Our Royce Dawn roars through the streets with its 6.6-liter V12 engine that outputting 563 hp (575 lb-ft of torque) and capturing the attention of everyone in its presence. However, when really pushed to its limits it can hit 60 mph in just above four seconds, accompanied by its deep grumble, all thanks to its custom-tuned exhaust system. Class and elegance are symmetrical when it comes to the Rolls Royce Brand, so you can expect nothing less when you decide to roll with Rolls Royce.
