While Porsche may be a relative newcomer to the four-door market, Maserati has been making them for decades. But though the Panamera has been made available with a variety of powertrains, the Quattroporte has only ever been available with a V8. But that comes to an end this weekend in Shanghai where Maserati has revealed not one, but two new sedans powered by V6 engines. Most important, of course, is the new Ghibli, which Maserati previewed
just a couple of weeks ago.
