It may come as a surprise but small sedans come in different sizes. In this case, the 2025 Kia K4 is much bigger than the Toyota Corolla in Phoenix. You only have to look at the passenger volume to see that. At 98.7 cubes, these Kias are 10 cubes bigger than the Corolla sedan at 88.6 cubes.

This allows the K4 passenger to enjoy an extra four inches of rear legroom. A bigger backseat is always helpful, even if it’s just used for children. Bigger is better when installing carseats.  

Corolla sedan trunks are rather small at 13.1 cubes. At 14.6 cubes, K4 trunks are nearly as large as any midsize sedan. Bigger is better when taking a long trip.  

Since the new Kia sedan was designed from the wheels up, the designers were able to give it a definite style that has caught the attention of critics. In its recent review of the best looking cars, US News and World Report includes the 2025 Kia K4. Even with its low price tag, it’s made it onto this prestigious list that includes luxury cars such as Porsche, Audi and the Chevy Corvette.  

K4 vs Corolla Performance

The 2025 Kia K4 offers two fuel efficient powertrains. The 147-horsepower engine can be upgraded to 190 horsepower and 195 lb-ft of torque. Corollas have a 169-horsepower engine with 151 lb-ft of torque.

Fuel efficiency is similar with the K4 earning as much as 33 mpg in the city and 43 mpg on the highway. Toyota efficiency numbers show 32 mpg city and 41 mpg highway.  

Driver Cockpit Technologies

If you want the latest infotainment technology, you’ll definitely lean toward the K4 with its 12.3-inch touchscreen. This standard display is four inches bigger than the standard Toyota screen. This is still almost two inches bigger than the Corolla’s larger 10.5-inch screen.

 While Toyota holds back its smart key for a higher trim, Kia provides it on the most affordable K4. This device includes an exclusive remote starter to help you cool the car on a hot summer day in Phoenix.

Both models come with a long list of safety devices, including pedestrian detection and forward collision autobrake. However, Kia doesn’t hold back. It includes a blind spot monitor and the related rear traffic alert in addition to its lane keeping assistance.  

Ownership Costs

With its bigger touchscreen and longer list of standard features, only the K4 can claim excellent value with a competitive starting price. The 2025 Kia K4 price starts at a low $21,990 while the Toyota Corolla price is a bit more at $22,325.

When it comes to fuel efficiency, the two models are so close that you can be sure that either one will save you a great deal at the pump. With the K4 earning 40 or even 43 mpg on the highway, you don’t need a hybrid.  

Furthermore, Kia offers up to two extra years on the basic warranty and five extra years on the powertrain warranty. It even offers three additional years of complimentary roadside assistance. This industry-leading warranty should provide superior peace of mind to the K4 owner.  

All in all, the Kia K4 pulls ahead of the Corolla when it comes to current and future ownership expenses. For those looking for affordability, this should seal the deal for the K4 vs Corolla in Phoenix.  

Conclusion

While the Corolla is better known, the K4 counters with a longer warranty, more features, and a more engaging driving experience. Plus this Kia is much bigger than its rival and can handle more luggage, too.
