Olympic triathletes Alistair and Jonny Brownlee have reignited their rivalry in a triathlon with a difference – behind the wheel of a Jaguar XF and XF Sportbrake. The pair competed in a trio of challenges to show off the dynamic performance, increased load space and parking technology of both vehicles. First was the swim, otherwise known as the 'Smartcone Slide', pitting the brothers against each other in a slalom contest on a wet skid pan that proved the outstanding traction and overall performance of the Jaguar XF Sportbrake in low-grip conditions. Round two put the pair on their bikes for 'Pedal to Pack' as they raced to stow their equipment the quickest in the 565 litres of rear load space and on the versatile roof rack of the new XF Sportbrake estate.
