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 common-rail direct fuel injection system, operating at very high pressures, ensures efficient combustion 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. This low-end torque is particularly beneficial for a commercial vehicle, providing strong pulling power and minimizing the need for frequent gear changes. The engine is Euro 6 compliant, incorporating a particulate filter and Start & Stop system to meet stringent emissions regulations. The six-speed manual transmission was the standard offering for this variant, providing a balance between fuel efficiency and driver control.
Driving Characteristics
The 170 horsepower engine, coupled with the six-speed manual gearbox, provides adequate performance for most commercial applications. While not a sports van, the Master III offers sufficient power for highway cruising and carrying substantial loads. The gear ratios are well-chosen to maximize fuel efficiency and keep the engine within its optimal torque band. Compared to lower-powered versions of the Master III, this variant offers noticeably improved acceleration and hill-climbing ability. However, it doesn’t match the refinement or outright performance of some competitors with more powerful engines. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen, but it contributes to the van’s high payload capacity.
Equipment & Trim Levels
The SL33 trim level represents a mid-range offering within the Master III lineup. Standard equipment typically included air conditioning, a driver’s airbag, electric front windows, a basic audio system with USB connectivity, and a height-adjustable steering wheel. The interior is functional and durable, prioritizing practicality over luxury. Optional extras available for the SL33 included a passenger airbag, rear parking sensors, cruise control, a more advanced audio system with Bluetooth connectivity, and upgraded seating. The van’s cabin is designed with driver comfort in mind, offering a relatively ergonomic layout and ample storage compartments.
Chassis & Braking
The Master III utilizes a front-wheel-drive layout, contributing to its relatively low load floor and improved fuel efficiency. The front suspension employs an independent McPherson strut design with coil springs and an anti-roll bar, providing decent handling and ride comfort. The rear suspension features a robust leaf spring setup, optimized for carrying heavy loads. The braking system consists of ventilated discs at the front and solid discs at the rear. The van’s relatively modest weight for its class, combined with the effective braking system, provides adequate stopping power. The 16-inch steel wheels are standard, fitted with 225/65 R16 tires.
Market Reception & Comparison
The Renault Master III 2.3 Energy dCi 170 was generally well-received by critics as a practical and economical workhorse. It offered a good balance between performance, fuel efficiency, and payload capacity. Compared to the lower-powered 125 hp version, the 170 hp variant provided a significant improvement in drivability, particularly when fully loaded. However, some reviewers noted that the ride quality could be improved, especially when the van was unladen. In terms of fuel economy, the Master III 2.3 dCi 170 achieved respectable figures, averaging around 32-33 mpg in combined driving conditions. Competitors such as the Ford Transit and Mercedes-Benz Sprinter offered similar levels of performance and practicality, but the Master III often represented a more affordable option.
Legacy
The M9T engine, while generally reliable, is known to require regular maintenance, particularly regarding the turbocharger and fuel injection system. Proper servicing and the use of high-quality oil are crucial for ensuring long-term durability. Today, used examples of the Master III 2.3 Energy dCi 170 are readily available and represent a cost-effective option for businesses and tradespeople. The van’s robust construction and relatively simple mechanicals make it a relatively easy vehicle to maintain and repair. Its spacious cargo area and practical features continue to make it a popular choice in the used commercial vehicle market.
