2018 Mazda 6 III Sport Combi (GJ, facelift 2018) Dimensions, Size & Specs

The Mazda 6 III Sport Combi offers a generous luggage capacity of 522 liters (18.4 cubic feet) with the rear seats in their upright position. When you fold down the rear seats, the luggage space expands significantly to 1664 liters (58.8 cubic feet). This substantial cargo volume makes the Sport Combi an excellent choice for carrying bulky items, long trips, or larger hauls, providing versatility for everyday needs as well as recreational activities.

The Mazda 6 III Sport Combi has a ride height or ground clearance of 165 mm (6.5 inches). This clearance strikes a balance between a sporty, low center of gravity ideal for dynamic driving and sufficient height for navigating typical road obstacles such as speed bumps and light rough terrain. While it's not designed for off-road use, this ground clearance suffices for most urban and suburban conditions, providing stability and confident handling.

The maximum permissible weight of the Mazda 6 III Sport Combi ranges between 2042 kg and 2260 kg (4501 to 4980 lbs), depending on the exact model and configuration. This figure includes the vehicle's curb weight as well as passengers, cargo, and additional equipment. The difference between maximum weight and curb weight represents the usable payload capacity, which allows carrying several passengers and substantial luggage without compromising safety or performance.

The Mazda 6 III Sport Combi is 1840 mm (72.4 inches) wide without mirrors and 2090 mm (82.3 inches) wide with mirrors open. Standard residential garages typically have door widths around 2400 to 2700 mm (94.5 to 106.3 inches), so the vehicle fits comfortably with mirrors extended. With mirrors folded, it offers even easier access. Therefore, it fits well into standard garages, but drivers should be mindful when opening doors or maneuvering in tight spaces because of its width.

The Mazda 6 III Sport Combi's width of 1840 mm (72.4 inches) places it comfortably within the typical range for mid-size station wagons. Competing models like the Volkswagen Passat Variant or the Skoda Superb Combi have similar widths, generally ranging from 1800 mm to 1850 mm (70.9 to 72.8 inches). This width balances interior space for passengers and cargo with manageable dimensions for daily driving and parking, positioning the Mazda competitively in terms of size within its segment.

The roof load capacity for the Mazda 6 III Sport Combi is 75 kg (165 lbs). This rating allows owners to safely attach roof racks for carrying bikes, roof boxes, skis, or other cargo without risking damage or compromising vehicle safety. It's an important specification for users planning extended trips or outdoor activities that require additional storage space beyond the generous trunk volume.

Compared to its predecessor, the Mazda 6 II, the 2018 facelifted Mazda 6 III Sport Combi is longer and slightly wider, enhancing interior space and cargo capacity. The length of the 6 III is 4805 mm (189.2 inches), noticeably longer than the previous generation, which translated into more passenger legroom and increased luggage space—522 liters vs. approximately 490 liters in the predecessor. Additionally, the 6 III facelift brought design updates, improved tech features, and refined driving dynamics, making it more modern and attractive for long-term ownership.

The Mazda 6 III Sport Combi compares favorably against popular rivals such as the Volkswagen Passat Variant and Ford Mondeo Estate. Dimensionally, it is similar in length (4805 mm vs. around 4760 mm for Passat), slightly wider than some competitors, and offers competitive luggage capacity at 522 liters (in a standard configuration). In terms of practicality, it balances sporty driving dynamics with usable interior and cargo space. Its lower ride height compared to some rivals favors driving feel but may slightly reduce ease over rough terrain. Overall, it is an excellent choice for buyers seeking a stylish, spacious station wagon with dynamic handling.

The curb weight of the Mazda 6 III Sport Combi ranges from 1399 kg to 1635 kg (3084 lbs to 3606 lbs). This variation is influenced by factors such as engine choice, transmission type, trim levels, optional features, and drivetrain configuration. Heavier versions tend to include all-wheel drive systems, more luxurious equipment, or larger engines, while lighter variants focus on efficiency and base features. This broad weight range affects fuel efficiency, handling, and performance, allowing buyers to select a model that best fits their driving preferences and needs.
