The 2008 Toyota Avalon is a large sedan from the third generation of the model. It offers a smooth 3.5-liter V6 engine that cranks up 268 horsepower, paired with a 6-speed automatic transmission. It is available in four trims: XL, Touring, XLS and Limited. Standard features include a keyless entry and start system, dual-zone automatic climate control, and a nine-speaker audio system. The Avalon also shines in the safety department, boasting standard full-length curtain-type airbags, front-seat side airbags, a driver-side knee airbag and anti-lock brakes. Toyota's Vehicle Stability Control system, which was optional on previous year models, is standard on all '08 Avalons. For tech enthusiasts, an optional GPS navigation system is available in the higher trims.
