Image Credit: Graeter's.Toyota has found an unusual way to promote one of the 2026 Sienna's more unexpected features. Instead of another family road-trip commercial, the automaker has teamed up with an ice cream company to create a frozen snack designed specifically to ride along.The result is the Salted Caramel Chip Wheel, an ice cream sandwich that borrows its name from the wheels beneath Toyota's hybrid minivan. A dozen of them will set you back a surprisingly substantial $86 before shipping.According to Graeter's Ice Cream, the limited-edition treats are part of a collaboration with Toyota built around the 2026 Sienna. They're available nationwide exclusively online while supplies last.AdvertisementAdvertisementThere is at least some automotive logic behind the partnership. Toyota wants to show off the Sienna Platinum's available FridgeBox, which can keep food cold or even maintain frozen treats while the family is on the road.$86 Gets You 12 Chip WheelsImage Credit: Graeter's.Graeter's Salted Caramel Chip Wheels are a new take on the company's existing Chip Wheelies. Each one sandwiches salted caramel ice cream between two made-from-scratch double chocolate chip cookies before the outside is rolled in chocolate jimmies.The treats are individually wrapped and weigh four ounces each. They're sold exclusively as a 12-pack for $86, meaning each Chip Wheel works out to a little over $7 before shipping.Graeter's says the limited-edition package is available for nationwide shipping beginning September 1. Once the available supply is gone, however, the collaboration is over.The Sienna Has A Freezer In Its Center ConsoleImage Credit: Graeter's.Pairing a minivan with ice cream makes considerably more sense once you look inside the Sienna Platinum. Toyota offers the range-topping model with an integrated front-console FridgeBox designed to keep food and drinks at the desired temperature.AdvertisementAdvertisementThe system has separate cool and freeze settings. Toyota specifically points to the latter as being capable of keeping items such as popsicles and ice cream frozen, giving the Salted Caramel Chip Wheels somewhere appropriate to live during a road trip.That feature provides the entire premise behind what Toyota and Graeter's are calling "The Sweetest Way to Roll." Instead of simply advertising the FridgeBox, Toyota has effectively commissioned a frozen dessert to demonstrate what owners can put inside it.Toyota marketing general manager Owen Peacock said the feature gives families an unexpected way to bring extra enjoyment to their journeys. Graeter's president and CEO Richard Graeter similarly pointed to the companies' shared emphasis on craftsmanship and products aimed at families.Toyota Has A History Of Having Fun With The SiennaImage Credit: Toyota.This isn't the first time Toyota has taken an unconventional approach to marketing its minivan. The Sienna has previously been at the center of deliberately playful campaigns designed to make family transportation seem considerably less dull.AdvertisementAdvertisementThe FridgeBox collaboration follows the same philosophy, even if $86 worth of ice cream sandwiches is an unusual way to advertise an automotive feature. At least the connection between the two products is easy to understand once the freezer enters the equation.For Sienna Platinum owners, the Chip Wheels also provide a very specific test of whether that FridgeBox can deliver on its name. Everyone else will need to rely on a conventional freezer to protect their roughly $7 ice cream sandwiches from becoming salted caramel soup.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
