Eight more drivers have committed to racing in Formula E, a proposed series featuring electric-powered race cars competing on city courses around the world, the series said Monday.
The drivers include IndyCar Series drivers Sebastien Bourdais, Oriol Servia and J.R. Hildebrand Jr. The others are Bruno Senna of Brazil, Narain Karthikeyan of India, Daniel Abt of Germany, Franck Montagny of France and Christijan Albers of the Netherlands.
Bourdais also was among the trio of drivers who won the Rolex 24 at Daytona endurance race Sunday in the premier prototype class, driving a Corvette prototype for the Action Express Racing team.
Other drivers who already have committed to the Formula E series include IndyCar's Marco Andretti, whose family-owned Andretti Autosport team also has committed to the series.
Formula E plans 10 races over several months starting with a race in Beijing in mid-September and ending with a race in London in mid-2015.
The sixth race is scheduled for Los Angeles on Feb. 14, 2015, although the race's exact location in the city has yet to be determined.
The cars would be roughly similar in size and shape to those in the IndyCar Series. Formula E also is sanctioned by the FIA, the governing body of the Formula One racing series.
