A carry-over from 2006 when it was completely redesigned, the 2007 Avalon is the flagship of the Toyota line-up, a full-size four-door five-passenger sedan that is offered in XL, XLS, Touring and Limited trim. There is only one engine, the 3.5Liter V6 with variable valve timing that produces 268HP that is linked to an electronically controlled five-speed transmission.
