If you're curious about the 2025 kia k5 lxs horsepower , you've probably noticed that Kia made a pretty bold move with the latest refresh of their popular midsize sedan. Instead of sticking with the smaller turbocharged engine we've seen in yesteryear, they decided to go bigger—literally. For the 2025 model year, the LXS trim gets a major heart transplant that changes the way the car feels when you step on the gas.
It's an interesting time for the sedan market. While everyone else is busy making their engines smaller and slapping turbos on everything, Kia went the alternative direction for the K5's base powertrain. Let's dive into what that actually means for you when you're when driving, because "more horsepower" on paper doesn't always tell the whole story of how a car actually drives on a Tuesday morning commute.
The Big Swap: Out with the Turbo, Along with the Displacement
For the last few years, if you bought a K5 LXS, you were driving around with a 1. 6-liter turbocharged four-cylinder. It had been a punchy little engine, but for 2025, Kia scrapped it in favor of a 2. 5-liter naturally aspirated four-cylinder .
Now, if you aren't a gearhead, "naturally aspirated" just means there's no turbocharger pushing extra air in to the engine. It's only the engine breathing by itself. Usually, when a car company ditches a turbo for a bigger non-turbo engine, it's because they're looking for a more linear power delivery and, quite frankly, better long-term reliability. Turbochargers add complexity and heat, and by going to a 2. 5-liter, Kia is giving the K5 a more relaxed, "big car" feel.
So, what did this do towards the numbers? The old 1. 6T produced 180 horsepower. The new 2025 kia k5 lxs horsepower jumps up to 191 horsepower . That's an 11-hp bump, which might not sound like much once you say it aloud, but in the world of daily drivers, every bit helps when you're looking to merge onto a busy highway.
Does the Extra Horsepower Actually Make it Faster?
This is where things get a bit nuanced. While the horsepower went up, the torque actually shifted a bit too. The 2025 K5 LXS puts out 181 lb-ft of torque . If you compare that towards the old engine, it's actually a tiny bit less torque than the turbo offered, and more importantly, that torque comes in later in the rev range.
When you drive the 2025 K5 LXS, you'll notice that the ability feels "smoother. " With a turbo, you often get a little lag—that split second where nothing happens prior to the car suddenly lunges forward. With the new 2. 5-liter engine, the response is more immediate but also more gradual. It feels more like a traditional sedan. It's predictable, steady, and honestly, a bit more refined for the average person who just wants to be able to work without any drama.
Is it a speed demon? No, definitely not. But with 191 horses under the hood, the LXS is more than capable of holding its own against the heavy hitters like the Toyota Camry or the Honda Accord. It feels confident, and that's really what you want in this class of vehicle.
The 8-Speed Automatic: A Smooth Operator
One thing I'm really glad Kia kept (and refined) will be the 8-speed automatic transmission . Some of the K5's competitors use CVTs (Continuously Variable Transmissions), which can sometimes feel like you're driving a rubber band—they drone and can feel a bit disconnected.
The 8-speed in the 2025 K5 LXS works perfectly with the 191 horsepower. It shifts cleanly and knows exactly which gear to be in to make the most of that naturally aspirated power. If you need to pass someone, the transmission drops a couple of gears quickly, and the engine sings its way up the tachometer. It's a very "human" feeling drive compared to the somewhat synthetic feel of the CVT.
Why the LXS Trim is the Sweet Spot
When people discuss the K5, they generally get distracted with the GT trim—that's the one with nearly 300 horsepower and all the bells and whistles. But let's be real: most people don't need a track-ready sedan. They need something which looks cool, stays reliable, and doesn't break the bank at the gas pump.
The LXS is the "entry-level" trim, but it doesn't feel like a base model. Because it shares the same 2. 5-liter engine as the higher mid-tier trims (like the GT-Line), you're getting the same performance without paying the premium for any sunroof or fancy leather seats in case you don't want them. You're getting that 2025 kia k5 lxs horsepower at the best possible price point.
Plus, the LXS is actually a bit lighter compared to higher trims since it has fewer heavy electronic components. Sometimes, a lighter car with the same engine can feel just a touch more agile, which is a nice little bonus for the budget-conscious buyer.
Fuel Economy: The Trade-off
You'd believe that moving to a bigger engine would absolutely tank the fuel useage, right? Usually, that's the case. But Kia did some pretty impressive engineering here. Even with the jump to 191 horsepower, the 2025 K5 LXS remains incredibly efficient.
You will probably see somewhere in the neighborhood of 30 combined MPG . On the road, it's even better. This is the beauty of a modern naturally aspirated engine paired with an 8-speed gearbox; it can cruise at low RPMs, sipping fuel, but still provide you with that 191-hp kick when you actually need to go. It's a "best of both worlds" scenario that makes the K5 a really strong contender for anyone with a long commute.
Handling the 191 Horses
Horsepower is only half the battle; you've also got to consider how the car handles that power. The 2025 K5 LXS is front-wheel drive, and it feels very planted. The steering includes a nice weight to it—not too light that it feels like a toy, but not so heavy that it's a chore to park.
Since the power delivery is so linear now, you don't get just as much "torque steer" (that's when the steering wheel tugs to one side under hard acceleration) as you might have with the old turbo. It's an extremely composed experience. Whether you're navigating a rainy city street or an open stretch of interstate, the K5 LXS seems like it's punching slightly above its weight class in terms of sophistication.
Is It Enough Power for You?
At the end of the day, 191 horsepower is plenty for 90% of drivers. If you're coming from an old car, the 2025 kia k5 lxs horsepower will feel like a significant upgrade. It's enough to get you up to speed on an on-ramp without breaking a sweat, and it's enough to hold a full load of passengers and groceries without the car feeling bogged down.
If you're a person who wants to be pushed back into your seat every time the light turns green, you might want to go through the GT. But for everybody else? The LXS hits that "just right" mark. It's reliable, it's predictable, and it's got just enough pep to make driving actually enjoyable rather than just a chore.
Final Thoughts on the 2025 Refresh
Kia could have easily just left the K5 alone for another year, but this engine change shows they're actually listening to what people want. By bumping up the 2025 kia k5 lxs horsepower and moving to a larger displacement engine, they've a new car that feels more substantial and durable.
It's a stylish sedan that doesn't just look fast—it has got the mechanical backbone to back up its aggressive styling. If you're in the market for a new ride this year, don't sleep on the LXS. It might be the base trim, but with 191 horsepower and a smooth 8-speed automatic, it's anything but basic. It's a solid, well-rounded machine that proves you don't need a turbocharger to have a little bit of fun on the road.
