As it rolls out a procession of new products aimed at rebuilding its position in the global luxury market, Jaguar has been riding a tightrope, quite literally, with the first showing of the newly redesigned 2016 Jaguar XF. With movie stuntman Jim Dowdell behind the wheel, the new sedan rolled across a pair of wires strung nearly 800 feet above the Royal Dock in London’s Canary Wharf. The daring stunt came a week before the official debut of the new Jaguar XF at the New York International Auto Show.
