Those wanting Jaguar’s top-of-the-line two-door in drop-top form are now getting their wish as the company has officially unveiled the XKR-S Convertible ahead of its official debut at the Los Angeles Auto Show. The convertible features the same supercharged 550 horsepower 5.0-liter V8 found in the coupe, making it the most powerful rag-top that Jaguar has ever built. It’s also the fastest, with the XKR-S sprinting from 0-60 mph in just 4.2 seconds. Funk Flex
