Powertrain & Engine Architecture
At the heart of the 508 SW 1.6 THP is the PSA Group’s EP6FDT engine, a 1.6-liter turbocharged inline-four cylinder gasoline engine. This engine is part of the Prince engine family, developed in collaboration with BMW. The “THP” designation stands for Turbo High Pressure, indicating the use of a twin-scroll turbocharger and direct fuel injection. The direct injection system, operating at pressures up to 200 bar, ensures precise fuel delivery for optimal combustion and efficiency. The engine utilizes a variable valve timing system on both intake and exhaust valves, further enhancing performance and responsiveness. The 5GZ engine code specifically denotes a version tuned to produce 156 horsepower. This power is delivered through a six-speed automatic transmission, offering smooth gear changes and contributing to the vehicle’s overall refinement. The transmission is a conventional torque-converter automatic, prioritizing comfort over outright sportiness.
Driving Characteristics
The 1.6 THP automatic 508 SW offers a comfortable and composed driving experience. While not particularly sporty, the engine provides adequate power for everyday driving and highway cruising. Acceleration from 0-60 mph takes around 8.6 seconds, which is respectable for a mid-size station wagon. The automatic transmission is well-matched to the engine’s torque curve, providing smooth and predictable shifts. However, it can sometimes feel hesitant during quick overtaking maneuvers. Compared to the more powerful 181 hp version of the 1.6 THP or the diesel variants, this setup prioritizes fuel economy over outright performance. The gear ratios are tuned for efficiency, resulting in a relaxed driving experience at cruising speeds. The steering is light and precise, making the car easy to maneuver in urban environments.
Equipment & Trim Levels
The 508 SW 1.6 THP Automatic typically came equipped with a reasonable level of standard features. These included air conditioning, a touchscreen infotainment system with Bluetooth connectivity, alloy wheels, and a suite of safety features such as ABS, ESP (Electronic Stability Program), and multiple airbags. Higher trim levels, such as Allure or Feline, added features like leather upholstery, a panoramic sunroof, parking sensors, and a more advanced infotainment system with navigation. Optional extras included a head-up display, adaptive cruise control, and a premium sound system.
Chassis & Braking
The 508 SW utilizes a McPherson strut front suspension and a multi-link rear suspension, providing a good balance between ride comfort and handling. The suspension is tuned for comfort, absorbing bumps and imperfections in the road surface effectively. The front brakes are ventilated discs, while the rear brakes are solid discs. ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) are standard features, enhancing safety and stability. The steering is a rack and pinion system, providing precise and responsive steering feel.
Market Reception & Comparison
The Peugeot 508 SW 1.6 THP Automatic was generally well-received by automotive critics. It was praised for its stylish design, spacious interior, and comfortable ride. The 1.6 THP engine was considered a good compromise between performance and fuel economy. However, some critics noted that the automatic transmission could be slow to respond at times. Compared to its rivals, such as the Ford Mondeo Estate and the Volkswagen Passat Variant, the 508 SW offered a more distinctive design and a more refined interior. Fuel economy was competitive, averaging around 40.6 US mpg in combined driving. Reliability was generally good, although some owners reported minor issues with the engine’s turbocharger and fuel injection system.
Legacy
The Peugeot 508 SW 1.6 THP Automatic remains a popular choice in the used car market. Its combination of practicality, comfort, and fuel efficiency makes it an attractive option for families and individuals seeking a versatile station wagon. The 1.6 THP engine, while not without its quirks, has proven to be relatively reliable when properly maintained. Regular servicing, including oil changes and timing belt replacements, is crucial for ensuring the longevity of this powertrain. Today, these vehicles represent a good value proposition, offering a lot of car for the money.
