The Toyota Sienna has always been an inconspicuous van. They're out there, there's a lot of them and they're huge, but they blend in with darn near everything. Perhaps Toyota noticed that a little while ago and slapped on the slightly garish grille/not a grille plastic thing in the front bumper, but it still doesn't really stand out. On the other hand, our long-term Chrysler Pacifica Hybrid, which is a great deal newer than the Sienna, has slick styling that gets noticed. Toyota hasn't properly redesigned the Sienna since the 2011 model year, and it shows on every front. Despite its many shortcomings, there are still some valid arguments for going with the dinosaur.
The Chrysler is fitted with Nokian Hakkapelitta winter tires. As you might guess, this means that braking and grip around corners is better than the Sienna in snow. If the Sienna were to ditch its slippery all-seasons for a proper set of winters, it would be running circles around the Pacifica. Still, I drove our Pacifica through a lake effect blizzard in Buffalo and it never blinked from lack of traction with multiple inches of snow on the ground. Some folks are going to want the assurance of all-wheel drive, and the Sienna will offer it, but don't make it your only option. All-wheel drive might help you get going, but winter tires are there to save the day when sledding gets tough.
