Built on the same platform as its predecessor and riding on the same 119.3-inch wheelbase, the new Sienna is marginally wider but nearly an inch shorter overall. Exterior styling is all-new and far less anonymous than before; we might even go so far as to call it attractive. The shape is especially slippery, too; Toyota claims a low 0.31coefficient of drag. The newfound style continues inside, where sweeping lines look more interesting and modern than the upright and conservative design of the previous Sienna. Interior plastics are pleasing to the eye, but touching them reveals a hard and slightly cheap-feeling texture.
