Spacious, quick, and quiet, the Avalon is a traditional big sedan updated for modern times. Power comes from a lively 268-hp, 3.5-liter V6 engine that delivers punchy performance and a commendable 24 mpg overall. The four-cylinder hybrid version delivers an outstanding 36 mpg overall. Easy-to-use controls include a straightforward touch-screen infotainment system. Interior noise is subdued. The ride is plush and comfortable, which makes the Avalon an excellent highway cruiser. Advanced safety features, including forward-collision warning and automatic emergency braking, are standard. A redesign, based on the new Toyota Camry, arrives in early summer.
