The Sienna houses a new 296-horsepower, 3.5-litre V6 with direct injection. Power is sent to the front wheels—and the back wheels in the category-exclusive all-wheel drive version—via a new eight speed automatic gearbox. The SE trim, with firmer steering and suspension, is also unique in this category. Although the Sienna is looking its age, its cabin remains roomy and comfortable. There's even an intercom to communicate with the passengers sitting in back.
