2015 Toyota Mirai Dimensions, Size & Specs

The curb weight of the 2015 Toyota Mirai is approximately 1850 kg (4079 lbs). This refers to the weight of the vehicle with all standard equipment, fluids, and ready to drive but without passengers or cargo. The maximum authorized weight, which accounts for the maximum load including passengers and cargo, is 2180 kg (4806 lbs). This relatively high weight is due in part to the hydrogen fuel cell system and associated tanks.

The first-generation Toyota Mirai has a ground clearance of 130 mm (5.1 inches). This is somewhat lower than typical SUVs but fairly standard for sedans. The lower ride height helps improve aerodynamics and stability, which is important for a fuel cell vehicle focusing on efficiency. However, it may limit traversal over rough or uneven terrain where higher ground clearance is beneficial.

The 2015 Toyota Mirai provides a luggage compartment capacity of 361 liters (about 12.7 cubic feet). This trunk space is reasonable for a mid-sized sedan and is sufficient for carrying everyday luggage such as suitcases, groceries, or gym bags while maintaining the layout for hydrogen fuel storage.

The 2015 Toyota Mirai is equipped with 17-inch rims paired with tires sized 255/55 R17. These relatively wide tires contribute to the car's stability and road grip, especially given the vehicle's unique weight distribution due to its hydrogen fuel cell powertrain.

The 2015 Toyota Mirai, with its length of 4890 mm (192.5 inches) and width of 1810 mm (71.3 inches), generally fits comfortably within a standard residential garage. Typical garage interior dimensions are around 5500 to 6000 mm (216 to 236 inches) in length and 3000 mm (118 inches) in width, so the Mirai fits with some clearance on all sides. However, owners should verify their garage dimensions to ensure sufficient space for door opening and walking around the vehicle.

The first-generation Toyota Mirai (2014-2020) does not have a direct predecessor within Toyota’s lineup as it was the brand’s pioneering production hydrogen fuel cell vehicle. Prior models like the Toyota FCHV (Fuel Cell Hybrid Vehicle) were prototypes or limited production experiments rather than mass-market sedans. Therefore, the Mirai set new standards for size, offering a mid-sized sedan footprint with 4890 mm length, optimized for passenger comfort and hydrogen storage, unlike the smaller, less refined earlier experimental fuel cell models.

Compared to other hydrogen fuel cell vehicles of its time, such as the Hyundai Tucson Fuel Cell or the Honda Clarity Fuel Cell, the Mirai is generally larger in length (4890 mm vs. approximately 4600 mm for the Clarity). The wider stance (1810 mm) supports stability, and its overall sedan profile is more conventional compared to niche styling of competitors. When placed alongside electric sedans, the Mirai’s size aligns closely with mid-sized luxury and eco-friendly sedans, balancing interior space and road presence with efficient hydrogen fuel storage.

The dimensions of the Toyota Mirai are carefully designed to optimize aerodynamic efficiency, crucial for maximizing the range and performance of this hydrogen fuel cell vehicle. Its length of nearly 4.9 meters (192.5 inches) and moderate width reduce drag while allowing space for a streamlined body shape. The relatively low height of 1535 mm (60.4 inches) helps reduce frontal area. Together with design features like smooth underbody panels and aerodynamic side mirrors, these dimensions help reduce air resistance, enhancing fuel efficiency and reducing energy consumption during driving.

The first-generation Toyota Mirai, at about 4.89 meters (192.5 inches) long and 1.81 meters (71.3 inches) wide, is a mid-sized sedan that generally handles well in city environments. While its length is on the longer side for tight urban spaces, it is comparable to many luxury sedans and should provide adequate maneuverability with modern steering and parking assist features. The ride height of 130 mm (5.1 inches) does not impact city driving negatively. Its size allows for comfortable passenger space while maintaining reasonable access to parking spaces and narrow streets common in urban areas.
