The Peugeot 508L II, specifically the Phase I model produced from 2019 to 2023, represented a significant evolution for Peugeot’s mid-size sedan. The 400 THP PureTech variant, equipped with a 1.8-liter turbocharged four-cylinder engine producing 211 horsepower and an eight-speed automatic transmission, was positioned as a premium offering within the 508L lineup. The “L” designation indicated a long-wheelbase version, primarily aimed at the Chinese market, offering increased rear passenger space compared to the standard 508 sold in Europe. This model aimed to blend European styling with the practicality demanded by Chinese consumers, competing with established players like the Audi A6L and BMW 5 Series Li.

Powertrain & Engine Architecture
The heart of the 508L II 400 THP PureTech is the EP6CDT engine, a 1.8-liter inline-four cylinder gasoline engine. This engine belongs to Peugeot’s PureTech family, known for its direct injection and turbocharging. The engine utilizes a single-scroll turbocharger with an intercooler to boost power and efficiency. Direct injection allows for precise fuel delivery, optimizing combustion and reducing emissions. The engine’s valvetrain features variable valve timing on both intake and exhaust sides, further enhancing performance and fuel economy. The eight-speed automatic transmission, sourced from Aisin, was chosen for its smooth shifting and efficiency. This transmission features a wide gear ratio spread, contributing to both acceleration and highway cruising comfort. The transmission is electronically controlled, adapting to driving conditions and driver input.
Driving Characteristics
The 211 horsepower and 300 Nm (221 lb-ft) of torque delivered by the 1.8-liter engine, coupled with the eight-speed automatic, provided a responsive and refined driving experience. While not a sports sedan, the 508L II 400 THP offered brisk acceleration, with a 0-60 mph time estimated around 8.0-8.5 seconds. The automatic transmission’s programming prioritized smooth shifts and fuel efficiency, but also offered a sport mode for more aggressive acceleration. Compared to lower-powered variants of the 508L, such as the 160 THP, the 400 THP provided a noticeable performance upgrade. It also offered a more relaxed driving experience on the highway, thanks to the wider gear ratios and increased power. Compared to the diesel options available in Europe, the 400 THP offered a more refined and quieter driving experience, albeit with potentially higher fuel consumption.
Equipment & Trim Levels
The 400 THP PureTech trim typically came well-equipped, reflecting its position as a premium offering. Standard features included leather upholstery, a panoramic sunroof, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane keeping assist, and automatic emergency braking. Optional extras included a premium sound system, ventilated front seats, and a head-up display. Interior trim levels varied, with options for different wood or metal accents. The dashboard layout was modern and driver-focused, with a compact steering wheel and a digital instrument cluster.
Chassis & Braking
The 508L II utilized a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable and controlled ride. The suspension was tuned to balance ride comfort with handling precision. The long wheelbase of the 508L contributed to a stable and composed ride, particularly at highway speeds. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) and electronic brakeforce distribution (EBD) were standard features. Steering was provided by an electric power steering system, offering light and precise steering feel.
Market Reception & Comparison
The Peugeot 508L II 400 THP PureTech was generally well-received by automotive critics in China. Reviewers praised its stylish design, comfortable interior, and refined driving experience. The 1.8-liter engine was considered adequate for most driving situations, and the eight-speed automatic transmission was lauded for its smoothness. Fuel economy was competitive within its segment, although not as efficient as the diesel options available in other markets. Compared to its rivals, such as the Audi A6L and BMW 5 Series Li, the 508L offered a more distinctive design and a slightly more affordable price point. However, it lacked the brand prestige of its German competitors.
Legacy
The Peugeot 508L II 400 THP PureTech represents a significant step forward for Peugeot in the Chinese market. The EP6CDT engine has proven to be a reliable unit, although long-term maintenance costs can be higher compared to simpler engines. On the used car market, these models hold their value reasonably well, particularly those in good condition with low mileage. The combination of stylish design, comfortable interior, and refined driving experience continues to appeal to buyers looking for a premium mid-size sedan. While Peugeot’s presence in China has fluctuated, the 508L remains a notable example of the brand’s efforts to cater to the specific needs and preferences of Chinese consumers.
