While sports cars provide a lot of fun, they come with a major downside: practicality is crap. But here’s where high-performance sedans come in. While four-doors weren’t very dynamic a few decades ago, they can be as agile as an entry-level sports car nowadays. And in addition to the power and speed, they can also provide seating for four or five people and decent trunk space. But hey, it gets even better with wagons, which can provide a lot more storage room, sometimes enough to go on a long vacation with the wife and the kiddos. Why am I talking about high-performance grocery getters, you ask? Well, the super awesome Audi RS4 Avant was just unveiled at the 2017 Frankfurt Motor Show.
