Consumer Reports auto experts report from the 2010 North American Auto Show in Detroit.
Toyota Sienna
What is it? The redesigned Sienna minivan is built on the same platform as the outgoing model which bowed in 2003 as a 2004 model. It uses the same 3.5-liter V6 engine, now upgraded to 265 hp. For the first time, Sienna buyers can also opt for a 187-horsepower, 2.7-liter four-cylinder engine. Both engines are matched with a six-speed automatic transmission in place of the old five-speed. Fuel economy is said to be improved by 1 mpg with the six-cylinder, in spite of a roughly 100-pound weight gain. Front- and all-wheel drive will again be available. And AWD models use run-flat tires again. Overall length is about an inch shorter, but the new Sienna has a slightly wider track.

Inside, three rows of seating for up to eight are standard in all four trim levels. The third row is split, and as before, both halves fold into the floor. Second-row seats adjust fore and aft for increased leg room. A removable center seat for an eighth passenger stows in the rear when not in use. The second-row seats are removable, but oddly, their bases are not. Pricing has not yet been announced but should remain roughly the same.

What is new or notable? This will mark the first time the Sienna has been offered with a four-cylinder engine (Toyotas earlier van, the Previa, offer a four-cylinder engine). Toyota says it will return an EPA-rated 22 mpg overall. Electric power steering is also new, as are available reclining second-row seats with footrests.

CRs take The freshened Sienna looks like a worthy successor to our top-rated minivan, with a spacious, comfortable, and versatile interior. Our engineers and editors had an opportunity to drive a pre-production model at our test track. See our comments in our First Drive .

When will it be available? February 2010.
