With the latest update, the 1.9-liter turbodiesel engine previously used in the Isuzu D-Max for the Malaysian market has been replaced by a new 2.2-liter turbodiesel, while the 3.0-liter unit remains available.

The new RZ4F-TC 2.2L diesel engine was developed from scratch rather than being an upgrade of the old 1.9-liter. Compared to its predecessor, the 2.2-liter engine is 8.7% more powerful, delivering 163 horsepower at 3,600 rpm, with torque up 14.3% to 400 Nm between 1,600 and 2,400 rpm.

Thanks to an exhaust gas treatment system that includes a diesel oxidation catalyst, a diesel particulate filter, and an intelligent exhaust gas recirculation system, the new engine cuts harmful emissions by 21% and reduces particulate matter by 99%.

This engine also meets Euro 5 emissions standards and can run on B20 biodiesel. According to real-world testing by Isuzu in Malaysia, fuel consumption is 15.78 km per liter for the new engine, versus 14.99 km per liter for the 1.9-liter version. On a full tank, the range is about 1,352 km.

In addition to the all-wheel-drive system, the Isuzu D-Max now features a new eight-speed automatic transmission that will be fitted to the 2026 model. By comparison, the previous 1.9-liter model came with a six-speed manual gearbox. Along with a higher gear ratio, this transmission has a new shift system that speeds up gear changes and reduces power loss during shifts.

As a new offering for the D-Max, a Single Cab Automatic version has been introduced for the first time in Malaysia. This variant also boasts a larger cargo area, measuring 2,345 mm by 1,590 mm by 465 mm. It adds a new body color (silver), a new center console, and a silver front bumper.

On the styling front, the 2026 Isuzu D-Max 2.2L gets a refreshed design. The front end now features a new grille across all trims, new-color LED headlights for the Double Cab Automatic, and updated taillights.

For the rear, a new LED taillight cluster is offered on the Premium and X-Terrain versions. A tailgate assist system is now standard on all Double Cab trims (optional on Standard AT/MT). Two new body colors are also available: Inishmore Green Metallic for Premium and X-Terrain, and Obsidian Grey Mica for Premium and Auto Plus.

According to Isuzu, the new pickup has undergone durability testing, covering 2.2 million kilometers—55 times the length of the equator. The Isuzu D-Max 2.2L 2026 comes with a new service package that allows owners to have their vehicle inspected at an Isuzu service center within two years or after 20,000 km.
