Blue gasoline and blue diesel to reduce the impact and carbon footprint of internal combustion engines. While brands such as Porsche continue to invest in the development of 100% neutral fuels, Audi has spent years advocating another no less interesting technology, that of blue gasoline and diesel, also known as Blue Diesel R33 and Blue Gasoline R33.
In the coming years we will have to get used to hearing expressions related to colored fuels. Green or gray hydrogen, blue gasoline, which do not refer specifically to the physical staining of the fuel, but rather to how sustainable the fuel or energy vector is, which is closely related to its origin and the process of production.
Today we also knew that Audi has been using gasoline and blue diesel in its factories for some time and that many of the cars that leave their production lines carry it in their warehouse.
Audi uses blue fuels in its factories, to supply its internal fleet of vehicles and to refuel the necessary fuel in the tank of the cars that leave the production line
Cars leaving the factory with blue gasoline and diesel
For a few years now, Audi has been adapting its range of engines to be compatible with these fuels. In March 2021 I began to use blue diesel at the pumps of the Ingolstadt and Neckarsulm factoriesso that these fuels are not only used in the fleet of vehicles in their factories, but also to keep enough fuel in the tank – the fuel with which a new car is delivered depends on each manufacturer – to deliver the order to the factory to the client.
The brand with the four rings announced these days that They have also started to use Gasolina Azul R33.
Now, what exactly are blue gasoline and diesel?
Since 2021, Audi has been using blue diesel in its factories and has now just introduced blue gasoline as well.
What are R33 blue gasoline and diesel?
Unlike completely neutral fuels, R33 blue gasolines and diesels reduce the carbon footprint by approximately 20%. This reduction in emissions, and the blue color with which they are defined, is due to the fact that only a third of the fuel is of synthetic origin, produced by products of plant origin and residues, which in the process allow these emissions to be saved. COtwo.
- The Gasoline Blue R33 It is made up of 10% oxygenated fuels (such as ethanol) and 23% biogasoline (obtained from residues such as those resulting from the paper pulp industry). The rest of the fuel is of fossil origin.
- The Diesel Blue R33 It consists of 26% renewable paraffinic fuel (HVO, biofuel produced by catalytic hydrogenation of vegetable oils), 7% biodiesel and the remaining 67% fossil fuel.
According to Audi, these blue fuels meet the technical specifications that apply to gasoline and diesel used in modern engines and even in many older engines. Let’s remember that The fuels that we are refueling in Spain are already partially made up of biofuels in a proportion between 7% and 10%. Spanish service stations also have biofuels of larger proportions, which should only be used by cars that are adapted for it.
On the other hand, diesel and blue gasoline are not only available at the internal pumps of the Audi factories, but also at some German service stations.
