Hyundai HD 78: technical specifications

One of the largest Korean companies began its promotion to the international market with close cooperation with the Mitsubishi brand. The debut models of Hyundai trucks clearly showed features and technologies inherent in Japanese cars. However, in 1998, the Koreans presented their own development - the Hyundai HD truck. The model was firmly entrenched in the market, but the company did not intend to stop there. As a result, in 2009, a series of Hyundai HD-78 commercial vehicles appeared. The model has not lost the main advantages characteristic of the products of the Korean brand (cost-effectiveness and simplicity), but has added in the quality of elements and operating comfort.

Hyundai HD-78 is a compact truck with a gross vehicle weight of 7200 kg. It is ideal for distribution work and offers outstanding maneuverability. The car is ready for daily city trips. The model is perfectly adapted to Russian realities, so it can generate profit all year round. The car is not afraid of domestic roads and fuel. A variety of types of configurations and cabins, increased load capacity, Korean assembly and a reliable power plant determine the high demand for the car.

The main purpose of the Hyundai HD-78 is transportation over short distances in the suburbs and the city. A huge number of add-ons can be installed on the model’s platform: an onboard cabin, a van, a tow truck and a manipulator. Hyundai HD-78 is currently considered the leader of the Korean brand's lineup. On the Russian market, the model took a place between expensive foreign brands (Scania and Mercedes) and domestic products (ZIL and GAZ).

Among the key advantages of the model, we should highlight the highest performance and quick payback. At the same time, the cost of the car is 10-20% less than that of “classmates”.

It is also worth mentioning the excellent maneuverability of the truck. A small turning angle allows the Hyundai HD-78 to feel confident on narrow streets, among heavy traffic and in the city. Conveniently positioned mirrors and a large windshield help the driver reverse and turn.

Already in the minimum configuration, the Hyundai HD-78 is equipped with an air conditioning system, ABS and auxiliary hydraulic devices, which increases the safety and comfort of vehicle operation.

A little about the history of the model

The HD series of small commercial trucks is derived from similar class vehicles from Mitsubishi. It was cooperation with the Japanese that became the beginning of this line of Hyundai products. The HD78 model itself has been produced since 2008. Its immediate predecessor was the Hyundai HD72.

The index means the total weight of the truck: for the predecessor it was 7.2 tons, and for the Hyundai HD78 it was 7.8 tons. However, for Russian conditions, the total weight is limited by the manufacturer to 7.5 tons.

Externally, the truck changed little - both during the transition in 2008 from the HD72 to HD78 model, and during the 2013 restyling. It is distinguished by the same “Asian” cabin, made in the original Japanese spirit, with a large, somewhat inclined windshield.

External changes have occurred in lighting technology: the headlights have become larger, and the turn signals have increased in size. Turn signals appeared as standard and on the side doors too. The basic equipment also began to have fog lights located in the bumper niches. Another external change is that after restyling, the rear-view mirrors began to be mounted in a European style, rather than in an Asian style, and it became more convenient to look through them.

The design of the cabin suspension also evolved, which began to be installed on rubber shock absorbers recessed in an oil bath. Such shock absorbers are better adapted to frost, and they more effectively soften shocks and shaking when driving on uneven roads.

And finally, one more small change, which, however, was appreciated by consumers. The manufacturer has finally abandoned such a common “Asian” thing as finishing the dashboard “like precious wood”, made of cheap plastic. It was replaced with higher quality and softer plastic.

Design and application features of the Hyundai HD78

The chassis of Hyundai trucks, which are made for Russia, is positioned by the manufacturer as reinforced and adapted to difficult road conditions. And this model is assembled for sale in Russia and the CIS, not only in Korea, but also in China, and here in Kaliningrad.

The car's suspension is leaf spring, with small leaf springs. At the rear there are semi-elliptic, laminated springs with a shock absorber. The front suspension is equipped with a stabilizer bar and shock absorbers. Shock absorbers are hydraulic double-acting, telescopic type on the front and rear axles. The brake system is equipped with improved discs with increased area. The front wheels are single, and the rear axle is paired.

