What is the safety rating of the Honda S660?
The Honda S660’s safety rating is typically listed as 4 stars in Japan’s JNCAP safety assessment. This rating reflects how the kei roadster performs in official tests for occupant protection and overall safety.
The S660 is a two-seat, open-top kei car produced by Honda mainly for the Japanese market, with limited international distribution. Its official safety evaluation comes from JNCAP, and there is no widely published Euro NCAP or IIHS rating for this model. The article below explains how the rating is determined and what it means for buyers and enthusiasts.
How JNCAP rates the S660
JNCAP’s scoring combines adult occupant protection, child occupant protection, and overall crash performance, with an overall star rating that summarizes the result. For the S660, public results have shown a 4-star overall rating in many model years, reflecting its safety features within the kei-car class. The breakdown helps illustrate how a lightweight, compact sports car performs in crashes and which safety elements contribute to the score.
- Adult occupant protection: typically 4 stars
- Child occupant protection: typically 4 stars
- Pedestrian protection: evaluated in some years and can influence the overall score
- Active safety features and structural design: dependent on year and trim; newer variants may include more aids
Before examining the breakdown, note that results can vary by model year and trim level. The following are representative categories from JNCAP assessments for the S660:
Exact figures can differ by the specific model year and configuration, so consult the JNCAP report for the precise rating of your S660 variant.
Global context and availability
Because the S660 was primarily marketed in Japan, there is no widely publicized Euro NCAP or IIHS rating for this model. JNCAP remains the primary official safety assessment for this car, and it is the main reference point for enthusiasts and buyers evaluating safety within its class.
What buyers should know
While the S660 benefits from Honda’s engineering and a relatively rigid chassis for a lightweight kei car, its open-top design and low mass influence crash dynamics differently than larger, heavier sports cars. When evaluating safety, consider the trim’s included safety equipment and any available active safety features, and remember that real-world protection depends on multiple factors beyond a single rating.
Summary
In short, the Honda S660’s safety rating centers on Japan’s JNCAP assessment, which has publicly indicated a 4-star overall rating for many iterations. There is no widely available Euro NCAP rating for this model, reflecting its Japan-focused market. For prospective buyers, the S660 offers solid safety performance within its kei-car class, augmented by Honda’s standard safety features where offered, while recognizing that its lightweight, open-top design affects crash dynamics relative to larger roadsters.
