The Peugeot 408 Plug-in Hybrid 1.6 (180 hp) e-EAT8, launched in June 2022 and produced through June 2024, represents a significant entry in Peugeot’s expanding crossover lineup. Positioned as a mid-range offering within the 408 series, this variant combines a 1.6-liter turbocharged gasoline engine with an electric motor and a sophisticated eight-speed automatic transmission (e-EAT8). It’s designed to appeal to buyers seeking a blend of fuel efficiency, reduced emissions, and a more dynamic driving experience than traditionally offered by mainstream crossovers. The 408 itself is a relatively new model, aiming to carve out a niche between the more compact 3008 and the larger 5008 SUVs, offering a coupe-like silhouette and a focus on style.

Powertrain & Engine Architecture
At the heart of the 408 Plug-in Hybrid 1.6 is Peugeot’s DGX EP6FADTXHPE engine, a 1.6-liter turbocharged inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and is paired with an electric motor integrated between the engine and the e-EAT8 eight-speed automatic transmission. The electric motor contributes 110 hp and 320 Nm (236 lb-ft) of torque, supplementing the gasoline engine’s 150 hp and 250 Nm (184 lb-ft). The combined system output is 180 hp and 360 Nm (265 lb-ft) of torque. The e-EAT8 transmission is specifically tuned to work seamlessly with the electric motor, providing smooth transitions between electric, hybrid, and gasoline power modes. The 12.4 kWh lithium-ion battery pack allows for an all-electric range of approximately 35-40 miles (depending on driving conditions), making it suitable for daily commutes and shorter trips. The engine also features a particulate filter to meet stringent Euro 6.4 emissions standards.
Driving Characteristics
The 1.8L Plug-in Hybrid powertrain delivers a refined and responsive driving experience. In electric mode, the 408 offers near-silent operation and brisk acceleration for urban driving. When the gasoline engine engages, the transition is generally smooth and unobtrusive. The e-EAT8 transmission provides quick and precise gear changes, contributing to a feeling of effortless performance. While not a sports car, the combined output of 180 hp provides adequate power for highway merging and overtaking. Compared to the standard gasoline-powered 408 variants, the Plug-in Hybrid offers improved fuel economy and reduced emissions. However, the added weight of the battery pack and electric motor does slightly impact handling agility compared to lighter models. The gear ratios are optimized for both efficiency and responsiveness, with a focus on maximizing torque delivery at lower speeds.
Equipment & Trim Levels
The 1.6 Plug-in Hybrid 180 hp e-EAT8 trim typically came well-equipped, often positioned as a mid-range offering. Standard features generally included a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a digital instrument cluster, automatic climate control, 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 options for full leather available. Optional extras included a panoramic sunroof, premium audio system, and upgraded wheels. The trim level also featured unique badging and exterior styling cues to differentiate it from other 408 variants.
Chassis & Braking
The Peugeot 408 utilizes a front-wheel-drive platform with a MacPherson strut front suspension and a multi-link rear suspension. The suspension is tuned to provide a comfortable ride while maintaining reasonable handling characteristics. Braking duties are handled by ventilated discs at the front and solid discs at the rear, equipped with ABS and electronic brakeforce distribution. The steering system is an electric power-assisted rack and pinion system, offering precise and responsive steering feel. The vehicle’s weight distribution is influenced by the placement of the battery pack, which is typically located under the floor of the passenger compartment. Tire sizes varied depending on the trim level, with options ranging from 205/55 R19 to 245/40 R20.
Market Reception & Comparison
The Peugeot 408 Plug-in Hybrid 1.6 received generally positive reviews from 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 gasoline-powered 408 variants, the Plug-in Hybrid offered significantly improved fuel economy and reduced emissions, but at a higher purchase price. Compared to other plug-in hybrid crossovers in the same segment, such as the Toyota RAV4 Prime or the Mitsubishi Outlander PHEV, the 408 offered a more European driving experience and a more distinctive design. Reliability reports have been generally positive, with few major issues reported with the powertrain.
Legacy
The Peugeot 408 Plug-in Hybrid 1.6 represents a step forward in Peugeot’s commitment to electrification. The powertrain, while not without its limitations, has proven to be relatively reliable in early model years. On the used car market, these models are becoming increasingly attractive to buyers seeking a fuel-efficient and environmentally friendly crossover. The e-EAT8 transmission has also gained a reputation for smoothness and durability. As battery technology continues to improve, the 408 Plug-in Hybrid is likely to remain a viable option for buyers seeking a practical and stylish plug-in hybrid crossover.
