SAN FRANCISCO : Hyundai Motor unveiled its first three-row electric SUV on Wednesday, pushing into a market for big family cars that global automakers hope will one day be a profit powerhouse. Hyundai's IONIQ 9 will roll out in the United States and Korea early next year with a range of more than 300 miles, the Korean automaker said in a statement. Launches in Europe and other markets will follow, it said. Three-row SUVs have replaced minivans and station wagons to become the big car of choice
