Despite being in its 6th year of existence, the Toyota Sienna is in a status quo. If we can trust the “spy” photos that are floating around on the Internet, we can say that the 3rd generation will be ready for 2010. Until then, the minivan is still one of the most spacious in its class, and is still the only one to offer all-wheel drive. Its fuel-consumption is leaner than the Odyssey’s, even though, unlike its Honda rival, it doesn’t offer cylinder deactivation.
