2012 Honda N-One I Dimensions, Size & Specs

The curb weight of the Honda N-One I varies between 830 and 900 kg (approximately 1829 to 1984 pounds). This lightweight construction contributes to its agility, easy handling, and overall driving dynamics. A lighter car requires less power to accelerate, which improves fuel efficiency and reduces emissions. The relatively low weight also helps the N-One I make good use of its small engine under kei car regulations, balancing performance and economy, ideal for city commuters.

The Honda N-One I has a ground clearance ranging from 150 mm to 155 mm (approximately 5.9 to 6.1 inches). This moderate ride height is suitable for smooth urban and suburban roads, providing a balance between ease of entry and exit, as well as road visibility. The ground clearance is sufficient for most city speed bumps and uneven pavement but might be limiting on rough or off-road terrain. The ride height helps maintain a lower center of gravity, contributing to stable handling.

Yes, the Honda N-One I fits comfortably in a standard garage. With its length of 3395 mm (133.7 inches) and width of 1475 mm (58.1 inches), the car is well within the average garage space dimensions seen worldwide. Most standard single-car garages typically measure at least 2.4 meters (7.9 feet) or wider and about 5 meters (16.4 feet) in length, giving ample room for parking the N-One I alongside some extra space for opening doors and maneuvering around the vehicle.

The Honda N-One I was introduced as part of Honda’s renewed focus on fashionable and retro-inspired kei cars, following the N-Series lineage which includes models like the Honda N-Box and N-WGN. Compared to some earlier kei models, the N-One I emphasizes a compact and squared design, retaining the limits imposed by kei car regulations—length up to 3400 mm and width up to 1480 mm. While earlier kei cars from Honda might have been more utilitarian or boxy, the N-One offers a blend of nostalgic styling and efficient packaging without growing in size, keeping it ideally compact but stylishly modern.

In comparison to other kei cars by manufacturers such as Suzuki (e.g., Suzuki Alto) or Daihatsu (e.g., Daihatsu Move), the Honda N-One I is very competitive in size. It adheres to kei car dimension limits with a length just under 3400 mm and a width under 1480 mm, similar to its rivals. Height varies a bit more, but overall, the N-One’s compact footprint provides excellent urban usability, which is typical in this segment. Unique styling and quality interiors distinguish it from competitors while offering similar maneuverability, parking ease, and fuel efficiency.

The Honda N-One I comes with two main rim size options: 14-inch and 15-inch wheels. Corresponding tire sizes include 155/65 R14 and 165/55 R15. The 14-inch tires typically provide a slightly softer ride quality due to taller sidewalls, absorbing bumps better on uneven urban roads. The 15-inch wheels, with lower profile tires, offer a sportier feel and improved cornering performance but may transmit more road vibration. Overall, both setups balance ride comfort and nimble handling suitable for city driving.

Despite its compact exterior size, the Honda N-One I is cleverly designed to maximize usable interior space. The tall height (up to 1630 mm or 64.2 inches) allows for good headroom for front and rear passengers. The boxy design also helps provide decent shoulder room and legroom within the constraints of kei car regulations. While it’s a 4-seater with a small cabin footprint, the interior offers practicality with configurable rear seats and clever storage solutions, making it well-suited for city dwellers who need a small but versatile vehicle.

The Honda N-One I, although primarily designed as a city and commuter vehicle, can handle highway driving fairly well within the limits of its kei car classification. Its lightweight construction (around 830-900 kg) and compact size contribute to responsive handling and low fuel consumption. However, due to its smaller engine capacity (restricted by kei car rules) and lighter weight, it may feel less powerful at higher speeds and can be more affected by strong crosswinds. It is best suited for moderate highway speeds and shorter highway trips rather than extended high-speed cruising.

The Honda N-One I is well-regarded for its balance of performance and efficiency within the kei car segment. Powered typically by a small 660cc engine (as dictated by kei car regulations), the N-One provides adequate performance for city use, with smooth acceleration and easy maneuverability. Fuel efficiency is excellent, often achieving around 20-25 km/l (approximately 47-59 mpg US), depending on driving conditions and transmissions (available in manual or CVT). This efficiency, along with compact dimensions and low weight, makes it an ideal urban vehicle with low running costs.
