Powertrain and Performance of the Peugeot 308 SW III (Phase I, 2021)

At the heart of the Peugeot 308 SW III (Phase I, 2021) 1.6 (180 Hp) Plug-in Hybrid e-EAT8 lies a highly integrated and efficient powertrain architecture. This PHEV system combines a 1.6-liter turbocharged inline-four petrol engine with an electric motor, strategically placed between the combustion engine and the transmission. The internal combustion engine (ICE), identified by the code DGX EP6FADTXHPE, boasts a displacement of 1598 cubic centimeters (97.52 cu. in.) and produces a respectable 150 horsepower at 6000 rpm, alongside 184.39 lb.-ft. of torque at a low 1750 rpm. This engine features direct injection, a turbocharger, an intercooler, and a DOHC valvetrain, ensuring optimal power delivery and efficiency while meeting the stringent Euro 6d emission standard, further enhanced by a particulate filter.

Complementing the petrol engine is a potent electric motor, contributing an additional 110 horsepower at 2500 rpm and a substantial 236.02 lb.-ft. of torque across a broad range from 500 to 2500 rpm. Together, this hybrid setup delivers a combined system output of 180 horsepower and an impressive 265.52 lb.-ft. of torque. This substantial torque is crucial for responsive acceleration and flexible driving dynamics. Power is channeled to the front wheels through an advanced 8-speed automatic e-EAT transmission, designed for smooth and efficient gear changes. The Drivetrain Architecture allows for seamless transitions between full electric, hybrid, and internal combustion modes, providing versatility for various driving conditions.

Performance figures for the 308 SW III PHEV are noteworthy for a family-oriented station wagon. It accelerates from 0 to 60 mph in an estimated 7.3 seconds, with 0 to 100 km/h achieved in 7.7 seconds. The maximum speed is rated at 139.81 mph (225 km/h), while in pure electric mode, the vehicle can reach speeds of up to 83.89 mph (135 km/h). These figures underscore the vehicle’s capability to offer both spirited driving and relaxed cruising. The weight-to-power ratio stands at 9.2 kg/Hp (108.5 Hp/tonne), and the weight-to-torque ratio is 4.6 kg/Nm (217 Nm/tonne), indicating a well-balanced power-to-weight characteristic for its segment.

One of the most compelling aspects of this PHEV is its exceptional fuel economy and electric range. The 12.4 kWh gross lithium-ion battery, conveniently located under the rear seats, provides an all-electric range of 39.77 to 42.25 miles (64-68 km) according to the WLTP cycle. This allows for significant daily commutes to be completed entirely on electric power, drastically reducing fuel consumption and emissions. Combined fuel consumption (WLTP) is an outstanding 1.1-1.2 liters per 100 km, translating to an estimated 213.8 – 196 US mpg. The CO2 emissions are remarkably low, ranging from 25-27 g/km (WLTP), highlighting its environmental credentials. Average energy consumption (WLTP) is reported between 14.8-15.2 kWh/100 km, or approximately 141-138 MPGe. These figures position the Peugeot 308 SW III PHEV as one of the most efficient vehicles in its class, offering substantial savings on running costs and a reduced carbon footprint.

Design and Features

The Peugeot 308 SW III (Phase I, 2021) distinguishes itself with a modern and assertive design language that embodies Peugeot’s contemporary aesthetic. As a station wagon (or estate), it prioritizes both style and practicality, offering a spacious and versatile interior within a sleek exterior. The vehicle measures 182.52 inches (4636 mm) in length, 72.91 inches (1852 mm) in width (excluding mirrors), and 56.85 inches (1444 mm) in height, with a wheelbase of 107.56 inches (2732 mm). These dimensions contribute to a balanced stance and a commanding road presence, while the low drag coefficient of 0.277 enhances aerodynamic efficiency.

The body features five doors and accommodates five occupants comfortably, making it an ideal choice for families. The design incorporates sharp lines, a bold front grille, and signature LED lighting (typical for modern Peugeot vehicles, though not explicitly detailed in the provided data) that give it a distinctive appearance. Inside, the focus is on ergonomic design and advanced technology. While specific interior features beyond seating capacity are not detailed, modern Peugeot vehicles typically feature the i-Cockpit, a unique driver-oriented layout with a small steering wheel, a head-up digital instrument cluster, and a central touchscreen infotainment system, all designed to enhance the driving experience and connectivity.

Practicality is a cornerstone of the station wagon body type, and the 308 SW III excels in this regard. It offers a generous trunk (boot) space of 19.35 cubic feet (548 liters) with the rear seats in place, expanding to an impressive 55.59 cubic feet (1574 liters) when the rear seats are folded down. This ample cargo volume ensures that the vehicle can easily accommodate luggage, groceries, or larger items for various lifestyle needs. The maximum load capacity is 1126.56 lbs (511 kg), and it boasts a permitted trailer load with brakes of 3196.7 lbs (1450 kg), further enhancing its utility.

Safety and driving dynamics are also key considerations. The vehicle is equipped with a robust suspension system, featuring independent McPherson struts at the front and a torsion beam at the rear, providing a comfortable ride and stable handling. Braking is handled by ventilated discs at the front and solid discs at the rear, supported by an Anti-lock Braking System (ABS) for enhanced stopping power and control. The electric power steering system, with a steering rack and pinion setup, offers precise and effortless maneuverability, evidenced by a minimum turning circle of 35.1 feet (10.7 meters). The standard tire sizes are 225/45 R17 or 225/40 R18, providing ample grip and contributing to the vehicle’s dynamic capabilities.
