Powertrain & Engine Architecture
The heart of the Master III 2.3 Energy dCi (145 hp) is the M9T engine, a 2.3-liter inline four-cylinder diesel. This engine benefits from a twin-turbocharger setup and an intercooler, designed to improve both power and torque delivery. The common-rail direct fuel injection system, a hallmark of modern diesel engines, ensures precise fuel metering for optimal combustion and reduced emissions. The engine produces 145 horsepower at 3500 rpm and a substantial 360 Nm (265.52 lb.-ft.) of torque at just 1500 rpm. This low-end torque is particularly beneficial for a commercial vehicle, providing strong pulling power and effortless acceleration even when heavily loaded. The engine adheres to Euro 6 emission standards, incorporating a particulate filter and Start & Stop system to minimize environmental impact.
Driving Characteristics
The 145 hp engine, paired with a six-speed manual transmission, provides a reasonable balance of performance and economy. While not exceptionally quick, the Master III offers sufficient power for most commercial applications. The readily available torque makes it easy to navigate city streets and maintain highway speeds, even with a full load. The six-speed gearbox allows for efficient cruising and helps to keep engine noise to a minimum. Compared to the lower-powered versions of the Master III, this variant offers a noticeable improvement in responsiveness and overall drivability. However, it doesn’t match the performance of higher-output engines available in the range.
Equipment & Trim Levels
The SL33 trim level, as found in this variant, typically included standard features such as air conditioning, a driver’s airbag, electric front windows, and a basic audio system. The interior is functional and durable, designed to withstand the rigors of commercial use. Upholstery is typically hard-wearing fabric. Optional extras could include a passenger airbag, cruise control, rear parking sensors, and a more advanced infotainment system. The focus of the SL33 trim is practicality and value, providing essential features for a working vehicle.
Chassis & Braking
The Master III utilizes a front-wheel-drive layout. The front suspension employs an independent McPherson strut design with coil springs and an anti-roll bar, providing a comfortable ride and stable handling. The rear suspension features a more traditional leaf spring setup, chosen for its durability and load-carrying capacity. The braking system consists of ventilated discs at the front and solid discs at the rear. The 16-inch wheels are fitted with 215/65 R16 tires, offering a good compromise between comfort and grip.
Market Reception & Comparison
The Renault Master III, in general, was well-received in the European commercial vehicle market. The 2.3 Energy dCi (145 hp) variant was considered a solid all-rounder, offering a good balance of performance, economy, and price. Critics praised its practicality, load capacity, and relatively comfortable driving experience. Compared to the lower-powered versions, the 145 hp engine was seen as a worthwhile upgrade for those who frequently carry heavy loads or travel long distances. Fuel economy figures of 7.0-7.2 l/100 km (33.6 – 32.7 US mpg) were competitive for its class.
Legacy
The M9T engine, while generally reliable, can be susceptible to issues with the turbocharger and fuel injectors if not properly maintained. Regular servicing and the use of high-quality oil are crucial for ensuring longevity. On the used market, the Master III 2.3 Energy dCi (145 hp) remains a popular choice for businesses and tradespeople. Its robust construction, practical design, and relatively affordable running costs make it a sensible option. However, potential buyers should carefully inspect the vehicle’s service history and check for any signs of wear and tear, particularly in the engine and transmission.
