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 strong low-end torque and sustained power at higher RPMs. The common rail direct fuel injection system, operating at very high pressures, ensures efficient combustion and contributes to the engine’s relatively clean emissions, meeting Euro 6 standards. 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 ample pulling power and reducing the need for frequent downshifts. The automatic transmission is a six-speed unit, chosen for its ease of use and suitability for urban driving conditions. While not known for being the fastest shifting transmission, it prioritizes smoothness and reliability.
Driving Characteristics
The 170 horsepower 2.3 dCi automatic Master offers a comfortable and capable driving experience, particularly when compared to lower-powered versions. The automatic transmission, while not sporty, provides smooth gear changes and makes navigating city traffic less demanding. The readily available torque means that the van can accelerate briskly even when fully loaded. However, it’s important to note that this isn’t a performance-oriented vehicle; the focus is on practicality and efficiency. Compared to a manual transmission version, the automatic offers less driver engagement but greater convenience. Against higher-output versions of the Master, the 170 hp model provides a good balance between performance and fuel economy, making it a sensible choice for many operators.
Equipment & Trim Levels
The L1H1 SL35 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, designed to withstand the rigors of commercial use. Optional extras often included a passenger airbag, rear parking sensors, cruise control, and upgraded infotainment systems with navigation. The SL35 designation indicates a mid-range trim, offering a step up in comfort and convenience compared to the base models but falling short of the more luxurious and fully-equipped versions.
Chassis & Braking
The Renault 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 a coil spring and anti-roll bar, providing a reasonable level of ride comfort and handling. The rear suspension utilizes a more traditional leaf spring setup, chosen for its robustness and load-carrying capacity. 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 and intended use, but it’s not particularly powerful. The 16-inch wheels are fitted with 225/65 R16 tires, providing a good balance between comfort and durability.
Market Reception & Comparison
The Renault Master III, and specifically the 2.3 dCi 170 hp automatic variant, was generally well-received by critics and operators. It was praised for its spacious interior, robust construction, and relatively fuel-efficient engine. 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. Fuel economy figures of around 32-33 mpg (US) were considered respectable for a vehicle of this size and weight. Reliability was generally good, although some owners reported minor issues with the electronic systems.
Legacy
The Renault Master III 2.3 dCi 170 hp automatic has proven to be a reliable and durable workhorse. On the used market, these vans continue to be popular choices for businesses and tradespeople. The M9T engine, while not without its quirks, is generally considered to be a robust and long-lasting unit, provided it has been properly maintained. Regular servicing, including oil changes and filter replacements, is crucial for ensuring the longevity of this powertrain. The availability of spare parts is good, and the relatively simple mechanical design makes it relatively easy to repair. Today, these vans represent a cost-effective and practical solution for a wide range of commercial applications.
