The 3 prototypes of the Audi RS Q e-tron E2 that will race the Dakar 2023 will use, for the range extender, a special renewable fuel. To report this interesting novelty, the car manufacturer directly which also provided a few more details of this special fuel. We remind you that the tender will start on December 31st and end on January 15th.
REDUCTION OF CO2 EMISSIONS
To reduce carbon dioxide emissions, the German automaker relies on products based on plant residues, with no impact on the food chain, obtained by converting biomass into ethanol and subsequently refining the semi-finished products. The final fuel is called ETG (ethanol-to-gasoline).
Audi says that fuel will find a place inside the tank of the electric prototypes made up of 80% sustainable components, including ETG and e-methanol. Thanks to this petrol, the house of the 4 rings declares that they are going to reduce carbon dioxide emissions by 60%. compared to using a traditional racing fuel. The Audi reFuel complies with the stringent specifications of the FIA and ASO regulations.
The chemical characteristics are similar to those of commercially available 102-octane gasoline. Such a high octane value favors the anti-knock properties of the air-fuel mixture. Thanks to this innovative solution, the combustion engine can count on a slightly higher efficiency compared to petrol of fossil origin. At the same time, the high oxygen content characteristic of Audi reFuel reduces the energy density of the fuel; reason why the Audi RS Q e-tron E2 is equipped with a larger tank than the previous generation of the electric prototype with range extender.
We recall that the range extender of the electric prototypes from Audi is a four-cylinder TFSI – direct injection turbo – derived from the DTM, the German Touring Car Championship. The powertrain features a scheme with three electric units: two MGUs (Motor Generator Units), one at each axle, take care of the traction, while a third unit acts as a generator to help recharge the high voltage battery.
Audi aims to complete the world’s toughest rally raid using only the new renewable fuel. Oliver HoffmannAudi Board Member for Technical Development, commented:
Audi’s decarbonisation strategy is mainly based on the introduction of a wide range of fully electric cars certified carbon neutral and on the use of both renewable sources and the closed cycle of materials. Complementing this, renewable fuels offer the possibility of sustainably powering internal combustion engines. The Audi RS Q e-tron is the emblem of this approach and now combines electric propulsion with the use of an innovative green fuel.
