The standard 5.5-liter engine is stroked and bored to 6.3-liters, and gets a full porting treatment, special camshafts and bigger turbochargers. All that engine work pays off with a 0-62 mph time of 4.0 seconds. Pretty damned impressive for a two-ton sedan! Top speed is restricted to a modest 211 mph.
21-inch wheels, monster brakes with 12-piston calipers up front, 6-piston in the rear, an aero body kit, and an uprated suspension complete the picture for the uber-sedan.
