The Renault Master III (Phase II), specifically the 2.3 Energy dCi 145 horsepower panel van in L3H3 LH35 configuration, represents a significant iteration of Renault’s large van offering. Introduced in 2017 and continuing through 2018, this variant was positioned as a workhorse solution for businesses requiring substantial cargo capacity and reasonable fuel efficiency. It falls within the third generation of the Master, which began production in 1997, and the Phase II update brought refinements to the engine lineup and overall vehicle presentation. The L3H3 designation indicates a long wheelbase and high roof, maximizing interior volume. This model primarily served the European commercial vehicle market, competing with offerings from Fiat, Mercedes-Benz, and Volkswagen.

Powertrain & Engine Architecture
The heart of this Master variant is the Renault M9T 2.3-liter four-cylinder diesel engine. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The M9T is notable for its twin-turbocharger setup, employing a small turbo for rapid response at low engine speeds and a larger turbo to maintain power at higher RPMs. An intercooler is included to cool the compressed intake air, further enhancing performance and efficiency. The engine produces 145 horsepower at 3500 rpm and a substantial 360 Nm (265.52 lb.-ft.) of torque at just 1500 rpm. This torque output is particularly beneficial for a commercial vehicle, providing strong pulling power and effortless acceleration even when heavily loaded. 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 models, the six-speed manual was a common choice for this power output.
Driving Characteristics
The 145 hp 2.3 dCi engine, coupled with the six-speed manual transmission, provides a balanced driving experience. While not exceptionally quick, the Master L3H3 LH35 offers sufficient power for most commercial tasks. The readily available torque allows for smooth acceleration, even with a full load. The gear ratios are well-chosen to maximize fuel efficiency and provide adequate pulling power. Compared to lower-powered versions of the Master, this variant offers a noticeable improvement in performance, particularly when climbing hills or overtaking. However, it doesn’t match the responsiveness of higher-output engines available in the Master range. The suspension, tuned for carrying heavy loads, provides a comfortable ride when unladen but can feel somewhat firm when fully loaded. Steering is precise but lacks significant feedback.
Equipment & Trim Levels
The Master III Phase II L3H3 LH35 2.3 dCi typically came with a functional, rather than luxurious, equipment list. Standard features included a driver’s airbag, ABS brakes, power steering, and a basic audio system. The cabin is designed for practicality, with durable materials and a focus on ergonomics. Trim levels varied depending on the market, but common options included air conditioning, electric windows, a passenger airbag, and a rear parking sensor. The interior upholstery was typically hard-wearing fabric. Optional extras could include navigation systems, upgraded audio systems, and various cargo area configurations.
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 coil springs and an anti-roll bar, providing a good balance of comfort and handling. The rear suspension utilizes a robust leaf spring setup, designed to handle heavy loads. Braking is handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard. The chassis is reinforced to withstand the stresses of commercial use, and the vehicle’s weight distribution is optimized for stability.
Market Reception & Comparison
The Renault Master III 2.3 dCi 145 hp variant was generally well-received by commercial vehicle operators. Critics praised its fuel efficiency, load capacity, and robust construction. Compared to the lower-powered 125 hp version, the 145 hp model offered a significant performance upgrade, making it more suitable for long-distance driving and heavier loads. However, it was often seen as a compromise between the more affordable 125 hp model and the more powerful (and expensive) 165 hp variant. Fuel economy was competitive within its class, and the Euro 6 emissions compliance was a key selling point. Reliability was generally good, although some owners reported issues with the diesel particulate filter (DPF) system, a common concern with modern diesel engines.
Legacy
The Renault Master III 2.3 Energy dCi 145 hp remains a common sight on European roads today. The M9T engine, while not without its quirks, has proven to be relatively durable when properly maintained. Used examples are readily available and generally offer good value for money. The L3H3 LH35 configuration is particularly sought after for its exceptional cargo capacity. The vehicle’s robust construction and relatively simple mechanicals make it a popular choice for businesses and tradespeople seeking a reliable and practical van. However, potential buyers should be aware of the potential for DPF issues and ensure that the vehicle has been regularly serviced.
