According to Mercedes-Benz diesel engines are in good health and recommended. Suppose without complexity that gasoline engines continue to win the ground – not to mention the electric … – The German brand, however, believes that diesel technology continues to have a future. That is why the Stuttgart-based brand has upgraded the well-known Renault 1.5 Diesel engine (K9K series) to equip its new Mercedes-Benz Class A 180d (W177 generation). This engine with the code name OM 608 thus goes into a renewed range of engines: OM 654 (from the Mercedes-Benz E220d class) and the OM 656 (from the Mercedes-Benz S-Class 400d). Without forget about the new Mercedes Diesel Plug, we have already talked about it
We have made this article considering the request requests that have come to us – because of this article that continues to add thousands of views. NOTE: The following lines will be intended for the technical characteristics of the OM 608 engine, so if you only want to know what the differences between them make sweeps for the end of the article.
Renault / Mercedes-Benz. Is everything the same?
The answer is no. And with this we do not say that the OM 608 (Mercedes-Benz) engine is better than the K9K (Renault) engine, or vice versa. This is not what this is about.
Due to economies of scale (use of shared components within the same brand) or because of the differences in character that each brand defines for its engines, there are characteristics that change from one model to another. model.
The Mercedes Volkswagen Group's engines take different e-management maps depending on the brand – even if final figures are not changed. 19659009] Picture of one of the versions of the Renault 1.5 dCi engine (version K9K 846).
Return to the engine deriving from this article, its code name is "OM 608". This is a development of the "OM 607" engine that we already knew from the previous generation of the Mercedes-Benz A class (W176). In this new version, the power of the 1.5 liter Diesel block has increased by 7 hp, which is now 115 hp (85 kW) at 4000 rpm, while the maximum torque now stands at an interesting 260 Nm at 1750 rpm
Sufficient values to increase the new Mercedes-Benz Class A 180d (W177) from 0-100 km / h to 10.5 and exceed 200 km / h of the maximum speed (202 km / h). In terms of consumption, the brand announces 4.1 l / 100 km in combined cycle and 108 g / km CO 2 values already according to the WLTP cycle.
How did Mercedes-Benz reach this emission value? Use an EGR closer to the engine (with high and low pressure circuit). The exhaust gas selective catalytic reduction system with AdBlue – you can learn more about these systems here – have kept the infamous emissions NO x under control.
Let the differences (finally!)
Unfortunately for the long introduction, it's important to get to the bottom of the problem. Motor vehicles are often a "hot topic" in the automotive industry and we do not want to be fooled.
Mercedes-Benz develops six differences in the OM 608 compared with the latest generation of the well-known K9K by Renault.
- Engine Support
- 7G-DCT (Mercedes-Benz) Double Coupling
- Specific Bass Wheel
- Starting / Stop System
A Strategic Alliance
With Mercedes-Benz and Mercedes-Benz
- Mercedes-Benz and Mercedes-Benz
- Generator and air conditioner compressor. You know, the strategic partnership between Daimler (Mercedes-Benz) and Renault-Nissan-Mitsubishi Group does not stop with diesel engines – known by 180d in Germany and 1.5dCi in French. Even the M 282 engine a four-cylinder gasoline with 1.33 liter capacity, is another visible face of this strategic partnership. I will ignore the production of commercial vehicles and Renault Twingo / Smart ForTwo in the hope that nobody will remember them, okay?
] Produced at the Mercedes-Benz factory in Kölleda (Thuringia, Germany), this 1.33 liter engine was premiere of Renault Scénic and Grand Scénic, and will now equip the Mercedes-Benz A200 class.
develops 163 bhp power, 250 Nm maximum torque and has a roll coating process similar to that used in the Nissan GT-R VR38DETT engine. A process called NANOSLIDE.
Thanks to this process, it was possible to reduce the internal friction of the engine and to optimize heat transfer, two factors with a very positive impact on the efficiency and efficiency of the engine.
But let's finish this article – because the text is already (very) tall and I think it already gave to understand that there are differences between the engines despite the division between the brands. We have talked about the case of Daimler and Renault-Nissan-Mitsubishi Alliance, but there are no examples.
Like it or not, component sharing has been a constant in the automotive industry and for the most part, the biggest recipients have been us, the consumers. I tell myself that in over 400,000 km I was a lucky owner of a Volvo V40 1.9d CR (2001). A model, as you know, despite Volvo's emblem, had a Japanese (Mitsubishi) platform and a French (Renault) engine.
Engine sharing is a hot debated issue among car lovers, in addition to the issue of electric motors Vs internal combustion engines . In these particular cases, opinions tend to be extreme, and arguments are often not based on misconceptions.
Here are some examples:
