The Renault Scenic IV Phase I 1.7 Blue dCi (150 hp) EDC, produced from September 2018 to October 2020, represents a mid-range offering within the fourth generation of Renault’s popular compact minivan. Positioned between the lower-powered diesel variants and the petrol-powered options, this version aimed to balance fuel efficiency with respectable performance and a more refined driving experience thanks to its dual-clutch transmission. The Scenic IV (Phase I) utilizes the Common Module Family (CMF) C/D platform, shared with other Renault-Nissan-Mitsubishi Alliance vehicles, offering a modern and versatile platform for a family vehicle.
Powertrain & Engine Architecture
At the heart of the Scenic IV 1.7 Blue dCi EDC lies the Renault R9N engine, a 1.7-liter inline four-cylinder diesel engine. This engine is a member of Renault’s Blue dCi family, incorporating advanced technologies to meet stringent Euro 6 emissions standards. The R9N engine features a common rail direct fuel injection system, operating at a maximum pressure of 2,000 bar, ensuring precise fuel delivery and optimized combustion. A turbocharger with an intercooler is employed to boost power and torque, delivering 150 hp at 3500 rpm and 340 Nm (250.77 lb-ft) of torque at 1750 rpm. The engine utilizes four valves per cylinder and is constructed with a cast iron block and aluminum cylinder head.
The “EDC” designation refers to Renault’s Efficient Dual Clutch automatic transmission. This six-speed dual-clutch transmission provides quick and smooth gear changes, contributing to improved fuel economy and a more engaging driving experience compared to a traditional torque-converter automatic. The EDC transmission is electronically controlled, adapting shift points based on driving conditions and driver input. The transmission is a wet-clutch design, offering improved durability and heat dissipation.
Engine Specifications
The R9N engine incorporates a diesel particulate filter (DPF) to reduce particulate matter emissions, a crucial component for meeting Euro 6 regulations. Engine oil capacity is 5.9 liters (6.23 US qt / 5.19 UK qt), and the recommended oil specification should be consulted in the vehicle’s owner’s manual. The cooling system requires 7 liters (7.4 US qt / 6.16 UK qt) of coolant.
Driving Characteristics
The 150 hp 1.7 Blue dCi EDC powertrain delivers a comfortable and capable driving experience in the Scenic IV. While not a performance-oriented setup, the engine provides sufficient power for everyday driving, including highway cruising and overtaking maneuvers. The EDC transmission contributes to brisk acceleration, particularly in the lower gears. The weight-to-power ratio of 11.4 kg/hp and weight-to-torque ratio of 5 kg/Nm reflect a balanced performance profile.
Compared to lower-powered diesel variants, the 150 hp version offers noticeably more responsive acceleration. However, it doesn’t match the outright performance of the petrol-powered engines. The EDC transmission’s quick shifts help to mask the inherent limitations of the diesel engine’s relatively narrow power band. The transmission’s programming prioritizes fuel efficiency, resulting in relatively high gear ratios in the upper gears, which aids in highway fuel economy but can sometimes feel slightly strained during aggressive acceleration.
Equipment & Trim Levels
The Scenic IV 1.7 Blue dCi (150 hp) EDC was typically offered in mid-range trim levels, such as the “Intens” or equivalent, depending on the specific market. Standard equipment generally included features like air conditioning, a touchscreen infotainment system with navigation, Bluetooth connectivity, cruise control, and automatic headlights and wipers. Interior upholstery was typically cloth, with options for leather upgrades. The dashboard layout featured a modern design with a focus on ergonomics and user-friendliness.
Optional extras commonly available for this trim included a panoramic sunroof, a hands-free parking assist system, a premium audio system, and advanced driver-assistance systems (ADAS) such as lane departure warning, blind spot monitoring, and automatic emergency braking. The Scenic IV offered a spacious and versatile interior, with a modular seating system allowing for various configurations to maximize cargo space.
Chassis & Braking
The Scenic IV utilizes a MacPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride and good handling characteristics. The suspension is tuned to prioritize comfort, absorbing bumps and imperfections in the road surface effectively. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The front brakes are ventilated discs, while the rear brakes are solid discs, providing adequate stopping power for the vehicle’s weight. The steering system is an electric power-assisted rack and pinion system, offering light and precise steering feel. The vehicle is equipped with ABS (Anti-lock Braking System) as standard.
The standard tire size is 195/55 R20, mounted on 20-inch alloy wheels. The curb weight of 1710 kg (3769.9 lbs) is typical for a compact minivan in this class.
Market Reception & Comparison
The Renault Scenic IV 1.7 Blue dCi (150 hp) EDC received generally positive reviews from automotive critics. It was praised for its comfortable ride, spacious interior, and fuel efficiency. The EDC transmission was also well-regarded for its smooth and quick gear changes. However, some critics noted that the engine could feel slightly underpowered when fully loaded or driving uphill.
Compared to other trims in the Scenic IV lineup, the 1.7 Blue dCi EDC offered a good balance between performance and fuel economy. The lower-powered diesel variants were more fuel-efficient but lacked the same level of responsiveness. The petrol-powered engines offered more performance but typically consumed more fuel. In terms of reliability, the R9N engine and EDC transmission have proven to be generally reliable, although regular maintenance is essential to prevent issues with the DPF and transmission components.
