2008 Cadillac XLR Roadster's bold exterior hints at the power and innovation that lies beneath. With its advanced 4.6L Northstar V8 VVT (Variable Valve Timing) engine, XLR is a refined powerhouse. Driver Shift Control transforms the XLR six-speed automatic transmission into a clutchless manual, allowing manual shifts with little more than a tap. Magnetic Ride Control automatically adjusts the ride of your vehicle. Automatic ride control is achieved through a computer used to control and monitor the suspension system. StabiliTrak engages brake and powertrain systems to help keep the vehicle on track when it's not responding appropriately to driver steering input. Within XLR, contemporary eucalyptus wood accents, Bvlgari-designed gauges and striking aluminum accents combine to provide a luxurious and inviting environment. At the touch of a button, the hardtop retracts, letting you experience the pure exhilaration of open-air motoring.
