2015-2018 DS 5 1.6 THP (165 Hp) Stop&Start Automatic

The DS 5 1.6 THP 165 Stop&Start Automatic was a variant of the DS 5 compact hatchback produced between 2015 and 2018. Positioned as a mid-range offering within the DS 5 lineup, it aimed to balance performance and fuel efficiency with the convenience of an automatic transmission. The DS 5 itself was a distinctive vehicle, originally conceived as the Citroën DS5 before the DS Automobiles brand was established as a separate entity focusing on premium vehicles. This variant utilized the PSA Group’s 1.6 THP engine paired with a six-speed automatic gearbox, incorporating Stop&Start technology for improved fuel economy. It was primarily marketed in Europe, where the DS brand sought to establish itself as a competitor to established premium automakers.

Technical Specifications

Powertrain & Engine Architecture

The heart of the DS 5 1.6 THP 165 Stop&Start Automatic is the PSA Group’s EP6FDT engine, a 1.6-liter turbocharged inline-four cylinder petrol engine. This engine is part of the Prince engine family, developed jointly by PSA and BMW. The ‘THP’ designation stands for Turbo High Pressure, indicating the use of a twin-scroll turbocharger and direct fuel injection. The engine utilizes a sophisticated direct injection system, delivering fuel directly into the combustion chamber for improved efficiency and power. It features a variable valve timing system on both intake and exhaust valves, optimizing engine performance across the rev range. The Stop&Start system automatically shuts off the engine when the vehicle is stationary (at traffic lights, for example) and restarts it instantly when the driver depresses the clutch or brake pedal, reducing fuel consumption and emissions. The engine is transversely mounted at the front of the vehicle. The six-speed automatic transmission, an Aisin-sourced unit, was chosen for its smooth operation and efficiency. It features a torque converter and electronic control for optimized gear selection.

Driving Characteristics

The 165 horsepower and 240 Nm (177 lb-ft) of torque provided by the 1.6 THP engine, coupled with the six-speed automatic, resulted in a respectable, though not particularly sporty, driving experience. Acceleration from 0 to 60 mph took around 9.2 seconds, and the top speed was 125.52 mph. The automatic transmission, while smooth, wasn’t known for its particularly quick shifts. Compared to the more powerful DS 5 variants, such as those equipped with the 2.0-liter BlueHDi diesel engine, the 1.6 THP felt less responsive, particularly during overtaking maneuvers. However, it offered a more refined and quieter driving experience than the diesel. The automatic transmission’s gear ratios were tuned for fuel efficiency rather than outright performance. In real-world driving, the engine provided adequate power for everyday commuting and highway cruising. The Stop&Start system, while effective in reducing fuel consumption, could sometimes feel slightly intrusive during stop-and-go traffic.

Equipment & Trim Levels

The DS 5 1.6 THP 165 Stop&Start Automatic typically came equipped with a good level of standard equipment. This included features such as automatic climate control, a touchscreen infotainment system with navigation, Bluetooth connectivity, and rear parking sensors. Interior upholstery was generally a combination of cloth and leather, with a focus on comfort and quality. Higher trim levels offered upgrades such as full leather upholstery, panoramic sunroof, and advanced driver-assistance systems like blind-spot monitoring and adaptive cruise control. The DS 5’s interior was known for its unique ‘cockpit’ design, featuring a high center console and numerous toggle switches, inspired by aviation aesthetics. Optional extras included a premium sound system and various cosmetic enhancements.

Chassis & Braking

The DS 5 featured a McPherson strut front suspension and a semi-independent coil spring rear suspension. This setup provided a comfortable ride quality, although it wasn’t particularly sporty in handling. Stabilizer bars were fitted to both the front and rear axles to reduce body roll. Braking duties were handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) was standard, providing enhanced braking performance and stability. The steering was electrically assisted, offering a light and precise feel.

Market Reception & Comparison

The DS 5 1.6 THP 165 Stop&Start Automatic was generally well-received by automotive critics. It was praised for its comfortable ride, refined interior, and fuel efficiency. However, some critics noted that the engine lacked the punch of its diesel counterparts and that the automatic transmission wasn’t the most responsive on the market. Compared to other petrol-powered automatic hatchbacks in its class, the DS 5 offered a unique and stylish alternative. Fuel economy figures of around 39.9 US mpg (combined) were competitive for the segment. Reliability was generally good, although some owners reported minor issues with the Stop&Start system.

Legacy

The DS 5, and specifically the 1.6 THP 165 Stop&Start Automatic variant, represents an interesting chapter in the DS Automobiles brand’s early history. While the DS 5 itself was discontinued in 2018, the 1.6 THP engine continued to be used in other PSA Group vehicles. On the used car market, the DS 5 1.6 THP 165 Automatic offers a relatively affordable entry point into the DS brand. The engine is generally considered reliable, but regular maintenance, including oil changes and timing belt replacements, is crucial. The Stop&Start system may require occasional attention. Overall, the DS 5 1.6 THP 165 Stop&Start Automatic remains a distinctive and comfortable hatchback with a unique design and a reasonable level of equipment.
