2023 Sono Motors Sion Dimensions, Size & Specs

The curb weight of the 2023 Sono Motors Sion is 1730 kilograms (3816 pounds). This reflects the vehicle's weight when empty, including standard equipment and necessary operating consumables like oil and coolant. Its maximum permissible weight, which includes passengers, cargo, and everything aboard, is 2180 kilograms (4806 pounds). This maximum weight rating ensures safe handling and performance standards, factoring in full occupancy and luggage capacity.

The 2023 Sono Motors Sion hatchback offers a practical luggage capacity of 650 liters (22.9 cubic feet) with the rear seats in their upright position, enabling everyday usage such as groceries or carry-on luggage. When the rear seats are folded down, the cargo space expands significantly to 1250 liters (44.1 cubic feet), allowing for the transport of larger items or increased cargo volume, making it versatile for various loading needs.

The Sono Motors Sion features a ride height or ground clearance of 165 mm (approximately 6.5 inches). This clearance is sufficient for smoothly handling most urban and suburban road surfaces, including speed bumps and mild potholes. While it maintains a low stance for aerodynamic efficiency and stability, the clearance may be less suitable for very rough off-road terrains, where higher ground clearance would typically be preferable.

The 2023 Sion is equipped with tires sized 205/60 R16. This specification means the tires are 205 mm wide, with a sidewall height that is 60% of the tire width, mounted on 16-inch diameter wheels. This tire size helps provide a good balance between ride comfort, handling, and efficiency, suited to the hatchback's design and performance targets.

With a length of 4470 mm (176 inches) and a width of 1830 mm (72 inches), the Sono Motors Sion fits well within the dimensions of a typical residential garage, which often measures about 6 meters (20 feet) in length and 3 meters (10 feet) in width. The key consideration is the opened mirror width of 2080 mm (82 inches) — drivers will need enough side clearance when the mirrors are extended. Generally, the Sion's compact hatchback form allows for comfortable garage parking in most standard home setups.

The 2023 Sono Motors Sion represents the first and current generation of this model, as the Sion is a newly developed fully electric solar-assisted hatchback with no predecessor from Sono Motors for direct comparison. It introduced innovative solar integration on body panels to support battery charging. Therefore, compared to conventional predecessors from other brands, the Sion marks a significant step forward in combining electric mobility with solar technology within a compact and practical hatchback footprint.

The Sion's length of 4470 mm (176 inches) and width of 1830 mm (72 inches) position it slightly larger than some compact electric hatchbacks like the Nissan Leaf or Renault Zoe but smaller than mid-size electric SUVs. Its luggage capacity of 650 liters (22.9 cubic feet) with seats up is competitive, offering more space than many smaller EV hatchbacks, while its solar panel integration provides a unique feature set. The Sion blends practicality and eco-innovation within a size that balances urban driving ease and cabin versatility.

The Sono Motors Sion stands out for its integration of photovoltaic solar cells embedded into its body panels, enabling it to generate additional electric range from sunlight — a distinctive feature that supports sustainability and energy efficiency. While exact driving range depends on conditions, this technology aims to reduce reliance on traditional charging. With its modest curb weight of 1730 kg and efficient electric drivetrain, the Sion is designed for urban and suburban mobility with an eco-friendly focus.

The Sono Motors Sion offers a practical hatchback layout with ample interior space for small families. Its 1660 mm height (65 inches) provides comfortable headroom, and the generous luggage capacity—650 liters (22.9 cubic feet) with seats up—allows for carrying everyday family gear. When more space is needed, folding the rear seats boosts capacity to 1250 liters (44.1 cubic feet). The car’s overall size supports easy maneuverability in urban environments while providing comfortable accommodation for passengers and cargo.
