My Honest Review of the 2021 Kia K5

Over the weekend, I had the opportunity to rent a 2021 Kia K5 LXS (second trim level) from Enterprise in San Francisco. I drove it for about 250 miles, combining highway and local routes, including a 20-mile stretch through winding roads on my way to a state park.

Here’s the TL;DR – For the price, it’s a solid performer. The 1.6T engine has good power, and if you keep the turbo engaged, it’s actually quite fun to drive. The tech package is pretty solid, though the interior features a lot of hard plastics.

I won’t dive too much into the exterior design since it seems to be a love-it-or-hate-it situation. Personally, I think it looks fine for the price range. It’s modern without being over the top.

The interior layout is something I really liked. The way the screen is integrated into the dash looks much more polished compared to the “tablet on a stick” style you see in some Mazdas and Toyotas. I’m also happy to see that Kia kept physical buttons for all the major functions, though I found the oversized audio buttons to look a bit cheap. The piano black plastic around the controls also gives off a low-end vibe that might not age well. HVAC controls are separate, and I was pleasantly surprised to see automatic climate control in this second-tier trim. However, the manual fan control only has low, medium, and high settings, which is less precise than what you get in most other cars. The seating was simple but comfortable, though the cabin had more hard plastics than I’m used to in my Subaru Outback. I also didn’t like that the armrest doesn’t move forward. And that odd “T” shaped shift knob? Definitely feels like a relic from 15 years ago.

On the tech front, Kia made some puzzling decisions. The trim includes Android Auto/CarPlay (which worked flawlessly with my Pixel 3a, both wired and wirelessly), radar-based blind-spot detection, emergency braking, and lane-keeping assist, but no adaptive cruise control. That’s an extra $1,600 on the GT-Line trim, and even on the highest trims (EX and GT), it’s part of a $3,400–$4,000 “Premium” package. To me, this doesn’t make much sense. I’d rather have adaptive cruise control as standard and save the advanced safety features for the premium packages.

Performance-wise, I was impressed. The 1.6T engine has plenty of power—more than my 2.5L Outback. I had a lot of fun launching from stoplights and downshifting to pass on the highway. Below 2,500 RPM, though, it feels sluggish. But if you keep the turbo spinning, the car is responsive and fun to drive. The 8-speed automatic transmission is smooth, much better than other automatics I’ve driven, with no jerky shifts. The car behaves almost like a CVT with fake shift points (similar to my Subaru). The shift times aren’t lightning fast, but for a family sedan, that’s not a dealbreaker. The stock tires, however, leave something to be desired. I had no trouble getting them to squeal on dry pavement, even with traction control engaged. The handling is good for a car this size—while not as agile as my Miata, it held its line well, even when I pushed it 10 mph over the speed limit on some curvy roads.

In terms of noise, the K5 is surprisingly quiet. At highway speeds of 75–80 mph, the cabin noise was much lower than expected, and the engine noise was minimal, even at higher RPMs, making for a comfortable driving experience.

Would I buy this car if I were in the market? That’s a tough question. With adaptive cruise control locked behind a premium package, the price would be around $27k, which puts it in the same price range as the Hyundai Sonata (which also limits ACC to higher trims). However, to get the turbo in the Sonata, you’re looking at a more expensive SEL Plus model at over $28k. The Toyota Camry is a no-go for me, as I find it unattractive inside and out, though it does offer ACC as standard. The Honda Accord has a nice 1.5T engine and a good look, but it comes with a CVT. The Subaru Legacy has a large LCD screen but lacks power with its 2.5L NA engine and also uses a CVT. I’d say the K5 is a solid contender. With better tires and the GT-Line package for a more premium interior, I could definitely see myself enjoying this car.

I agree with you. I had a 2013 Elantra GT6 manual and in my opinion it was just as good, if not better, than the Civic from that year. Especially with Honda moving to CVTs, I think Kia and Hyundai are more fun options for those wanting a sedan with an automatic.

Are you talking about Honda’s interiors in terms of how they feel and look?

Because to me, their interiors seem pretty cheap overall. I’ve sat in their full range and nothing really impressed me.

@Bailey
I’ll admit they aren’t great compared to others in the same group. Mazda has really stepped up their interior game, but I haven’t been in many Toyotas to compare. Kia and Hyundai interiors look very nice.

Honestly, they have outperformed Honda in many aspects, and I say this as someone who appreciates Honda cars and drives an Acura.

It makes sense that ACC is available only in certain trims while LKA and BSM are offered with more options. Safety ratings consider LKA and BSM important features, while ACC leans more towards luxury, which costs extra.

I haven’t seen a Kia gauge cluster in some time, and if you told me this one belonged to a car from ten years ago, I would believe it.

A cheaper car typically has a cheaper interior, but their marketing materials are really setting them up for failure.

@Carmine
That advertisement is just a joke. It’s not really targeting someone looking at a BMW, it’s there to help justify the choice for buyers of Kia.

@Carmine
What’s wild is that in Korea they offer a digital gauge cluster on the higher trims.

@Carmine
This is also something I find annoying in some Genesis models too. The gauge cluster should be a significant part of the interior in a driver’s car, yet they look so plain.

The new Genesis models have greatly improved gauge clusters that even include digital displays with 3D tracking on certain trims.

@Niko
That will definitely be a positive change. The G70 is disappointing in this regard.

@Carmine
I can confirm this. I have a 2011 car with a display like that. Although the original poster doesn’t seem to be driving a high-end trim, so I didn’t expect a fully digital display.

The ACC being part of the premium package is similar to what luxury brands do. They probably did this on purpose to require more sensors for front safety features while LKA and BSM use simpler side sensors.

The exterior of the K5 looks really nice, honestly. It resembles a more refined version of the Stinger. I personally like the straightforward design of the gauge cluster. I just want to see my speed, tachometer, engine temperature, and fuel level.

@Winter
I mean, Toyota, Honda, and Subaru all offer ACC as a standard feature now. I believe that the emergency braking system included with the Kia probably uses the same hardware as the ACC since they both seem to rely on radar.

@Bali
I don’t think so. My M2 and Electric MINI have emergency braking but lack ACC because they use different radar sensors. I would assume Hyundai is doing the same to cut costs.

@Bali
This could lead to better opportunities to encourage buyers to opt for upgrades. I think the K5 is priced lower than those other stated competitors.

@Winter
ACC or Smart Cruise Control as Kia calls it should be included if the car has Lane Assist and Forward Collision Prevention. I have a Telluride LX which has SCC, and it basically drives itself on the highway. You can feel the steering wheel taking control. It supposedly uses the front-facing camera mounted on the top of the windshield. I think Kia is offering basic safety tech, collision prevention, and lane departure but wants you to upgrade to get it with the K5. Plus, the Telluride LX didn’t require any package upgrades; it just had floor mats and premium Pearl White paint.

@Marlowe
All safety features come standard on all Telluride trims. SCC is available in the GT-Line with the premium package and the EX trims for the K5. These features work using the camera near the rearview mirror while SCC uses a bumper-mounted sensor.
