The DS N°4 II (facelift 2025) 1.2 (145 Hp) Hybrid eDCT represents a significant evolution in DS Automobiles’ compact crossover offering, launched in June 2025. Positioned as a mid-range option within the N°4 lineup, this variant blends a turbocharged three-cylinder gasoline engine with a 48-volt mild hybrid system, paired with a six-speed dual-clutch transmission (eDCT). It builds upon the foundation of the original N°4, which debuted as DS’s entry into the highly competitive C-segment crossover market, aiming to provide a balance of fuel efficiency, performance, and sophisticated styling. The facelifted model introduces updated aesthetics, enhanced technology, and refinements to the powertrain for improved real-world usability.

Powertrain & Engine Architecture
At the heart of the DS N°4 II 1.2 Hybrid eDCT lies the HN09 engine, a 1.2-liter turbocharged three-cylinder gasoline engine. This engine produces 136 horsepower at 5500 rpm and 230 Nm (169.64 lb.-ft.) of torque at 1750 rpm. Direct fuel injection and a turbocharger with an intercooler contribute to its efficiency and responsiveness. The ‘Hybrid’ designation refers to a 48-volt mild hybrid system. This system incorporates a small electric motor (28 hp and 51 Nm of torque) integrated with the eDCT transmission, and a lithium-ion battery with a gross capacity of 0.88 kWh located under the front seats. The system allows for regenerative braking, providing a small boost during acceleration, and enabling a start/stop system for improved fuel economy. The six-speed eDCT (efficient Dual-Clutch Transmission) provides quick and smooth gear changes, enhancing the driving experience.
Driving Characteristics
The 145 hp combined output delivers adequate performance for everyday driving. Acceleration from 0 to 100 km/h (0-62 mph) takes 9.5 seconds. While not a performance-oriented variant, the eDCT transmission and the electric motor assist provide a noticeable improvement in responsiveness compared to a non-hybrid version. The mild hybrid system doesn’t offer full electric driving capability, but it does smooth out the engine’s operation and contributes to a more refined driving experience. The eDCT transmission is well-tuned for fuel efficiency, with gear ratios optimized for both city and highway driving. Compared to higher-output versions of the N°4, this variant prioritizes fuel economy and comfort over outright speed.
Equipment & Trim Levels
The 1.2 Hybrid eDCT trim typically includes standard features such as automatic climate control, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a suite of driver-assistance systems including lane departure warning, automatic emergency braking, and traffic sign recognition. Interior upholstery is generally cloth, with options for leather upgrades. Available options include a panoramic sunroof, premium audio system, and advanced parking assist features. The overall interior design emphasizes a modern and upscale aesthetic, consistent with the DS Automobiles brand.
Chassis & Braking
The DS N°4 II utilizes a front-wheel-drive platform with a MacPherson strut front suspension and a torsion beam rear suspension. The braking system consists of ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard. The suspension is tuned for comfort, providing a relatively smooth ride quality. The steering is an electric power-assisted rack and pinion system, offering a balance of precision and ease of use.
Market Reception & Comparison
The DS N°4 II 1.2 Hybrid eDCT has been generally well-received by automotive critics for its fuel efficiency and comfortable ride. Compared to the more powerful gasoline and diesel variants, this trim offers a lower price point and improved fuel economy, making it an attractive option for budget-conscious buyers. However, some reviewers have noted that the performance is not as exhilarating as that of the higher-output models. The mild hybrid system provides a noticeable improvement in fuel economy compared to the non-hybrid versions, but it doesn’t offer the same level of electric driving range as a plug-in hybrid.
Legacy
The HN09 engine and eDCT transmission combination has proven to be relatively reliable in other PSA Group (now Stellantis) vehicles. The mild hybrid system, while relatively new, is expected to contribute to long-term durability. On the used car market, the DS N°4 II 1.2 Hybrid eDCT is likely to appeal to buyers seeking a stylish, fuel-efficient, and well-equipped crossover. Its combination of modern technology and comfortable driving characteristics should ensure its continued popularity in the years to come.
