Nissan North America has extended its $10,000 rebate on the all-electric Nissan Leaf car in Hawaii.

Hawaiian Electric Co. announced today Nissan extended the rebate to June 30 for electric utility customers on Oahu, Hawaii Island and in Maui County. Nissan and HECO originally announced the promotion on Jan. 25. Under the first offer, customers had to have deposits down by the end of March and the car had to be delivered in April to qualify.

The $10,000 discount off the Leaf’s sticker price, when combined with federal tax incentives, resulted in some customers being able to save up to $17,500 on 2016-2017 Nissan Leafs. The tax credit varies for EV owners dependent on how much they pay in taxes. An EV owner can’t spread the tax credit over multiple years and it is not refundable.

The manufacturer’s suggested retail price for the 2017 Nissan Leaf is $30,680.

HECO said customers should take their electric utility bill and the promotional flyer at hawaiianelectric.com/nissanleaf to participating Nissan dealers. HECO said the deal will run as long as supplies last.

Nissan is paying for the rebate, not electric customers, according to HECO. The utility’s only responsibility is to notify customers of the deal.
