No. The Kia K4 is not an EV. Most trims are powered by a 2.0-liter gasoline four-cylinder engine, with a 1.6-liter turbocharged gasoline engine on the GT-Line Turbo. Kia has three electric cars, EV3, EV6, EV9 and Niro EV, available as stand alone models.
What gas does the Kia K4 take?
The 2026 Kia K4 is fueled by regular unleaded gasoline. Regular fuel is used for all trim levels, including the GT-Line Turbo.
What's the difference between the Kia K4 and K5?
The K4 is a compact sedan, and the K5 is a midsize sedan. On the whole, the K5 offers more passenger and trunk room, as well as a more potent turbocharged engine option (up to 290 horsepower on the GT trim). The K4 likes fuel efficiency and a lower starting price, reaching 33 MPG combined vs. up to 30 MPG on the K5. The K4 is also offered in a hatchback body style, which the K5 is not.
Is the Kia K4 electric or gas?

Neither version is a hybrid or plug-in hybrid. For Kia's electrified compact options, the Niro Hybrid, Niro Plug-In Hybrid, and Niro EV occupy that space in the lineup.
