Cadillac XLR uses the Cadillac Northstar engine rather than the GM LS2 engine found in the Corvette. The XLR also has its own unique styling, interior, and suspension, and has a power-retractable aluminum hardtop. The engine is Cadillac’s 4.6 L Northstar tuned for 320 hp, mated as of the 2007 model year to a 6-speed automatic transmission.
Cadillac XLR is a luxury roadster sold by the Cadillac division of General Motors and is assembled in Bowling Green, Kentucky. It is based on the same Y-body platform as the Chevrolet Corvette. Cadillac XLR Platinum features exclusive 15-spoke, 18-inch wheels, with a brighter chrome finish for the grille and an exclusive Liquid Amethyst exterior color and exclusive Platinum badge of a supercar.
