The Toyota Sienna is a family minivan currently manufactured by Toyota at Toyota Motor Manufacturing Indiana in Princeton, Indiana, United States for the North American market.
The 2011 Toyota Sienna with the four gets 19 mpg city/26 mpg highway, which compares to the V6's ratings of 18 mpg city/24 mpg highway. But you'll also be interested to know that the inline-4 is available not just in the cheapskate base model but also the better-equipped LE.That's actually better than the 187-hp 2.7L 4-cylinder Toyota Sienna, which returns an EPA-estimated 19/24 mpg (city/highway).
While we only had two people aboard during our drive of V6- and I-4 models of the Sienna, we noticed the 78-hp deficit of the four-cylinder only while going up a steady grade. As with the V6 model, the I-4's six-speed transmission held gears appropriately, but it was clear that the engine was working harder than the V6. Faced with a choice between the two engines, we'd just drive the V6 more conservatively if we needed better fuel economy. Properly equipped, the six-cylinder models of the Sienna will tow up to 3,500 pounds.
legroom has been lost somewhere in each row of seating from last year to this; it's down 2.4 inches in the front seat, 2.0 inches in the second row and 3.2 inches in the third.
