For decades, Japan’s exclusive “Kei car” category has been a breeding ground for unique automotive innovation. Restricted by strict dimensions and a 660cc engine limit, Japanese engineers had to get creative to deliver true driving excitement.
The absolute pinnacle of this creative restriction? The Honda S660.
1. The Bloodline: Inheriting the Legend of the “Beat”
The story of the S660 doesn’t start in 2015; it breathes the DNA of the legendary 1990s Honda Beat—the mid-engine, naturally aspirated Kei roadster that was the last car personally approved by Soichiro Honda himself.
While the Beat relied on high-revving, naturally aspirated power, the S660 modernizes the formula. It takes that raw, open-top lightweight philosophy and pairs it with a modern turbocharged powerplant. It’s a direct link to the golden era of JDM, shrunk down to a size that makes every corner feel like a racetrack.
2. The “Mini NSX” Design Secret
Look closely at the sweeping lines, the aggressive front fascia, and the functional side air intakes. The S660 earned its global nickname, the “Mini NSX,” for a very definitive reason: it treats air exactly like its supercar big brother.
Instead of mounting the engine upfront like a standard commuter car, Honda engineers built a true MR (Mid-engine, Rear-wheel drive) layout. By placing the turbocharged engine directly behind the driver, they achieved an incredible 45:55 front-to-rear weight balance. It doesn’t just look like a baby supercar—it handles with the same razor-sharp rotation and physics-defying agility.
