INTRODUCTION
The Renault Master III Phase III 2.3 Energy dCi 150 hp Automatic is a large panel van designed for commercial use. Introduced in 2019 as part of the Phase III refresh of the third-generation Master, this variant offers a balance of power, efficiency, and practicality. The L3H3 configuration signifies a long wheelbase and high roof, providing a substantial cargo volume of 14.8 cubic meters (522.66 cu. ft.). This model is built on Renault’s robust ladder-frame chassis and is targeted towards businesses needing a reliable and spacious van for deliveries, tradespeople, and conversions. The automatic transmission option, paired with the 2.3-liter diesel engine, aims to improve driver comfort and ease of use, particularly in urban environments.
Powertrain & Engine Architecture
At the heart of this Master variant lies the Renault M9T 2.3-liter four-cylinder diesel engine. This engine utilizes a twin-turbocharger setup with an intercooler, boosting power output to 150 horsepower at 3500 rpm and 385 Nm (283.96 lb-ft) of torque at 1500 rpm. The engine employs a diesel commonrail direct injection system, ensuring precise fuel delivery and optimized combustion. The M9T engine is known for its relatively robust construction and ability to handle high mileage. The automatic transmission is a six-speed unit, designed to provide smooth gear changes and efficient power delivery. While not a dual-clutch transmission, it’s geared towards durability and ease of maintenance. The inclusion of a Start & Stop system and a particulate filter contributes to reduced emissions, helping the van meet Euro 6d-Temp standards.
Driving Characteristics
The 150 hp automatic configuration of the Master L3H3 delivers adequate performance for most commercial applications. Acceleration is not its strong suit, with a 0-60 mph time of around 11.5 seconds, but the readily available torque from the twin-turbo diesel engine makes it capable of handling fully loaded cargo. The automatic transmission provides smooth shifts, particularly beneficial in stop-and-go traffic. Compared to the manual transmission versions, the automatic offers increased driver comfort, but may result in a slight reduction in fuel economy. Higher-output versions of the Master, such as those with the 170 hp engine, offer noticeably quicker acceleration and improved performance when carrying heavy loads. The gear ratios are tuned for maximizing fuel efficiency and providing sufficient pulling power, rather than outright speed.
Equipment & Trim Levels
The Renault Master III Phase III 2.3 Energy dCi 150 hp Automatic typically comes with a functional, work-oriented interior. Standard equipment generally includes air conditioning, a basic audio system with USB connectivity, electric windows, and central locking. Safety features include ABS, ESP (Electronic Stability Program), and driver and passenger airbags. The cabin is designed for durability and ease of cleaning. Optional extras often include a touchscreen infotainment system with navigation, rear parking sensors, cruise control, and upgraded seating. Interior trim is typically utilitarian, with hard-wearing plastics and vinyl upholstery. The focus is on practicality and longevity rather than luxury.
Chassis & Braking
The Master’s chassis is a traditional ladder-frame construction, providing a robust and durable platform for heavy loads. The front suspension utilizes an independent McPherson strut setup with a coil spring and anti-roll bar, offering a reasonable level of ride comfort. The rear suspension employs a leaf spring design, chosen for its load-carrying capacity and simplicity. Braking is handled by ventilated discs at the front and solid discs at the rear. The braking system is adequate for the van’s weight and intended use, but it’s not particularly sporty. The van’s relatively high center of gravity and substantial weight necessitate careful driving, especially when cornering.
Market Reception & Comparison
The Renault Master III Phase III 2.3 Energy dCi 150 hp Automatic was generally well-received by commercial vehicle operators. Critics praised its spacious interior, robust construction, and relatively fuel-efficient engine. However, some noted that the automatic transmission could feel slightly sluggish when fully loaded. Compared to other vans in its class, the Master offered a competitive combination of price, payload capacity, and running costs. The 150 hp engine provided a good balance between performance and economy, making it a popular choice for businesses that didn’t require the extra power of the higher-output versions. Fuel economy figures of around 9.9 l/100 km (23.8 US mpg) were considered reasonable for a van of this size and weight.
Legacy
The Renault Master III Phase III 2.3 Energy dCi 150 hp Automatic has proven to be a reliable and durable workhorse for many businesses. The M9T engine, while not without its quirks, is generally considered to be a robust unit capable of high mileage with proper maintenance. The automatic transmission, while not the most sophisticated, has also proven to be relatively reliable. On the used market, these vans represent good value for money, offering a lot of space and practicality for a reasonable price. However, potential buyers should be aware of the importance of regular maintenance, particularly regarding the diesel particulate filter and turbocharger. The Master continues to be a popular choice in the large van segment, and the Phase III models represent a refined and capable iteration of this versatile vehicle.
