Thanks to its supercharged engine and upgraded components, zero to 60 mph acceleration is achieved in only 4.6 seconds, making the 2006 XLR-V the fastest production model ever produced by Cadillac. Furthermore, lateral acceleration of 0.94 g’s rivals supercars costing thousands more, body roll has been cut by 13 percent, and a 12-percent bump in steering response helps out in those quick S curves. Clearly, going fast in a straight line is only one of this Caddy’s tricks.
