Cadillac's two-seat V8 convertible gains steering-linked xenon headlights and a high-power V model for 2006. XLR shares a basic structure and plastic composite body panels with the Chevrolet Corvette, but has unique styling, a power-retractable hardtop, and different suspension tuning. The base XLR has 320 hp and a 5-speed automatic transmission. Added for '06, the supercharged XLR-V has 443 hp and a 6-speed automatic. Both come with traction/antiskid control, run-flat tires, and GM's automatic-adjusting Magnetic Ride Control. XLRs have heated/cooled leather seats, wood interior trim, and side airbags covering head and torso. A dashboard screen displays navigation and audio functions. Also standard are adaptive cruise control and keyless locking and engine start.
