After being on sale since the 2015 model year, the Kia Sedona is finally being replaced by an all-new model. Sales of Kia's minivan have been lagging behind its established rivals such as the Chrysler Pacifica, Dodge Grand Caravan, and Honda Odyssey but its replacement will have some big changes to help Kia catch up with the competition. A recent report claimed the 2021 Kia Sedona will debut at the 2020 New York Auto Show in April before the Korean version is unveiled in July, where it's known as the Kia Carnival.

Kia hasn't released any official teaser images yet, but new spy shots released by Club Carnival and Korean Car Blog give us a first look inside its fancy new interior completely undisguised - and it's a lot more luxurious than we expected.

Compared to the current model, the new 2021 Kia Sedona will feature a large widescreen incorporating the digital gauge cluster and infotainment system similar to the widescreen setups inside Mercedes-Benz models, as well as more luxurious materials.

In the current Sedona, the base model includes a seven-inch touchscreen display with Android Auto and Apple CarPlay integration, while the more premium LX trim has an eight-inch touchscreen display. The design of the steering wheel, infotainment system, and touchscreen appears to have been lifted from the upcoming new Sorento, but the design of the air vents is unique.

As for the exterior, the new Sedona will have a more boxy design, while the front fascia will feature cues inspired by the Kia Soul including new LED headlights with integrated LED daytime running lights, and a redesigned bumper. In terms of dimensions, the new 2021 Kia Sedona will reportedly be 1.5 inches longer and 0.3 inches wider than the current model, measuring 202 inches long, 78 inches wide, and 68 inches high. The wheelbase will also be extended by 1.18 inches at 121.6 inches, providing rear passengers with more legroom.

Under the hood, the Sedona's current 3.3-liter V6 is expected to be replaced with Kia's new 2.5-liter turbo. It may also be available with the same hybrid powertrain as new Kia Sorento and Hyundai Santa Fefacelift, which uses a 1.6-liter turbo GDi and an electric motor.
