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

The curb weight of the Mazda 6 III Sedan facelift 2018 ranges from 1391 kg to 1615 kg (3065 to 3561 lbs). This variation depends on the trim level and optional equipment. A lighter curb weight, closer to 1391 kg, allows for more agile handling and slightly better fuel efficiency. The heavier models, up to 1615 kg, might feel more stable and solid on the road but can have a marginally reduced fuel economy and performance due to the extra mass.

The maximum weight capacity or gross vehicle weight (GVW) of the Mazda 6 III Sedan facelift 2018 ranges from 2005 kg to 2200 kg (4422 to 4850 lbs). This figure includes the vehicle’s curb weight plus passengers, cargo, and any additional load. It's important not to exceed this maximum weight to maintain safe driving dynamics and vehicle integrity. This considerable range accommodates different configurations and ensures the vehicle can carry four to five adults and luggage comfortably within safe limits.

The luggage capacity of the Mazda 6 III Sedan facelift 2018 varies between 416 liters to 480 liters (14.7 to 16.9 cubic feet). This capacity is notably practical for a midsize sedan, accommodating large suitcases, groceries, or daily necessities easily. The variation depends on the rear seat configuration and trim level. This generous trunk space makes the Mazda 6 III suitable for families and travelers who need versatility for cargo without moving to a larger vehicle class.

The roof load limit of the Mazda 6 III Sedan facelift 2018 is 75 kg (165 lbs). This means the maximum weight that can be safely carried on the roof, such as a roof box, bike rack, or other cargo carriers, should not exceed this amount. Adhering to this limit is critical for maintaining the car’s handling stability, safety, and structural integrity during driving, especially at higher speeds or in windy conditions.

The ground clearance of the Mazda 6 III Sedan facelift 2018 is 165 mm (6.5 inches). This moderate ride height balances aerodynamic efficiency and practical everyday usability. It is sufficient for urban roads, light gravel, and mild uneven terrain without risking damage to the undercarriage. However, it is not suited for off-road driving. The ground clearance also influences the vehicle’s center of gravity and handling dynamics, providing stable and confident road manners.

Yes, the Mazda 6 III Sedan facelift 2018 will fit comfortably into a standard residential garage. Standard garages typically have widths of around 2.4 to 3.0 meters (8 to 10 feet) and heights above 2.0 meters (6.6 feet). With its width of approximately 1.84 meters (72.4 inches) and height of 1.45 meters (57.1 inches), plus its length just under 4.9 meters (about 16 feet), it fits well within the space of a single-car garage, allowing room for opening doors and walking around the vehicle.

Compared to the Mazda 6 II generation, the Mazda 6 III Sedan facelift 2018 is generally longer and slightly wider, offering a more spacious and modern design. The II generation was approximately 4750 mm in length, whereas the III extends to about 4870-4895 mm, providing extra legroom and trunk space. The width increased from roughly 1795 mm to 1840 mm, enhancing interior comfort. This size evolution reflects Mazda’s move toward a more premium midsize sedan with improved passenger comfort, cargo capacity, and road presence.

The Mazda 6 III Sedan facelift 2018 is competitively sized within the midsize sedan segment. For example, it is comparable in length and width to rivals like the Honda Accord and Toyota Camry, with length around 4.87 to 4.9 meters (about 192 inches) and width near 1.84 meters (72 inches). Its luggage capacity of 416-480 liters is slightly above average, offering good cargo space. While some competitors may offer slightly more cabin room or tech features, the Mazda 6 stands out for its stylish design and agile driving dynamics that complement its balanced dimensions.

The Mazda 6 III Sedan facelift 2018 offers rim sizes ranging from 17 inches to 19 inches (7.5J width). Tire sizes include 225/55 R17 and 225/45 R19. While these tire and rim options don't significantly alter the overall dimensions of the car's body (length, width, and height remain constant), larger rims with lower-profile tires may slightly reduce sidewall height and ground clearance. This can enhance handling and aesthetic appeal but might impact ride comfort over rough roads. Choosing between these options affects performance characteristics rather than the vehicle’s external size.
