Powertrain & Engine Architecture
At the heart of the 508 SW 1.6 PureTech Plug-in Hybrid lies the EP6FDT engine, a 1.6-liter turbocharged inline-four cylinder gasoline engine. This engine, part of Peugeot’s PureTech family, utilizes direct fuel injection and a twin-scroll turbocharger to deliver 150 horsepower at 6000 rpm and 300 Nm (221 lb-ft) of torque at 3000 rpm. The engine features a DOHC valvetrain and operates on a Miller cycle for improved efficiency. Coupled with this is a 110 horsepower electric motor integrated between the engine and the eight-speed automatic transmission (e-EAT8). The 12.4 kWh lithium-ion battery pack, positioned under the rear seats and floor, provides an all-electric range of up to 64 km (39.77 miles) under WLTP testing. The e-EAT8 transmission is specifically tuned to work seamlessly with the electric motor, offering smooth transitions between electric, hybrid, and gasoline power modes.
Driving Characteristics
The 180 hp combined output of the 1.6 PureTech Plug-in Hybrid provides adequate performance for everyday driving. While not as overtly sporty as higher-powered 508 variants, the electric motor provides instant torque, resulting in brisk acceleration from a standstill. The e-EAT8 transmission offers smooth and responsive gear changes, although it can sometimes feel hesitant during kickdown maneuvers. In electric mode, the 508 SW operates silently and efficiently, ideal for urban commutes. The hybrid system intelligently manages power delivery, prioritizing electric power whenever possible and seamlessly engaging the gasoline engine when needed. Compared to the 1.5 BlueHDi diesel or the 225 hp PureTech gasoline models, this variant prioritizes fuel efficiency and low emissions over outright performance.
Equipment & Trim Levels
The 508 SW 1.6 PureTech Plug-in Hybrid typically came equipped with a generous level of standard features. These included Peugeot’s i-Cockpit interior design with a compact steering wheel and a 10-inch touchscreen infotainment system, automatic climate control, keyless entry and start, and a suite of advanced driver-assistance systems (ADAS) such as lane keeping assist, adaptive cruise control, and automatic emergency braking. Interior upholstery was typically a combination of cloth and synthetic leather, with optional upgrades to full leather available. Higher trim levels added features like a panoramic sunroof, premium audio system, and ventilated front seats.
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 comfortable ride quality and good handling characteristics. Stabilizer bars are fitted to both axles to reduce body roll. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The ABS system, coupled with electronic brakeforce distribution, ensures effective stopping power in various conditions. The weight of the battery pack, while contributing to a lower center of gravity, does add to the overall vehicle weight, impacting handling slightly compared to lighter 508 variants.
Market Reception & Comparison
The Peugeot 508 SW 1.6 PureTech Plug-in Hybrid was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and stylish design. However, some reviewers noted that the all-electric range was somewhat limited compared to some competitors. Compared to the diesel-powered 508 SW models, the plug-in hybrid offered lower emissions and a quieter driving experience, but at a higher initial cost. Against other plug-in hybrid estate cars, the 508 SW offered a compelling combination of practicality, performance, and value.
Legacy
The 1.6 PureTech engine, while generally reliable, has been subject to some reports of timing chain issues in certain applications. Regular maintenance, including oil changes and adherence to Peugeot’s recommended service intervals, is crucial for ensuring the longevity of this powertrain. The hybrid system components, including the battery pack and electric motor, have proven to be relatively durable. As a used car, the 508 SW 1.6 PureTech Plug-in Hybrid represents a good value proposition for buyers seeking a fuel-efficient and well-equipped estate car. Its blend of practicality, technology, and style continues to make it an attractive option in the used car market.
