These dimensions provide a sleek profile typical of the CLA range, combining aerodynamic efficiency with a modern aesthetic. The car's width contributes to a stable stance on the road while its modest height offers a low center of gravity, enhancing handling dynamics. Overall, the size helps balance interior comfort and urban maneuverability, making it ideal for drivers seeking a stylish yet practical luxury sedan.

Inside the 2026 CLA Saloon (C178), Mercedes-Benz has optimized passenger space to deliver comfort within its compact luxury sedan footprint. Although exact interior dimensions can vary by trim and optional equipment, the CLA comfortably seats up to five occupants with ample legroom and headroom for front passengers. Rear seat space is slightly more cozy but remains competitive for the segment. The interior width allows passengers enough shoulder room to avoid feeling cramped during daily commutes or longer journeys. The well-designed cabin layout also incorporates premium materials and advanced technology, creating an inviting atmosphere despite the CLA’s relatively compact exterior size.

The 2026 Mercedes-Benz CLA Saloon offers a practical trunk space with a volume of approximately 460 liters (16.2 cubic feet). This capacity is quite generous for the compact luxury sedan class, allowing owners to comfortably carry luggage, groceries, or sports gear. The trunk opening is designed for easy loading and unloading, and the rear seats can fold down to expand the cargo area when needed. This versatility makes the CLA a compelling choice for those who prioritize both style and utility in their vehicle.

The 2026 Mercedes-Benz CLA Saloon fits comfortably inside a standard garage. Considering typical residential garages are around 6 meters (20 feet) in length and 2.5 to 3 meters (8 to 10 feet) in width, the CLA's length of 4,688 mm (184.6 inches) and width of 1,830 mm (72.0 inches) provide sufficient clearance for easy parking and door opening. This makes the CLA suitable for urban residents who need a stylish luxury sedan without worrying about garage fitment issues.

The 2026 Mercedes-Benz CLA Saloon (C178) is engineered with lightweight materials and modern construction techniques, resulting in a curb weight typically ranging from around 1,450 kg to 1,600 kg (3,197 to 3,527 lbs) depending on the trim and equipment levels. Compared to its predecessor, the first-generation CLA (C117, produced from 2013 to 2019), the 2026 model generally maintains a similar weight profile but benefits from advancements in material science, potentially offering better weight distribution and marginal weight savings. This contributes to improved driving dynamics, fuel efficiency, and overall performance while preserving the vehicle's structural integrity and safety.

The 2026 Mercedes-Benz CLA Saloon has a turning radius of approximately 5.3 meters (17.4 feet), which is relatively tight for a luxury sedan. This compact turning circle enhances maneuverability in confined urban environments, making parking, U-turns, and navigating narrow streets easier and less stressful. The tight turning radius complements the CLA's responsive steering system, contributing to a nimble driving experience that benefits city commuters and those who frequently drive in congested areas.

Dimensionally, the 2026 CLA Saloon (C178) builds upon the foundation set by the first generation CLA (C117). The newer model is slightly longer and wider, supporting a more spacious interior and greater road presence. For example, the C117 measured about 4,630 mm (182.3 inches) in length, whereas the C178 extends to approximately 4,688 mm (184.6 inches). Width also increased slightly from around 1,777 mm (69.9 inches) to 1,830 mm (72.0 inches), improving shoulder room for occupants. Beyond size, the 2026 CLA integrates enhanced technology, safety systems, and modern styling cues reflecting Mercedes-Benz’s latest design language. These improvements translate into a more refined and comfortable driving experience with upgraded connectivity, driver assistance, and efficiency compared to the predecessor.

When compared with other luxury compact sedans, such as the Audi A3 Sedan, BMW 2 Series Gran Coupe, and Lexus IS, the 2026 Mercedes-Benz CLA Saloon holds its own with a slightly longer and wider body, which translates to competitive interior space and road presence. For instance, the Audi A3 Sedan typically measures around 4,495 mm (177 inches) in length, making the CLA noticeably longer at 4,688 mm (184.6 inches). The width of 1,830 mm (72.0 inches) also positions the CLA among the wider vehicles in this segment. This dimensional advantage often results in more passenger comfort and cargo capacity, while the CLA’s distinct Mercedes-Benz styling and rich features set it apart in terms of luxury and appeal.

The 2026 Mercedes-Benz CLA Saloon has a height of approximately 1,437 mm (56.6 inches), providing a sleek, coupe-like roofline that enhances aerodynamic performance and aesthetic appeal. The vehicle's ground clearance is generally around 130 mm to 150 mm (5.1 to 5.9 inches), which is standard for a luxury compact sedan and suitable for urban and highway driving conditions. This balance ensures the car offers a sporty stance without sacrificing everyday usability or the ability to navigate speed bumps and uneven pavement effectively.
