2025 Kia K4: A Bigger, Bolder Forte Replacement and More Features

After two attempts at landing on a successful nameplate for its compact sedan line in the US, Kia is replacing the popular Forte with the 2025 Kia K4. They don’t look like they’re pulling any punches with this thing either Sleek, modern, and now the largest in its class.

2025 Kia K4

Kia has seen a lot of success with the Forte, which replaced the Spectra Way Circa 2010. In its third generation, the Forte offers value-oriented Shoppers a solid alternative to the Toyota Corolla and the Honda Civic.

When it was redesigned for 2021, aligning it with the global name that other markets have been seeing for years

The Forte has been getting known as the K3 in some markets, and the Sado in other markets got a refresh here a couple of years ago, but Kia didn’t change the name to K3.

The K3 name shifted down a size to the Rio position last year, Kia Mexico revealed the all-new K3, and their direct replacement for the Rio there left the Forte position needing a new K4.

Now, if you’re wondering about that Mexican K3, it’s worth pointing out that KIA America did file a trademark for the K3 name not that long ago, so there’s still hope that we might get a Rio replacement here known as the K3 giving Kia a three-pronged approach to the sedan lineup a K3, K4, and K5. There’s no official word on that just yet. Now let’s talk about the vehicle of the hour, and the 2025 K4 uses two carryover powertrains from the old Forte.

However, Kia is not talking about a K4 GT model at launch, instead, the replacement for the Forte GT is the K4 GT line turbo, and you can get the GT line without the turbo, but with the turbo, you do get a new transmission an 8-speed automatic replaces is the old 7-speed dual-clutch. 

Unfortunately, however, the manual transmission option did not cut plus, Kia’s IVT continuously variable transmission with that base 2 L, and we do hope that a K4 GT is in the works, though could Kia fit that 2.5 Turbo from the K5 GT into this larger K4.

The nose of the K4 does differ slightly between the gt-line models and the non-GT line models, and notice on the GT line, there’s more depth to it, and it has a more pronounced tiger nose look, but the regular K4 kind of Strays away from that traditional Kia look but both of them are good looking if you ask me there will be multiple wheel designs available with the maximum at launch being 18 in size, and if you get the 18-in wheels you also get acoustic tires Kia placed a pretty strong emphasis on noise vibration and harshness for the K4 so you will find an optional acoustic glass windshield as well.
