2015 Honda S660 Dimensions, Size & Specs

The Honda S660 has a curb weight ranging between 830 kg and 850 kg (approximately 1830 to 1874 pounds). This lightweight construction is crucial for maximizing the car's agility, fuel efficiency, and handling dynamics. A lower curb weight means the engine doesn't have to work as hard to propel the vehicle, resulting in brisk acceleration and responsive driving characteristics. Additionally, the reduced mass contributes to better braking performance and cornering stability, making the S660 a fun and engaging roadster despite its small engine displacement.

The Honda S660 has a ground clearance of 125 mm (about 4.9 inches). This relatively low ride height is typical for sports cars and roadsters, helping to lower the center of gravity for improved handling and stability during high-speed cornering. However, the low ground clearance means the car is best suited for smooth paved roads rather than rough terrains or uneven surfaces. Drivers should exercise caution on speed bumps, steep driveways, or poorly maintained roads to avoid scraping the underside.

Yes, the Honda S660 fits comfortably into a standard home garage. With its length of 3395 mm (133.7 inches or roughly 11.1 feet), width of 1475 mm (58.1 inches or about 4.85 feet), and a low height of 1180 mm (46.5 inches or about 3.9 feet), it occupies much less space compared to typical family cars or larger vehicles. Most residential garages, which usually have door widths of around 2.4 meters (7.9 feet) and depths of 5.5 meters (18 feet) or more, can easily accommodate the S660, allowing space for opening doors and moving around the vehicle within the garage.

The Honda S660 is a standout among kei cars and small roadsters due to its sporty design and roadster format. Compared to other kei cars, which are generally focused on practicality, the S660’s dimensions—3395 mm length, 1475 mm width, and 1180 mm height—are very much within the kei car regulatory limits in Japan, but with a lower stance emphasizing performance. Relative to similarly sized roadsters, it tends to be smaller and lighter, giving it a more agile driving experience. For instance, compared to the Mazda MX-5 Miata, the S660 is shorter and narrower, making it ideal for tight city environments but with less interior space.

The Honda S660 does not have a direct predecessor as it marked Honda’s re-entry into the kei sports car segment after a long hiatus following the Honda Beat from the early 1990s. Compared to the Honda Beat, the S660 is slightly more modern in design and engineering but remains similar in size and weight to comply with kei car regulations. The S660’s dimensions—3395 mm length, 1475 mm width, and 1180 mm height—and curb weight between 830-850 kg represent incremental improvements for a sportier, lighter feel. Its compactness and low weight position it well within the traditional kei car size limits while offering enhanced driving dynamics compared to older models.

The Honda S660 comes equipped with rims in sizes 15 and 16 inches, depending on the trim and specific configuration. The corresponding tire sizes are 165/55 R15 75V for the 15-inch rims and 195/45 R16 80W for the 16-inch rims. These tire sizes complement the S660’s lightweight and compact dimensions by offering a good balance between grip and ride comfort. The relatively narrow and low-profile tires help maintain precise handling characteristics and enhance the sporty driving experience favored by enthusiasts.

Given its classification as a kei roadster, the Honda S660 prioritizes nimble performance and compactness over spaciousness. The small exterior dimensions translate to a cozy cabin designed for two occupants with limited legroom and headroom relative to larger vehicles. Cargo capacity is also minimal, offering just enough space for small bags or essentials. While the compact size helps in tight urban driving and parking, buyers should be aware that the cabin and storage space are constrained, making the S660 best suited for short trips and sporty driving rather than extended travel or cargo hauling.

The Honda S660’s low height of 1180 mm (46.5 inches) and sleek roadster bodywork contribute positively to its aerodynamic profile and on-road stability. The low stance helps reduce drag and improves airflow over the car's body, allowing for better fuel efficiency and higher stability at speed. Its wide width relative to height ensures a low center of gravity, which enhances balance during cornering and helps to mitigate body roll. The lightweight nature of the car also complements this aerodynamic design, although drivers should remain mindful of crosswinds at highway speeds given the car’s light curb weight.

The Honda S660’s small footprint and low weight make it exceptionally agile and easy to maneuver in congested city streets, tight parking spaces, and winding back roads. Its compact size means drivers experience excellent visibility and responsiveness, while the low seating position enhances the sporty feel. However, this compactness limits passenger comfort and cargo space, making it less practical for families or long-distance travel. The standard ground clearance and low profile require careful navigation over speed bumps or rough surfaces. Overall, the S660 is ideal as a fun, urban roadster that excels in short to medium distance driving with an emphasis on enjoyment rather than utility.
