A 5.5-liter biturbo V-8 outputs a thunderous 550 hp and 531 lb-ft of torque. While it bears the signature of the single technician who crafted it by hand, it's a high-tech powerhouse. Twin turbochargers spin up to 185,000 rpm to dramatically boost low-end torque. High-pressure Direct Injection and rapid-multispark ignition respond with millisecond speed. Along with remarkable efficiency, ultralow emissions, and everyday smoothness, it delivers 60 mph in a breathtaking 3.6 seconds.
