London will host the season finale of the all-electric Formula E series in July next year with a doubleheader of races starting and finishing indoors at the ExCel center in Docklands.
The return to London after three years was announced by Formula E chairman Alejandro Agag at the Geneva Motor Show.
The ePrix on July 25-26 will have an indoor stadium section as part of a 2.4-kilometer clockwise circuit taking in the waterfront of the Royal Docks and streets around the center in East London, which hosted events at the 2012 Olympics.
The return "extends beyond pure racing excitement," Agag said. "It's also a strong message for London to tackle air pollution."
Formula E is based in Britain, but London has been off the calendar since 2016 after a race in Battersea Park led to residents complaining about disruptions.
Agag, a Spaniard, has likened Formula E's absence from London to Real Madrid not playing in Madrid.
The series is in its fifth season, with racing in Hong Kong this weekend.
