Isuzu Philippines Corporation (IPC) finally completes its Blue Power offering with the launch of the 2018 mu-X and D-Max powered by the all-new 1.9-liter RZ4E Blue Power engine. Six months after showing off its 3.0-liter Euro 4 compliant engine, IPC now welcomes this downsized engine to the market for those wanting a mix of power and efficiency.
“The global trend of producing smaller capacity engine that has an output of larger engines has come to Isuzu,” said IPC President Hajime Koso. “The new RZ4E Blue Power engine, carries with it our years of experience as a diesel engine manufacturer. Carefully developed to provide optimized power and torque; this engine performs efficiently, with much care for the environment, running with less noise & vibrations, and is very easy to maintain,” he added.
With four years of testing and development, the Isuzu RZ4E engine features a displacement of just 1,898-cc or 1.9-liters. And yet, this Euro 4 compliant engine produces a maximum output of 150 horsepower at 3,600 rpm and 350 Nm of torque at 1,800-2,600 rpm, easily matching Isuzu’s own 2.5-liter 4JK1-TC engine.
This new engine has several technological features that promote better fuel efficiency and better emissions including: an optimized combustion chamber with diamond-like coated piston pins and fuel injector needles, and fractured split-design connecting rods. The RZ4E also features a water-cooled variable-geometry turbocharger with a turbine made from high-temperature resistant material.
For easier and lower cost of maintenance, the RZ4E engine has Hydraulic Valve Lash Adjusters (HVLA) which keeps the correct valve lash clearance, a single engine accessory drive belt, a cartridge-type oil filter, and a steel timing chain with automatic chain adjuster.
Given its new design, the RZ4E engine easily outpaces the previous 2.5-liter variants. During IPC tests, the Isuzu mu-X RZ4E LS-A MT records 37.27 km/L which is a 14.32 percent improvement from before, while the mu-X AT logs 35.80 km/L or a whopping 48.36 percent better than before.
The test was conducted under the supervision and verification of the Automobile Association Philippine (AAP) following the Department of Energy (DOE) testing parameters and standards.
Set to replace Isuzu’s existing 2.5-liter variants, this engine will be made available in both the Isuzu mu-X and D-Max models.
As an entry-level model (and potentially a replacement to its Crosswind AUV), the Isuzu mu-X RZ4E LS 4x2 MT offers comfort and convenience without breaking the bank. Moving up, the new Isuzu mu-X RZ4E 4x2 LS-A MT and AT variants are packed with top-of-the-line SUV features perfect for those who need something smart and functional but still easy on the pocket.
Similar to the mu-X, the Isuzu D-Max will have its own smart and functional variants: the Isuzu D-MAX RZ4E 4x2 LS MT and AT. Ideal for urban drivers, these two new variants offer a comfortable driving experience while maintaining its cargo truck capabilities.
The new Isuzu mu-X RZ4E variants are available in five color options: Havana Brown, Cosmic Black, Obsidian Gray, Titanium Silver, and Silky Pearl White. Prices are as follows:
- Isuzu mu-X RZ4E 4x2 LS MT - P 1,395,000
- Isuzu mu-X RZ4E 4x2 LS-A MT - P 1,570,000
- Isuzu mu-X RZ4E 4x2 LS-A AT - P 1,595,000
As a reference, the mu-X 3.0-liter Blue Power still sits atop the range with two variants:
- Isuzu mu-X 4JJ1-TCX 4x2 LS-A AT - P 1,845,000
- Isuzu mu-X 4JJ1-TCX 4x4 LS-A AT - P 2,145,000
For the Silky White Pearl premium color, an additional P 10,000 will be added to the vehicle price. This color is only available on the LS-A.
Deliveries of the 2018 mu-X 1.9 Blue Power starts in April. For the D-Max 1.9 Blue Power, pricing and final specifications will be announced closer to its launch date in June.
IPC will be displaying the mu-X 1.9 Blue Power at the Manila International Auto Show (MIAS) this April 5-8, 2018 alongside the mu-X Luxe Edition and the D-Max X-Series.
