Formula E, season 1, was effectively a single make formula. All parts, including drive trains, were fixed. This season, inverter, electric motor & gearbox can be designed by the individual teams, but the battery is still controlled.
Perhaps most interesting in season 2, is the number of gearbox ratios used. In the fixed specification season 1, all cars had 5 forward gears. This year, everything from 1 to 5 forward gears is being used by different teams.
Andretti, in their season 2 car, has had problems with software, plus coolant leaks from the gearbox have been shorting out the motors. As a result, they will be reverting to the season 1 drive train.
