The 2009 Cadillac XLR gets freshened exterior styling and a few new available features. This two-seat convertible is based on the Chevrolet Corvette, but XLR has unique styling, a power-folding hardtop, and different powertrains. XLR is offered in two trims: Platinum and XLR-V. Platinum replaces the Base model and is powered by a 320-hp 4.6-liter V8 engine. High-performance XLR-V versions have a supercharged 443-hp 4.4-liter V8. A 6-speed automatic transmission is standard on both. Available safety features include ABS, traction control, antiskid system, and front side airbags. Platinum models get new 18-inch wheels. Run-flat tires are standard, along with GM's automatic adjusting Magnetic Ride Control suspension. A wireless cell phone link is newly standard. We have not yet tested the 2009 Cadillac XLR.
