Comparison Review

Comfort
Passengers in the back seat will be able to stretch out a lot more in the Kia K4 than the Hyundai IONIQ 6, due to its greater head- and legroom. The Hyundai IONIQ 6 will be a favorite with taller drivers due to its greater front head- and legroom than the Kia K4.

Cost
There are a lot of factors to consider when calculating the overall cost of a vehicle. The main consideration is Manufacturer's Suggested Retail Price (MSRP). The Hyundai IONIQ 6 will definitely make more of a dent in your wallet than the Kia K4, which has a much lower MSRP.

Dimensions
The Hyundai IONIQ 6 is a little wider than the Kia K4, so getting in and out of the car in a crowded parking lot may be a little more of a squeeze. For some people, bigger is better. If that's the case for you, then you'll be happier with the Hyundai IONIQ 6, which is slightly longer than the Kia K4.

Handling
The Hyundai IONIQ 6 has a significantly larger turning radius than the Kia K4, making it much more difficult to maneuver in and out of tight spots.

Performance
When it comes to horsepower, the Hyundai IONIQ 6 has a much more powerful engine than the Kia K4. However, something you should consider is that higher horsepower engines often command higher insurance premiums.

Powertrain
The Hyundai IONIQ 6 has much less torque than the Kia K4, which generally means that it won't feel as fast or powerful.

Utility
In terms of seating you'll be able to fit the same number of people in both the Hyundai IONIQ 6 and the Kia K4.
