Jaguar is promoting its latest XF Sportbrake with a new custom-made speedboat.

Jaguar has plunged into the boat building business to create a one-of-a-kind speed boat to show off its latest XF Sportbrake. Like all of Jaguar's cars, the design of the boat - officially called the Concept Speedboat - was lead by Jaguar Director of Design, Ian Callum.

Although far from the brand's typical line of work, the 20-foot Concept Speedboat features a number of design cues from Jaguar's storied past. For example, the carbon fiber fin that runs the length of the boat was inspired by the iconic Jaguar D-Type. Even the look of the boat's fuel filler cap is intended to mimic the design of the unit used on the Series 1 XJ.

"We recognize that both our existing and future customers enjoy diverse and active lifestyles," Callum said. "With the launch of the new Jaguar XF Sportbrake, we had an opportunity to create a vision of how our design philosophy might be applied to an alternative product, in which speed and beauty are also priorities."

"The Concept Speedboat looks powerful. It follows, in so many ways, the idea of a traditional speedboat but with the sleek and fast characteristics that you would expect from a Jaguar Car."

Thanks to an available 275 horsepower, 443 lb-ft of torque 3.0L diesel V6, the Jaguar XF Sportbrake can tow up to 4,000 pounds. However, Jaguar failed to mention what engine powers the Concept Speedboat.
