For 2007, the Sienna has more power than ever, with a larger, more powerful 3.5-liter V6 under its hood. The new engine gives the Sienna class-leading power, without a significant reduction in EPA mileage ratings. We found the 2007 Sienna offers impressive acceleration and just seems to have more driving excitement about it than last year's model.

The Sienna is big and roomy, but it doesn't drive bulky and it's not hard to park. It's smooth, responsive and quiet, and compared to sport-utility vehicles with comparable functional capability, it's more fuel efficient. It will switch from eight-passenger mini-bus to cargo hauler in minutes, with room for full sheets of plywood, 10-foot ladders and significantly more cargo space than most full-size SUVs. It will tow a family camper or small watercraft, and it doesn't look odd in the line for valet parking.
