In search of an exceptional mid-size sedan for your daily commutes and weekly errands? The 2023 Kia K5 and Hyundai Sonata are both strong contenders deserving your consideration, particularly when equipped with their 1.6L turbo I-4 engines, which offer similar performance.

However, where the Kia vs. Hyundai showdown heats up is in their interior design and amenities differences. Your final choice between the two will likely be influenced by your preferences for the cabin. Dive deeper into our Kia K5 vs. Hyundai Sonata comparison below.

K5 vs. Sonata: Interior Design & Amenities

The Kia K5 introduces a fresh take on interior luxury, while the Sonata cabin aims to convey a sense of speed. Hyundai has sought to break away from its standard brand offerings, whereas the Kia K5 has embraced its roots with more traditional touches favored by many Gastonia drivers. The Kia K5 seamlessly blends modern minimalism with classic elements and premium materials.

Here are a few Kia K5 interior highlights to watch for that distinguish it from the Hyundai Sonata:

  • Analog gauges
  • Traditional shifter
  • Leatherette map pockets
  • Brushed-nickel and matte-finish faux wood trim materials
  • Light gray leatherette seating

Kia K5 vs. Hyundai Sonata: Interior Dimensions

Interior dimensions offer another significant point of comparison for smaller vehicles like sedans. So which model offers a more comfortable ride? The Kia K5’s cabin provides extra room in ways that can make a difference during longer journeys from Kings Mountain or Gaffney, SC when heading to your weekend getaways.

Let’s delve into the interior dimensions of these Kia vs. Hyundai vehicles include:

  • Hip Room: The K5’s front-row bucket seats measure 56.6 inches across, a full two inches wider than the Sonata front seats.
  • Second Row: Rear passengers can get more comfortable in the K5, with an extra inch-plus of headroom and legroom.
  • Passenger Volume: In terms of volume, these small differences add up to an extra cubic foot (and then some) of total passenger volume for the K5.

Kia K5 vs. Hyundai Sonata: Performance

Both these fine sedans are equipped with a 1.6L turbocharged I-4 engine paired with an eight-speed automatic transmission, ensuring nearly identical acceleration and performance on Forest City-area highways.
