The XLR was a luxury two-seat hardtop convertible derived from the Evoq concept car. Based on the Corvette, the Cadillac roadster is powered by a smooth Northstar V8 mated to a five-speed automatic transmission. At the touch of a button, its roof folds into the trunk, but still leaves room for luggage. The interior is luxuriously appointed, but not as well built as the Eurpoean cars in the same category. While it is undeniably quick, the XLR doesn't feel as sporty to drive as the European alternatives either. However, the performance-oriented, supercharged XLR-V, added starting from 2006, solves that problem. The XLR was discontinued after the 2009 model year.
