First introduced in 2000, the RS4 has evolved into one of Audi’s most iconic nameplates, despite being available for short periods of time with each generation. First offered between 2000 and 2001, it returned for 2006-2008, and then again for 2012-2015. Each time as a station wagon, but Audi made an exception and offered a sedan between 2006 and 2008. Come 2018 and the Audi RS4 returns for the third time, again in the Avant body styles. But this time around word has it that Audi is also planning to revive the short-lived four-door sedan, which may also return to the United States. While the German firm is mum on the matter, I put together a speculative review with what it may bring to the table.
