Powertrain & Engine Architecture
The heart of the Master III 2.3 Energy dCi 170 is the M9T engine, a 2.3-liter inline-four cylinder diesel. This engine utilizes a sophisticated twin-turbocharger setup with an intercooler, designed to deliver a broad torque curve and improved responsiveness. The fuel injection system is a common rail direct injection system, enabling precise fuel delivery and contributing to both performance and fuel efficiency. The engine produces 170 horsepower at 3500 rpm and a substantial 380 Nm (280 lb-ft) of torque at just 1500 rpm. This low-end torque is particularly beneficial for a commercial vehicle, providing strong pulling power and reducing the need for frequent downshifts. The engine is paired with a six-speed manual transmission, chosen for its durability and efficiency in commercial applications. While an automated manual transmission (AMT) was available on some Master variants, the six-speed manual was a common choice for this power output.
Driving Characteristics
The 170 hp 2.3 dCi engine, coupled with the six-speed manual transmission, provides a balanced driving experience for the Renault Master. While not designed for outright speed, the engine delivers ample power for highway cruising and carrying heavy loads. The gear ratios are well-chosen to maximize fuel economy and provide sufficient torque in each gear. Compared to lower-powered versions of the Master, this variant offers noticeably improved acceleration and hill-climbing ability. However, it doesn’t possess the refinement or responsiveness of some of its competitors with more advanced engine technologies. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen. The manual transmission requires a deliberate shift action, typical of commercial vehicles, prioritizing durability over sporty feel.
Equipment & Trim Levels
The Master III Phase II 2.3 dCi 170 L3H3 LH35 typically came with a functional, rather than luxurious, equipment list. Standard features included a driver’s airbag, ABS brakes, power steering, and a basic audio system. The cabin focused on practicality, with durable plastic trim and easy-to-clean surfaces. Trim levels varied by market, but generally offered options such as air conditioning, electric windows, a passenger airbag, and a more advanced audio system with Bluetooth connectivity. Often, businesses would specify additional features like rear parking sensors, cruise control, and navigation systems as optional extras. The interior upholstery was typically hard-wearing fabric, designed to withstand the rigors of commercial use.
Chassis & Braking
The Master III utilizes a robust chassis designed to handle substantial payloads. The front suspension employs an independent McPherson strut setup with a coil spring and anti-roll bar, providing reasonable handling and ride comfort. The rear suspension utilizes a traditional leaf spring arrangement, chosen for its load-carrying capacity and durability. Braking duties are handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard, enhancing safety during emergency braking. The steering is hydraulic power-assisted, providing a reasonable level of assistance without feeling overly light or disconnected.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 was generally well-received in the European commercial vehicle market. Critics praised its spacious interior, strong engine, and competitive fuel economy. Compared to rivals like the Fiat Ducato, Mercedes-Benz Sprinter, and Volkswagen Crafter, the Master offered a good balance of price, performance, and practicality. The 170 hp engine provided a noticeable step up in performance compared to the lower-powered variants, making it a popular choice for businesses requiring a versatile and capable van. However, some reviewers noted that the interior lacked the refinement and modern features found in some of its competitors.
Legacy
The Renault Master III 2.3 Energy dCi 170 has proven to be a relatively reliable powertrain in the used vehicle market. The M9T engine, while complex with its twin-turbo setup, is generally durable when properly maintained. Common issues include turbocharger wear and potential problems with the diesel particulate filter (DPF), particularly on vehicles that have primarily been used for short journeys. The six-speed manual transmission is known for its robustness. Today, these vans represent a cost-effective option for businesses seeking a large-capacity van with a proven track record. Their availability and relatively affordable maintenance costs continue to make them a popular choice in the used commercial vehicle market.
