The Super V-8 is the top-of-line model for the XJ family of full size sedans.  The Super V-8 also brings the largest increase in price between any two XJ models.  With a base price over $10,000 above the high performance XJR, a fully equipped Super V-8 approaches six figures.  Nothing is new for this model in 2007.
With the Super V-8, Jaguar attempts to combine all of the super performance features of the XJR with all the super luxury accouterments of  the Vanden Plas.  The Super V-8 is also built on the longer 125 inch wheelbase.  Features include 19 inch wheels, wider tires, "R-Performance" brakes, radar-apative cruise control, four zone climate control, navigation system, front and rear park control, a two-screen rear seat DVD entertainment system, and the fold-down picnic tables.  Essentially, anything found in any other XJ is here, and standard.  All of the exclusive Super V-8 inclusions are optional on both the XJR and Vanden Plas.
The Super V-8 uses the same power supply as the XJR: a supercharged 4.2 liter aluminum block V-8.  This is the only XJ over 4000 pounds, but that does not impede upon acceleration. The 400 horsepower and 413 pound-feet of torque help launch the Super V-8 from 0 to mph in five seconds.
