Kia K5 vs Hyundai Sonata: Turbo, AWD and Hybrid Compared

The Kia K5 and the Hyundai Sonata are two of the last midsize sedans standing, so shoppers who want a roomy sedan often end up comparing them. This guide puts the 2027 Kia K5 next to the Sonata, using what Kia and Hyundai publish, so you know what to look for before you test drive either one. For the full K5 rundown, see our 2027 Kia K5 specs and what’s new page.

The short version

• Choose the K5 if you want a gas-powered sedan with a sporty turbo option and a simple three-trim lineup.
• Look at the Sonata if a hybrid is a must-have. Hyundai offers hybrid trims. The K5 lineup is all gas.
• If you want a turbo sedan with 290 hp, both brands have one. The K5 GT and the Sonata N Line are the trims to drive back to back.
• If you want all-wheel drive, both offer it, but only on one trim each: the K5 GT-Line and the Sonata SEL Sport AWD.

Side by side

The Sonata details below are from Hyundai’s 2026 model year page, and the K5 details are from Kia’s 2027 model year information. A newer Sonata model year may differ, so confirm with Hyundai before you decide.

Powertrains: gas, turbo, or hybrid

This is the biggest difference. The K5 has two gas engines: a 2.5L four-cylinder on the LXS and GT-Line, and a 2.5L turbocharged four-cylinder with 290 hp on the GT. Kia lists a 0 to 60 mph time of 5.4 seconds for the GT.

The Sonata covers more ground. Hyundai lists a 2.5L turbo with up to 290 hp on the N Line, and a hybrid powertrain with 192 combined hp. If you drive long distances every week and want to focus on fuel use, a hybrid is worth a test drive. Check the EPA estimates for the exact trim at fueleconomy.gov.

Driver assistance

Both brands include a long list of standard driver assistance features. Kia says every 2027 K5 has 17 standard collision avoidance and driver assistance features. Hyundai lists forward collision avoidance, lane following assist, safe exit warning, and rear occupant alert on every Sonata, with Highway Driving Assist on the N Line and Limited Hybrid. Feature counts and names do not line up one for one, so ask each dealer for the full list on the trim you are considering. Our team can walk you through the K5’s list in person.

What is new on the K5 for 2027

The 2027 K5 is largely a carryover. The EX trim is gone, leaving LXS, GT-Line, and GT, and the GT-Line can now be equipped with a convenience package that adds ventilated front seats, a driver memory seat, and power-folding outside mirrors.

How to decide

• Drive them back to back. Seat comfort, steering feel, and visibility are things a spec table cannot tell you.
• Pick your priority first. If it is a hybrid, start with the Sonata. If it is a turbo sedan or a simple lineup, start with the K5.
• Match the trim, not just the model. A K5 GT-Line and a Sonata SEL Sport are very different from a K5 GT and a Sonata N Line.
• Think about your drive. Long highway runs, like the trip up the 15 toward Vegas, are where driver assistance features and seat comfort matter most.
