In the upcoming year of 2025, Isuzu is expected to unveil a fully electric version of the D-Max. However, before this mid-size truck hits the market, a new power option has already arrived in Thailand.
The D-Max and its closely related counterpart, the MU-X, are now equipped with a new mild hybrid diesel engine that promises enhanced performance and fuel economy. This 2.2-liter turbocharged hybrid diesel engine, codenamed RZ4F, produces a robust 161 horsepower and a torque of 400 Nm.
Isuzu claims that this engine operates more quietly, boasts improved combustion efficiency, and features a unique turbocharger. However, details about the electric motor and the 48-volt battery have yet to be disclosed. The new 2.2-liter engine comes paired with an 8-speed automatic transmission, contributing to improved performance and efficiency.
According to official information, this mild hybrid system provides 56% more torque at startup and offers a 10% better fuel economy compared to the conventional non-hybrid diesel engine. Additionally, the base engine for both the D-Max and MU-X is a 1.9-liter unit that delivers 148 horsepower, while the top-tier 3.0-liter engine can generate 187 horsepower, available with either a 6-speed manual or a 6-speed automatic transmission. The hybrid versions are set to go on sale on November 28, with prices for the D-Max ranging from $17,200 to $27,000, and the MU-X starting at $34,435.
