The Renault Koleos II Phase II 1.7 Blue dCi (150 hp) X-Tronic, produced from September 2019 to November 2020, represents a mid-cycle refresh of Renault’s D-segment SUV. Positioned as a practical and comfortable family vehicle, this variant aimed to offer a balance between fuel efficiency and reasonable performance within the Koleos lineup. It primarily targeted European markets where diesel engines remained popular, offering a more economical alternative to gasoline-powered options. The Koleos II, built upon the Common Module Family (CMF) platform shared with Nissan, sought to provide a more premium experience than Renault’s smaller crossover offerings, competing with vehicles like the Peugeot 5008 and Hyundai Santa Fe.

Powertrain & Engine Architecture
The heart of this Koleos variant is the Renault R9N A4 1.7-liter four-cylinder diesel engine. This engine belongs to the ‘Blue dCi’ family, incorporating technologies aimed at reducing emissions and improving efficiency. It features a turbocharger with variable geometry, an intercooler, and a common-rail direct fuel injection system operating at pressures up to 1800 bar. The engine utilizes four valves per cylinder and a timing chain for durability. The X-Tronic CVT (Continuously Variable Transmission) is paired with this engine. Unlike traditional automatic transmissions with fixed gear ratios, the X-Tronic utilizes a belt and pulley system to provide a seamless and stepless gear change, optimizing engine efficiency and providing smooth acceleration.
Driving Characteristics
The 150 hp and 340 Nm of torque offered by this engine configuration provide adequate, but not exhilarating, performance. Acceleration from 0-60 mph takes around 11.2 seconds, making it suitable for everyday driving and highway cruising. The X-Tronic transmission, while smooth, can sometimes feel less responsive than a traditional automatic or manual gearbox, particularly during quick overtaking maneuvers. The CVT tends to hold the engine at a constant RPM during acceleration, which can result in a droning sound. Compared to the higher-output 177 hp diesel variant, this version offers slightly less power but prioritizes fuel economy. It also differs significantly from the gasoline-powered Koleos models, which generally offer more immediate throttle response but consume more fuel.
Equipment & Trim Levels
The 1.7 Blue dCi X-Tronic typically came equipped with a respectable level of standard features. These included automatic climate control, a 7-inch touchscreen infotainment system with navigation, Bluetooth connectivity, rear parking sensors, and cruise control. Higher trim levels added features like leather upholstery, a panoramic sunroof, a hands-free power tailgate, and advanced driver-assistance systems (ADAS) such as blind-spot monitoring and automatic emergency braking. Interior upholstery was generally cloth on base models, with leather options available on higher trims. Dashboard materials were of a decent quality, aiming for a more premium feel than Renault’s lower-priced models.
Chassis & Braking
The Koleos II utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear, providing a comfortable ride quality. The suspension tuning is geared towards absorbing bumps and providing stability, rather than sporty handling. Front brakes are ventilated discs measuring 320mm, while rear brakes are solid discs measuring 292mm. Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) are standard safety features. The Koleos’s weight of approximately 1683 kg (3710.38 lbs) necessitates a robust braking system to ensure adequate stopping power.
Market Reception & Comparison
The Renault Koleos II 1.7 Blue dCi X-Tronic was generally well-received by automotive critics as a practical and comfortable family SUV. The diesel engine was praised for its fuel efficiency, achieving between 37.9 and 38.6 US mpg on the combined cycle. However, the X-Tronic CVT transmission received mixed reviews, with some testers finding it less engaging than traditional automatic gearboxes. Compared to competitors like the Peugeot 5008 and Hyundai Santa Fe, the Koleos offered a competitive level of equipment and a comfortable ride, but its styling was sometimes considered less distinctive.
Legacy
The R9N engine family, including the 1.7 Blue dCi, has proven to be relatively reliable, although diesel particulate filter (DPF) issues can occur, particularly with vehicles primarily used for short journeys. The X-Tronic CVT transmission, if properly maintained with regular fluid changes, is generally durable. On the used car market, the Koleos II 1.7 Blue dCi X-Tronic represents a good value proposition for buyers seeking a spacious and economical family SUV. Its fuel efficiency and comfortable ride make it a suitable choice for long-distance travel, while its practical interior and decent equipment levels cater to the needs of modern families.
