Why it stands out

The 2021 Kia K5 shines as a noteworthy sedan in the current market by successfully blending style and performance. As a successor to the Kia Optima, the K5 brings a more aggressive design language with a captivating fastback silhouette that rivals even higher-end models, making it a standout for buyers looking for a visually appealing vehicle. Its 1.6-liter turbo engine, producing 180 horsepower, ensures a peppy yet smooth driving experience, while the eight-speed automatic transmission provides efficient transitions. Despite some drivers noting that it may not drive as sportily as its looks suggest, the K5's impressive fuel economy—rated at 27 mpg city and 37 mpg highway—offers great value for any commuting needs.
