The best line in Toyota's press release announcing the availability of all-wheel drive for the Camry and Avalon: "The company appreciates the loyalty, patience and perseverance of all those customers and dealers who sent letters, emails, comments and texts asking for a modern AWD version of America’s favorite sedan." That's a courtly way of saying, "All you howler monkeys can shut it down. You're welcome." It's been 28 years since the demise of the Camry AllTrac left buyers with front-wheel drive only. The short story is that boffins at Toyota Motor North America Research and Development in Saline, Michigan, married Camry and Avalon uppers with the engine, transmission, transfer case, and rear differential and suspension from the four-cylinder RAV4, and the prop shaft from a Highlander.
