The curb weight of the Kia Optima IV ranges from 1455 kg to 1705 kg (approximately 3209 lbs to 3759 lbs), depending on the specific trim and equipment. The maximum permissible weight, or gross vehicle weight rating (GVWR), falls between 2000 kg and 2200 kg (4409 lbs to 4850 lbs). This range ensures a robust structural design that supports both passenger comfort and cargo capacity while maintaining good performance and safety standards.

The Kia Optima IV offers a luggage capacity ranging from 307 liters (10.8 cubic feet) to 510 liters (18.0 cubic feet), depending on whether the rear seats are up or folded down. This flexibility accommodates everyday needs such as grocery shopping, luggage for trips, or transporting larger items like sports equipment. The trunk space is well-designed to be accessible and practical, making the Optima IV a practical choice for families and commuters.

The Kia Optima IV features a ride height or ground clearance of 135 mm (5.3 inches). This clearance level strikes a balance between ride comfort, sporty handling, and the ability to manage rougher road surfaces or minor obstacles without scraping. It contributes to a stable driving experience but is not designed for off-road use, making it ideal for city streets and highways.

Yes, the Kia Optima IV is designed within the typical size constraints to fit comfortably into a standard residential garage. With a length of 4855 mm (191.1 inches) and a width of 1860 mm (73.2 inches) without mirrors, it allows sufficient clearance on most garage dimensions. However, with mirrors open, the width extends to 2120 mm (83.5 inches), so it is advisable to fold the mirrors when parking in tighter spaces. The height of 1465 mm (57.7 inches) easily fits under standard garage ceiling heights.

The Kia Optima IV measures 1860 mm (73.2 inches) in width without the mirrors extended. When the side mirrors are opened, which is their normal driving position, the total width increases to 2120 mm (83.5 inches). This is a significant difference of 260 mm (10.2 inches) and is important for parking considerations, narrow roads, or garage entry. Drivers should be mindful of mirror position in confined spaces to avoid potential scrapes or damage.

The Kia Optima IV offers a range of wheel rim sizes including 16-inch, 17-inch, and 18-inch rims, with specific dimensions like 7J x 17, 6.5J x 16, 7.5J x 17, and 7.5J x 18 inches. Tire sizes vary accordingly, with options like 215/60 R16, 215/55 R17, and 235/45 R18. These choices provide a balance between ride comfort, handling precision, and aesthetic appeal for different trims and driving preferences.

Compared to the third-generation Optima, the fourth-generation Kia Optima (2015-2018) is generally larger, reflecting the trend toward more spacious midsize sedans. The Optima IV increased in length and width, offering enhanced interior space and better comfort for passengers. For example, the Optima III had a length of around 4800 mm, slightly less than the Optima IV's 4855 mm, and a narrower width. These size changes improved legroom and trunk capacity, elevating the car’s competitiveness in its segment.

When compared with competitors like the Honda Accord, Toyota Camry, and Hyundai Sonata from the same period, the Kia Optima IV holds a competitive position in terms of dimensions. Its length of 4855 mm (191.1 inches) and width of 1860 mm (73.2 inches) are very similar to these rivals, offering ample passenger room and cargo capacity. The Optima’s slightly sportier styling and efficient use of space are considered strengths, providing a balance between comfort and driving dynamics in the midsize sedan category.

The Kia Optima IV is rated with a roof load capacity of 100 kg (220 lbs), which allows it to carry roof racks, cargo boxes, or sporting equipment like bicycles and skis safely. Roof load should never exceed this limit to maintain safe handling and avoid damage to the car’s structure. This capacity makes the Optima IV versatile for outdoor activities and travel needs that require extra cargo space beyond the trunk.