The main purpose of the Hyundai HD78 is transportation over short distances around the city and on suburban routes, within the region. The chassis has a high degree of versatility: a large number of special add-ons can be installed on its platform. The most popular and widespread of which are:

The vans are isothermal, treated with polymer or coated with auto enamel. They consist of laminated plywood and clad metal.
Refrigerated vans that can maintain the required temperature for a long time. With cooling compressor. The insulation is made using polystyrene foam or polyurethane foam, with a thermal conductivity coefficient of 0.035 W/sq.m;
Manufactured goods vans made of clad metal, plastic and laminated plywood. They are coated with auto enamel and galvanized.
Bread vans, with different numbers of trays. They also have isothermal properties.
Vans with a tail lift – loading from a mechanized tailgate platform.
Crane-manipulator installations.
Car tow trucks.

The truck is very compact and maneuverable, ideally suited for working in the cramped conditions of a modern city. A carrying capacity of 5 tons and a body volume of 20 to 35 cubic meters allow the owner to profitably handle large quantities of goods for delivery to customers and (or) distribution to stores.

Adaptation to Russian conditions is not empty words. In addition to a reinforced frame and suspension, this also includes additional fuel filtration, increased ground clearance, and a reliable heating unit before starting the engine in subzero temperatures.

The cabin is quite spacious for such a compact truck, fully three-seat, heated, ventilated and air-conditioned, with ergonomic controls. Rear view mirrors are large in size and heated. There is a hydraulic power steering system, ABS, air conditioning.

The service network is well developed, and spare parts are not a problem to find. Most often, they are already available in any city (more than two hundred service centers operate across Russia); those purchased “to order” rarely have to wait. Consumables, lubricants, replaceable components and parts are not only not in short supply, but also relatively inexpensive. On the freely accessible Russian-language Internet you can find manuals and instructions for the operation and repair of Hyundai trucks, and if you wish, maintain the good technical condition of the vehicle yourself.

Modifications of the Hyundai HD 78 truck

The Hyundai HD-78 truck has a wide range of applications due to its versatility.

Several modifications of vans have been created based on Hyundai equipment:

isothermal, with a sealed body made of clad metal and laminated plywood;
manufactured goods, galvanized, coated with auto enamel;
refrigerators with freezers for long-distance transportation. Insulating properties and the ability to maintain a given temperature are provided by polystyrene foam and polyurethane foam;
sandwich panels treated with polymer;
auto shops with racks and counters;
bread , with built-in trays and side doors.

In addition, the manufacturer offers other types of Hyundai cars:

onboard platform for cargo transportation;
residential module;
a tow truck equipped with an inclined platform and a crane;
Eurokung with rear doors;
crane-manipulator with a retractable element;
mobile medical laboratory;
emergency service;
special equipment of the Ministry of Internal Affairs and the Ministry of Emergency Situations.

Equipment options

The truck can be purchased in a standard (STD) or luxury (DLX) modification. Initially, each of them includes: power steering; tow hook; heated rear view mirrors; tachometer; spare wheel; brake force regulator; mountain brake; interior heater; special floor covering; passenger sun visor; ABS system with electric brake force distributor; bumper painted in the color of the cabin; electric windows; central locking; front fog lights.

In the DLX configuration, an audio recorder with a radio receiver, speakers and an antenna is added to the above (in the STD - only audio preparation), a tint strip on the top of the windshield, and a digital clock.

Air conditioning, power take-off, a more comfortable driver's seat on a spring suspension with lumbar support, a double brake booster - these are all additional options for an additional fee for both the first and second configuration options.

In addition, Hyundai HD78 trucks are supplied with an extended (Long) base, as well as with a one-and-a-half cab, in which a compact berth is equipped by adding a width of 30 cm.

Hyundai HD78 truck engine

The HD78 is equipped with a high-torque 4-cylinder diesel engine produced by Hyundai, model D4DB. The engine is equipped with a turbocharger and an intermediate equipment system. The power of this power unit is 140 horsepower (in the updated version - 150 hp) and a working volume of 3,907 liters. Unlike most similar motors in this class, D4DB has a very wide operating range. It not only pulls well at the bottom, but also revs dynamically up to 3 thousand rpm. Another advantage of this diesel engine is that it is not stuffed with complex electronic systems, and this makes routine repairs much easier and faster. In general, access to the engine is very well thought out, in particular to its most frequently serviced components.

