INTRODUCTION
The Renault Master III Phase II 2.3 Energy dCi 170, in its L2H2 MM33 configuration, is a front-wheel-drive, diesel-powered panel van designed for commercial applications. Production of this specific variant ran from 2017 to 2018. It represents a mid-range offering within the Master III lineup, positioned between lower-powered, more economical versions and higher-output models geared towards heavier loads or more demanding applications. The “Energy” designation signifies Renault’s focus on improving fuel efficiency through engine technology and aerodynamic refinements. The van’s L2H2 dimensions – a medium length and medium roof height – provide a practical balance between cargo volume and maneuverability, making it suitable for a wide range of businesses.
Powertrain & Engine Architecture
At the heart of this Master variant lies the Renault M9T 2.3-liter four-cylinder diesel engine. This engine is characterized by its twin-turbocharger setup and common-rail direct fuel injection. The twin-turbo configuration, utilizing a small and a large turbocharger, aims to minimize turbo lag and provide a broader torque curve. The common-rail system, operating at very high pressures, ensures precise fuel delivery and contributes to efficient combustion. The engine produces 170 horsepower at 3500 rpm and 380 Nm (280.27 lb-ft) of torque at 1500 rpm. This specific model is paired with a six-speed manual transmission, delivering power to the front wheels. The engine incorporates a particulate filter to meet stringent Euro 6 emission standards, and a Start & Stop system further enhances fuel economy in urban driving conditions.
Driving Characteristics
The 170 horsepower and 380 Nm of torque provide adequate performance for typical commercial van duties. While not exceptionally quick, the engine delivers sufficient power for highway cruising and carrying moderate loads. The six-speed manual transmission allows for precise gear selection and helps to keep the engine within its optimal operating range. 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 outright performance of the higher-output engines available in the lineup. The front-wheel-drive configuration provides predictable handling, but traction can be limited on slippery surfaces when fully loaded. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen.
Equipment & Trim Levels
The Renault Master III Phase II 2.3 Energy dCi 170 L2H2 MM33 typically came equipped with a functional, work-oriented interior. Standard features generally included a driver’s airbag, ABS brakes, power steering, and a basic audio system. The cabin typically featured durable, easy-to-clean plastic trim and hard-wearing upholstery. The dashboard layout is straightforward and prioritizes functionality. Optional extras could include air conditioning, a passenger airbag, rear parking sensors, a navigation system, and Bluetooth connectivity. Trim levels varied depending on the market, but generally focused on adding comfort and convenience features rather than cosmetic enhancements.
Chassis & Braking
The Master III utilizes a robust ladder-frame chassis, providing a solid foundation for carrying heavy loads. The front suspension employs an independent McPherson strut setup with coil springs and an anti-roll bar, offering a reasonable level of ride comfort and handling. The rear suspension utilizes a leaf spring design, chosen for its durability and load-carrying capacity. Braking is handled by ventilated discs at the front and solid discs at the rear. The braking system is assisted by ABS (Anti-lock Braking System) to enhance stability during emergency stops. The van rides on 16-inch steel wheels, typically fitted with 225/65 R16 tires.
Market Reception & Comparison
The Renault Master III 2.3 Energy dCi 170 was generally well-received by commercial vehicle operators. Critics praised its fuel efficiency, respectable performance, and practical cargo capacity. Compared to the lower-powered 130 hp version, the 170 hp model offered a significant improvement in drivability, particularly when carrying a full load. However, some reviewers noted that the ride quality could be improved, especially when unladen. In terms of fuel economy, the 2.3 Energy dCi engine offered competitive figures compared to similar diesel engines in the segment. Reliability reports suggest that the M9T engine is generally durable, but regular maintenance is crucial to prevent issues with the turbochargers and fuel injection system.
Legacy
The Renault Master III 2.3 Energy dCi 170 remains a common sight on European roads today. The M9T engine, while not without its potential issues, has proven to be reasonably reliable when properly maintained. On the used market, these vans represent a cost-effective option for businesses requiring a versatile and capable commercial vehicle. Parts availability is generally good, and the relatively simple mechanical design makes them relatively easy to repair. However, potential buyers should be aware of the potential for turbocharger and fuel injector problems, and a thorough inspection is recommended before purchase. The Master III, and this variant in particular, solidified Renault’s position as a key player in the competitive large van segment.
