The next-generation of Toyota's premier sedan is scheduled to appear in 2005. The Camry's older, more genteel sibling will feature an updated profile based on a Camry platform. Expected to be larger and longer than its predecessor, the new Avalon will also feature a more spacious interior. Powertrain will be a 3.5-liter V-6, which is basically a beefed-up version of the Camry's current engine. This V-6, which will probably be mated to a five-speed automatic, should be capable of at least 270-horsepower.
