You could think of the Kia K5 as the next generation of the Kia Optima. The all-new 2021 Kia K5 builds on the 2020 Optima with enhanced all-weather stability, in-cabin tech innovations, impeccable style, and more. In fact, many Harvey drivers on the hunt for a sporty mid-sized sedan are deciding between the Kia K5, and popular contenders like the Hyundai Sonata.

But which sedan can deliver the upgrades you’re looking for at the right price — Hyundai, Optima, or K5? In the guide below, the team at Ray Brandt Kia compares the 2021 Kia K5 vs. Hyundai Sonata head-to-head to help you decide!

2021 Kia K5 vs. Hyundai Sonata: Dimensions and Design

Before we dive into the Kia vs. Hyundai comparison, we’ll look at a few key differences between last year’s Kia Optima vs. the K5. First, the K5 sports a wider, lower stance than the Optima. Not only does that give it a more athletic appearance, but creates a more engaged and aggressive driving experience — whether you’re hugging curves or making a pit stop for groceries in Marrero.

On the inside, the new K5 offers a sophisticated redesign with more upscale materials like SynTex Seating Material, as well as a quieter ride. Not only that, but the cabin dimensions now provide more room for passengers and cargo. Technology features such as wireless charging and voice recognition have been reworked and improved for the new K5, too.

2021 Kia K5 vs. Hyundai Sonata: Performance

How do Kia vs. Hyundai sedans compare in terms of engine power, torque, and overall driving dynamics? The Kia K5 comes standard with a turbocharged 1.6 liter 4-Cylinder engine and Idle Stop and Go to keep fuel consumption low.

Opt for the GT-Line trim level for stylish features like 18-inch sport alloy wheels, a Gloss Black rear spoiler, and GT-Line front and rear bumpers, plus sporty interior upgrades like GT-Line SynTex seats and a flat-bottom steering wheel. Compare 2021 Kia K5 vs. Hyundai Sonata engines and specs:

2021 Kia K5 Engine Options

  • Base 1.6L turbo 4-cylinder — 180 hp | 195 lb-ft of torque | 8-speed automatic transmission
  • Available 2.5L turbo 4-cylinder — 290 hp | 311 lb-ft of torque | 8-Speed Quick Shift DCT auto transmission

2021 Hyundai Sonata Engine Options

  • Base 2.5L 4-cylinder — 191 hp | 181 lb-ft of torque | 8-speed automatic transmission
  • Available 1.6L turbo 4-cylinder — 180 hp | 190 lb-ft of torque | 8-speed automatic transmission

Looking for next-level performance? Only the K5 offers a true high-performance upgrade. The K5 GT trim level adds Pirelli P-Zero tires and a 290-hp turbo 4-cylinder engine, but you can’t take the Sonata above the base engine’s 191 hp.
