It's alive and it looks encouraging.
According to the description, it's the first time when the car is running under its own power from a 800 V production battery, developed in partnership with Williams Engineering.
"A moment of @astonmartin history. First Validation Prototype Aston Martin RapideE moves under its own power for the very first time with its breakthrough 800v battery. Great work from the development team which includes Williams Engineering."
The first electric Aston is to be available before the end of this year, but only 155 units will ever be made.
