If you’ve heard people talking about the 2021 Kia K5 and wondered what to expect from the new model, you’re not alone. Longwood drivers who were looking for a 2021 Kia Optima will find it in the 2021 Kia K5. The latest evolution of Kia’s mid-size sedan, the K5 is essentially the next generation of the Optima. What’s the difference between a 2020 Kia Optima and 2021 Kia K5? Quite a bit, actually. See what the future of Kia’s mid-size sedan looks like below.

Kia K5 vs. Kia Optima: Design & Dimensions

The first place where the K5 varies from the previous Optima is in its design. The 2021 K5 is wider, lower, and longer than the 2020 Optima, delivering a more aggressive look and feel as you drive around town. The result is a car that gives you more room, whether you’re doing your daily driving around Sanford or taking the family on a trip.

When compared to the outgoing Optima, the Kia K5 has a more sophisticated, upscale interior. Not only is the cabin more spacious, it’s been engineered for a more quiet ride, and tech features like voice recognition and wireless charging have been improved over previous models.

Kia K5 vs. Kia Optima: Performance

One of the biggest ways the K5 differs from the Optima is the drivetrain. While front-wheel drive is standard on both models, the 2021 Kia K5 can be had with all-wheel drive. If you’re seeking a mid-size sedan that’s got a bit more grip on the pavement and feels exciting to drive around Winter Springs or Deltona, the Kia K5 doesn’t stop with AWD — it offers a more powerful engine as well:

  • The 2020 Kia Optima is available with a 245-hp 2.0L turbo with 260 lb-ft of torque.
  • The 2021 Kia K5 can be driven home with a 290-hp 2.5L turbo with 311 lb-ft of torque.

In practical terms, the K5 GT is expected to go from 0-60 mph in 5.8 seconds — a full second faster than the comparable 2020 Optima.
