2015 Citroen DS4 1.6 THP (165 Hp) Automatic Stop&Start

Technical Specifications

The Citroen DS4 1.6 THP (165 hp) Automatic Stop&Start, produced between January 2015 and October 2015, represents a mid-range offering within the first generation DS4 lineup (Y3 platform). Positioned as a more accessible entry point into the DS4 range, it combined the 1.6-liter turbocharged petrol engine with a six-speed automatic transmission and Citroen’s Stop&Start technology. This variant aimed to balance performance with fuel economy, appealing to buyers seeking a comfortable and stylish hatchback with modern conveniences. The DS4, in general, was Citroen’s attempt to move upmarket, offering a more premium alternative to the mainstream C4 while still retaining a degree of practicality.

Powertrain & Engine Architecture

At the heart of the DS4 1.6 THP Automatic Stop&Start is the PSA Group’s 1.6-liter turbocharged four-cylinder petrol engine, specifically the EP6DT or EP6FDT variants. This engine is part of the Prince engine family, a collaborative effort between PSA and BMW. It features direct fuel injection, a twin-scroll turbocharger, and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine produces 165 horsepower at 6000 rpm, and 240 Nm (177 lb-ft) of torque is readily available from 1400 rpm, providing good low-end responsiveness. The Stop&Start system automatically shuts off the engine when the vehicle is stationary to improve fuel efficiency. The engine is paired with a six-speed automatic transmission, designed for smooth gear changes, though it doesn’t prioritize sporty performance. This transmission was a popular choice for drivers valuing comfort and ease of use.

Driving Characteristics

The DS4 1.6 THP Automatic delivers a comfortable and refined driving experience. The automatic transmission provides smooth transitions between gears, although it isn’t particularly quick-shifting. Acceleration from 0-60 mph takes approximately 9 seconds, which is adequate for everyday driving but doesn’t offer particularly brisk performance. The turbocharger provides a noticeable power boost, but the engine can feel somewhat strained when pushed hard. The suspension, tuned for comfort, effectively absorbs bumps and road imperfections, but this can also lead to some body roll during cornering. Compared to the more powerful DS4 models, such as those equipped with the 2.0-liter BlueHDi diesel engine, the 1.6 THP Automatic feels less energetic, but it offers a lighter and more agile feel. Compared to the manual version of the same engine, the automatic sacrifices some responsiveness for convenience.

Equipment & Trim Levels

The DS4 1.6 THP Automatic Stop&Start typically came equipped with a reasonable level of standard features. These included air conditioning, a touchscreen infotainment system with Bluetooth connectivity, alloy wheels, and a leather-wrapped steering wheel. Higher trim levels offered additional features such as automatic headlights and wipers, parking sensors, a panoramic sunroof, and upgraded interior upholstery. Interior materials were generally of good quality, contributing to a premium feel. The DS4’s distinctive dashboard design, with its wave-like motif, added to its unique character.

Chassis & Braking

The DS4 utilizes a McPherson strut front suspension and a semi-independent coil spring rear suspension. This setup prioritizes ride comfort over outright handling precision. The front brakes are ventilated discs, providing good stopping power, while the rear brakes are solid discs. ABS (Anti-lock Braking System) is standard. The DS4’s chassis is relatively lightweight, contributing to its fuel efficiency and agility. The steering is electrically assisted, providing a light and easy feel.

Market Reception & Comparison

The DS4 1.6 THP Automatic Stop&Start was generally well-received by critics as a stylish and comfortable hatchback. However, some reviewers noted that the automatic transmission could feel sluggish at times, and the engine lacked the punch of some of its rivals. Fuel economy was a strong point, with combined figures around 42.8 US mpg. Compared to the diesel-powered DS4 models, the 1.6 THP offered a more refined driving experience but lower fuel economy. Against competitors like the Volkswagen Golf and Audi A3, the DS4 stood out with its distinctive styling and comfortable ride, but it didn’t quite match their overall refinement or driving dynamics.

Legacy

The 1.6 THP engine, while generally reliable, has been known to exhibit issues with carbon buildup on the intake valves, particularly if not regularly driven on longer journeys. This is a common issue with direct injection engines. The automatic transmission, if properly maintained, is typically durable. Today, the DS4 1.6 THP Automatic Stop&Start represents an affordable entry point into the DS4 range on the used car market. Its combination of style, comfort, and reasonable fuel economy continues to appeal to buyers seeking a distinctive and practical hatchback. Regular servicing, including oil changes and periodic intake valve cleaning, is crucial to ensure the long-term reliability of this powertrain. Finding a well-maintained example with a documented service history is highly recommended for potential buyers.
