The Renault Master III (Phase II), specifically the 2.3 dCi 170 horsepower variant with the automatic transmission (designated MM33), represents a significant iteration in Renault’s large van lineup. Introduced in 2017 and continuing through 2018, this configuration was aimed at commercial users requiring a balance of performance, efficiency, and convenience. The Master III, built on the X62 platform, served as Renault’s primary competitor in the large van segment, battling models like the Fiat Ducato, Mercedes-Benz Sprinter, and Ford Transit. The L2H2 designation indicates a medium wheelbase and medium roof height, offering a versatile cargo capacity for a wide range of applications. This particular version, with its automatic transmission, was positioned as a step up from the base manual transmission models, appealing to drivers prioritizing ease of use, especially in urban environments.

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, designed to deliver a broad torque curve and improved responsiveness. The M9T engine is a direct-injection diesel, employing Common Rail technology for precise fuel delivery. This system allows for multiple injections per combustion cycle, optimizing efficiency and reducing 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 effortless acceleration even when heavily loaded. The automatic transmission is a six-speed unit, chosen for its smooth operation and ease of use, particularly in stop-and-go traffic. While not known for being the fastest-shifting automatic, it prioritizes durability and reliability.
Driving Characteristics
The 170 horsepower and automatic transmission combination delivers a competent, if not exhilarating, driving experience. Acceleration is adequate for most situations, but the van’s weight is always noticeable. The automatic transmission is programmed for efficiency, meaning it upshifts quickly to maintain fuel economy. This can sometimes result in the engine feeling slightly strained when climbing hills or accelerating with a full load. Compared to the manual transmission versions, the automatic offers a more relaxed driving experience, especially in urban environments. However, the manual versions generally provide slightly better fuel economy and a more direct connection to the engine. The gear ratios are tuned for maximizing torque at lower speeds, making it well-suited for hauling and towing.
Equipment & Trim Levels
The Master III Phase II, in this 2.3 dCi 170 Automatic configuration, typically came with a reasonable level of standard equipment. This included features like air conditioning, a driver’s airbag, electric windows, and a basic audio system with USB connectivity. Higher trim levels, often denoted by additional package options, could add features like rear parking sensors, cruise control, a more advanced infotainment system with navigation, and upgraded interior trim. The interior generally featured durable, utilitarian materials designed to withstand the rigors of commercial use. Upholstery was typically cloth, and the dashboard layout was functional and straightforward.
Chassis & Braking
The Master III utilizes a front-wheel-drive layout, contributing to a lower load floor and improved space utilization. The front suspension consists of independent McPherson struts with a coil spring and anti-roll bar, providing a comfortable ride and decent handling. The rear suspension employs 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. While adequate for most applications, the braking system isn’t particularly sporty. The van’s relatively high center of gravity and weight necessitate a cautious driving style, especially when cornering.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 Automatic was generally well-received by critics as a practical and capable workhorse. Its fuel economy, averaging around 32 mpg combined, was competitive within the large van segment. However, some reviewers noted that the automatic transmission could feel sluggish at times, and the interior lacked the refinement of some competitors. Compared to the lower-powered 1.9 dCi versions, the 2.3 dCi offered a significant performance boost, making it a better choice for those regularly carrying heavy loads or traveling long distances. Compared to the more expensive Mercedes-Benz Sprinter, the Master offered a more affordable option with comparable functionality.
Legacy
The Renault Master III, including the 2.3 dCi 170 Automatic variant, has proven to be a relatively reliable workhorse in the used vehicle market. The M9T engine, while not without its potential issues (such as turbocharger wear and injector problems), is generally durable if properly maintained. The automatic transmission, while not the most sophisticated, has also proven to be reasonably reliable. Today, these vans are readily available on the used market at affordable prices, making them a popular choice for small businesses and tradespeople. Regular maintenance, including oil changes and filter replacements, is crucial for ensuring the longevity of this powertrain.
