With the CTS-V already burning up the streets with its Corvette-sourced V8, Cadillac has turned its attention to the XLR for V-Series treatment. Instead of an LS6 V8, however, the XLR-V is expected to get a supercharged version of its standard 4.6-liter Northstar V8. A full complement of performance enhancements such as larger wheels and tires, recalibrated suspension and stronger brakes should round out the package giving Cadillac a serious performance entry in the luxury convertible segment.
