Introduction
The 508L II Phase II 1.8 Aisin is a key variant within the broader 508L range, specifically designed for the Chinese automotive market. The “L” designation signifies an extended wheelbase, adding approximately 80mm to the standard 508, resulting in increased rear legroom – a crucial factor for Chinese consumers. The Phase II update, launched in 2023, brought subtle exterior styling changes, interior enhancements, and refinements to the powertrain. This 1.8-liter turbocharged engine paired with the Aisin 8-speed automatic transmission represents a mid-range offering, positioned between the more affordable base models and the higher-performance variants.
Powertrain & Engine Architecture
At the heart of this 508L variant lies the Peugeot-Citroën EP6C engine, a 1.8-liter turbocharged inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and a twin-scroll turbocharger to deliver a balance of power and efficiency. The engine code is often associated with variations like ETN, depending on specific calibration and market requirements. The engine features a continuously variable valve timing (CVVT) system on both intake and exhaust valves, optimizing performance across the rev range. The Aisin 8-speed automatic transmission (often designated as A8) is a torque converter automatic known for its smooth shifting and responsiveness. It’s a widely used transmission found in various vehicles across different manufacturers. The transmission’s gear ratios are tuned to provide a blend of acceleration and fuel economy, with a focus on comfortable cruising at highway speeds.
Driving Characteristics
The 508L II 1.8 Aisin delivers a refined and comfortable driving experience. While not as overtly sporty as some of its rivals, the 211 hp output provides ample power for everyday driving and overtaking maneuvers. The Aisin transmission contributes to smooth gear changes, minimizing harshness and enhancing overall comfort. Compared to manual transmission versions (where available in other markets), the automatic offers convenience and ease of use, particularly in congested urban environments. The torque curve, peaking at 300 Nm between 1900 and 4500 rpm, ensures strong mid-range acceleration. The extended wheelbase of the 508L contributes to a stable and composed ride, absorbing bumps and imperfections in the road surface effectively. The steering is precise and well-weighted, providing a confident feel behind the wheel.
Equipment & Trim Levels
The 508L II 1.8 Aisin typically comes well-equipped, reflecting its positioning as a mid-range offering. Standard features generally include automatic climate control, a touchscreen infotainment system with smartphone integration (Apple CarPlay and Android Auto), a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane departure warning, and automatic emergency braking, and premium upholstery. Higher trim levels offer additional features such as a panoramic sunroof, leather seats with massage function, a premium sound system, and advanced parking assist systems. Interior color schemes typically include black, grey, and beige options.
Chassis & Braking
The 508L II utilizes a McPherson strut front suspension and a multi-link rear suspension, providing a good balance of ride comfort and handling. The suspension is tuned to prioritize comfort, but still offers reasonable body control in corners. The braking system consists of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. Anti-lock braking system (ABS) and electronic brake-force distribution (EBD) are standard features. The steering system employs an electric power steering (EPS) system, offering light and precise steering feel.
Market Reception & Comparison
The Peugeot 508L II has been well-received in the Chinese market, praised for its stylish design, spacious interior, and comfortable ride. The 1.8-liter Aisin variant strikes a good balance between performance and fuel economy, making it a popular choice among buyers who prioritize practicality and efficiency. Compared to higher-output engine options, the 1.8L offers lower running costs, while still providing sufficient power for most driving situations. Competitors in the Chinese market include the Volkswagen Passat, Audi A6L, and Toyota Camry, all of which offer similar levels of comfort and refinement. The 508L often stands out due to its distinctive styling and European flair.
Legacy
The Peugeot 508L II 1.8 Aisin, while relatively new to the market, is expected to have good long-term reliability. The Aisin transmission is known for its durability, and the EP6C engine has proven to be a reliable unit in other Peugeot and Citroën models. As the vehicle ages, maintaining the turbocharger and fuel injection system will be crucial for optimal performance. In the used car market, this variant is likely to hold its value well, particularly among buyers who appreciate its blend of style, comfort, and efficiency. Its focus on the Chinese market means its long-term presence outside of China may be limited, but within China, it represents a significant offering in the competitive mid-size executive sedan segment.
