Another interesting option for the new Sienna is dynamic cruise control, where the driver can set the speed and keep a continuous distance from the vehicle ahead. The Sienna systems can brake and accelerate without input from the driver. Also a nice addition, both backup and front low-speed parking sensors inform the driver of potential bumper-damaging objects at each corner.

Other class-leading additions include the largest disc brake option available, a headliner airbag covering all three rows, powerful navigation and entertainment electronics, more seating versatility than most living rooms, and storage compartments hidden all around the interior.

Toyota will offer four model lines (CE, LE, XLE, and Limited), with the majority of sales projected to be the mid-level LE, tentatively priced just below $25,000. Base prices will start around $23,000, with fully loaded Siennas running above the $35,000 mark. With maximum production numbers at 150,000 for the current Princeton, Indiana, plant, Toyota may need more than just a home run from the Sienna with more expansion planned that could support another 50,000 units per year.

As it stands for the new Nissan Quest, due at the end of this year, and the next Honda Odyssey not long after that, this could be the most competitive segment around for many years to come. Sounds like good news for minivan shoppers.
