The Toyota Sienna rides as good as or better than any comparable model. Toyota Sienna's 3.0-liter V6 engine, four-speed electronic transmission, steering system, gearbox, and front suspension are standouts for refinement.A big, tall box will never ride and handle as well as a low, sleek sedan, but the Sienna is pretty good. The steering isn't as sharp, and the transient response isn't as crisp as some of the other minivans; it leans in the corners, and seems a bit mushy in transient maneuvers. But overall, the Sienna handles well and its soft suspension makes up for any handling deficiencies with its smooth ride quality and solid stability at high speeds.
Toyota's V6 is easy to live with. It's smooth, reliable, and economical. Power isn't an issue. It generates 210 horsepower, slightly more than the Ford Windstar's 3.8-liter V6 and on par with the Chrysler Voyager's 3.3-liter V6. Passing other vehicles on hills is easy: Punch it and the Sienna takes off, quickly putting slower vehicles away. Toyota recommends premium fuel. Toyota's engine is efficient with EPA fuel economy ratings of 19/24 mpg city/highway.
