The mid-life-update of the Isuzu D-Max, due in 2016, will see the Thai-built ute replace the current Euro4-rated 3.0-litre single-turbo diesel engine, with a 2.5-litre twin-turbo unit to meet Euro5 emissions regulations in Australia.

The new Isuzu engine is already used in the Isuzu D-Max in parts of Europe including the UK, where Euro5 standards have been in place for several years.

While the smaller displacement twin-turbo unit gives up 10kW of power to the existing 3.0-litre powerplant, maximum torque is up by 70Nm to 400Nm between 1400-2000rpm.

It’s a comprehensive re-design by the company’s powertrain development team, with the two engines sharing similar physical proportions but the 2.5-litre unit getting a shorter stroke and a boost in direct-injection pressure from 1800-2200bar.

It’s also one of the cleanest powertrains in the light commercial segment, achieving a claimed fuel-economy of 6.2L/100km (4×4 manual models) and CO2 emissions of 194g/km. By comparison, the existing Isuzu 3.0-litre engine produces 220g/km of CO2.

    torque will go up 20nm in this country, not 70.

      Why din’t we get it from the start ?

    Although I’ve seen more Colorados, I think this is the better looking and better value rig.

    This has only been out 5 minutes & they are already saying what engine it will get in a couple of years. 

    And yes, why wasnt it made available from the start

      I think that you’ll find that the 3 litre is better due to its wider spread of torque, so while its legal its the preferred choice by Isuzu. I assume that its easier to meet euro 5 and 6 with smaller engines and that’s why manufacturers are downsizing. As for durability, well that’s a question for another day. Perhaps Renault-Nissan would like to comment….

        maybe vw (amarok) as well?…

  • save it for the track

    And Ford with the Ranger. Anyone else know of oil issues and engines blowing up?

       er NO.

  • save it for the track

    ears to the ground…

    I see this in trucks I sell. Smaller motors to meet emissions with more boost while giving up the durability of the larger motor with the better torque range. Sad days indeed.

    The current 4JJ1-TC engine is excellent and used in Isuzu light trucks operating up to 8 tonnes GCM.  Compared to similar engines offered by other makers it is a sledgehammer,  not jst a rubber mallet.

    i have the chevrolet d max II 2.5 twin turbo 2015 ute. Only had problems so far. Blown the twin turbo three times and the ute only has 11300 km chevrolet does not have an answer and will have to replace the ute, purchased three months ago. Also leaking water all through the passenger leg space from air conditioning and also onto the second touch screen radio.

    Isuzu tells me its because of those items being fitted pfft joke really !!

    • asd

    Hi Anthony Crawford how accurate is the above info??? My source at Isuzu Ute Australia tell me that Australia might be the first country in the world to get a Euro5 3.0L 4JJ1 motor? After doing 21000 units in 2015 in Australia Isuzu Ute Global are trying hard to get the 4JJ1 to Euro5 with the R&D also being shared for the truck manufacturing side of things too. No changes are planned till the very end of 2016 Nov-ish to ensure maximum time to see if they get the 4JJ1 across the line for Euro5.
