Just four years into its development, Formula E has announced a "groundbreaking" multi-year partnership with Swiss industrial technology giant ABB.
The annual motorsport series will be renamed the "ABB FIA Formula E Championship" -- the first time an FIA-sanctioned single-seater championship has had a title sponsor.
As the third E-Prix of 2017/18 approaches in Marrakesh, Morocco, Formula E chief executive Alejandro Agag called it "an historic day" for the series he founded in 2014.
"This is probably the biggest announcement that Formula E has made ever," Agag told CNN Sport during an announcement at the Saatchi Gallery in London Tuesday.
"We share the same goals. ABB is a company that is focusing on new technologies that are going to transform mobility in the world, and that's what we want to do."
