Neither Chandhok nor Senna are strangers to the international racing scene, having both competed in Formula One. Representing the only Indian team in the world's first fully-electric racing series, Chennai-born Chandhok and Brazilian Senna bring with them a strong working relationship, having already raced as team-mates previously in their careers.
SP Shukla, Chairman of Mahindra Racing, said: "Both Karun and Bruno come with very strong racing pedigrees and have successfully competed in a variety of racing series over the past few years. The entire team looks forward to working with both of them to optimise the performance of our racing car over the next few months of testing before the start of racing in September this year."
To date, six of the 20 drivers (two per team) have been confirmed with Lucas di Grassi and Daniel Abt signing for Audi Sport ABT, in addition to Jaime Alguersuari and Sam Bird, who join Virgin Racing.
Racing entirely on temporary city-centre race tracks, Formula E uses cars capable of speeds in excess of 150mph (225kph).
The first of 10 races takes place in Beijing around the iconic Olympic 'Bird's Nest' Stadium with the season finale taking place in London on June 27.
