Sonata vs K5: Interior Comfort Features 

Style makes a mark in both these midsize cars. The Sonata and K5 are dressed to the nines with stunning available seating surfaces, though you will find a difference between the availabilities. The K5 offers synthetic leather materials, that while comfortable, will not provide the type of luxurious seating experience provided by leather. On the other hand, the Sonata does offer genuine leather seating surfaces, creating a more comfortable experience on the interior.

Another difference you’ll find inside these two sedans is the lighting features. While the K5 offers LED lighting, the Sonata offers available Ambient Interior Lighting. Using this, you can toggle between 64 different colors, selecting the one that best fits the mood of your upcoming adventure.

Maybe you’ve had a long day at work and need a calming blue on the ride home? Or a vivacious green for an upcoming road trip? Whatever the case may be, you can count on the Ambient Lighting feature to lend a hand.

Space and Dimensions: Sonata vs K5

Important to the experience any sedan or smaller car can provide are the dimensions it can offer. In this area, you’ll find both the Hyundai and K5 to compare quite closely. Look to the trunk, and you’ll find that the Sonata and K5 offer identical trunk space. Utilizing the 16 cubic feet offered by either, you’ll be able to store shopping bags from your day at the mall with ease.

The similarities between the dimensions of these vehicles continue when it comes to comfort. Both the Sonata and K5 offer over 40 inches of front headroom and 46.1 inches of front legroom. So, as a driver, you’ll be quite comfortable behind the wheel of either.

Still, it is worth noting that the Sonata spreads the wealth when it comes to space, a bit better than the K5. For instance, in the rear, the Sonata offers 38.4 inches of headroom compared to just 37.8 inches in the rear of the K5. While this difference is slight, it will alter the level of comfort offered to your rear seat occupants.

Hyundai Sonata vs Kia K5: Technology To Keep You Connected 

What about technology? The Hyundai Sonata and Kia K5 both feature more than enough technology to keep both tech enthusiasts and daily drivers connected and entertained. User-friendly infotainment makes it easy to access your apps, navigation maps, and more.

Android Auto™ and Apple CarPlay^® come standard in both vehicles. They offer a simplified way to link up your smartphone with the touchscreen infotainment systems. All it takes is a swipe of the finger, and you can send messages and manage your music library.

Where the Sonata stands out is its available Hyundai Blue Link® telematics system. This state-of-the-art feature offers remote access and seamless connectivity. It will enhance your drive with:

• Remote Car Finder
• Destination Search
• On-Demand Diagnostics & Alerts
• Remote Door Lock & Unlock
• Remote Start with Climate Control

The Kia offers a similar UVO link system, though it is not as innovative or easy to use.

Driver Assistive Technologies: Sonata vs K5

Another key area to evaluate under the technology umbrella is driver-assistive technology and the suites each sedan is equipped with. In this area, you’ll find similar capabilities but different standard offerings.

For example, both the Sonata and K5 offer Smart Cruise Control systems that allow you to use the feature in heavily congested areas as well as more traditional highway settings. Though, only the Sonata comes standard with this feature. If you want it in the K5, you’ll have to upgrade.

Though, these two vehicles do come with a lot of the same standard features. For instance, you’ll find a Forward Collision Avoidance-Assist with Pedestrian Detection in both the Sonata and K5. This system will work to monitor the environment in front of your sedan, alerting you and helping you avoid potential obstructions should they present themselves. Additionally, you’ll find:

• High Beam Assist
• Rear Occupant Alert
• Available Highway Drive Assist
• Driver Attention Warning
• Lane Keeping Assist & Lane Following Assist

Sonata vs K5: Performance Specifications 

As we mentioned earlier, the Sonata and K5 share similar powertrains. Peek under the hood, and you’ll find some impressive engines. Their optional turbo 2.5L 4-cylinder engines are especially robust, with all of 290 horsepower and 311 lb-ft of torque on tap. Get up to speed in seconds—literally.

Front-wheel drive comes standard in both cars. Test drivers have found that these Kia and Hyundai cars drive smoothly over pavement and handle well. So, is there any difference between the two?

In terms of performance, there is just a slight one that comes at the base level. When equipped with their standard configurations, the Sonata comes with a 2.5L 4-cylinder engine, while the K5 comes with a 1.6L 4-cylinder engine. As these differences would suggest, it is the Hyundai Sonata that offers you more power at the ground level with 191 horsepower compared to 180 horsepower for the Kia.
