Cadillac's last modern convertible design as of 2015 was the 2009 XLR that featured a powerful V-8 engine and the same mechanical platform as the Chevrolet Corvette. Cadillac discontinued convertible production after 2009 and does not have a convertible in its line of vehicles as of 2015.
The Cadillac XLR, which was produced from 2003 to 2009, featured a retractable hardtop and seating for two. Initially fitted with a 4.4-liter V-8 engine, the 2009 model received a 4.6-liter engine producing 320 horsepower and 310 foot-pounds of torque directed to the rear wheels through a six-speed shiftable automatic transmission. Despite using the same platform as the C5 Corvette, the XLR was not generally considered a sporty automobile due to its chassis and suspension tuning favoring comfort and ride quality over agility and cornering performance. Eight-way power-adjustable leather seats were standard equipment on the XLR, as were an Alcantara dash, wood accents and revised exterior elements on the 2009 model.
Cadillac has shown at least one convertible concept car since the XLR was discontinued. Known as the Ciel, this vehicle appeared at car shows in 2011 and featured four seats as well as a hybrid drivetrain. However, Cadillac decided against releasing a mass production version of the Ciel.
