Jaguar and Mercedes have had enough of watching the Porsche 911 dominate the high-performance sports car market. It's just gone on for far too long. And it must end. Perhaps it will, perhaps not. But whatever the sales numbers and prestige factor ultimately turn out to be, there's a new player in town and it's called the Mercedes-AMG GT S. The successor to the beloved SLS AMG is powered by a twin-turbo V8 that spits out 503 horsepower.

Not to be outdone, the Jaguar F-Type R Coupe comes with its own bad ass ammo: a blown 5.0-liter V8 with 567 hp. To compare, the 911 Turbo and Turbo S produce 513- and 552-hp, respectively. Still, the 911 Turbo has proven itself time and time again. Can these two newbies dethrone the so-called quintessential daily supercar? Does the fact that neither offers AWD (yet) matter? And what about styling? Does the AMG GT look better than its two main rivals? Or did Mercedes not do enough? Let us know your thoughts in the comment section and poll ahead.
