The Jaguar XK was launched in 2007 as a replacement for the 10-year-old XK8. Designed by former Aston Martin chief Ian Callum, the XK received a convertible version for the 2009 model year, one year before the entire lineup received its first facelift. Initially powered by a 4.2-liter, V-8 engine rated at 300 horsepower and 310 pound-feet of torque, the XK Convertible received a larger, 5.0-liter V-8 in 2010. Generating 385 ponies and 380 pound-feet, the new unit remained unmodified until the 2015 model year. Despite lacking powertrain updates, the XK Convertible received many changes inside and out throughout its life, remaining competitive against rivals from manufacturers such as Aston Martin and BMW.
