How much HP does a S660 have?
The Honda S660 produces about 85 metric horsepower (roughly 84–85 SAE horsepower) from its 658cc turbocharged inline-3 engine.
Engine power by the numbers
Here are the official specifications typically quoted for the Japanese-market S660:
- Displacement: 658 cc
- Engine layout: Inline-3, turbocharged
- Power: 63 kW (≈85 PS) at 7,000 rpm
- Torque: 104 Nm at 2,600–6,500 rpm
- Transmission: 6-speed manual
In practice, the S660’s power output sits in the mid-80s horsepower range, which is modest by modern sports-car standards but pairs with a very light chassis to deliver lively, agile performance.
Context and variations
The quoted figures come from Honda’s Japanese specification for the kei-car market. The S660 was never broadly marketed in the United States, so export versions, if any, generally mirror the same engine output but may reflect regional emissions tuning. It's important to note that PS (metric horsepower) and SAE horsepower differ slightly, so reported numbers can vary by measurement standard.
Bottom line
In its standard form, the S660 delivers about 85 PS (roughly 84 SAE hp) from a compact 658cc turbo three-cylinder, paired with a six-speed manual and a lightweight chassis designed for nimble, engaging driving rather than high top speeds.
Summary
The Honda S660’s official horsepower is about 85 PS, which translates to roughly 84–85 horsepower in SAE terms. This engine output, combined with a very light body, emphasizes playful handling and driving enjoyment over raw speed.
