Lauren Conrad is a TV star from the MTV shows “Laguna Beach” and “The Hills.” While you can easily say her roles lack, well, substance, you cannot say the same for Conrad’s ride. It is full of it, in a good way. She rides around Los Angeles in the incredible Audi R8 supercar. The midmounted monster — which goes zero to 60 mph in 4.6 seconds, delivers 317 lb-ft of torque and has a top speed of 187 mph — is also favored by macho types such as English soccer ace Robbie Fowler and actor David Hasselhoff. So, while seeing a tiny, blond, SoCal reality TV star tooling around in this powerhouse is a bit disconcerting, it’s also, dare we say it, totally awesome! It sure beats Paris Hilton’s cringe-inducing pink Bentley.
