The Isuzu NNR 45-150 is a versatile and capable light-duty truck that forms part of Isuzu’s renowned N-Series range, which has been Australia’s top-selling truck brand since 1989. Designed for a wide array of urban and suburban applications, the NNR 45-150 stands out for its car-licence-friendly Gross Vehicle Mass (GVM) of 4,500 kg, making it accessible to a broad range of drivers and businesses. This article delves into the key features and specifications of the Isuzu NNR 45-150, drawing upon the provided spec sheet and general knowledge of the vehicle.  

Powertrain and Performance

At the heart of the Isuzu NNR 45-150 lies the robust and efficient Isuzu 4JJ1-TCS engine. This is a 4-cylinder, 16-valve diesel engine with a chain-driven Double Overhead Camshaft (DOHC). Key specifications include:  

  • Displacement: 2,999 cc
  • Maximum Power (DIN-NET): 110 kW (148 HP) at 2,800 rpm  
  • Maximum Torque (DIN-NET): 375 Nm (277 lb.ft) at 1,600 – 2,800 rpm  
  • Induction System: Electronically controlled variable nozzle turbocharger with air-to-air intercooler  
  • Fuel Injection: Direct injection high-pressure common rail system  
  • Emission Control: Cooled Exhaust Gas Recirculation (EGR) with exhaust Diesel Particulate Diffuser (DPD), compliant with ADR 80/03 (Euro V) and EEV standards.  

The NNR 45-150 is available with two transmission options:

  1. Isuzu MYY-6E (Standard): A 6-speed manual transmission with synchromesh on all gears. It features a Power Take-Off (PTO) provision on the left-hand side of the transmission case, driven from the counter gear. The clutch is a single plate, auto-adjusting hydraulic control with vacuum assistance, and a 300 mm diameter.  
  2. Isuzu MYY-6S (AMT Pack Option): A 6-speed Automated Manual Transmission (AMT) offering both fully automated and clutchless manual operation modes. This also includes a PTO provision. The AMT utilizes a fully automated hydraulically controlled wet clutch and fluid coupling with lock-up, ensuring smooth launches and efficient power delivery. Reviews highlight the AMT’s slick operation, quick and smooth gear changes, and ability to select the appropriate gear for the driving conditions.  

The engine and transmission combination provides a good balance of power and fuel efficiency, making it suitable for both city and highway driving. The torque is readily available across a wide RPM range, offering good acceleration and responsiveness, even when carrying a significant load. The 100-litre frame-mounted steel fuel tank provides a substantial working range, estimated to be around 700 km in some reviews.

  • Overall Length: Around 6,495 mm
  • Overall Width: Around 2,057 mm
  • Overall Height: Around 2,240 mm
  • Wheelbase: 3,395 mm

The chassis frame is a cold-riveted ladder frame constructed from SAPH440 weldable steel, ensuring strength and durability. The rear frame width is 750 mm, providing a stable base for various body applications.

Weight Ratings:

  • GVM (Gross Vehicle Mass): 4,500 kg (car license permissible)

Cabin and Interior Features

The NNR 45-150 prioritizes functionality and durability in its cabin design. Key interior features include:

  • Seating: Options for a single cab (3 seats) or crew cab (7 seats), catering to different crew requirements.

  • TMW (Traffic Movement Warning): Alerts the driver if a stationary vehicle in front moves off and the driver doesn’t follow.
  • HSA (Hill Start Aid): (Manual Transmission models) Holds brake pressure when starting on an incline to prevent roll-back.  
  • ALS (Automatic Lighting System): Automatically turns headlights and taillights on or off based on ambient light levels.
  • Cornering Lamps: Provide additional illumination to the sides when turning, improving visibility in low-light conditions.  
  • Exhaust Brake: Assists in slowing the vehicle and reducing wear on the service brakes.  

Passive Safety Systems:

  • Driver and Front Passenger Airbags: Provide cushioning in the event of a frontal collision.  
  • Seatbelt Pre-tensioners (Driver and Front Passenger): Automatically tighten the seatbelts in a collision to restrain occupants.
