What is the rpm of the Honda S660?
The Honda S660 revs to a redline of about 7,000 rpm, with peak power around 7,000 rpm and peak torque available from roughly 2,600 to 3,000 rpm. It uses a small, high-revving 660cc inline-3 designed for a light kei-car roadster feel.
Engine RPM profile
Understanding the S660’s rev range helps explain its performance character: strong acceleration comes from keeping the engine in its upper-rev band, while torque comes in early enough to assist daily driving without heavy throttle.
- Redline: about 7,000 rpm.
- Peak power: about 63 PS (46 kW) at 7,000 rpm.
- Peak torque: about 104 Nm (77 lb-ft) from 2,600–3,000 rpm.
- Engine composition: 660cc inline-3 (kei-class) with high-rev tuning for sport driving.
In practice, drivers often ride the revs toward the upper end of the range to access the engine’s peak power, while the early torque helps nascent acceleration out of corners or city streets.
What this means for driving
Because the S660 relies on a high-revving, small-displacement engine, smooth and timely gear changes are key to keeping the Rev Counter in the range where it makes the most power. The light chassis and balanced handling complement the rpm characteristics, delivering a spirited, communicative driving experience for enthusiasts who enjoy revving the engine.
Summary
The Honda S660’s engine is designed to rev to roughly 7,000 rpm, with peak torque around 2,600–3,000 rpm and peak power at 7,000 rpm. This combination defines its sporty, high-revving character within the kei-car class and informs how drivers should approach shifting and throttle application for optimal performance.
