The Peugeot 408 II 1.8 CVVT Automatic, produced between 2014 and 2017, represented a key offering in Peugeot’s mid-size sedan lineup. Positioned as a comfortable and efficient option, this variant aimed to balance performance with affordability within the broader 408 II range, which also included diesel and higher-horsepower gasoline engines. Built on the Peugeot-Citroën PSA Group’s EMP2 platform, the 408 II sought to modernize Peugeot’s presence in a competitive segment, particularly in European and Asian markets. This specific 1.8L configuration was often considered an entry-to-mid-level trim, appealing to buyers prioritizing fuel economy and a smooth driving experience over outright performance.

Powertrain & Engine Architecture
The heart of the 408 II 1.8 CVVT Automatic is the EC8 engine, a 1.8-liter inline-four cylinder gasoline engine. This engine utilizes a naturally aspirated configuration and benefits from Peugeot’s Variable Valve Timing (CVVT) technology, designed to optimize engine performance and fuel efficiency across a wider range of engine speeds. The EC8 engine features direct fuel injection, contributing to cleaner combustion and improved throttle response. The engine produces 139 horsepower and 172 Nm (126.86 lb.-ft.) of torque. This power is then channeled through a six-speed automatic transmission, a common choice for drivers seeking convenience and ease of use. The transmission is tuned for smooth shifts and efficient operation, prioritizing comfort over sporty responsiveness.
Driving Characteristics
The 1.8L Automatic 408 II delivers a comfortable and predictable driving experience. Acceleration is adequate for everyday driving, but it’s not particularly brisk. The six-speed automatic transmission is programmed to prioritize fuel economy, meaning it will upshift quickly to maintain lower engine speeds. This can sometimes result in a slight hesitation when requesting sudden bursts of power, such as when overtaking. Compared to the more powerful 1.6 THP turbocharged engine or the diesel options, the 1.8L feels noticeably less energetic. However, the automatic transmission provides a smooth and refined experience, making it well-suited for city driving and long highway journeys. The gear ratios are optimized for cruising, keeping engine noise to a minimum at higher speeds.
Equipment & Trim Levels
The 1.8 CVVT Automatic trim typically included standard features such as air conditioning, power windows, power mirrors, a basic audio system with USB connectivity, and ABS brakes. Higher trim levels, often available as optional packages, added features like alloy wheels, a touchscreen infotainment system, rear parking sensors, cruise control, and automatic headlights and wipers. Interior upholstery was generally cloth, with the option of leather seats on higher-spec models. The dashboard layout was functional and ergonomically designed, with a focus on ease of use. Safety features included multiple airbags and stability control.
Chassis & Braking
The 408 II utilizes a McPherson strut front suspension and an independent coil spring rear suspension. This setup provides a good balance between ride comfort and handling. The front suspension incorporates an anti-roll bar to reduce body roll during cornering. Braking duties are handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard, enhancing braking performance and stability, particularly on slippery surfaces. The steering is electrically assisted, providing light and precise control.
Market Reception & Comparison
The Peugeot 408 II 1.8 CVVT Automatic was generally well-received by critics as a practical and affordable mid-size sedan. It was praised for its comfortable ride, fuel efficiency, and well-equipped interior. However, some reviewers noted that the engine lacked the punch of its turbocharged counterparts. Compared to the diesel versions, the 1.8L offered lower running costs in terms of fuel price but sacrificed fuel economy. Against the 1.6 THP, it provided a smoother, less aggressive driving experience but with reduced performance. The 1.8L Automatic appealed to buyers who prioritized comfort and economy over sporty driving dynamics.
Legacy
The EC8 engine, while not known for being a high-performance unit, has proven to be relatively reliable over the long term. Common maintenance items include regular oil changes, timing belt replacement (depending on mileage), and spark plug replacement. The six-speed automatic transmission is also generally durable, provided it is serviced according to the manufacturer’s recommendations. In the used car market, the 408 II 1.8 CVVT Automatic represents a good value proposition for buyers seeking a comfortable and economical mid-size sedan. Its relatively simple engine design and readily available parts contribute to lower maintenance costs compared to more complex turbocharged or diesel engines. While it may not be the most exciting car to drive, it offers a practical and dependable transportation solution.
