Le Mans 24 Hours: Nissan ZEOD won't try electric lap in qualifying

Nissan will not attempt an all-electric lap of Le Mans with its experimental ZEOD RC racer before the 24 Hours starts on Saturday

Le Mans 24 Hours: Nissan ZEOD won't try electric lap in qualifying

The Japanese manufacturer has so far been prevented from trying to complete a lap of the 8.47-mile Circuit de la Sarthe on battery power at either the test day on June 1 or during practice and qualifying on Wednesday.

Fuel pump and exhaust manifold issues limited the petrol-electric hybrid to 24 laps at the test, before an input shaft failure in practice and then three red flags in qualifying prevented the car from completing any laps.

The lack of running means Nissan and technical partner RML are behind in their programme and will only run segments of the lap without the car's three-cylinder petrol turbo engine engaged during Thursday night's pair of two-hour qualifying sessions.

Nissan global motorsport boss Darren Cox told AUTOSPORT: "We won't go for a full lap tonight, but we will be doing big portions of the lap on electric power."

The ZEOD has run for more than 8.5 miles with its three-cylinder petrol turbo engine switched off during testing, however.

It ran for 11.9 miles around the Bruntingthorpe proving ground in Leicestershire the week after the test day.

But Cox stressed that was no guarantee that the ZEOD petrol-electric hybrid would achieve its target of an all-electric lap during the race.

"That's 19km around a much slower circuits; here we have much longer straights that sap the power," he said.

"We need to know how far to push the battery without damaging it - it is like over-revving a conventional engine.

"We have to build up to it slowly and that's why we will only be doing portions of the circuit on electric power tonight."

Nissan has a series of targets for the ZEOD, which is driven by Lucas Ordonez, Wolfgang Reip and Satoshi Motoyama: a lap at GTE Am pace and a 300km/h (186.4mph) top speed on the Mulsanne Straight on battery power, and a petrol lap at LMP2 pace.

The standout memories of Le Mans 2021

OPINION: With four of the five Hypercar entries unproven in a 24-hour race, it would not have been unexpected for at least one of them to suffer serious reliability trouble. That they all managed to make it through the race relatively unscathed, says GARY WATKINS, was something of a surprise.

How overlooked Mazda produced one of Le Mans' greatest shocks

The screaming rotary-engined Mazda 787 is regarded as one of the most popular Le Mans 24 Hours-winning cars, but until its surprise success on this day 30 years ago it was never regarded as a likely victor. But that reckoned without a new technical partner, some canny political manoeuvring and a rival's bizarre self-inflicted weakness

One more would put him level with his nation's favourite son, but there's another prize he would value far more than the honour of matching Juan Manuel Fangio's tally
