Aston Martin Valhalla 937-horsepower hybrid supercar The Aston Martin Valhalla is a dramatic 937-horsepower hybrid supercar. Two years after Aston Martin debuted the striking but clumsily titled AM-RB 003 concept, the final production version has arrived with a much simpler name: Valhalla. The automaker revealed the hybrid supercar on Thursday ahead of this weekend’s British Grand Prix, where Aston Martin will compete as a manufacturer for the first time in over 60 years. Aston Martin returned to F1 this year with a team that’s co-sponsored by Cognizant, the professional services firm at the center of Casey Newton’s multipart investigation into Facebook’s content moderation problem. In 2020, the company was taken over by Canadian billionaire Lawrence Stroll, the de facto villain from the third season of Netflix’s Drive to Survive series.
