As I turn the key in the ignition, the big 4.6-liter V8 turns over and actually rocks the car from side to side as it roars to life. And does it ever roar!
So often I complain about how muffled the exhaust note is on high performance cars, but that is not the case here. Even at under 3000 rpm it draws stares and gives its owner a sonorous treat. Whether it's popping and snarling on a high rpm downshift or just rumbling like distant thunder as you crawl along in traffic – this V8 is a treat to the ears.
And it does more than just sound powerful; the Mustang's V8 generates 315hp at 6000 rpm and 325 ft-lbs of torque at 4250 rpm. In total, that's 15 more horsepower and five more ft-lbs of torque than the previous model, which is achieved through a more efficient air intake system, as well as a 250 rpm increase
