New reference architecture for AV connects real-world fleet data to simulation, training, and validation. The collaboration is expected to reduce repeated physical test drives by up to 90% and shorten AI regression test cycles by up to 85%. BERLIN, Oct. 21, 2026 /PRNewswire/ -- At NVIDIA GTC Berlin, Porsche, Volkswagen Group brands, and CARIAD announced that they are jointly building a shared AV data flywheel, with Porsche leading the initial implementation and ecosystem integration together with NVIDIA, Microsoft, and Voxel51. With a fleet generating data equivalent to 11,000 average drivers per day, the Volkswagen Group is leading the development of a physical AI stack that connects fleet data to simulation, training, and evaluation.
