Four more drivers named to Formula E Drivers' Club

Four more drivers have been named as part of the inaugural all-electric FIA Formula E Championship's 'Drivers' Club' to bring the tally to twenty drivers who will be drafted among the ten teams that are participating in the new motorsport championship.

India's Karun Chandhok and Narain Karthikeyan had been included in the Formula E Drivers Club this January, which will now feature former Formula 1 drivers Jarno Trulli, Nick Heidfeld and Jerome d'Ambrosio along with Mercedes AMG F1's test and simulation driver Sam Bird.

Trulli is the third most experienced F1 driver in history by race starts, tied with Ricardo Patrese behind only Michael Schumacher and Rubens Barrichello. His participation in Formula E is in keeping with the trend of former F1 drivers signing up for the championship.

Currently Audi Sport ABT are the only Formula E team to have announced its final driver line-up for the season with Daniel Abt and Lucas di Grassi set to pilot their vehicle in the ten round championship that will kick off in Beijing on September 14.

India's Mahindra Racing is among the ten Formula E squads that will participate in the city-centre based championship that will see races being held on street circuits in high-profile metropolitan cities rather than traditional circuits, at least for the first year of the championship that will run from September 2014 to June 2015.
