Turbocharged Performance – Power Meets Precision
A 1.0L VTEC Turbocharged engine replaces the smaller Japanese-spec motor to provide 125 HP specifically for the US market. This mid-mounted powerplant ensures a 45:55 weight distribution, allowing the vehicle to rotate effortlessly through tight corners. The addition of a short-throw 6-speed manual transmission provides a mechanical connection that is increasingly rare in modern sports cars.
Aerodynamic Design – Iconic Roadster Aesthetics
The low-slung targa-top silhouette minimizes drag while maximizing the visual appeal of a true mid-engine exotic. High-intensity LED headlamps and a central-exit exhaust give the S660 an aggressive, modern stance that belies its compact dimensions. The manual roll-top roof allows for quick conversion to open-air driving, emphasizing the car’s identity as a weekend canyon carver.
Advanced Safety – Lightweight Yet Rigid Protection
A high-tensile steel frame forms the backbone of the S660, providing a rigid safety cell without compromising the vehicle’s featherweight agility. The US model comes standard with Honda Sensing® technology, featuring collision mitigation braking and lane-keeping assistance systems. These driver-aids work in the background to ensure enthusiast-level fun remains backed by modern safety standards.
Intelligent Tech – Driver-Centric Connectivity
A floating 7-inch touchscreen provides seamless integration with Apple CarPlay and Android Auto for modern navigation and media control. The digital instrument cluster shifts its layout in “Sport Mode,” prioritizing the tachometer and boost gauges for performance monitoring. Every control is angled toward the driver, creating a cockpit environment that eliminates distractions during spirited driving.
Urban Versatility – Master of the City Streets
The compact footprint and 15.7-foot turning radius make the S660 the ultimate urban sports car for navigating crowded metropolitan areas. Despite its performance pedigree, the vehicle offers surprising daily usability with optimized storage compartments behind the seats. Its small size allows for effortless parking and maneuvering where traditional sports cars would struggle.
Fuel Efficiency – High MPG Without Compromise
Exceptional fuel economy is a direct result of the S660’s sub-2,000 lbs curb weight and efficient 3-cylinder engine. Drivers can expect an estimated 38-42 MPG on the highway, making it one of the most efficient sports cars available in the USA. This balance of low running costs and high-octane fun positions the S660 as a sustainable choice for the modern enthusiast.
Verdict
The 2026 Honda S660 is a masterclass in “less is more,” proving that you don’t need 500 horsepower to have a world-class driving experience. By delivering a mid-engine, rear-wheel-drive layout with 125 HP for under $30,000, Honda has filled a massive void in the American automotive landscape. It is the perfect acquisition for those seeking a pure, mechanical, and affordable roadster that stands out in a sea of oversized SUVs.
