(credit: Nissan) Nissan has agreed to invest $663 million (600 million euros) in Ampere, Renault's electric vehicle operation, the two companies announced today. It's a sign of a renewed alliance between the two automakers that have been in a partnership since 1999, but relations have strained following the 2019 arrest of Nissan CEO Carlos Ghosn. "With the finalization of the definitive agreements, we have entered the next phase of collaboration with Renault and Mitsubishi Motors in mutually beneficial areas of innovations," said Nissan CEO Makoto Uchida.
