Powertrain & Engine Architecture
The heart of the Master III 2.3 dCi 170 is the M9T engine, a 2.3-liter inline four-cylinder diesel. This engine benefits from a twin-turbocharger setup and an intercooler, which significantly enhance power and torque delivery. The common rail direct injection system, operating at high pressure, ensures efficient fuel atomization and combustion. 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 effortless acceleration even when heavily loaded. The six-speed manual transmission was standard, offering a good balance between fuel economy and drivability. The engine’s design prioritizes durability and reliability, essential characteristics for a work van.
Driving Characteristics
The 2.3 dCi 170, paired with the six-speed manual transmission, delivers a competent driving experience. While not designed for outright speed, the engine provides ample power for everyday driving and hauling loads. The relatively short wheelbase of the L1H1 configuration contributes to improved maneuverability in urban environments compared to longer Master variants. The gear ratios are well-chosen, allowing for relaxed cruising on highways and sufficient grunt for navigating city streets. Compared to lower-powered Master models, the 170 hp version offers a noticeable improvement in acceleration and overall responsiveness. However, it doesn’t match the performance of some competitors with more powerful engines. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen.
Equipment & Trim Levels
The SL35 trim level, as featured in this variant, 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 practicality rather than luxury. Optional extras available for the SL35 included features like rear parking sensors, cruise control, a navigation system, and upgraded seating. The dashboard layout is straightforward and driver-focused, with easily accessible controls. The van’s interior is largely focused on providing a comfortable and efficient workspace for the driver.
Chassis & Braking
The Renault Master III utilizes a front-wheel-drive layout, contributing to a lower load floor and improved space utilization within the cargo area. The front suspension employs an independent McPherson strut design with coil springs and an anti-roll bar, providing a reasonable level of ride comfort and handling. The rear suspension utilizes a robust leaf spring setup, designed to handle heavy loads. The braking system features ventilated discs on the front wheels and solid discs on the rear, providing adequate stopping power for the vehicle’s weight. The 16-inch steel wheels are standard, fitted with 225/65 R16 tires.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 received generally positive reviews from critics, who praised its fuel efficiency, practicality, and robust construction. It was seen as a competitive offering in the large van segment, particularly appealing to businesses seeking a reliable and cost-effective work vehicle. Compared to the lower-powered 125 hp version, the 170 hp model offered a significant performance upgrade, making it more suitable for demanding applications. However, some reviewers noted that the ride quality could be improved, particularly when the van was unladen. Fuel economy figures of around 32 mpg combined were considered respectable for a vehicle of this size and weight.
Legacy
The Renault Master III, including the 2.3 dCi 170 variant, has proven to be a durable and reliable workhorse. On the used market, these vans continue to be popular choices for businesses and tradespeople. The M9T engine, while not without its potential issues (such as turbocharger wear), is generally considered to be a robust and long-lasting unit when properly maintained. Regular servicing and attention to potential oil leaks are crucial for ensuring the longevity of this powertrain. The Master III remains a common sight on European roads, testament to its enduring appeal and practicality.
