Lamborghini launched a website called the Hexagon Project. It asks that you submit your email address and then gives you a taste of a glorious V10 engine noise. The message: "Listen to your instinct. Discover the roar of a new creature from Lamborghini. That will be just the beginning."

But which Lambo is it? The popular opinion from Jalopnik, is that this is the engine for Lambo's Gallardo replacement, rumored to be called the Cabrera.
