INTRODUCTION
The Peugeot 508 II SW 1.6 PureTech 225 e-EAT8 is a five-door, five-seat station wagon that debuted with the Phase II update in 2023. It represents Peugeot’s commitment to providing a compelling alternative to traditional gasoline and diesel vehicles, offering a blend of performance, efficiency, and practicality. This model sits towards the higher end of the 508 SW range, offering a significant power boost and the benefits of electric-only driving compared to the lower-powered gasoline and diesel options. The “SW” designation signifies the station wagon body style, offering increased cargo capacity compared to the sedan version of the 508.
Powertrain & Engine Architecture
At the heart of the 508 SW 1.6 PureTech 225 is the EP6 CDT engine, a 1.6-liter turbocharged inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and a twin-scroll turbocharger to deliver 180 horsepower at 6000 rpm and 300 Nm (221 lb-ft) of torque at 3000 rpm. The “PureTech” designation signifies Peugeot’s family of three and four-cylinder gasoline engines. The engine is paired with a 110 hp electric motor integrated between the engine and the eight-speed automatic transmission (e-EAT8). The electric motor draws power from a 12.4 kWh lithium-ion battery pack located under the rear seats and floor. The combined system output is 225 hp and 360 Nm (265 lb-ft) of torque. The e-EAT8 transmission is specifically tuned to work seamlessly with the electric motor, providing smooth transitions between electric, hybrid, and gasoline power modes. The engine utilizes a timing chain, reducing maintenance compared to timing belts.
Driving Characteristics
The 508 SW 1.6 PureTech 225 offers a refined and versatile driving experience. In electric mode, the vehicle provides near-silent operation and a range of up to 64 km (39.77 miles) under WLTP testing. Switching to hybrid mode allows the engine and electric motor to work in tandem, providing brisk acceleration – 0-100 km/h in 8 seconds. The e-EAT8 transmission offers quick and smooth gear changes, enhancing the overall driving experience. Compared to the 1.5 BlueHDi diesel variant, the plug-in hybrid offers quicker acceleration and a more responsive feel, albeit with a slightly higher kerb weight due to the battery pack. The steering is precise and well-weighted, providing a confident feel on both city streets and highways. The suspension is tuned for comfort, absorbing bumps and imperfections in the road surface effectively.
Equipment & Trim Levels
The 508 SW 1.6 PureTech 225 typically comes well-equipped as a higher-trim level. Standard features often include Peugeot’s i-Cockpit interior design with a compact steering wheel and a 10-inch touchscreen infotainment system, navigation, Apple CarPlay and Android Auto compatibility, automatic climate control, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Interior upholstery is typically a combination of cloth and leather, with options for full leather trim. Optional extras may include a panoramic sunroof, premium audio system, and ventilated front seats. The Phase II update brought subtle styling revisions and upgraded infotainment features.
Chassis & Braking
The 508 SW utilizes an independent suspension setup, with McPherson struts at the front and a multi-link system at the rear. This configuration provides a good balance between ride comfort and handling. The front brakes are ventilated discs measuring 304x28mm, while the rear brakes are solid discs measuring 268x12mm. ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution and emergency brake assist. The steering system is an electric power-assisted rack and pinion system, providing precise and responsive steering feel. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Peugeot 508 SW 1.6 PureTech 225 has been generally well-received by automotive critics, praised for its stylish design, comfortable interior, and efficient powertrain. Compared to the lower-powered gasoline and diesel variants, the plug-in hybrid offers a more refined and engaging driving experience, along with the benefits of electric-only driving. Fuel economy is excellent, particularly for those who can regularly charge the battery. However, the plug-in hybrid variant is more expensive than the base models. Competitors in this segment include the Volkswagen Passat GTE, Skoda Superb iV, and BMW 330e Touring.
Legacy
The Peugeot 508 SW 1.6 PureTech 225 represents a significant step forward in Peugeot’s electrification strategy. The EP6 engine and e-EAT8 transmission combination has proven to be reliable, although, as with any complex powertrain, regular maintenance is crucial. On the used car market, these models are becoming increasingly desirable due to their low running costs and environmental benefits. The long-term durability of the battery pack remains a key consideration for potential buyers, but Peugeot offers an eight-year/100,000-mile warranty on the battery. The 508 SW 1.6 PureTech 225 is likely to be remembered as a stylish and technologically advanced station wagon that helped to pave the way for a more sustainable automotive future.
