Jaguar's design chief, Ian Callum, takes the wraps off of the first 100 percent Callum car. Some see it as too great a departure from "Jaguarness." Others, like me (I worked at Jaguar years ago), see a muscular yet curvaceous shape that is every bit a Jag.

The pressure is on: As the only all-new Jag model on the product horizon, the sedan must sell well when it comes to market next year--the struggling Ford-owned British marque has been in a multi-year slump.
