Generally, when we talk hybrids, we're talking about a car that either powers itself on batteries at low speeds, only firing up the internal combustion engine when a little extra giddy-up is needed, or an electric car that turns the gas-powered piston pusher inside into a glorified power plant.

The e-tron quattro also has a sibling, the Audi R18 Ultra, which seeks to compensate for the added weight of a hybrid drive train by using extremely lightweight materials, like carbon fiber, wherever possible -- including the gearbox.
