 The design process of the next generation of TGVs began in 2016 when SNCF and Alstom signed an agreement to jointly develop the trainsets, with goals of reducing purchase and operating costs, as well as improved interior design.The design that emerged from the process was named Avelia Horizon, and in July 2018 SNCF ordered 100 trainsets with deliveries expected to begin in 2023.They are expected to cost €25 million per 8-car set.
