Ahead of its official North American debut at the Pebble Beach Concours d'Elegance, Jaguar gave us a look at the new XJ in San Francisco.The new XJ was designed by Ian Callum and is a radical change from the previous body style, which was little changed for 40 years. The newcar's look might tweak Jaguar purists, but the lines are modern. In some respects, it resembles the XF. The XJ will be Jaguar's flagship sedan, and the first launch under new owners Tata Motors. The new XJ features some impressive tech,its most over-the-top feature being a virtual instrument cluster.
