As had been unofficially anticipated, Nissan will be revealing the 2018 Leaf in September.

The occasion will be an event prior to the Tokyo Motor Show which takes place the same month, and the specific date according to a tweet today is Sept. 6.

Nissan is credited with selling the most EVs since its inception with more than a quarter million delivered, and for kicking off the modern major-manufacturer EV era.

Its CEO Carlos Ghosn was widely quoted as very bullish on the future of electric vehicles, but the long model run of the car released in Dec. 2010 has left some scratching their heads, and some have lost confidence Nissan is as serious as it once let on.

Whether such doubts are warranted is questionable, though to be sure they did milk it longer than General Motors did the first-gen Volt, which was released the same month, and whose second-generation was first shown Jan. 2015, and which went on sale last fall.

The Leaf began life in the U.S. with 73 miles EPA-rated range. In 2013 updates to its system, while leaving the 24-kWh battery capacity intact, saw its range with full battery rise to 84 miles. In 2016 a 30-kWh pack was introduced for 107 miles.

As for the new model, it’s rumored that it will get two battery options, and only the smaller of the two will be for sale for year one. It’s not believed the battery will be liquid cooled, but the car is being redesigned for a more mainstream look.

Rumored also is fast charging capability of as much as 150 kW.

The Leaf will enter the market against the 238-mile Chevy Bolt EV, which starts at $37,495 before a $7,500 federal credit.

It will have the basis for semi-autonomous driving, and Nissan intends to expand that capability in coming years.

Nissan also benefits from years on the market, and EV fans will hope it folds in more lessons learned for a much-improved car.
