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.
