INTRODUCTION
The Renault Master III Phase II 2.3 Energy dCi 170 is a large panel van designed for commercial use. Production of this specific configuration ran from 2017 to 2018. It’s built on Renault’s robust ladder-frame chassis, offering a balance between payload capacity, fuel economy, and driving comfort. The “L2H2” designation signifies a medium-length wheelbase and medium-height roof, making it a popular choice for businesses needing a versatile van without the bulk of the longer or higher variants. This model aimed to provide a practical and efficient solution for delivery services, tradespeople, and businesses requiring a mobile workshop.
Powertrain & Engine Architecture
At the heart of the Master III 2.3 dCi 170 lies the M9T engine, a 2.3-liter inline four-cylinder diesel. This engine utilizes a sophisticated twin-turbocharger system coupled with an intercooler, boosting power output to 170 horsepower at 3500 rpm and 380 Nm (280.27 lb-ft) of torque at a low 1500 rpm. The engine employs a Diesel Commonrail direct fuel injection system, ensuring precise fuel delivery for optimal combustion and reduced emissions. The engine’s architecture is designed for durability and efficiency, meeting Euro 6 emission standards. The 6-speed manual transmission is standard, providing a good balance between fuel economy and drivability. The transmission is geared towards maximizing torque delivery at lower speeds, ideal for carrying heavy loads.
Driving Characteristics
The 170 horsepower 2.3 dCi engine, paired with the 6-speed manual transmission, delivers adequate performance for a large van. While not designed for outright speed, it provides sufficient power for highway cruising and navigating urban environments with a moderate load. The low-end torque is particularly noticeable, making it easy to get the van moving even when fully loaded. Compared to lower-powered versions of the Master III, this variant offers a more relaxed driving experience, especially on inclines or when overtaking. However, it doesn’t possess the same responsiveness as some of its competitors with higher horsepower ratings. The manual transmission allows for greater driver control, but requires more effort than an automatic, particularly in stop-and-go traffic.
Equipment & Trim Levels
The Master III 2.3 dCi 170 L2H2 MM35 typically came equipped with a functional, rather than luxurious, interior. 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 generally offered options such as air conditioning, electric windows, a passenger airbag, and a more advanced audio system with Bluetooth connectivity. Optional extras included rear parking sensors, cruise control, and a navigation system. The interior upholstery was typically hard-wearing fabric, designed to withstand the rigors of commercial use.
Chassis & Braking
The Master III utilizes a robust ladder-frame chassis, providing a solid foundation for carrying heavy loads. The front suspension consists of an independent McPherson strut setup with coil springs and an anti-roll bar, offering a reasonable level of ride comfort. The rear suspension employs a leaf spring design, prioritizing load-carrying capacity over refinement. The braking system features ventilated discs on the front wheels (302x28mm) and solid discs on the rear wheels (305x12mm). ABS (Anti-lock Braking System) is standard. The van’s weight distribution and suspension setup contribute to stable handling, even when fully loaded. The 225/65 R16 tires provide adequate grip in most conditions.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 was generally well-received by critics as a practical and capable work van. It was praised for its fuel efficiency, spacious cargo area, and robust construction. However, some reviewers noted that the interior was somewhat basic compared to some competitors, and the ride quality could be harsh when unladen. Compared to the lower-powered versions of the Master III, the 170 hp variant offered a noticeable improvement in performance, making it a more appealing option for drivers who frequently carry heavy loads or travel long distances. In terms of fuel economy, it offered competitive figures within its class, but was often slightly behind some of the more modern diesel engines offered by Volkswagen and Mercedes-Benz.
Legacy
The Renault Master III 2.3 dCi 170 has proven to be a relatively reliable powertrain in the used car market. 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 fuel injection system. Regular servicing and the use of high-quality oil are crucial for ensuring long-term reliability. Today, these vans are still commonly found in service, testament to their robust construction and practicality. They represent a good value proposition for businesses seeking a dependable and affordable large van, though potential buyers should carefully inspect the vehicle’s maintenance history and overall condition.
