Compare in Performance and Efficiency

Choosing the right small car often comes down to two key things: how it drives and how far it goes on a tank of gas. In this sedan comparison guide, the 2025 Nissan Sentra and the Kia K4 show two different takes on what a compact car can do.

Let’s look at how they perform:

Feature	2025 Nissan Sentra	2025 Kia K4
Base Engine	2.0L 4-cylinder	2.0L 4-cylinder
Horsepower	149 hp	147 hp
Transmission	CVT	CVT, 8-speed auto (GT-Line Turbo)
Fuel Economy (est.)	Up to 34 MPG combined	Up to 33 MPG combined
Sport Trim Available?	Yes – SR model	Yes – GT-Line

The 2025 Sentra is not built for speed, but it offers a smooth, calm ride. The steering is light but tight in corners. The CVT helps keep the drive quiet and soft, even on rough roads. With its new fine-tuned rear suspension, the Sentra SR trim adds a touch of fun to your daily drive.

The K4 brings solid road feel but leans more toward comfort than sport. Both cars have about the same power. Still, many say the Sentra feels more sure on the road.

Efficiency at a Glance:

• The Sentra offers up to 40 MPG on the highway.
• The K4 trails slightly behind in most real-world tests.
• The Sentra also has Eco Mode, which helps save gas in city traffic.

When it comes to safety, the Sentra safety ratings stand strong. It includes:

• Nissan Safety Shield 360 as standard
• Forward collision warning
• Rear automatic braking
• Lane departure alert

The 2025 Sentra brings more standard driver tools than most in its class. These new features help make the drive safer and less stressful.

In short, the 2025 Nissan Sentra vs Kia K4 matchup shows how small differences add up. If you want smooth driving, great fuel use, and strong safety tools, the Nissan Sentra is hard to beat.

Comfort and Practical Interior Features

Comfort matters—whether you're stuck in traffic or on a weekend drive. When you stack up the 2025 Nissan Sentra vs Kia K4, both offer solid features. But one has the edge when it comes to smart use of space, soft seats, and easy-to-use tech.

Let’s start with space. The Sentra has a roomy back seat and a wide trunk. The K4 has more front headroom, but not much else that beats it.

Feature	2025 Nissan Sentra	2025 Kia K4
Passenger Space	96.1 cu ft	98.7 cu ft
Trunk Space	14.3 cu ft	14.6 cu ft
Touchscreen Size	8" standard	12.3" standard
Rear Seat Legroom	34.9 in	38.0 in
Available Climate Control	Dual-zone	Dual-zone

Interior Comfort and Tech Highlights:

Sentra:

• Standard Zero Gravity seats that help reduce back strain
• Dual-zone climate control on higher trims
• Soft-touch dash and door trim
• Optional leather-wrapped steering wheel
• Apple CarPlay and Android Auto standard

K4:

• Cloth or optional faux-leather seats
• Single-zone climate control on base trims
• Optional heated and cooled front seats
• Rear A/C vents on higher trims
• Large center screen, but some controls are hidden in menus

While the K4 has a sleek dash and big screen, many of its controls are touch-based. That can make it hard to adjust things while you drive. The Sentra’s setup is more user-friendly. You get physical buttons for most key features.

The 2025 Sentra new features also bring more value. Features like USB-C ports, improved seat materials, and an updated center console come standard on mid-range trims.

In this part of the sedan comparison guide, it’s clear both cars have strengths. But if you want smart design and useful comfort in a small car, the Nissan Sentra comes out ahead.

Safety Ratings and Driver Assistance

When it comes to peace of mind, safety matters. In this part of our sedan comparison guide, we take a close look at how these two sedans protect you and your passengers. Both models come with many modern safety tools, but they don't offer the same value across all trims.

The Nissan Sentra comes with more standard features, while the K4 saves a few for its higher trims. The latest 2025 Sentra new features also boost confidence on the road, especially for first-time buyers.

Here’s a quick look at how their safety tools compare:

Safety Feature	2025 Nissan Sentra (Base)	2025 Kia K4 (Base)
Forward Collision Warning	Standard	Standard
Auto Emergency Braking	Standard	Standard
Rear Cross Traffic Alert	Standard	Standard
Blind Spot Warning	Standard	Standard
Lane Departure Warning	Standard	Standard
Rear Automatic Braking	Standard	Not Available

The Sentra safety ratings are strong. It earned top marks from key groups like the IIHS in past years. While 2025 ratings are still being finalized, its crash structure and standard tools suggest it will remain a high scorer.

What the Sentra Does Best:

• Standard Safety Shield 360
• Rear auto brake that helps prevent fender benders
• Easy-to-read dash alerts
• Safety tools work well in real traffic
• Many features are standard, even on base trims

The K4 does offer advanced tools, like adaptive cruise and a highway driving assist system—but only on higher trims. That means you may have to spend more to get the same peace of mind you get standard in the Nissan Sentra.

In the 2025 Nissan Sentra vs Kia K4 match-up, safety is a big win for the Sentra. If you want smart protection without stretching your budget, it’s a standout pick.

Car Technology and Connectivity

Today’s drivers want more than just power and comfort. In-car tech plays a key role in how we drive and stay safe. Both sedans come with screens, apps, and tools that make the ride smooth. But one makes things easier right from the start.

The Nissan Sentra brings strong value with its standard tech. It keeps you linked to your phone and your world. The K4 also packs good gear, but many of its best features cost more.

Here’s a side-by-side look at what you get in base trims:

Feature	2025 Nissan Sentra	2025 Kia K4
Touchscreen Size	8-inch (Standard)	12.3-inch (Standard)
Apple CarPlay / Android Auto	Standard	Standard
Voice Commands	Standard	Standard
USB Ports	Multiple	Multiple
Bluetooth	Standard	Standard

While the K4 comes with wireless phone links right out of the gate, the Sentra holds its own with smooth voice tools, a clear screen, and simple menus. The latest 2025 Sentra new features also include easier access to system updates and app syncing.

What Sets the Sentra Apart:

• Easy-to-use display
• Clear sound from the base audio system
• Phone tools that work without lag
• Voice tools that help keep your eyes on the road
• Added options for tech upgrades across trims

If you need basic tools that just work, the Sentra is ready to go. If you want a few more wireless perks, the K4 might appeal—but only in top trims. As our sedan comparison guide shows, both give you solid options, but value and ease-of-use tip the scale in favor of the Nissan Sentra.
