Overview & Reviews
The 2007 Toyota Sienna benefits from a major power upgrade, as a new 266-horsepower 3.5-liter V6 replaces last year's 3.3-liter engine. This makes the Sienna the most powerful minivan on the market. In other news, all '07 Siennas with CD changers are satellite radio-ready (Sirius), and the standard tire-pressure monitoring system now has sensors for each tire (resulting in more accurate readings). The available 17-inch alloy wheels have a new finish.
- Powerful and refined V6, smooth ride, packed with convenience features, choice of seven- or eight-passenger seating, available all-wheel drive, tight build quality.
- Expensive option packages, uninspired handling, noise isolation could be better.
