Speaking with media last week at the New York auto show, Volkswagen of America CEO Kjell Gruner said that sedans and hatchbacks are "always going to be there."Gruner described the Golf GTI and Golf R as Volkswagen's "heartbeat," stating that "you can't measure success and importance just alone by volume."The Jetta, meanwhile, was still VW's third bestseller last year, catering to customers who "don't want the SUV, like the better gas mileage you get with it, don't need the all-wheel drive."
