The next eight drivers to join Formula E's Drivers' Club have been revealed with Narain Karthikeyan, Bruno Senna, Sebastien Bourdais, Oriol Servia, Daniel Abt, Christijan Albers, Franck Montagny and John R. Hildebrand Jr. showing their support for the new, fully electric racing series beginning in September.
Earlier this month, the first set of eight drivers, including Karun Chadhok, expressed their willingness to race in the FIA Formula E Championship.
The Drivers' Club will allow each member to experience the new fully-electric Spark-Renault SRT_01E Formula E car which recently made its public debut driving along the iconic Las Vegas Strip.
India's Karthikeyan has raced in Formula 1 for Jordan and HRT, as well as testing for Williams F1, and last year won five races in the Auto GP Series.
"Sustainability is the current buzzword in automotive technology, and its application in a gruelling motorsport environment like Formula E will definitely help at many different levels," said Karthikeyan.
"On the racing front as well, the series is breaking new ground by taking the sport to the fans in an unprecedented way across the world."
