Recently, I visited a Hyundai dealership near my home with a junior colleague who was considering purchasing a mid-size sedan.
My colleague was torn between the Hyundai SONATA, often referred to as the people's mid-size sedan, and the Kia K5.
He mentioned he was particularly drawn to the design of the Edge SONATA.
The New K5 also features a beautiful design, so we agreed to objectively compare the two models based on personal preferences.
Many people, like my colleague, often find themselves deliberating between these two models.
Today, let's compare the specifications, mock estimates, and owner reviews of both models based on the entry trim.
The New K5 has not yet received environmental certification for its hybrid model, causing delays in its announcement.
The 2024 SONATA Hybrid requires a three-month delivery period.
2024 SONATA Hybrid vs K5 Specifications and Mock Estimate Information
First, let's compare the objective information of the two models.
| | SONATA | K5 |
| Overall length (mm) | 4,910 | 4,905 |
| Overall width (mm) | 1,860 | 1,860 |
| Overall height (mm) | 1,445 | 1,445 |
| Wheelbase (mm) | 2,840 | 2,850 |
In terms of size, the SONATA is 5 mm longer in overall length but has a wheelbase that is 10 mm shorter than the K5.
This slight difference is hardly noticeable, whether visually or when sitting inside.
Both models feature the same 2.0L inline 4-cylinder engine, resulting in identical maximum output and torque.
The maximum output is 152 ps at 6,000 rpm, while the maximum torque is 19.2 kg·m at 5,000 rpm.
The tire specification is 25/65R16.
| | SONATA | K5 |
| Combined fuel efficiency (km/L) | 19.4 | 19.8 |
| City fuel efficiency (km/L) | 19.8 | 19.7 |
| Highway fuel efficiency (km/L) | 18.9 | 19.8 |
| Curb weight (kg) | 1,550 | 1,515 |
The curb weight of the Edge Sonata HEV is 35 kg heavier, which might slightly affect fuel efficiency.
While this difference may not seem significant, the variation in highway fuel efficiency is noticeable.
I plan to test drive both models in the near future and will share my experiences regarding real-world fuel efficiency.
In previous generations, the SONATA couldn't compete with the K5.
The outdated image led to its decline in popularity among younger owners.
However, the Edge SONATA has captured the attention of all generations through its bold facelift.
Typically, a facelift involves minor adjustments to the exterior design to enhance marketability, but Hyundai has taken a bold step due to poor sales performance.
On the other hand, the New K5 received praise for its refined design at the front and rear, meeting expectations.
Personally, I recommend the SONATA Hybrid between the two models because its complete redesign provides a unique driving experience without feeling common.
I have also received owner feedback on the 2024 SONATA Hybrid model, with many expressing their enjoyment of its unique appeal.
They rated it highly for its drastic changes, which completely erase the memory of previous SONATA models.
In contrast, the K5, which was already popular, seems to be saving significant changes for its next full redesign.
Another owner highlighted the sporty design and the coupe-like sleek roofline as advantages of the Edge SONATA design.Some owners also noted that it exudes a luxury feel comparable to imported cars, which lends credibility as many people share this sentiment.
For the estimates, I will proceed with the entry trims of the Edge Sonata Premium and the New K5 Prestige.
2024 SONATA Hybrid Premium Trim
The New K5 Prestige Trim
Vehicle price: 31,830,000 KRW (approximately 23,900 USD)
Acquisition tax: 1,630,000 KRW (approximately 1,230 USD)
Bond discount: 180,000 KRW (approximately 135 USD)
Mid-size sedans provide ample space suitable for families composed of adults.
Of course, if you want to enjoy camping or car camping, you should choose an SUV, but if you book accommodations like pensions or hotels, a mid-size sedan is sufficient.
Owner feedback indicates that the real-world fuel efficiency exceeds 20 km/L, making it an attractive model from an economic standpoint.
In conclusion, after thoroughly comparing the specifications and mock estimates of both models, it seems that the choice ultimately comes down to personal design preferences.
I recommend the Edge Sonata for its unique appeal through bold changes, but I suggest making a choice based on individual preferences.
The hybrid model becomes more economically advantageous the more you use it, but the actual purchase price in the mid-30 million KRW range could be a burden.
For those concerned about the upfront costs, I recommend the KS Auto Plan's long-term rental and leasing options, which allow you to use a new car without initial expenses.
KS Auto Plan partners with all major capital companies, allowing them to compare estimates based on customer conditions and situations, ultimately presenting the most affordable fees.
Many people in my circle have become customers of KS Auto Plan due to its low fees and quick delivery. As word spread, they won the Asia Economic Brand Power Award in 2020.
For those with limited driving experience, insurance premiums tend to be higher for new car purchases, but using long-term rentals allows you to benefit from lower insurance rates.
Currently, the waiting period for the 2024 SONATA Hybrid exceeds three months, but KS Auto Plan can match pre-secured inventory for delivery within a week.
For those who need a car sooner, I encourage you to contact them directly for immediate delivery.

This aspect seems similar to the recent complete redesign of the Santa Fe.
