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 SL28 with an automatic transmission, was positioned as a versatile workhorse within the Master lineup, balancing performance, efficiency, and practicality for commercial applications. It falls within the third generation of the Master, which began production in 1997, and the Phase II refresh brought updated styling, improved technology, and enhanced engine options. The L1H1 designation refers to the van’s length and roof height – a shorter wheelbase and lower roof, making it more maneuverable in urban environments while still offering substantial cargo capacity.

Powertrain & Engine Architecture
The heart of this Master variant is the Renault M9T 2.3-liter four-cylinder diesel engine. This engine utilizes a twin-turbocharger setup with an intercooler, a configuration designed to deliver both strong low-end torque and sufficient power for highway cruising. The M9T employs a diesel commonrail direct injection system, contributing to 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 minimizing the need for frequent downshifts. Paired with the engine is a six-speed automatic transmission, offering smoother operation compared to a manual gearbox, especially in stop-and-go traffic. This automatic transmission was a key feature for drivers prioritizing ease of use and reduced driver fatigue.
Driving Characteristics
The 2.3 dCi 170 hp automatic Master offers a comfortable and capable driving experience, particularly suited for urban and regional delivery work. While not a performance-oriented vehicle, the engine’s torque provides brisk acceleration when unladen. The automatic transmission shifts smoothly, although it can sometimes feel hesitant when attempting quick overtaking maneuvers. Compared to the lower-powered 125 hp version, the 170 hp model offers a noticeable improvement in performance, especially when fully loaded. The gear ratios are optimized for fuel efficiency and load-carrying capacity, rather than outright speed. The shorter wheelbase (L1) contributes to improved maneuverability in tight spaces, a significant advantage in urban environments.
Equipment & Trim Levels
The SL28 trim level, as featured in this variant, typically included standard features such as air conditioning, a driver’s airbag, electric front windows, and a basic audio system with USB connectivity. Optional extras often included a passenger airbag, rear parking sensors, cruise control, and a more advanced infotainment system with navigation. Interior upholstery was typically durable cloth, designed to withstand the rigors of commercial use. The dashboard layout was functional and straightforward, prioritizing practicality over aesthetic flair. The focus was on providing a comfortable and ergonomic workspace for the driver.
Chassis & Braking
The Renault Master III utilizes a front-wheel-drive layout, contributing to a lower load floor and improved space utilization within the cargo area. The front suspension employs an independent McPherson strut design with coil springs and an 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 load-carrying capacity. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The braking system is adequate for the vehicle’s weight and intended use, but it lacks the stopping power of more sophisticated systems found in passenger cars.
Market Reception & Comparison
The Renault Master III, and specifically the 2.3 dCi 170 hp automatic variant, was generally well-received by commercial vehicle operators. Critics praised its fuel efficiency, load-carrying capacity, and comfortable driving experience. Compared to competitors like the Fiat Ducato and Mercedes-Benz Sprinter, the Master offered a competitive price point and a good balance of features. The automatic transmission was a popular option, particularly among drivers who spent a significant amount of time in congested traffic. However, some reviewers noted that the interior trim quality was not as refined as some of its rivals.
Legacy
The Renault Master III, including the 2.3 dCi 170 hp automatic version, has proven to be a reliable and durable workhorse. The M9T engine, while not without its occasional issues (such as turbocharger wear), is generally considered to be a robust and long-lasting unit when properly maintained. On the used market, these vans remain popular due to their affordability and practicality. Regular maintenance, including oil changes and timely replacement of wear items, is crucial to ensuring the longevity of this powertrain. The combination of a capable engine, a smooth-shifting automatic transmission, and a spacious cargo area continues to make the Renault Master III a viable option for businesses and tradespeople seeking a dependable commercial vehicle.
