The 2021 Kia K5 marks the debut of an all-new midsize sedan, replacing the outgoing Optima with a fresh design and enhanced capabilities. Built on an entirely new platform, the K5 introduces a bold fastback-inspired styling that sets it apart in the competitive midsize sedan segment. This model year brings a range of improvements, including a more rigid chassis for improved handling and ride quality, advanced powertrains, and cutting-edge technology features. The flagship GT trim showcases a potent new 2.5-liter turbocharged engine, delivering an impressive 290 horsepower and paired with an advanced eight-speed dual-clutch automatic. Competitors include the Honda Accord, Toyota Camry, Ford Fusion, Hyundai Sonata, Nissan Altima, and Mazda Mazda6.
The 2021 Kia K5 offers two engine options. The standard powerplant is a 1.6-liter turbocharged four-cylinder engine producing 180 horsepower and 195 pound-feet of torque. This engine, found in LX, LXS, GT-Line, and EX trims, provides a good balance of performance and efficiency for daily driving.
The GT trim features a new 2.5-liter turbocharged four-cylinder engine generating 290 horsepower and 311 pound-feet of torque for those seeking more exhilarating performance. This powerful engine transforms the K5 into a genuine sports sedan, capable of 0-60 mph sprints in around 5.8 seconds.
Most K5 models have an eight-speed automatic transmission.
