Renault Scenic IV (Phase I) 1.7 Blue dCi (120 Hp)

The Renault Scenic IV Phase I 1.7 Blue dCi (120 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 and practicality. It was positioned below the more powerful gasoline engines and above the base-level trims, targeting families and individuals seeking a versatile and economical vehicle. The Scenic IV, built on the Common Module Family (CMF) C/D platform, represented Renault’s fourth generation of the Scenic, aiming to modernize the minivan segment with a more crossover-inspired design and enhanced technology.

Powertrain & Engine Architecture

The heart of the Scenic IV 1.7 Blue dCi is the Renault R9N engine, a 1.7-liter inline four-cylinder diesel engine. This engine is a member of Renault’s Blue dCi family, known for its focus on reducing emissions and improving fuel economy. The R9N utilizes a common rail direct fuel injection system, operating at a maximum pressure of 1,800 bar, ensuring precise fuel delivery and efficient combustion. The engine also features a turbocharger with an intercooler, boosting power output and improving responsiveness. The valvetrain consists of four valves per cylinder (DOHC), contributing to optimized gas flow and enhanced performance.

This specific variant was exclusively offered with a 6-speed manual transmission, driving the front wheels. The transmission was chosen to maximize fuel efficiency and provide a more engaging driving experience compared to an automatic option, which was not available with this engine. The gear ratios were tuned to prioritize fuel economy at cruising speeds while still providing adequate acceleration for everyday driving.

Engine Specifications

The R9N engine in this configuration produces 120 horsepower (hp) at 3,500 rpm and 300 Newton-meters (221.27 lb-ft) of torque at 1,750 rpm. This torque output, available at relatively low engine speeds, provides good pulling power for overtaking and carrying passengers or cargo. The engine’s power-to-weight ratio is approximately 76.8 hp per tonne, and the torque-to-weight ratio is 192.1 Nm per tonne, reflecting the vehicle’s moderate performance capabilities.

Driving Characteristics

The Renault Scenic IV 1.7 Blue dCi (120 hp) delivers a comfortable and refined driving experience, prioritizing fuel efficiency over outright performance. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 14.2 seconds, while 0 to 60 mph is achieved in around 13.5 seconds. The top speed is rated at 195 km/h (121.17 mph). While not particularly sporty, the engine provides sufficient power for everyday driving situations, including highway cruising and city commuting. The 6-speed manual transmission allows for precise gear selection and driver control. The engine is relatively quiet and smooth, with minimal vibration, contributing to a pleasant cabin environment. Compared to the higher-powered gasoline variants, the 1.7 Blue dCi offers significantly better fuel economy but lacks the same level of acceleration and responsiveness. Compared to other diesel variants, the 120 hp version offered a good balance between power and economy, making it a popular choice for those prioritizing running costs.

Equipment & Trim Levels

The Scenic IV 1.7 Blue dCi (120 hp) typically came equipped with a range of standard features, including air conditioning, a touchscreen infotainment system with Bluetooth connectivity, cruise control, and electric windows. Safety features included ABS, electronic stability control, and multiple airbags. Interior upholstery was typically cloth, with options for higher-grade materials available on higher trim levels. The dashboard layout was modern and functional, with a focus on ergonomics and ease of use.

Optional extras included a panoramic sunroof, leather upholstery, a navigation system, a rear parking camera, and advanced driver-assistance systems such as automatic emergency braking and lane departure warning. Trim levels varied depending on the market, but generally included options like “Life,” “Zen,” and “Intens,” with each successive trim adding more features and luxury appointments.

Chassis & Braking

The Scenic IV 1.7 Blue dCi (120 hp) features a MacPherson strut front suspension and a semi-independent twist beam rear suspension. This suspension setup provides a comfortable ride quality, absorbing bumps and irregularities in the road surface effectively. The front brakes are ventilated discs, providing ample stopping power, while the rear brakes are solid discs. The steering is electric power-assisted, offering light and precise steering feel. The vehicle rides on 195/55 R20 tires, mounted on 20-inch alloy wheels. The curb weight of the vehicle is 1,562 kg (3,443.62 lbs), and the maximum permissible weight is 2,170 kg (4,784.03 lbs).

Market Reception & Comparison

The Renault Scenic IV 1.7 Blue dCi (120 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 engine lacked the punch of the gasoline variants and that the acceleration was somewhat sluggish. In terms of fuel economy, the 1.7 Blue dCi achieves approximately 4.9 l/100 km (48 US mpg, 57.6 UK mpg), making it one of the most economical options in the Scenic IV lineup. Reliability reports suggest that the R9N engine is generally reliable, although regular maintenance is essential to prevent issues with the diesel particulate filter (DPF) and fuel injection system. Compared to the 1.3 TCe gasoline engine, the 1.7 Blue dCi offered superior fuel economy but lower performance. Compared to the more powerful dCi variants, it provided a more affordable entry point into the Scenic IV range.

Technical Specifications

Legacy

The Renault Scenic IV 1.7 Blue dCi (120 hp) remains a popular choice in the used car market, particularly for buyers seeking a fuel-efficient and practical family vehicle. The R9N engine, while requiring regular maintenance, has proven to be relatively durable.
