The Hyundai HD65, 72 and 78 models share the same design and underpinnings and were engineered as light or medium duty commercial vehicles available with various body options. Thanks to its versatility the Hyundai’s HD series can be used for a wide range of commercial applications which demand a tough and flexible vehicle able to get the job done without thinking twice.

The trucks are available with three cab configurations including the Crew, Standard and the Extended version which ads 300mm of extra carrying space being designed especially for long distance operations.

The truck also offers big load carrying abilities with deck lengths between 5.3 and 6.6 meters depending on the model. The HD series vehicle has various GVW (Gross vehicle weight) ratings including 6.5t (HD65), 7.2t (HD72) and 7.8t (HD78) models.

The Hyundai HD65, 72 and 78 models feature a cab over engine configuration with a robust design mixed with a few dynamic creases to make it stand out from the crowd.

The front fascia features a black rectangular grille and bares the company’s logo in its center. The grille is flanked by two odd light clusters which feature a sharp raked top line and are fitted with integrated turn lights.

The bumper is painted in the same color as the body and gels well with the rest of the design. It is also fitted with two round foglamps which add the finishing touch to the front fascia.

The truck has a pretty high ground clearance and for easy access there are available a pair of convenient lateral safety steps mounted under the doors. Servicing and regular checks can be made pretty easy thanks to a 50-degree tilting cab which provides quick access to the engine compartment.

The interior looks a bit more upscale than the smaller HD4. The dashboard keeps the same cheap locking wood trim, but it features a convenient wraparound design which offers easy access to the numerous controls and switches. Unsurprisingly, the materials are part of the third class and every plastic is hard as a rock. The truck also features a floor mounted gear knob which is a more difficult to use than the modern dash mounted units.

There’s nothing inherently wrong with the instrument cluster, but its dated design just looks out of place in a contemporary truck and Hyundai could do better. Same story with the two spoke steering wheel which looks borrowed from a 20 years old truck.

The driver’s seat lacks those convenient armrests found at other trucks in the business, but instead they offer adequate side bolstering and come with plenty of adjustments to permit you to find a good driving position.

Talking about driving position, the high seats offer a commanding view of the road, and while the windshield is a bit smaller than you’d expect from a vehicle of this size, the straight road visibility is not affected. We don’t have any complains about the side visibility either, as the generous door windows and the huge lateral mirrors keep you well informed at all times.

Up front, there is room for another two passengers and both of them have adequate shoulder and legroom. For an increased practicality, the middle passenger’s backrest can be folded to form a convenient console fitted with two cup holders. There are another various storage places available all-around the cabin and besides the conventional glove box and the common door pockets there are also available some handy over head consoles.

Engines and performance

The HD trucks are powered by Hyundai’s D4 diesel engine which delivers powerful performances, combined with a strong reliability. There engine comes with six different outputs available with maximum power ratings ranging from 100 hp-140 hp.

Regardless of the situation, the D4 engines can deal effortless with any demand. The engines are also surprisingly smooth, but they lack the efficiency of their rivals.

The Hyundai HD 75is mated on a five speed manual gearbox, while the other two versions are bolted to six speed manual transmissions which send power to the rear wheels. The transmissions feature triple cone synchronizers which make them smoother and precise, being able to deal with the utilitarian jobs of the vehicle with ease.

Ride and handling

All Hyundai HD models feature a floating cab suspension which uses four oil cushioned rubber mounts to soak the bumps and potholes. This suspension setup is combined with a coil suspended driver’s seats and all work fairly well in keeping the ride comfort at an adequate level.

A heat-treated, web strengthened, ultra-rigid Super Frame provides the chassis basis for a wide range of arduous applications, while an optimal suspension resilience, comes from the proven leaf springs which come with shock absorbers for increased comfort. Thanks to this configuration, the vehicle has a pretty good balance with a minimum body roll effect.

The stopping power is assured by self adjusting large brake liners combined with ABS and EBD as standard safety features. A full-size driver’s airbag is also available for enhanced safety.

There are many arguments which could convince you that the Hyundai’s HD series is good for your business. It’s cheap, smooth, reliable and versatile, which hits many of the attributes wanted in this segment. It’s true that the vehicle is a bit south of stylish, but the small trucks segment isn’t the industry’s canvas of choice to display cutting-edge design.

While we can see why the some may appreciate Hyundai HD’s attributes, there are also a lot of not-so-shiny details regarding this model. Starting with the poor build quality and the dated interior design, and finishing with the not-so-efficient diesel engines the Hyundai HD series would need some fast technological upgrades if it wants to survive with success on the highly competitive segment of light and medium duty commercial trucks.
