2021 KIA K5 GT-Line

The 2021 Kia K5 replaces the Optima as a midsize sedan with a fastback roofline and a sportier stance than its predecessor. It squares off against the Honda Accord, Toyota Camry, and Hyundai Sonata in the fiercely competitive midsize sedan segment. The K5 handles corners with poise and its steering is well-weighted, making it one of the more engaging sedans in its class. Inside, the cabin is roomy and well-built, with a clean dashboard and available 10.25-inch touchscreen that looks sharp. The GT-Line adds 18-inch gloss black wheels, LED fog lights, and a sportier exterior look over the LXS, without the EX's extra luxury features. Its 1.6L I4 makes 180 horsepower and returns 31 mpg combined}, with a smooth-shifting eight-speed automatic that keeps the car relaxed on the highway.
