The Renault Master III Phase II, produced from 2017 to 2018, represents a significant iteration of Renault’s large van platform, designed primarily for commercial use in Europe. This variant, specifically the 2.3 Energy dCi (145 hp) L1H1 SL35 panel van, occupied a middle ground within the Master III lineup, offering a balance between performance, fuel efficiency, and payload capacity. 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. The SL35 trim level denoted a specific equipment package geared towards professional tradespeople and delivery services. This model was a key player in the competitive large van segment, facing rivals like the Fiat Ducato, Mercedes-Benz Sprinter, and Ford Transit.

Powertrain & Engine Architecture
The heart of the Master III 2.3 dCi 145 is the M9T engine, a 2.3-liter inline-four cylinder diesel. This engine is a product of Renault’s Energy dCi range, emphasizing efficiency and reduced emissions. The M9T utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A key feature is its twin-turbocharger setup. The smaller turbocharger provides quick response at low engine speeds, minimizing turbo lag, while the larger turbocharger delivers increased power at higher RPMs. An intercooler further enhances performance by cooling the compressed intake air. The engine produces 145 horsepower at 3500 rpm and 360 Nm (265.52 lb-ft) of torque at 1500 rpm. This configuration was paired with a six-speed manual transmission, chosen for its durability and fuel efficiency in commercial applications. While an automated manual transmission (AMT) was available on some Master III models, the 145 hp version was predominantly offered with the manual gearbox.
Driving Characteristics
The 145 hp 2.3 dCi engine, coupled with the six-speed manual transmission, provided a reasonable balance of performance and economy for the Renault Master. Acceleration was adequate for typical commercial use, but it wasn’t designed for rapid speed. The engine’s strong low-end torque made it well-suited for hauling loads and navigating urban traffic. The gear ratios were optimized for fuel efficiency, with a relatively tall sixth gear for highway cruising. Compared to the higher-output 170 hp version of the 2.3 dCi, the 145 hp model felt less strained when fully loaded, potentially contributing to improved long-term reliability. However, it lacked the extra power for quicker overtaking maneuvers or driving on steep inclines. The manual transmission offered precise control, but required more driver involvement than an automatic.
Equipment & Trim Levels
The SL35 trim level represented a mid-range offering in the Master III lineup. Standard equipment included air conditioning, a driver’s airbag, electric front windows, and a basic audio system with USB connectivity. The SL35 also featured a load area lined with protective panels and a reinforced bulkhead separating the cab from the cargo area. Optional extras included a passenger airbag, rear parking sensors, a navigation system, and cruise control. Interior upholstery was typically durable cloth, designed to withstand the rigors of commercial use. The dashboard layout was functional and straightforward, prioritizing practicality over aesthetics.
Chassis & Braking
The Renault Master III utilized a front-wheel-drive layout, contributing to a lower load floor and improved space utilization. The front suspension consisted of independent McPherson struts with coil springs and an anti-roll bar, providing a comfortable ride and predictable handling. The rear suspension employed a leaf spring setup, chosen for its robustness and load-carrying capacity. The braking system featured ventilated discs on the front wheels and solid discs on the rear. Anti-lock Braking System (ABS) was standard. The steering was hydraulic power-assisted, offering a reasonable level of assistance without feeling overly light or disconnected.
Market Reception & Comparison
The Renault Master III 2.3 dCi 145 was generally well-received by critics as a practical and reliable workhorse. Its fuel economy was competitive within the large van segment, and the M9T engine proved to be durable and relatively easy to maintain. Compared to the 170 hp version, the 145 hp model offered a slightly lower purchase price and potentially better long-term reliability. However, some reviewers noted that the engine could feel underpowered when fully loaded or driving on hilly terrain. The Master’s spacious interior and versatile load area were consistently praised. In terms of reliability, the M9T engine had a generally good reputation, although some owners reported issues with the turbocharger and fuel injectors over time.
Legacy
The Renault Master III 2.3 dCi 145 remains a common sight on European roads today, testament to its durability and practicality. On the used car market, these vans represent a relatively affordable option for businesses and tradespeople. The M9T engine, while not without its potential issues, is generally considered to be a robust and reliable unit when properly maintained. Parts availability is good, and repair costs are typically reasonable. The Master III’s simple construction and straightforward design make it a relatively easy vehicle to work on for experienced mechanics. While newer vans offer more advanced technology and features, the Master III 2.3 dCi 145 continues to provide a dependable and cost-effective solution for commercial transport needs.
