The Audi RS 7 is $120,000 of pure automotive perfection

The Audi RS 7 is unlike anything on the road. It's powerful, sleek, and oddly practical. It doesn't easily fit into a particular category. Is it a supercar? Nope - it has four doors and a ton of storage space, two features that supercars typically lack. Is it a supersedan? Sort of, but it has a hatchback like an old Honda CRX. So it's a fun little hot hatchback? No! It's 16 feet long and costs 120 grand. A four-door coupe? Perhaps.

When Business Insider got the chance to spend a few days behind the wheel of a 2015 Audi RS 7 4.0T quattro Tiptronic, I was on a mission to figure out what this beast was all about.
