Two of the best Detroit debuts are two of the best performance saloons, Maserati Quattroporte Sport GTS and Jaguar XFR. Two great looking rides with big V8s! True petrolhead’s cars! The Masser comes with some visual tweaks like LED lamps and a Granturismo grille to make it look more sporty and uses a 4.7-liter V8 engine with 439hp! This is certainly one of the coolest cars money can buy. On the other corner there is Jag XFR which is less than a week old but despite that has accomplished quit a lot! Recently it hit 225mph at Bonneville and became the fastest Jaguar in history. It has a supercharged V8 with 510 horsepower. So we prepared a mixed gallery containing live images of GTS and XFR for you to enjoy! Click the jump to see it…
