I am part of the team who builds the current 3.3 litre 3mz v6 engine for the Sienna van. Currently, minor changes are underway for a new v6 engine for the Sienna as well as the Lexus RX 330. Although model changes won't take place (I believe) until 2006, I would not be suprised to see some minor option changes offered in the meantime. You may want to check with your local dealer. Here are more answers and opinions from other FAQ Farmers: * There are rumors of a hybrid option, but I am sure this will have extremely limited production. * In 2005, all models come with steering wheel audio control.
