From January through July, Fiat (F:IM) sold 392,390 Jeeps in North America, 44 percent more than in the same period last year. That was enough to rocket the American brand past Kia (000270:KS) and Dodge, its corporate cousin, to the No. 7 spot on a ranking by volume. At the moment, Jeep is right behind Hyundai (005380:KS) in terms of total vehicles sold. If all the car companies were to maintain this years pace (granted, a huge if), Jeep would become the best-selling vehicle brand in North America sometime in 2018, blowing past Ford (F) and its fleet of aluminum F150s
