Daimler, Audi, BMW, Porsche and Volkswagen have announced that they will drive the development of CO2 (R744) technology in Mobile Air-Conditioning (MAC) systems. However, out of the manufacturers’ group, only Daimler development chief Thomas Weber is quoted as saying “We are delighted that we were able to agree on this sustainable and safe solution together with Audi, BMW, Porsche and Volkswagen, with the involvement of the VDA.”
Daimler regards the technical challenges for developing MAC systems for high-pressure CO2 technology to be “manageable”. In Geneva Weber told journalists that for safety reasons 1234yf, so far favoured by the automotive industry, would not be considered an alternative and “for this reason we have clearly tasked our engineers to develop a CO2 MAC system.”
