I Thought That Nothing Could Rival the Honda Civic Sedan at Its Price Point, But Then I Tested the New 2025 Kia K4 GT-Line, and Have Discovered a Great New Option For Buyers To Consider

Kia’s new K4 GT-Line sedan offers much of what the Civic Sport does, plus one important advantage over the Civic. Here are our takeaways after a week of testing. 

I’m not going to sugarcoat this. Having tested the 2025 Honda Civic, I feel that it is almost unbeatable. Particularly the hatchback versions. So, when Kia sent us a new K4 to test, that clouded our judgment a bit. How could Kia possibly match or top that new Civic? Well, they have, and depending on your priorities, the K4 may even be a better option. In this unconventional review, we’ll focus on the things that differentiate these two great vehicles.

The great news for shoppers in the sub-$30K car market is that great looks are free. Both the Civic and K4 are handsome cars outside. We particularly like the coupe-style rear doors on the K4. Kia's now signature C-pillar is also a styling element we feel sets the K4 apart.

Our sub-$30K K4 GT-Line tester had a two-tone interior that knocked our socks off. The steering wheel’s flat top and bottom was also novel, and we loved it. 

Kia K4 vs. Honda Civic - Powertrains
We tested the K4 GT-Line. Its 2.0-liter engine and variable automatic transmission were adequate for the role, and that is what you now get with the Civic. In our driving on mixed suburban and urban roadways, including some pretty heavy traffic, we observed 42 MPG in the K4. With that kind of mileage, we’d likely skip getting a hybrid.

For 2025, Kia offers the K4 with a trunk, and it has four doors in a sedan layout (with coupe styling). Honda offers a sedan or a hatchback. However, in 2026, Kia will introduce its K4 hatchback. Personally, I favor the convenience and added cargo volume that a hatchback offers. That is just one person’s opinion. The great news is that both brands will be offering both options, so buyers can pick and choose. 

Kia K4 vs. Honda Civic Pricing
We’ve reviewed prices and see that both of these models offer a tremendous value. You get a LOT for not much money. Our K4 GT-Line tester had a consumer cost of $28,345, including Kia’s inland freight and handling fee, but less whatever Doc fees your Kia dealer charges. Honda’s Sport with similar content has a price of $27,831.

We love that Kia offers a spare tire in the K4. Honda offers a spare on only certain trims. We also loved how easily we could connect to the wireless Android Auto in the K4 - even without using a power cable to initiate the pairing. Here, Kia is the match of Honda, which also offers an outstanding infotainment package. 

Here's a listing of all the top-selling cars with spare tires. 

Kia K4 - The Drive
We found the K4 to have a great personality. We’d call it “chill” or “mellow.” The K4 GT-Line with its 147 hp engine was just adequate, and never felt sporty. If you want more power, there is a GT-Line Turbo with 191 hp available, but it comes at a meaningfully higher price tag. We’d probably skip the turbo in this car, and live with the base power rating. The handling is nice. It’s always enjoyable to try a low-slung sedan after being in crossovers most of the time.

If performance is a priority for you in this vehicle segment, see if you can stretch the budget to the Mazda3 Turbo. It starts at $34K. 

Kia K4 GT-Line Conclusion
If you are shopping for a sub-$30K vehicle, it’s hard to overlook the Kia K4 GT-Line. It offers a great look, stylish interior, plenty of space for four or even five passengers, and many features we think make it a great value. One thing we really like about the Kia line is its 100,000-mile warranty for initial owners. This is one area where Kia objectively beats Honda. If we were shopping for a sedan under $30K, we’d check out the Kia K4 before deciding on any of the other choices in the marketplace.

I bought the Kia K4 EX -- the middle choice that has more options than the 2 below and a few options less than the 2 above. The cloth seats are incredible! The faux-leather steering wheel wrap is great! And, of course the dash design. Another couple thousand off the GT-line! This is the best value.

Comparing a Honda to a Kia, is like comparing a piece of gold to a turd!! I wouldn't own a Kia, I wouldn't want to be ya, in a Kia !! I have a 2003 Honda Accord with close to 200k on it!! I think it will go another 100k, if the rust doesn't get it first!! Good luck with the Kia!!🤣🤣🤣

I dont know that is true today. Your Old accord went the distance however mine breaking down after 100k km. Personally I over maintained it. Did oil changes at 5-6k kms and cvt oil change at 50k (including 2 filters). Now It has all the codes in the dash and honda wants 2-3 k to repair it.

John, I like this direct "most likely" comparison. Two notes: 1. Since you bolded the mixed driving fuel economy, maybe insert the mixed driving MPG result with the Civic (I clicked your link and it was the Si, so not apples-to-apples); 2. More importantly, everyone agrees the Civic is really good except for one (in my old man case) fatal flaw--noise at speed. At 65 or 70 mph, is the Kia any quieter? The thing that makes my '18MY Fusion Hybrid Titanium still feel very much premium is the wind/road noise isolation, both under full throttle and cruising. Ford absolutely killed it in making the Fusion feel premium, especially in Titanium/Platinum versions, with it's upscale interior and luxury-levels of quiet. Cheers, CT

How reliable are Kias that they have to come with a 100k warranty? I've heard many Kias are usually in the shop for warranty work. I just take my Honda in for required maintenence (eg. Oil change, tire rotations, trans flush, brake fluid flush...).

