Introduce your family to ours. The All New 2012 Sienna is unique to every family. That's why Toyota offers so many different versions of Sienna. All told , there are five models to choose from, LE, SE, XLE, and limited. There's also a choice of engines: either a thrifty 4-cylinder, standard on the Sienna and LE grades, or for more power, the available V6. And for an added measure of confidence, you can go with available All-Wheel Drive (AWD).
