Everything but the Kitchen Sink

Toyota has no illusions about what this all-new next-generation minivan must be: "Simply put, this has to be a home run," says John Jula, executive engineer/program manager for the Toyota Sienna. "And we think we've done more than that."

The all-new Sienna, built from the new Camry platform, is longer, wider, faster, and loaded with many (if not all) of the best features offered by the competitors. "This segment is about kids, so we've tried to give them everything they (and their parents) might need," Jula says.

The Sienna's engine is the same transverse-mounted 3.3-liter V-6 and five-speed automatic transmission recently introduced in the new Lexus RX 330. In fact, many of the Sienna's interior details remind us of the Lexus compact SUV, and, of course, that's no accident. Gone is the column shifter, replaced by the familiar dash-mounted lever from the RX 330 and Toyota Highlander, allowing for more dash visibility and an overall sportier feel (although, maybe that's not so important for a minivan).

In addition to being longer, wider, and taller than the previous model, where other manufacturers said it couldn't be done, Toyota found a way to accommodate an all-wheel-drive system (an option) with an easy-to-use fold-away full-size third-row seat. Toyota has done away with the underside-stored spare tire by equipping all-wheel-drive models with runflat tires. Among the upgrades, the third-row seat is one of the most impressive pieces of technology we've seen in a while. Equipped with spring-loaded struts, the two-step pull-and-flip system is the easiest, most convenient way to use and store additional seating we've seen. Other comforts include electronic, driver and passenger sliding rear doors, as well as a hands-free rear hatch (complete with annoying warning beeps). The new Sienna offers roll-down windows in the electric sliding passenger doors, too. Only two vehicles in the category have that option.
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.
