How to know if my Mercedes has a Renault engine

Mercedes with Renault engine

La German brand Mercedes It is one of the most recognized in the sector, it is synonymous with premium cars, competing with others such as Audi, Lexus, BMW, Jaguar, etc. However, not all cars from this firm have a German engine, such as some models that They have a Renault engine under the hood. Yes, a Renault engine, just as you read.

It's nothing new for a car to have an engine from another brand., this is quite common in the industry due to agreements or strategies or, in some cases, because a brand simply does not manufacture engines and needs suppliers…

We have seen cases where Bugatti uses a Volkswagen engine (which is also responsible for the engines of Audi, Skoda, or SEAT/Cupra and Lamborghini), or an Alfa Romeo with a Ferrari engine or the same one used by some Opels, an Opel with an Isuzu engine, or a Mini with a BMW engine, or how the DMC DeLorean itself used an engine developed jointly by Renault, Volvo and Peugeot. Or Chrysler with a Mercedes engine, Nissan with a Renault engine, Toyota with a BMW engine in its Supra, Lexus with a Toyota engine, Toyota with a Subaru engine, Smart with a Mercedes engine, a McLaren with a BMW engine, a Lotus with a Toyota engine, Ford with a Volvo engine, etc. And so on and so forth with many more cases... A mess, right? The truth is that when you come from the electronic or computer technology sector, this is quite normal, and you get used to the fact that brand is not the same as manufacturer.

Mercedes-Renault Agreement

Renault Mercedes

Would you be surprised to know that some Mercedes Benz cars hide a Renault heart under the hood? Yes, that's right. Thanks to a strategic alliance established in 2009, both car brands joined forces to develop and produce engines together.

La The main reason behind this alliance was the optimization of resourcesBy sharing engine development and production, both Mercedes and Renault were able to significantly reduce their costs, both in research and development and in manufacturing. This cost reduction directly translated into more competitive prices for consumers, without compromising the quality and reliability of the vehicles.

This collaboration has resulted in a range of Mercedes models, mainly from the compact range, which They are equipped with Renault engines. These engines, both gasoline and diesel,, have proven to be efficient and reliable, meeting the high expectations of the German brand. So, you shouldn't be too worried about it... Now, if what you wanted is a Mercedes car, with a German "pedigree", then you won't find it in these cases.

Remember that the automotive industry is a highly competitive sector with increasingly tight margins. Therefore, to stay ahead and meet the challenges of electrification and digitalisation, automotive brands often establish strategic alliances. These collaborations allow them to share resources, knowledge and technologies, accelerating the development of new products and reducing production costs. And you will see them more and more…

How to know if my Mercedes has a Mercedes engine

Mercedes with Renault engine

To find out if your Mercedes has a Renault engine, it is not as easy as opening the hood and looking for a Renault logo, since it is not. Therefore, it is best to know What engines do they share? these two marks to determine if it matches the specifications of your model.

Renault engines found in Mercedes models do not carry the Renault logo. Although these engines are manufactured by Renault and share technology with other models of the French brand, when installed in Mercedes vehicles, they are fully integrated into the logo of the German brand.

It must be said that Mercedes and Renault share 4 different types of engines:

  • Mercedes with Renault gasoline engine:
    • Inline 4-cylinder turbocharged engine with 1.3-litre displacement. *(also present in plug-in hybrids)
    • Block 0.9 TCe.
  • Mercedes with Renault diesel engine:
    • 1.5 liter dCi block.
  • Mercedes with Renault electric engine:
    • 100% electric EQ range.

If your specifications match any of these engines, you could have a Renault under your bonnet. To be on the safe side, in the following section I show a list of all the models that are still sold with these Renault engines.

Mercedes GLB AMG Line

For your peace of mind, we would like to say that currently the only models that are still being sold with a Renault engine are those with an 82 HP (60 kW) electric motor present in the Smart EQ ForTwo and EQ ForFour, which use the same engine as the Renault Twingo ZE and other Nissan and Dacia models belonging to the French brand. Therefore, these Smarts do not have German mechanics, but French ones. So, if you have bought one thinking that they had a Mercedes engine, the truth is that this is not the case.
