2015-2022 Honda S660 0.7i (64 Hp)

The Honda S660 0.7i, producing 64 horsepower, was a mid-engined, rear-wheel drive roadster produced by Honda between April 2015 and March 2022. It represented a return to Honda’s roots in building small, sporty cars, evoking memories of the iconic Honda Beat from the 1990s. Specifically designed for the Japanese domestic market (JDM) initially, the S660 was later offered in limited numbers in other markets, including the United Kingdom and Australia. The 0.7i variant served as the entry point to the S660 range, prioritizing fuel efficiency and accessible performance over outright speed, and was positioned as a fun, affordable sports car.

Technical Specifications

Powertrain & Engine Architecture

The heart of the S660 0.7i is the S07A engine, a 658cc inline-three cylinder powerplant. This engine utilizes a single turbocharger with an intercooler to boost power output to 64 horsepower and 104 Nm (76.71 lb-ft) of torque. The engine employs multi-point fuel injection and a double overhead camshaft (DOHC) valvetrain. The turbocharger, while relatively small, provides a noticeable increase in power and responsiveness compared to a naturally aspirated engine of similar displacement. The engine is transversely mounted in the mid-engine layout, contributing to the car’s balanced handling characteristics. A 6-speed manual transmission was the only transmission option available for this variant, featuring close ratios designed to keep the engine in its optimal power band. The transmission’s short throw and precise feel enhance the driving experience, encouraging frequent gear changes to maintain momentum.

Driving Characteristics

The S660 0.7i, while not exceptionally quick, offers a surprisingly engaging driving experience. The lightweight construction (830 kg / 1829.84 lbs) and rear-wheel drive configuration contribute to nimble handling. The 6-speed manual transmission requires frequent shifting to maintain momentum, but the short throw and precise gate make it a rewarding process. The turbocharger provides a noticeable boost in the mid-range, but the engine can feel somewhat strained at higher RPMs. Compared to the more powerful S660 variants, the 0.7i prioritizes fuel economy and ease of driving over outright performance. It’s a car best enjoyed on winding roads at moderate speeds, where its agility and balanced chassis can be fully appreciated. The steering is direct and communicative, providing good feedback to the driver. The rear-wheel drive layout allows for a degree of playful oversteer, adding to the car’s fun factor.

Equipment & Trim Levels

The S660 0.7i was relatively sparsely equipped, reflecting its position as the entry-level model. Standard features typically included air conditioning, power windows, and a basic audio system. Interior upholstery was typically cloth. Optional extras included alloy wheels, a more sophisticated audio system, and various cosmetic enhancements. The dashboard layout was simple and functional, with a focus on providing essential driving information. The interior space is understandably limited, typical of a small roadster, and is best suited for two occupants. The focus was on providing a pure driving experience rather than luxurious amenities.

Chassis & Braking

The S660 utilizes a lightweight chassis with independent McPherson strut suspension at the front and a torsion beam setup at the rear. This suspension configuration provides a good balance between ride comfort and handling precision. Disc brakes are fitted to all four wheels, providing adequate stopping power for the car’s weight and performance. An Anti-lock Braking System (ABS) is standard. The relatively narrow tires (165/55 R15 or 195/45 R16) contribute to the car’s nimble handling but also limit grip in extreme conditions. The chassis was designed to be stiff and lightweight, maximizing responsiveness and minimizing body roll.

Market Reception & Comparison

The S660 0.7i was generally well-received by automotive critics, who praised its engaging driving dynamics and affordable price point. However, some critics noted its limited power output and small interior space. Compared to other small sports cars available at the time, such as the Mazda MX-5 Miata, the S660 offered a unique mid-engine driving experience. Its fuel economy of 4.7 l/100 km (50 US mpg) was a significant advantage, making it an attractive option for drivers seeking a fun and efficient sports car. Reliability reports have been generally positive, with the S07A engine proving to be a robust and dependable unit. The S660 carved out a niche for itself as a unique and enjoyable sports car, appealing to enthusiasts who valued driving experience over outright speed.

Legacy

The Honda S660, particularly the 0.7i variant, has gained a cult following among enthusiasts who appreciate its unique character and engaging driving experience. While production has ceased, the S660 remains a relatively affordable and accessible sports car in the used car market. The S07A engine, while small, has proven to be a reliable and durable unit, and maintenance costs are generally reasonable. The S660 represents a return to Honda’s roots in building small, sporty cars, and its legacy as a fun and engaging roadster is likely to endure for years to come. It stands as a testament to the idea that driving enjoyment doesn’t necessarily require a large engine or a high price tag.
