Features of the Isuzu NQR71 medium-duty truck
While our manufacturers of light commercial vehicles are struggling in their death throes, kept afloat by government orders, large-scale assembly of trucks of foreign origin is in full swing in Russia. Among them is the medium-duty Isuzu NQR71.
Analogy with China
Over the course of a year, exactly one thousand Isuzu NQR71 trucks were assembled at the production facilities of the Ulyanovsk Automobile Plant using a screwdriver method. Let's face it, it's not very good. Some analysts even began to talk about the commercial failure of the project to assemble Japanese trucks in Russia. The main argument of skeptics is the inflated price of the Isuzu NQR71 in comparison with the cost of similar cars from China. Well, there is some truth in these arguments. True, only a fraction. Chinese cars really please the stingy souls of our “commercials” with almost dumping prices and attractive appearance. However, trucks from the Middle Kingdom, which are direct competitors of the Isuzu NQR71, are inferior to the latter both in build quality and in the materials used in the interior trim. And in terms of driving performance, the Isuzu NQR71 is a step above its younger “Chinese” brothers. How the Chinese manage to assemble mega-cheap cars using Japanese licenses is an interesting topic, we will definitely return to it. Today we’ll try to find out whether the “Russian screwdriver” spoils the legendary Japanese quality.Interior features
As usual, let's start with the interior. Getting inside the cabin is easy. The wide lattice step and several handles on the interior door panel make it easy to straddle the high chair. The rubberized upholstery of the chairs immediately reminded me of oilcloth - unpleasant, but functional: these chairs are not afraid of dirt, dust, or oil stains. Yes, and wiped bald spots will not appear on them any time soon. Unlike many Chinese cars, the Isuzu NQR71 does not have the back of the driver's seat resting on the rear of the body. There is more than enough free space behind the seat. The ability to independently choose the angle and height of the steering column helps the driver to sit comfortably behind the steering wheel. The amplitude of the tilt is about 10 cm, and the height is within 5-7 cm (for cars from the Middle Kingdom, the adjustable play of the steering column in tilt is 4-6 cm, if not less, and in most cases there are no height adjustments at all). The plastic used in the interior decoration of the Isuzu NQR71 cannot be called expensive. However, the interior of the “Japanese” does not look like a cheap enamel pan painted with glossy wood-like paint. Budget-friendly, modest, well-made - that's what I want to say about the interior of Isuzu. But why are there two ashtrays in the interior of the truck? Clan of millionaires
The car is equipped with a 4-cylinder diesel engine 4HG1-1, belonging to the clan of the so-called millionaires. In other words, with appropriate maintenance, the power plant will only reach a major overhaul after covering a million kilometers. In terms of “exhaust”, the engine complies with the rather outdated Euro-2 standard. As a result, the 4.6-liter engine honestly produces a “herd” of rather frisky “horses” numbering 121 heads. The high-spirited nature of the car is also due to the very well-chosen gear ratios in the gearbox. The key is to start - the Isuzu starts briskly from second gear. A quick and clear transition to the third stage, then we “stick” the fourth. On the speedometer - 80-90 km/h. However, as the speed increases, the positive mood deteriorates in direct proportion to the increasing noise from the running engine, which easily penetrates the cabin. We slow down the speed to a more or less comfortable 100 km/h and give an unkind word to the car developers who saved on noise insulation. Or maybe they just forgot to screw it on? We brake, tilt the cab to the side, and in one motion “break the neck” of the Isuzu. No, everything is okay. Shiny layers of noise-canceling material are screwed where they should be. This means that the audio equipment in the truck needs to be installed more powerfully and turned up louder... Basic equipment
The basic equipment of the truck includes an ABS system, a mountain brake and power steering. Passenger vehicle owners have long been accustomed to such a simple set of options. For the majority of drivers of domestic commercial "medium-duty vehicles", these basic "devices" are still a novelty. The total weight of NQR71 is 8 tons. In its “naked” form, the chassis weighs 2.5 tons. Accordingly, the payload reserve is over five tons. With such potential, anything from a boring van to the beams of a 2-tier tow truck can be mounted on the steel spine of the frame. All components and assemblies from which the NQR71 is assembled in Russia are supplied by Isuzu. The issue of localization of production is under consideration. The plant plans to increase production to 10,000 cars per year. The ambitions inspire respect, but so far, in our opinion, they are groundless. Severstal-Auto, of course, has the technical and financial capabilities to increase circulation. But our consumers are not yet ready to buy packs of commercial trucks in the $30,000 price segment. Firstly, there is trivially no money. Secondly, it takes time for Russian business to eventually understand that the stingy really pays twice.

One of the activities of the Japanese corporation Isuzu Motors Limited is the development and production of trucks and power units.
The corporation's cars appeared on the Russian market in the late 80s of the last century - they were supplied through barter schemes in exchange for Siberian coal.
Currently, the company successfully cooperates with Sollers OJSC (a structure of the Severstal group). With him in 2010, SOLLERS-ISUZU CJSC was formed.
The purpose of cooperation is the production of commercial vehicles and its sale through a network of dealership centers.
According to the manufacturer's classification, the light small-tonnage truck is classified as the N series. These are universal vehicles for urban and suburban transportation of goods up to 5 tons.
The chassis provides for the installation of vans for various purposes, a loading platform, a crane, and equipment for towing vehicles.
Purpose and features
In recent years, the use of light-duty vehicles has been increasing.
Such machines are compact and convenient. NQR75 has found a scope of application in small enterprises that need to deliver equipment or goods to sites, in small transport companies that make money by transporting not very large consignments.
The car is easy to drive, it is quite maneuverable, economical, and also not very difficult to repair.
All this makes it possible to profitably use it on intra-city routes, for the needs of private land ownership, and when running a farm.
The main features of the car are the simplicity of the design and the following factors:
