Nissan is not rushing its decision on its driver line-up for its inaugural Formula E season in 2018/19, says its Global Motorsport Director Michael Carcamo.

The departure of Renault from the series and its replacement to partner the e.dams team by its motoring ally Nissan was announced in October of last year, but Nissan has yet to make any indication on finalising its drivers.

Carcamo explained that the limited testing time has been one of the reasons for this, and a looming powertrain homologation date of October 1 suggests it will not announce its drivers until after this date.

“At the moment we’re taking our time to do the work that we need to do, there’s a lot of preparation that’s gone into development,” he told Formula Spy in New York.

“There’s a lot of simulator work that’s being done. It’s no secret that we’ve had some of our drivers working in the simulator, the problem is there’s limited test time to get our drivers into the real car and make a proper assessment.

“So first thing’s first is we want to develop our powertrain so we make sure we’re ready. The homologation period is a lot sooner than the driver’s announcement, so that’s what we’re focusing on – the powertrain and getting the car right.”

Sebastien Buemi is expected to stay with the e.dams team when Nissan comes onboard having already had a contract in place with the team, despite rumours of a conflict of also racing for Toyota in the World Endurance Championship.

The question of his team-mate remains an open book after Nico Prost revealed he would leave the team at the end of the 2017/18 season.

Jann Mardenborough, currently racing in Super GT, is considered one of the favourites for the seat, but Nissan has others out of a drive following its departure from V8 Supercars.

“You’ve seen what the championship has evolved in to, and having two strong drivers is really critical for a team championship,” Carcamo added.

“Renault e.dams has been very successful in its campaign and we need to too, so that’s the first step is to make sure we’ve got the right driver that’s going to be with us for a while to come.”
