The Rivian and Volkswagen Group Technologies joint venture brought one of its new software-defined test vehicles to Sweden and Germany to see how it handles the cold. They stress-tested the all-wheel drive system and validated over-the-air software functionality, amid other tests. Most importantly, the completion of these tests bring Rivian a step closer to receiving the next tranche of investment from VW, which will be crucial as the automaker ramps up its R2 production.