The power unit on cars of earlier years of production complied with Euro-3 environmental standards. Now this is Euro-4, the Common Rail electronic injection control system. Both the previous and updated versions of the engine are capable of accelerating the truck to 120 km/h. Diesel fuel consumption in the urban cycle is at the level of 15-18 liters per 100 kilometers. The fuel tank capacity is 100 liters. The maximum engine torque is 372 N*m (at 1400 rpm)

Transmission. Steering and brakes

The clutch is dry, single-disc, hydraulically driven. The gearbox is mechanical, with a power take-off shaft, 5 forward gears and 1 reverse gear. A power take-off unit with a mechanical or pneumatic drive is mounted with the gearbox. The cardan shaft is tubular, on an intermediate support with a universal joint, needle bearings, and a sliding fork. The rear axle is driven, with a single-stage transmission. The gearbox gear is hypoid, the differential gear has rectangular teeth.

The truck's gearbox (its model: M035S5 (OverDrive)) sometimes causes fair criticism. It has an outdated design with a cable-driven lever, which is quite susceptible to failures and unclear shifts when operating in lower gears. That is, the modified Hyundai HD78 inherited a five-speed gearbox from the previous model of the Korean HD72 truck.

The steering mechanism is equipped with an effective hydraulic booster, which allows the driver to change the direction of movement of the car without any load or stress. The brake system is hydraulically driven. The front wheels have a disc mechanism, the rear wheels have a drum mechanism with pads. The parking brake system is a drum with shoes on the secondary shaft of the gearbox, the drive is cable.

Modifications

You can buy a model only with a cab, that is, a chassis. Next, we offer an onboard truck for transporting bulk cargo. On request, the manufacturer installs a tow truck with a crane or a sliding platform, or a manipulator crane on the chassis.

Mostly people buy a van, but it is also available in several variants. More often they buy a simple or elongated van, they also offer an isometric van, a grain van, a van-shop, a mini-camper of 12 square meters, a cargo-passenger van, a medical van, a version for 30 people for the Ministry of Emergency Situations.

A refrigerator is also produced, but it is difficult to find. The essence of the model is the presence of several freezing generators for transporting frozen food. They don’t buy it often, because it’s easier to buy an isothermal van and modify it to meet the required purposes.

Design Hyundai HD78

Appearance is the last thing buyers are interested in, but on the other hand, initially you look at the appearance, only then decide whether it is worth considering the model in detail. The car does not stand out in the crowd; there are differences from its competitors, but they are small.

The muzzle received a rounded radiator grille. Large halogen headlights provide excellent illumination of the road, accompanied by rectangular turn signals. The optics are emphasized by an aggressive stamping line running to the end of the door. A simple unpainted bumper in the base is equipped with round fog lights.

On the side, the Hyundai HD78 door has a wave-like shape due to the same stamping. An additional turn signal has been installed in the door. Another additional turn signal is installed on the roof of the cab. A large metal step is installed to enter the cabin.

Most people buy a van that has two massive doors at the back that open 180 degrees.

There is a standard and an extended version, here are their sizes:

length – 5275 or 6715 mm;
width – 2010 mm;
height – 2285 mm;
wheelbase – 2780 or 3735 mm;
ground clearance – 200-235 mm;
maximum lifting angle is 35 degrees.

Cabin Hyundai HD78

The truck's cabin is three-seater, short (but modifications with an extended cabin and a compact berth 300 mm wide are also available).

The wide door opening and grooved step provide easy and safe access to the cab. To open access to the engine, the cabin can be freely tilted forward 55 degrees manually by one person.

The salon is quite spacious. The range of adjustments in the driver's seat is very limited, but it is quite enough to comfortably accommodate both short and tall drivers. Moreover, the steering wheel is also adjustable for reach and tilt. The driver's seat is quite hard, but overall comfortable, with lateral support. But it’s better not to be greedy when buying and buy a car with a more comfortable seat (additional option).

Inside the cabin there are many different shelves, pockets and niches. All levers, switches, keys and indicators are located ergonomically and conveniently. There is no “overkill” with all sorts of additional devices that distract the driver’s attention, but everything necessary is at hand, including an indication of open doors, an internal lighting system for the superstructure. The back of the central seat can easily be turned into a table during parking, and there is a gear shift lever the ability to turn it on its side so that it does not interfere with movement around the cabin.

