile is underscored by an impressive drag coefficient (Cd) of 0.277, which not only contributes to its visual appeal but also plays a crucial role in optimizing fuel efficiency and reducing wind noise at higher speeds. The design ensures a practical yet stylish vehicle, appealing to families and individuals who require substantial cargo capacity without compromising on sophisticated aesthetics.
Inside, the 308 SW III offers seating for five occupants across five doors, providing easy access to both front and rear seats. The station wagon body truly shines in terms of cargo versatility. It boasts a minimum trunk space of 21.47 cu. ft. (608 liters), which is highly competitive within its segment, making it ideal for daily errands, groceries, or luggage for weekend trips. When the rear seats are folded, this capacity expands dramatically to a cavernous 57.7 cu. ft. (1634 liters), transforming the vehicle into a highly capable hauler for larger items. The fuel tank capacity of 13.74 US gallons (52 liters) ensures a decent cruising range, a practical consideration for long-distance travel.
Beyond its spacious interior, the 308 SW III incorporates essential modern features for safety and convenience. Standard assisting systems include ABS (Anti-lock Braking System), a fundamental safety feature designed to prevent wheel lock-up during hard braking. The steering system utilizes an electric power steering rack and pinion setup, offering precise control and ease of maneuverability, particularly in urban environments, further aided by a minimum turning circle of 35.04 feet (10.68 meters). The vehicle comes with tire options of 205/55 R16 or 225/45 R17, providing a balance between ride comfort and road holding. With a ground clearance of 5.71 inches (145 mm), it is well-suited for typical road conditions, while its overall design and feature set underscore its position as a practical, efficient, and well-equipped family vehicle for the European market.
