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. Positioned as a mid-range option within the Master III lineup, this configuration – designated L1H2 SM35 with an automatic transmission – catered to businesses and tradespeople requiring a balance of performance, efficiency, and practicality. The Phase II update brought styling revisions and, crucially, powertrain refinements to meet increasingly stringent Euro 6 emissions standards. This model is primarily a commercial vehicle, designed for the European market, but increasingly seen as a base for campervan conversions and specialized mobile workshops.

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 low-end torque for hauling and sufficient power for highway cruising. The M9T employs a diesel commonrail direct injection system, ensuring precise fuel delivery and contributing to improved combustion efficiency 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. Paired with this engine is a six-speed automatic transmission, offering smoother operation compared to manual options, particularly in stop-and-go traffic. This automatic transmission, while improving driver comfort, does slightly impact fuel economy compared to the manual counterpart.
Driving Characteristics
The 170 hp automatic Master offers a competent, if not particularly exciting, driving experience. The readily available torque from the M9T engine makes it well-suited for carrying heavy loads. Acceleration is adequate, but the automatic transmission can sometimes feel hesitant when downshifting for overtaking maneuvers. The gear ratios are tuned for efficiency rather than outright performance. Compared to the lower-powered 125 hp versions, this variant provides a noticeable improvement in responsiveness, especially when fully loaded. However, it doesn’t match the performance of the higher-output 180 hp engine, which offers a more spirited driving experience. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen.
Equipment & Trim Levels
The L1H2 SM35 trim level typically included standard features such as air conditioning, a driver’s airbag, electric front windows, and a basic audio system with USB connectivity. The interior is functional and durable, prioritizing practicality over luxury. Upholstery is typically hard-wearing fabric. Optional extras included features like a passenger airbag, rear parking sensors, cruise control, and a more advanced infotainment system with navigation. The SM35 designation indicates a specific body length and roof height combination, offering a good balance between cargo volume and maneuverability.
Chassis & Braking
The Renault Master III utilizes a front-wheel-drive layout. The front suspension consists of independent McPherson struts with a coil spring and anti-roll bar, providing reasonable handling and ride comfort. The rear suspension employs 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. The braking system is adequate for the vehicle’s weight, but drivers should allow for increased stopping distances when fully loaded. The 16-inch steel wheels are standard, with alloy wheels available as an optional upgrade.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 hp automatic was generally well-received by commercial vehicle operators. Critics praised its fuel efficiency, load-carrying capacity, and relatively comfortable driving experience. Compared to competitors like the Fiat Ducato and Mercedes-Benz Sprinter, the Master offered a competitive price point and a good level of standard equipment. The automatic transmission was seen as a significant benefit for urban delivery drivers. However, some reviewers noted the somewhat basic interior and the firm ride quality when unladen. Fuel economy figures of 7.2-7.3 l/100km (around 32 mpg) were considered respectable for a vehicle of this size and weight.
Legacy
The Renault Master III 2.3 dCi 170 hp automatic has proven to be a relatively reliable powertrain. The M9T engine, while complex with its twin-turbo setup, is generally durable if properly maintained. Common issues include turbocharger wear and potential problems with the diesel particulate filter (DPF), particularly on vehicles used primarily for short journeys. In the used market, these vans represent good value for money, offering a practical and capable solution for businesses and tradespeople. The availability of spare parts is good, and the relatively simple mechanical design makes them relatively easy to repair. The Master III continues to be a popular choice for campervan conversions, demonstrating its versatility and enduring appeal.
