Renault Scenic IV (Phase I) 1.7 Blue dCi (150 Hp)

The Renault Scenic IV Phase I 1.7 Blue dCi (150 hp) is a compact minivan produced by the French manufacturer Renault between September 2018 and October 2020. This variant occupied a mid-range position within the Scenic IV lineup, offering a balance between fuel efficiency, performance, and equipment. It was positioned above the lower-powered diesel options and below the petrol-powered variants, targeting families and individuals seeking a practical and economical vehicle for everyday use. The Scenic IV, built on the Common Module Family (CMF) C/D platform, represented Renault’s fourth generation of the Scenic model, known for its innovative interior design and focus on passenger comfort.

Powertrain & Engine Architecture

The heart of the Scenic IV 1.7 Blue dCi (150 hp) is the Renault R9N engine, a 1.7-liter inline four-cylinder diesel engine. This engine is part of Renault’s Blue dCi family, known for its focus on reducing emissions and improving fuel economy. The R9N engine utilizes a common rail direct fuel injection system, operating at a maximum pressure of 1,800 bar, ensuring precise fuel delivery and efficient combustion. It features a single turbocharger with an intercooler, boosting power output and improving throttle response. The engine also incorporates four valves per cylinder, contributing to enhanced volumetric efficiency.

The engine produces 150 horsepower at 3,500 rpm and 340 Nm (250.77 lb-ft) of torque at 1,750 rpm. This torque output provides good low-end grunt, making it suitable for everyday driving and carrying passengers or cargo. The engine is transversely mounted at the front of the vehicle. While a six-speed manual transmission was standard, an optional six-speed Efficient Dual Clutch (EDC) automatic transmission was also available, though less common. The EDC transmission offered smoother gear changes and improved fuel efficiency compared to a traditional automatic.

Engine Specifications

The R9N engine incorporates several technologies to meet stringent Euro 6 emission standards, including a diesel particulate filter (DPF) to trap soot particles and reduce harmful emissions. It also features exhaust gas recirculation (EGR) to lower nitrogen oxide (NOx) emissions. The engine oil capacity is 5.9 liters (6.23 US quarts / 5.19 UK quarts), and the recommended oil specification is specific to Renault’s requirements. The cooling system holds 7 liters (7.4 US quarts / 6.16 UK quarts) of coolant.

Driving Characteristics

The Scenic IV 1.7 Blue dCi (150 hp) offers a comfortable and refined driving experience. The 150 hp output, combined with the 340 Nm of torque, provides adequate performance for most driving situations. Acceleration from 0 to 100 km/h (0 to 62 mph) takes approximately 12.1 seconds, while 0 to 60 mph is achieved in around 11.5 seconds. The top speed is rated at 210 km/h (130.49 mph).

Compared to the lower-powered diesel variants, the 150 hp engine offers noticeably improved acceleration and overtaking capability. However, it doesn’t deliver the same level of performance as the petrol-powered options. The six-speed manual transmission provides precise gear changes, while the optional EDC automatic offers seamless shifting. The suspension is tuned for comfort, absorbing bumps and providing a stable ride. The steering is light and responsive, making it easy to maneuver in urban environments. The gear ratios are optimized for fuel efficiency, with taller gearing in higher gears to reduce engine speed at cruising speeds.

Equipment & Trim Levels

The Scenic IV 1.7 Blue dCi (150 hp) was typically offered in mid-range trim levels, such as the “Dynamique” or “Signature” variants, depending on the specific market. Standard equipment generally included air conditioning, a touchscreen infotainment system with navigation, Bluetooth connectivity, cruise control, and automatic headlights and wipers. Safety features included ABS, electronic stability control, and multiple airbags.

Interior upholstery was typically cloth, with options for leather or partial leather upgrades. The dashboard featured a modern design with a focus on ergonomics. Optional extras included a panoramic sunroof, a premium sound system, parking sensors, and a rearview camera. The Scenic IV also offered a range of driver assistance systems, such as lane departure warning and automatic emergency braking, which were often available as optional extras or standard on higher trim levels.

Chassis & Braking

The Scenic IV utilizes a MacPherson strut suspension at the front and a multi-link suspension at the rear, providing a comfortable and controlled ride. The chassis is designed to minimize body roll and enhance stability. The front brakes are ventilated discs, while the rear brakes are solid discs. The braking system is assisted by ABS (Anti-lock Braking System) and electronic brakeforce distribution (EBD). The steering system is an electric power steering (EPS) rack and pinion system, providing precise and responsive steering feel. The vehicle rides on 195/55 R20 tires mounted on 20-inch alloy wheels.

Market Reception & Comparison

The Renault Scenic IV 1.7 Blue dCi (150 hp) received generally positive reviews from automotive critics. It was praised for its fuel efficiency, comfortable ride, and spacious interior. However, some critics noted that the performance was not as exhilarating as some of its rivals. Compared to the lower-powered diesel variants, the 150 hp engine offered a significant improvement in performance, making it a more appealing option for drivers who frequently carry passengers or travel long distances. Fuel economy is rated at 4.9 l/100 km (48 US mpg / 57.6 UK mpg), and CO2 emissions are 127 g/km. In terms of reliability, the R9N engine has proven to be generally reliable, although owners should be mindful of maintaining the DPF to prevent clogging.

Technical Specifications

Legacy

The Renault Scenic IV 1.7 Blue dCi (150 hp) remains a popular choice in the used car market, offering a compelling combination of practicality, fuel efficiency, and comfort. The R9N engine, while requiring regular maintenance, has proven to be relatively reliable. The availability of the EDC automatic transmission adds to its appeal. However, potential buyers should be aware of the potential costs associated with DPF maintenance and ensure that the vehicle has been properly serviced. The Scenic IV continues to be recognized as a well-rounded family vehicle, offering a spacious interior and a comfortable driving experience.
