The Renault Master III (Phase II), specifically the 2.3 Energy dCi 170 horsepower panel van in L1H2 SM33 configuration, represents a significant iteration of Renault’s large van offering. Introduced in 2017 and continuing through 2018, this variant was designed to balance performance, fuel efficiency, and cargo capacity for commercial applications. It falls within the broader Master III generation, which underwent a facelift in 2014 (Phase II) bringing updated styling and improved technology. The L1H2 designation refers to the van’s length and roof height, indicating a relatively compact footprint within the Master range, making it suitable for urban deliveries and service applications.

Powertrain & Engine Architecture
The heart of the Master III 2.3 dCi 170 is the M9T engine, a 2.3-liter inline four-cylinder diesel. This engine utilizes a sophisticated twin-turbocharger setup with an intercooler, designed to deliver a broad torque curve and improved responsiveness. The common-rail direct fuel injection system, operating at very high pressures, ensures efficient combustion and reduced emissions. The engine produces 170 horsepower at 3500 rpm and a substantial 380 Nm (280 lb-ft) of torque at just 1500 rpm. This torque output is particularly beneficial for a commercial vehicle, providing strong pulling power and reducing the need for frequent gear changes. The engine is paired with a six-speed manual transmission, chosen for its durability and efficiency in commercial applications. While an automated manual transmission (AMT) was available on some Master III variants, the six-speed manual was the standard offering for this specific configuration.
Driving Characteristics
The 170 horsepower engine and six-speed manual transmission provide a reasonable balance of performance and economy. While not a sports van, the Master III 2.3 dCi offers sufficient power for most delivery and service applications, even when fully loaded. The low-end torque makes it easy to maneuver in urban environments, and the six-speed gearbox allows for comfortable highway cruising. Compared to lower-powered versions of the Master III, such as the 125 hp variant, the 170 hp model offers noticeably improved acceleration and hill-climbing ability. However, it doesn’t match the performance of larger-displacement engines found in some competitor vans. The manual transmission provides the driver with greater control over gear selection, which can be advantageous in varying load conditions and terrain.
Equipment & Trim Levels
The SM33 trim level, as applied to the Master III, typically included standard features geared towards practicality and driver comfort. These generally included air conditioning, a driver’s airbag, electric front windows, and a basic audio system with USB connectivity. The interior was functional and durable, with hard-wearing plastics and cloth upholstery. Optional extras could include a passenger airbag, rear parking sensors, cruise control, and a more advanced infotainment system with navigation. The focus was on providing a comfortable and functional workspace for the driver, rather than luxurious appointments.
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 design with a coil spring and anti-roll bar, providing a reasonable level of ride comfort and handling. The rear suspension utilizes a leaf spring setup, chosen for its robustness and ability to handle heavy loads. The braking system features ventilated discs on the front wheels and solid discs on the rear, providing adequate stopping power for the vehicle’s weight. The 16-inch steel wheels were standard, with larger alloy wheels available as an option.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 was generally well-received in the commercial vehicle market. Critics praised its fuel efficiency, strong torque output, and practical load capacity. Compared to other vans in its class, such as the Fiat Ducato and Mercedes-Benz Sprinter, the Master III offered a competitive combination of features and price. The 170 hp engine provided a good balance between performance and economy, making it a popular choice for businesses that required a reliable and efficient van. However, some reviewers noted that the interior was somewhat basic compared to some competitors.
Legacy
The M9T engine, while generally reliable, is known to require regular maintenance, particularly regarding the turbocharger and fuel injection system. The twin-turbo setup, while enhancing performance, adds complexity and potential failure points. In the used market, the Master III 2.3 dCi 170 remains a popular choice for businesses and individuals seeking a capable and affordable van. Its relatively simple mechanicals (compared to more modern vans with complex emissions systems) make it attractive to those seeking a vehicle that is easier and cheaper to maintain. However, potential buyers should be aware of the importance of regular servicing and should carefully inspect the vehicle for signs of wear and tear.
