"Mahindra Racing have confirmed their withdrawal from the ABB FIA Formula E World Championship qualifying sessions and the Cape Town E-Prix Round 5 due to rear suspension safety concerns.
"A thorough investigation on the suspension elements of the Mahindra M9Electro race cars will take place on the team’s return to the UK.
"This decision also affects their customer team ABT CUPRA, who will also not take part in the remainder of qualifying or the race.
"The safety of the drivers and extended teams is of utmost importance at this point in time."
