My Honest Review of the 2021 Kia K5

I have never used Toyota’s setup, but once you get used to the technology, you won’t want to drive without it. My Subaru sometimes gets confused and tracks a car moving to the right lane, but it never slams on the brakes.

It has really reduced the stress of driving during rush hour for me.

This really depends on the technology used. My Mazda doesn’t slow down very aggressively and doesn’t mind closing gaps, but once there’s a gap, it accelerates immediately. My mom’s Acura is quite aggressive with maintaining the gap during both acceleration and deceleration.

I absolutely love the adaptive cruise control in my 2020 Outback. Living in LA, it makes driving so much less tiring. My Outback allows me to set how aggressively it speeds up or slows down and the distance between my car and the car ahead. It performs well at both normal highway speeds and in stop-and-go situations. Nowadays, I just have to get it to the freeway and then I can relax.

It definitely depends on the system. Personally, I don’t care about ACC. I had it in a previous car but hardly used it, so I didn’t get it for my current one. It can be useful in moderate traffic, but otherwise, I find it not very beneficial.

Still, there are clear differences in systems. I haven’t found a mainstream car brand with a decent ACC system. Volkswagen, Toyota, and Honda have such poor systems that leave too much distance, are jerky with lane correction, and respond too harshly to other vehicles. Subaru and Nissan are generally okay, but a bit too careful if you live in traffic. BMW had bad ACC for a long time, but I hear it’s improved. Tesla and Mercedes-Benz have exceptional systems though. I believe Supercruise is also very good.

I drove a 2018 BMW and decided to stay away from them. Then I tried a 2020 Impreza and I love it.

It varies depending on the manufacturer, year, and vehicle model. We didn’t get the feature on our 911 because I felt like not being involved with the car missed the point. My wife pointed out that ACC in a truly fast car can be risky with a radar system. I wouldn’t want to pay extra for it on a full-size truck for that reason.

I’ve seen the Taco’s ACC in action and it’s terrible—not accurate at all. The systems in new Hyundais look good. Honda’s seems sluggish.

I really enjoy it on my Kona. I barely need to do anything on highway drives. It closes distances well, especially at lower speeds, and then keeps the gap as we approach target speeds, so it doesn’t leave too much room in stop-and-go conditions.

That’s why you add open pilot to enhance it and achieve a level 2 autonomy similar to Tesla.

Kia has been rated among the best for ACC regarding its smoothness and human-like driving.

@Winter
Is there a hybrid or plug-in hybrid version of this car?

Nope, that’s only the Sonata.

From what I’ve seen in reviews, Hyundai and Kia have one of the top systems in the market outside of the higher-end luxury systems.

@Winter
I bought a gray K5 with red interior in AWD. While I wouldn’t say it’s fast, it’s definitely not slow either. It has enough power to get you into some trouble, for sure. The design is beautiful. Everyone seems to love it. If I could suggest, I would at least test out the 2.0T with 220hp.

The GT doesn’t have AWD, which was a deal breaker for me.

Overall, I’m happy with the car.

I will say that below 2500 RPM it feels weak.

That’s surprising.

That’s surprising.

This is because of the small 1.6L engine. Without the turbo, it would likely produce around 120-130HP. I mention this because when driving around town, it often stays under 2k RPM. In normal mode, pressing the gas didn’t make it downshift immediately, so it wasn’t quick enough to make a lane change as I’d hoped. Larger engines tend to have more torque for this kind of situation. Sport mode does help, but I doubt the average driver will leave it in sport mode.

That’s surprising it feels weak. In my car, I hit max torque at 1800 and it takes off regardless of the gear.

You could probably remap the ECU to adjust that torque curve.

The official specs say max torque kicks in at 1500RPM. I’m basing my take on my experience that it needed to downshift to comfortably pass other cars.

@Bali
What’s the peak torque level?