Advantages of this model

Korean designers have done a good job organizing the space in the cabin. The driver's seat is quite comfortable. It has a high lift and a large number of settings. The quality of finishing materials is noteworthy. The steering wheel is adjustable for tilt and height.

This truck can be driven by a driver of any height and build. The gearshift lever folds, allowing for free movement around the cabin. An aluminum footrest provides a comfortable seating position. You should pay attention to the large rear-view mirrors, fog and main double headlights - all this provides good visibility even in poor visibility conditions.

One of the most significant advantages of this model is the high level of maintenance. There are a large number of Hyundai branded showrooms in Russia, where specialists can quickly fix all problems. Both cars and showroom services are provided with a long-term warranty. All repair work is carried out using modern equipment and original parts.

As a rule, branded centers offer corporate clients very favorable terms of cooperation. Discounts on services and individual consultations are provided. For this purpose, hotlines or forms are created on the website, with the help of which you can quickly obtain information on all issues related to vehicle maintenance.

The main advantages of this model are as follows:

efficiency (fuel consumption of a diesel engine is 15–17 liters per 100 kilometers);
maneuverability (turning radius is 7.3 meters, which ensures comfortable movement along city streets);
power (even when fully loaded the car can maintain a good speed);
capacity (all sides recline, loading height - 105 cm, useful body volume - 21 cubic meters);
reliability (the frame is made of hard, hardened steel, bolted and reinforced with traverses);
versatility (a large number of different add-ons can be placed on the chassis).

One of the most significant advantages of this model is the high level of maintenance.

Reviews from owners and drivers

According to the vast majority of people who know the Hyundai HD78 first-hand, this truck is one of the best in its category in terms of price/quality ratio. A successful engine - reliable, not capricious and high-torque (and when necessary, very revvy). True, fuel consumption in urban conditions is slightly higher than the indicators indicated by the manufacturer. But this surprises few people these days. Very easy to control and maneuverable, like a car.

Good load capacity and capacity – 5 tons, 10 pallets. A good margin of safety for all components and parts of the structure. Chassis, suspension, engine, comfort, handling - everything in the Hyundai HD78 is “tailored” for daily intensive work. The car is good for short and medium distances. This is a truck for daily work. For everyday work. It quickly pays for itself and begins to make a profit. There is nothing superfluous, but everything necessary for daily work is present.

The downside is that the seat in its basic version is not very comfortable (“like a stool”); poor cabin sound insulation; its susceptibility to corrosion; problems with springs if you regularly practice fully loading or overloading the machine. Springs and cushions can be reinforced with GAZel sheets.

Interesting reviews from owners who themselves work behind the wheel of purchased new Hyundai HD78:

“Now the mileage is more than 300,000 kilometers. I changed the steering cross, the suspension bearing, the steering ends and the outer bearing of the front hub.”

“Over the entire run, I changed the kingpins, suspension bearing and crosspiece at the bridge at 200 thousand km, replaced the steering tips at 150 thousand km, the heater radiator leaked - replaced it with a VAZ copper-brass one from the eight; the hose on the power steering burst (cracked), the outer bearing of the front hub recently became damaged - nothing else has been repaired yet.”

“I bought a new HD-78, it has already covered almost 170 thousand km, I only changed consumables, i.e. oils, filters, brake fluid, antifreeze and once alternator belts at 150 thousand, although dealers change it after 40 thousand if you put it under warranty . I didn’t put a warranty on it and don’t see the point, the car is quite reliable. So my friend put the 78th under warranty and, as they say, threw away a little over a hundred thousand rubles for this guarantee.”

Flaws

The main problem of the car is the body; it is too susceptible to corrosion, so it’s not worth buying old used versions. They criticize the driver's seat, it is very uncomfortable. If you constantly overload the Hyundai HD78, the springs begin to deteriorate, but you can strengthen them with springs from the Gazelle.

The truck travels 100-150 thousand kilometers without any problems, little things are changed under warranty. Then some minor problems begin:

replacement of outboard bearings;
replacement of steering tips;
heater radiator leak;
Power steering hoses become unusable;
replacement of outer wheel bearings, etc.

It’s difficult to call it unreliable; parts cannot live forever; this applies to absolutely all cars.
