The Renault Master III (Phase II), specifically the 2.3 dCi 170 horsepower variant introduced in 2017 and produced through 2018, represents a significant iteration of Renault’s large van offering. This version, designated L1H1 SL33 and equipped with a six-speed automatic transmission, was aimed at commercial users requiring a balance of performance, efficiency, and convenience. It falls within the broader Master III generation (launched in 2010 and facelifted in 2014), which served as Renault’s primary competitor in the large van segment alongside models like the Fiat Ducato, Mercedes-Benz Sprinter, and Ford Transit. The Phase II updates brought revised styling, improved interior appointments, and crucially, updated engine technology to meet stricter Euro 6 emissions standards.

Powertrain & Engine Architecture
The heart of this Master variant is the Renault M9T 2.3-liter four-cylinder diesel engine. This engine, a key component of Renault’s dCi range, utilizes a twin-turbocharger setup with an intercooler to deliver 170 horsepower at 3500 rpm and a substantial 380 Nm (280 lb-ft) of torque from as low as 1500 rpm. The engine employs a diesel common rail direct injection system, ensuring precise fuel delivery for optimized combustion and reduced emissions. The M9T engine is known for its relatively robust construction, though it does require adherence to recommended service intervals to maintain reliability. The six-speed automatic transmission, sourced from ZF, provides smooth gear changes and contributes to driver comfort, particularly in urban environments. This transmission was chosen for its durability and ability to handle the engine’s torque output.
Driving Characteristics
The 170 horsepower and automatic transmission combination in the Master L1H1 SL33 offers a noticeable step up in performance compared to lower-powered versions. While not a sports van, it provides ample power for fully loaded operation and highway cruising. The automatic transmission, while convenient, does slightly diminish the responsiveness compared to a manual gearbox. Gear ratios are tuned for fuel efficiency and load-carrying capability, prioritizing torque delivery over outright acceleration. In real-world conditions, the van feels stable and predictable, with the automatic transmission managing gear changes effectively. The relatively long wheelbase contributes to a comfortable ride, even on uneven surfaces.
Equipment & Trim Levels
The SL33 trim level represents a mid-range offering within the Master III lineup. Standard equipment typically included air conditioning, a driver’s airbag, electric windows, central locking, and a basic audio system with USB connectivity. The interior features durable, utilitarian materials designed for commercial use. Optional extras available for this trim included a passenger airbag, cruise control, rear parking sensors, and upgraded infotainment systems with navigation. The dashboard layout is functional and driver-focused, with clearly labeled controls.
Chassis & Braking
The Master III utilizes a front-wheel-drive layout, contributing to a lower load floor and improved space utilization. The front suspension employs an independent McPherson strut setup with a coil spring and anti-roll bar, providing a comfortable ride and predictable handling. The rear suspension utilizes a leaf spring design, chosen for its load-carrying capacity and durability. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The braking system is adequate for the van’s weight and performance, but it’s not particularly sporty. The 225/65 R16 tires provide a good balance of grip and rolling resistance.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 Automatic was generally well-received by critics as a practical and capable large van. It was praised for its comfortable ride, spacious interior, and relatively refined engine. However, some reviewers noted that the automatic transmission could feel slightly sluggish at times, and the interior materials were not as premium as some competitors. Compared to the lower-powered 125 hp version, the 170 hp variant offered a significant improvement in performance, making it more suitable for long-distance driving and heavy loads. Fuel economy was competitive within the segment, averaging around 32-33 mpg in combined driving.
Legacy
The Renault Master III, and specifically the 2.3 dCi 170 Automatic variant, has proven to be a relatively reliable workhorse in the used vehicle market. The M9T engine, when properly maintained, can accumulate high mileage without major issues. Common maintenance items include regular oil changes, filter replacements, and attention to the turbocharger system. The ZF automatic transmission is also known for its durability. However, potential buyers should be aware of potential issues with the diesel particulate filter (DPF) and the fuel injection system. Overall, the Master III remains a popular choice for businesses and tradespeople seeking a dependable and spacious large van.
