2021 marked the launch of the all-new Kia K5, which replaces the Optima in the Kia lineup. This sleek, sharp midsize sedan presents a formidable option for Harvey drivers looking to add sophistication and sportiness to their daily commutes and weekend cruises. Curious to learn what the 2021 Kia Optima K5 switch means for you as a car-buyer? Read on below as we cover the main differences between the Kia K5 vs. Optima. 


Kia K5 and Optima: Performance Comparison

The all-new Kia K5 comes with a standard 180-hp, 178 lb-ft of torque 2.4L inline 4-cylinder engine under the hood. This is a nominal difference from the base engine on the 2020 Optima: a 2.4L inline 4-cylinder that produces 185 hp and 178 lb-ft of torque. The trade-off here is the incremental gain in gas mileage, with an EPA-estimated 29 mpg city / 38 mpg highway / 32 mpg combined on the K5 vs 25 mpg city / 35 mpg highway / 29 mpg combined offered by the 2020 Optima. 

As far as upgraded engines, you’ll get more power driving around Marrero in the K5. Here’s how the most powerful engine options on both models size up: 

K5 Turbocharged 2.5L 4-Cylinder

  • 290 hp

  • 10.0:1 compression ratio