Nunya (not verified)    April 29, 2025 - 11:23AM

Yeah I'm sure this car is great if you like exploding engines within 100,000 miles. Stick with toyota or honda if you keep cars longer than 5 years

Walter (not verified)    April 29, 2025 - 11:50AM

All true; but. I also made varying choices not Honda including a Kia but kept on looking at my wife's 12 year old Accord. Honda repair records are minimal.

Michael (not verified)    April 29, 2025 - 12:37PM

I’m sorry, but with Kia/Hyundai‘s reputation for engine issues there’s no way I’d consider this car. Not to mention the new styling language from Kia is unattractive, to say the least.

Andrew O'Neill (not verified)    April 29, 2025 - 1:39PM

I'm sorry, but that's just ugly. That and the thing about Honda's is that they retain their value because of the quality of build and well known reliability. The Kia has a 100k warranty for a reason, and it's not because it competes with Honda in that regard.

Stephenz (not verified)    April 29, 2025 - 1:45PM

😂😂 yeah, tell me about it 5 years or 160k from, and try to sell both. Then your comparison will be worth looking into.
My accord has 220k, my 2010 Fit 230k, my 2007 Ridgeline which I sold for $5,500. Had 179k with quite some rusts.

Mark Pearcey (not verified)    April 29, 2025 - 2:00PM

Not any kind of car expert at all but if everything is fairly equal, I would go with the Honda over the Kia based on long term history of very reliable vehicles. I am also the owner of 2 honda vehicles, one being an Odyssey with over 233,000 miles, so I may be biased

David Shull (not verified)    April 29, 2025 - 3:49PM

I would not wanna be behind one on the highway on a hill like I-70 in Colorado. Would it One of those things all show an no go. Sounds like the turbo actually doesn't have much power either.

Which hill? Eastbound or westbound? Doesn't matter. Our fleet is almost all Hyundai or Kia, and we go border to border in the state, and we have vehicles operating with 300K miles. Of course, our fleet management are obsessed with punctual and thorough preventive maintenance. Our Western Slope fleet hits I 70 on a daily basis, and have no issues hitting those hills at speed. The last time I drove the route Eastbound from Idaho Springs to Golden in a Sonata was a cake walk, just hit the gas and go.

Kia, like their parent Hyundai, are unreliable. They both use the same California design studio so their vehicles look attractive but the quality is absent. Kia uses many cheap Chinese parts to cut costs. Reliablity suffers as a result.

Japanese made Honda cars also include cheap Chinese parts which break down regularly. American made Honda vehicles are reliable, not as good as Ford or GM, but far better than Kia.

Jon Burnes (not verified)    April 29, 2025 - 9:11PM

If your planning on driving the car for many miles, the Honda has significantly better electronics durability and superior wheel bearings and brakes. The Kia and Hyundai's are fine cars...just not as high a quality in some of the unseen parts.

Phil (not verified)    April 29, 2025 - 9:34PM

But you have to factor in that Kia manufacturing, overall quality, and longevity, are complete rubbish! They're build tolerances and inspection processes are horrible.

Jason B (not verified)    April 30, 2025 - 12:08AM

Test them again in 101k miles when the Kia drops its third engine. This time out of warranty. Then compare resale values in a few years. There is a reason they have to offer a 100k warranty and it's not a selling point unless you're an idiot. This article reminds me of when the garbage writers in the 90s compared the Dodge Neon with the Civic just to have something to babble about. Getting people to screw themselves over because they think that they are listening to an expert is just not cool.

Sure, KIA is known for bad engines, just do a google search. Got rid of the kids Sorento at 62k miles knowing that 2.4 was going bad. Honda has had issues but the Accord is worth every penny it costs. I have three Honda and will not buy another Korean Car.

This is just my experience and opinion. I drove a 2010 Kia Forte, which now is called K4, for 11 years. I don’t drive much so my Km was around 100Km. I never had any issues with that car. Only did regular service, oil change etc. I traded it in for a Nissan and hated it. Last November I bought the 2025 Kia K4. It been 6 months with no issues. My tires had nails because of all the construction work going on in BC.
It drives great. Mileage is excellent. Like I said I don’t drive much so my Km has just hit 1000. Seating is comfortable, which is important for my back. If you’re not too concerned about what brands you drive and just need a reliable car which will last you years then K4 is a great choice. I’ve driven Kia’s for the last 20+ years and enjoy the way they drive.

I'm a Kia person. 2012 Kia Forte Koup, with a 6-speed manual transmission, that I still own and drive every day. I leased a Kia Sorento in 2017, then a Kia K-5, and now have a 2023 Forte GT line. Great cars. Lots of extras are included in the price. my 2023 easily gets 43+ mpg on the highway.

Mark Cihlar (not verified)    April 30, 2025 - 4:33PM

Price is good,but shouldn't out weigh quality and long terms reliability. Kia are good under 60k mileage,honda great over 60k and beyond. Bottom line Honda all the way or toyota.
