PETALING JAYA: The 1.9-litre single cab model of the Isuzu D-Max, loaded to its maximum permissible capacity of a tonne, has succeeded in yet another fuel economy challenge.

The fully-loaded pick-up truck was driven through some of the highest accessible hills along the Titiwangsa Mountain Range, and reached its destination after clocking 1,145km without needing to refuel – with two bars of fuel remaining in the tank.

Prior to starting its journey from the Isuzu-Hicom Malaysia factory in Pekan, Pahang, a thorough inspection of the test Isuzu D-Max 1.9-litre Single Cab model was conducted by Puspakom to verify its conformity as a showroom-standard unit before ensuring the weight of the load exceeded the 1,000kg target.

With its crates, bonnet and fuel tank sealed, the Isuzu D-Max headed north for its first challenge – the East-West highway linking Jeli in Kelantan and Gerik in Perak with a climb to the peak of 1,052m before heading to Ipoh for the night.

The next day, the challenge was even more daunting as the lone white Single Cab embarked on the arduous climb up 1,112m to Tanah Rata in Cameron Highlands before heading on to Fraser’s Hill (1,222m) via Raub.

From there, the journey took on an even-bigger challenge; the 1,604m-high climb up to Genting Highlands before ending the journey at the Isuzu Service Centre in Shah Alam after clocking 1,145km.

Consuming an average of just 7.2L100km (13.7kmL) based on the reading from its on-board computer, the 1.9L Single Cab arrived through the gates of the finish point with ample fuel to spare in its 76-litre tank.

“Through advanced technology, the new 1.9-litre RZ4E-TC engine is by far the most fuel efficient engine ever produced by Isuzu Motors and this was clearly demonstrated in this exercise. Perhaps some vehicles can travel long distances on a tank of fuel, some can probably manage to carry a ton of weight or climb mountains. But to achieve all three criteria with one vehicle is a true feat of a competent vehicle,” added CEO of Isuzu Malaysia Koji Nakamura.

Powered by the latest 1.9-litre Blue Power diesel engine that produces more power and torque than the 2.5-litre model it replaces, the Isuzu D-Max Single Cab model maximizes its performance through innovative technologies including a novel combustion chamber and intake manifold design, a new fuel injection system that provides more accurate fuel atomization and a newly-developed Variable Geometry (VGS) Turbocharger that delivers better engine response over a wider rev range.

Combined with low-friction parts that have been coated with Molybdenum and Graphite, the engine is able to provide enhanced reliability while reducing stress on individual components.

These combine to reduce the engine weight by 56kg making new Isuzu D-Max 1.9-litre Blue Power models one of the most dependable and affordable pick-up trucks on the market due to its lower maintenance costs and reduced road tax.

All Isuzu D-Max models including the 1.9-litre Single Cab come with a 5-year 150,000km warranty, ensuring that owners enjoy an ownership experience that enable them to enjoy the most of their dependable and efficient Isuzu pick-up trucks.
