Driving Dreams is about China's new love affair with the car – how it promises freedom to travel and a better life – and how the world's automakers see it as a market as large as the rest of the worlds' combined. Driving Dreams is also about the environment and what's at stake as cars – to some degree everywhere but especially in China, pollute the skies. Part One: Jaguar has a new model, the XK. It's being presented at the London Auto Show and, for Jaguar's chief stylist Ian Callum, it's important that this beautiful, fast car stand out. Jaguar is resting its future on it.
