The Sienna's new 3.5-liter V6 engine delivers where it counts, and it performs beautifully in both city and highway driving. The Sienna pulls quickly from a dead stop and power...
is masterfully managed by an electronically controlled five-speed automatic that makes the most of the engine's torque curve before seamlessly shifting to the next gear.
The Sienna's wide stance and long wheelbase make for an extremely smooth ride and further bolster the Sienna's already rock-solid stability. Some drivers may feel the steering effort to be somewhat heavy for a minivan, but the resultant firm and direct steering makes it possible to pull off highly accurate maneuvers not usually attempted in a vehicle of this sort.
