New Mercedes A-Class Now Available With Renault-Sourced Diesel

Mercedes-Benz has expanded the fourth generation A-Class family with the introduction of the A180d.

The model is powered by a turbocharged 1.5-liter (1,461cc) diesel engine, made by Renault, and it’s essentially the same unit used in the Dacia lineup, bar the different ECU, alternator, AC compressor, start/stop function and some other parts.

It comes with a slight power bump and delivers 116PS (114hp / 85kW) and 260Nm (192lb-ft) of torque to the front wheels, through a dual-clutch seven-speed automatic transmission. That’s 16PS (16hp / 12kW) and 20Nm (15lb-ft) of torque more than what you’d get in the new Dacia Duster dCi 110.

Mercedes-Benz claims the A180d needs 10,5sec for the 0-100km/h (0-62mph) acceleration and has a top speed of 202km/h (126mph). In this flavor, the A-Class burns 4.1-4.5 l/100 km (68.9-62.8 UK mpg / 57.4-52.3 US mpg) on average and emits between 108 and 118 g/km of CO2.

Dubbed the OM 608, it’s already available in Germany, for a starting price of €31,395.15, which equals $37,315 at the current exchange rates, tax included. Besides meeting the Euro 6d-TEMP A emission standard, and being more powerful than the unit used in the previous-gen A-Class, this engine is also cleaner and quieter – the automaker states that it comes with an SCR catalyst with AdBlue exhaust fluid.

The new Mercedes-Benz A180d follows the introduction of two other diesel engines: the four-cylinder OM 654 in the E-Class and the six-cylinder OM 656 in the S-Class. This sends a clear message that the German car brand won’t ditch oil burners anytime soon.

    Cool, but that 1.5 Renault diesel is known for It’s lack of reliability.

    • Christian Wimmer

      Early versions were a little problematic, but they worked out the kinks and that engine is now considered very reliable. You will find many owners on A-Class forums who have gone over 200,000 km with these engines without issues.

      Something to keep in mind is that modern Diesel engines are only going to be reliable if they are driven for long distances. As I understand it, a diesel needs longer to reach its optimal operating temperature, but more critically all of these new anti-pollution systems (DPF in particular) can clog and fail if these cars are continually driven for only short distances. When the DPF fails, the engine can suffer problems as a result. This is my understanding of the situation.

        Most of 1.5 dCi users known by me are having problems with these enginges even in new Megane. I don’t want to generalize but my own experience tells me to avoid this engine. It may only be bad luck but this is how i see it. Overall about diesiel engines you are right, but I’m driving VW’s 2.0 tdi and 1.6 tdi mostly in town area and after making with them more than 200k kilometers they are still fine, no faults. Problem with current engines is amount of variants of one unit. One type of 2.0 tdi may live for years but other one will fail before your wife will know that you bought new car.

          I know this is my experience only but have had a Laguna 1.5 dCi for 7 years, 98K miles, never had any problems whatsoever with engine (or anything else actually, except for A/C last year)

  • Evo45

    Umm, it would be 6 HP increase. It was 110 HP at first, so that’s incorrect.

    • dufonrafal .

      Yep, last time I checked 116-110=6 not 16 🙂

    “New Mercedes A-Class *Now* Available With Renault-Sourced Diesel” O.O !?!?
    Who the hell post this news?
    For what I know Mercedes its being using that engine since the previous versions of the A, B, C, CLA, GLA Class 160d’s, 180d’s and 200d’s and the CITAN which is nothing more than a rebadged Renault KANGOO/Dacia DOKKER.

      Wrong! Its a newly developed engine. Also – and no one gets that right – Mercedes is NOT buying a Renault engine. The engine is developed in a cooperation of Mercedes and Renault. Additionally the Mercedes version of the engine uses other – higher quality – parts and functions that the Renault version don’t use. Its not a rebadging.

  • Miguel Candelario

    The basic engine is identical to the Renault K9K engine. Among Mercedes-specific components include the start-stop function, the ancillaries ( air conditioning compressor and generator ), a special dual-mass flywheel, a modified engine control unit with additional features and exhaust aftertreatment.
    In comparison to its predecessor, the height of the aluminum cylinder head was reduced and the intake manifold integrated into the cylinder head cover. The charge cycle is controlled by two valves per cylinder and an overhead camshaft ( OHC valve control ).

    If there is any emissions cheating found, Mercedes blame now Renault.
