Powertrain & Engine Architecture
The heart of the Renault Master III 2.3 Energy dCi (145 hp) is the M9T engine, a 2.3-liter inline-four cylinder diesel. This engine benefits from a twin-turbocharger setup with an intercooler, designed to deliver a balance of power and fuel efficiency. The common rail direct injection system ensures precise fuel delivery, contributing to cleaner combustion and improved performance. The 145 horsepower peak is achieved at 3500 rpm, while the substantial 360 Nm (265.52 lb-ft) of torque is available from just 1500 rpm, making it well-suited for hauling and carrying loads. The six-speed manual transmission was the standard offering for this variant, providing a good spread of gears for both urban driving and highway cruising. While an automated manual transmission (AMT) was available on some Master III models, it wasn’t commonly paired with this specific engine and trim level.
Driving Characteristics
The 145 hp 2.3 dCi engine, coupled with the six-speed manual gearbox, provides a reasonably responsive driving experience for a large van. While not designed for outright speed, the ample low-end torque makes it capable of carrying heavy loads without feeling strained. The gear ratios are well-chosen, allowing for comfortable cruising on the highway and sufficient power for overtaking maneuvers. Compared to the higher-output 170 hp version of the 2.3 dCi, this variant offers a slight trade-off in performance for improved fuel economy. The manual transmission provides drivers with greater control, especially when navigating challenging terrain or carrying a full load. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen.
Equipment & Trim Levels
The SL28 trim level represents a mid-range offering within the Master III lineup. Standard equipment typically included 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 for hard work rather than luxury. Upholstery is typically hard-wearing fabric. Optional extras available for the SL28 included features like rear parking sensors, cruise control, a more advanced audio system, and upgraded security features. The focus of this trim was on providing essential features for commercial use at a competitive price point.
Chassis & Braking
The Renault 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 a coil spring and anti-roll bar, offering a reasonable level of comfort and handling. The rear suspension utilizes a leaf spring design, prioritizing load-carrying capacity over ride comfort. 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 sporty. The 215/65 R16 tires provide a good balance of grip and durability.
Market Reception & Comparison
The Renault Master III 2.3 Energy dCi (145 hp) L1H1 SL28 was generally well-received by critics and operators alike. It was praised for its fuel efficiency, reliability, and practicality. Compared to other vans in its class, such as the Fiat Ducato and Mercedes-Benz Sprinter, the Master offered a competitive price point and a good level of standard equipment. The 145 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 170 hp variant. Fuel economy figures of 7.0-7.2 l/100 km (33.6 – 32.7 US mpg) were considered respectable for a vehicle of this size and weight.
Legacy
The Renault Master III, including the 2.3 Energy dCi (145 hp) variant, has proven to be a durable and reliable workhorse. The M9T engine, while not without its quirks, is generally considered to be a robust unit when properly maintained. On the used market, these vans continue to be popular choices for businesses and tradespeople due to their affordability and practicality. Common maintenance issues include turbocharger wear and potential problems with the diesel particulate filter (DPF), particularly on vehicles that have primarily been used for short journeys. However, with regular servicing and preventative maintenance, these vans can provide many years of reliable service.
