The Honda S660 is a 660cc kei car engineered for pure driving engagement, featuring a 658cc DOHC VTEC engine producing 64PS and 108Nm of torque. Its defining characteristic is the 50:50 front-rear weight distribution and a low center of gravity, facilitated by a unibody construction with high-rigidity aluminum subframes. Factory options include the 'S' grade with a limited-slip differential, a 6-speed manual transmission, and a lightweight roll cage. The car utilizes a 4WD system with a Torsen center differential, allowing for precise torque vectoring. Enthusiasts value its tight 3.2m turning circle and the option to remove the rear seats for a dedicated track configuration. The chassis is tuned for high lateral grip, with stiffer dampers and a lower ride height compared to standard kei cars, making it a homologated special that rivals larger sports cars in agility and feedback.
AI-generated insights
The 658cc DOHC VTEC engine features a high-revving redline at 10,000 RPM, providing exceptional power-to-weight ratio and linear throttle response without the lag associated with turbocharged kei engines.
The chassis utilizes a multi-link rear suspension and a double wishbone front setup, offering superior geometric stability and reduced body roll compared to the torsion beam axles found in most competing kei cars.
The 'S' grade includes a factory-fitted limited-slip differential and a 6-speed manual gearbox, which are rare in the kei segment and significantly enhance cornering exit speed and driver control.
