The 556 horsepower CTS-V Sedan. It's the world's fastest production sedan with 0--60 in a blistering 3.9 seconds. Complementing the epic power is a high-performance chassis fitted with the dual-mode Magnetic Ride Control suspension—tuned and perfected on Germany's notorious Nürburgring racetrack—that reacts to changing demands in less time than the blink of an eye in both Touring and Track modes. Bringing it all to a halt is the massive stopping power of 6-piston front, 4-piston rear Brembo® brakes. Of course, true performance design doesn't end under the hood. Available RECARO® performance seating with pneumatic bolster controls provides a firm plant during performance maneuvers. Red LED tracers encircle the tachometer and flash at the approach of redline, while a g-meter communicates lateral acceleration left and right. And Obsidian Black faceplates and available Midnight Sapele wood trim add a high-tech sophistication.
