Tesla has unveiled a redesigned Roadster that can climb walls, flip in mid-air and land using built-in thrusters developed with SpaceX. Speaking at a SpaceX test site in McGregor, Texas, Elon Musk said the two-seater can go from zero to 60 mph in under one second and reach a top speed of more than 230 mph. Production is set to begin in 2028, nearly nine years after Tesla’s first prototype was revealed.
